Building an Oil Fired Foundry Furnace - Part 12: Installing the Insulation Blanket Wrap

[@Pierre-e3w]

Great work, Keith you are a professional and a great teacher, thank you so much for this superb project.

[@TonyHammitt]

Well, when a project IS the back burner, it's not surprising that it gets put there for a while :) The shop looks great, I'm jealous!

[@VintageMachinery]

But what a back burner it is !

[@MattsMotorz]

Oh man the furnace looks FANTASTIC! I cannot WAIT until you start doing some casting work!

[@VintageMachinery]

Thanks - we are really close now!

[@BisonWorkshop]

the seams just make it stronger. great job keith. nice to see you working in your new shop.

[@VintageMachinery]

Thanks - nice to have some time to work out there last weekend. I have been paying for that Monday holiday every since.....

[@dillydallydollcomachineand8246]

Knee Pads are a gift from above . They are great thanks for showing after a knee surgery and on the way show the young folk.

[@VintageMachinery]

Yeah, my knees really need them. I misplaced those knee pads for a couple of months but they turned up again a week or so ago. I have been missing them. I really like that particular pair and I cannot find another set like them....

[@dillydallydollcomachineand8246]

Look pretty similar to the pair I have gel or no .

[@murraystewartj]

Keith, had a great time watching this series (though my to-do list is now further behind). This project went like a lot of mine - start with a concept, tweak it a bit as it goes on, suffer setbacks (which in my case inspire language not suitable for children), regroup and keep learning. Whether you know it nor not, this series was not only educational but had moments of high drama: disappointment when the first inner form blew out, tension when the second inner form was so stubborn to release, and of course the sense of victory when the test firing went off so well. As with all of your pieces, a great combination of education, entertainment and inspiration. Looking forward to many more.

[@verdatum]

I am super excited to see this thing wrapped up and you do your first firing. It's been quite a journey. Keep up the great work!

[@VintageMachinery]

Moving along!

[@StreuB1]

Excellent!! Great to see you actually WORKING in your shop and not ON the shop! lol Almost there, can't wait to see it fired up! Thanks Keith!

[@VintageMachinery]

Thanks!

[@benhenry1116]

Did you do the next part

[@raincoast2396]

Looking good Keith. All it needs on that broad expanse of sheet metal is some stickers! Or one big Vintage Machinery sticker. Hope the actual metal melting can wait for cooler weather. Cheers.

[@VintageMachinery]

While that insulation should keep the exterior of the furnace relatively cool, I am not sure how stickers would handle the heat....

[@sirlancer23]

It's looking really good Keith!

[@VintageMachinery]

Thank you!

[@ravenhhca]

Have you done a video of the furnace in action? Looks like a winner BTW.

[@benhenry1116]

Nope still waiting

[@w056007568]

Smart looking furnace there. Well done.

[@VintageMachinery]

Thanks!

[@billdlv]

Looks good Keith, very well made.

[@VintageMachinery]

Thanks Bill!

[@alt-w7130]

Watching this video which is 2yrs old and is very interesting with your step by step detail. Thanks you.

[@robgerrits4097]

Looking very profesional now. Nice to see it working soon.

[@VintageMachinery]

Thanks Rob!

[@paulrjones3]

This has been a great series and learned a lot. Looking forward to seeing the casting work now that you are almost there. When cinching up parts like you did with the rope, I have found the use of adjustable web band clamps to be very handy. Thanks for the series.

[@VintageMachinery]

That would work just as well!

[@dinamboyz]

She's looking a beaut Keith. I can't wait to see her in action.

[@VintageMachinery]

Thank you!

[@wadehicks9270]

Mr Rucker you always bring us interesting videos thanks for sharing.

[@VintageMachinery]

Thank you!

[@roberthorner8494]

YOU HAD A ROUGH START ON THIS PROJECT, BUT YOU DID A GREAT JOB OF FINISHING IT. THANKS FOR THE VIDEO KEITH,

[@VintageMachinery]

Thank you!

[@tolydukhovny682]

that's one premium quality furnace! i am proud of your achievement, brother keith! thanks for the video, -toly

[@VintageMachinery]

Thanks Toly!

[@kevinbyrne4538]

Your ability to accomplish so much is an inspiration.

[@GuyBarry1]

woot! this is all leading to one thing (in my mind), and that is the completion of that beautiful safe restoration.. thanks for the update Keith

[@VintageMachinery]

I am ready to get that done!

[@GuyBarry1]

+Keith Rucker - VintageMachinery.org lol! no pressure, I can easily wait another year while enjoying all the other videos you make. I'm sure you are looking forward to completing the safe more than any of us, and no matter how long it takes will be worth the wait :)

[@danhale4926]

Great work Keith!

[@VintageMachinery]

Thank you!

[@americanpatriot2979]

I like this project. I can get into that kind of stuff since I worked in a foundry as a moulder & iron pourer.

[@josephmagedanz4070]

Hey Keith, The furnace turned out real nice. It was long "pourus interuptus" on the safe dials, but well worth the wait. Just look at what you got in the meantime: a furnace AND a shop. Can't beat that! Looking forward to seeing it in action. Joe

[@VintageMachinery]

Too many projects, not enough time or money....

[@exilfromsanity]

Very nice looking furnace and should work great too.

[@VintageMachinery]

Thank you!

[@hannesfuhringer5423]

Truly love your way of making and creating projects. Making small details as much professional as possible never halt to impress me. Once again. I love it! Greetz from Austria

[@noellwilson1273]

Hi Keith, I'm 74, retired, worked around furnaces on and off all m life. A few points: Curing - you want he water out and anything over 212F will do that. Anything close will help. A charcoal, or wood fire is safe and easy and not likely to blow up your refractory. Insulation - needs to be inside the steel shell. There is a temperature gradient from the 1200 F (?) inside to the outside air. 450F is pretty hot for the steel BUT, if you insulate the outside of the steel, you'll change the gradient, the sheet metal outside the ceramic blanket will now be exposed to outside air, and the steel between the hot refractory and the ceramic blanket will get closer to refractory temperature and may end up running red hot with greatly reduced life. If you are going to use crucibles inside the furnace, you may be able to use the ceramic blanket inside with a thin refractory wash and leave the outside steel exposed to outside air.

[@finnanfranklin417]

was wondering if there are any videos of you firing the furnace and melting steel?

[@Humanshoprag]

There's not i went through all his videos as of today he hasn't used it. I've built mine to the exact dimensions and materials. About to pour the lid this week. When i get it fired i will come back with a link

[@godfreypoon5148]

Gotta love how jigsaws are always so cooperative and pleasant to use on jobs like these.

[@VintageMachinery]

To make matters worse, the battery started getting weak towards the end of the cut and it was making it much harder to use...

[@shawnmrfixitlee6478]

Great job keith . Yur almost there , Can't wait to see the metal melting .. Brass should be no problem in that build ! Thumbs up ..

[@VintageMachinery]

Thanks Shawn!

[@ChrisB257]

Jigsawing thin sheet is a real PITA!! Reckon you needed a second pair of hands fitting it all up on the furnace. Doubt that outer skin will get much more than real warm. Look fwd to seeing things running.

[@VintageMachinery]

Yes it is. Also trying to position the blade over the hole that I could not see....

[@billsargent3407]

Keith, I have used this stuff for many years in the various equipment used for making Maple Syrup. I have on occasion had problems with mice getting into the stuff and making nests, always a special moment when setting up the evaporator.. I only mention it so you might keep it in mind when you tuck it away after usage. Mothballs or even just some duct tape over the blower hole might be in order. It looked like there was a mouse sized gap... Of course Ol' Josie, The South Georgia Swamp Panther might be a little more efficient then my lay-about barn cats!. Just an observation. As usual, great vid

[@billsargent3407]

Oops, just saw an early vid where you where reinforcing that spot, it was just the position of the camera that made me run my mouth... disregard

[@VintageMachinery]

Not a problem - good point none the less!

[@tomscorner3838]

Looks great Keith.

[@VintageMachinery]

Thank you!

[@Thunderstixx77]

Good job Keith !!! Thanks for posting it.

[@VintageMachinery]

And thank you for watching it!

[@bigun447]

All ready to fry some fish with that furnace. Maybe a crab boil. Probably could do that with the residual heat from a casting session. With a cast iron pour at the university we would wrap up a nice slab of meat in foil, bury it in the sand box covered by a layer of sand and the last of the iron would be poured over it. At the pour party that evening the meat would be dug out and turned into barbecue meat. Looks great. Almost to pretty to use.

[@VintageMachinery]

Down in my part of the world, we do what is called a "Low Country Boil" - shrimp, potatoes, onions, corn on the cob, ect. Good stuff!

[@wvrockcrusher]

Super nice furnace Keith! Been waiting a long time to see it this far along. You should make your first melt project a sign for the front entrance of the shop, something like "K. Rucker Machine Works" or something to give it an old time feeling about it. You could also blacksmith a nice hanging bracket for it, that would look great all painted up. Could be some good video material! Keep up the good work Keith! Jamie

[@VintageMachinery]

Not a bad idea!

[@TheOtherBill]

Who else tried to wipe the bug off their screen during the shot of the Cerablanket label? You got me with that one, Keith!

[@VintageMachinery]

What can I say, I live in South Georgia. We have lots of bugs....

[@k5at]

First class job, Keith! Thanks for sharing.

[@VintageMachinery]

Thanks Herb!

[@mcpheonixx]

+Keith Rucker - VintageMachinery.org omg the bugs! There is a saying here in South Georgia, the mosquitos are so big they can stand flat footed and mate with a turkey ! Bahduum Ttshhh

[@JesusvonNazaret]

can't wait to see the first projects with the furnace in use

[@VintageMachinery]

Thanks - me neither!

[@eggnogfrog]

Can't wait to see you fire it up!!

[@VintageMachinery]

Hopefully soon...

[@PaulTunnicliffeChannel]

Perfection takes time. Looks great Keith I can't wait to see you fire it up.

[@VintageMachinery]

Not sure it will qualify as "perfection", but it should be more than functional. Perfection would probably require a couple of versions to work out the kinks...

[@JohnBare747]

Great to see the furnace about done, it rally looks nice Keith, but for sure the shop had to pe your priority. Looking forward to seeing some molten metal in the near future. Good job.

[@VintageMachinery]

As am I - I am anxious to pour some brass!

[@JohnBare747]

Just something about brass, it just has that nice heft in your hand and a feeling of a quality part. I was just sorting through some old brass grease cups oilers and other brass pipe fittings and I know some of them are well over a hundred years old and they are still sweet. They don't make them like that anymore. .

[@GermanToolReviews]

Great job on the furnace Keith.

[@VintageMachinery]

Thanks!

[@kevCarrico]

a great way to cinch things with string or rope is to have a loop on one end (like you did), and add a loop BACK from the other end -- then you can pull the string through BOTH loops and really cinch it tight (force the loops toward each other). great work!!

[@chemech]

Keith, That's about how our refractory installation contractors at work do the job of installing CF blanket... there's really no other way to go about doing it right... Thermal Ceramics (these days Morgan Thermal Ceramics) Cerablanket, and Harbison-Walker's Superwool are both good products for this kind of application. You should be fine with the 8 lb/cuft material... if for some reason, you find that it's getting torn - unlikely once you've covered it with sheet metal - the 12 lb/cuft material is a little bit stronger mechanically, if a bit less of an insulator and a bit more expensive. Looks like good work, and you won't be abusing this the way the guys in a mine or smelter would... Cheers, Eric

[@VintageMachinery]

I think it should hold up fine. Time will tell!

[@johnferguson7235]

Wrangling sheet metal is another one of those jobs where you need that third hand. I remember when you ran into the issue with the side supporting straps needing to be cut so that the furnace can expand when it is heated. Will the sheet metal skin have similar problems or can it sort of float, riding on the support straps? This is a great DIY project; saving a lot of money and creating a chance to have some real fun.

[@VintageMachinery]

Will, first off, we did not see any expansion when we test fired it, so I don't think expansion is really an issue. But with that said, the skin should ride right along with the supports and move up and down with the furnace should it try to move.

[@johnferguson7235]

Keith Rucker - VintageMachinery.org The furnace turned out looking very nice. I bet that it will be used for decades. Whoever gets to work with it will appreciate the time and effort you put into the project. I went to college with a fellow who made his own glass blowing furnace and used it to make stained glass to repair the windows from old churches. The university still uses his furnace 30 years later.

[@dhamma58]

If you have a good sheet metal guy, that seems a good way to go. All parts match and a crimped edge with tabs to fasten would be sure to take the heat. In my construction days, one of my most cherished subs was sheet metal. He solved many a problematic design flaw in the plans....

[@VintageMachinery]

My sheet metal guy is really good. He knows his stuff and is amazing to watch work out a problem.

[@TorgeirFredriksen]

Hi Keith. Just watched all 12 videos in this playlist but could not find any where you actually tried it out. Do you have any videos where you actually melt or cast something?

[@seanflanagan5674]

I am SO glad to see you working on the furnace again -- just in time for summer! I'm surprised you didn't use a Trucker's hitch while you were fitting the skin.

[@VintageMachinery]

I am ready to knock this project out!

[@mouseriverengineering]

Fine work can't wait to see it running been wanting to do the same thing for a while

[@VintageMachinery]

Moving in the right direction again!

[@lewiemcneely9143]

Looks like a pro job to me, especially where it's sitting!

[@VintageMachinery]

Thank you!

[@connierhodes5414]

So glad to see you getting your new shop tooled, a friend of mine is selling off his uncle's estate!! You may be interested in these several flasks, a flask press, a couple sand mullers, a sand conveyer, a couple of band saws, a giant furnace and many more items!! He will make you a smokin deal on all of it or just some of it!! If you think you may be interested just comment and I will send you my contact info at that time!! I also want to thank you for your video's I enjoy every one of them!!

[@VintageMachinery]

Interested - well, yeah, I am am interested. But with me trying to save money to put insulation in the shop, I probably won't be spending any money on new toys for a while.....

[@connierhodes5414]

I totally understand, just keep it in mind and holler at me if things change, like I said it will be awesome prices for you!!

[@RoelTyros]

Hello Keith, The furnace is looking professional now with the metal sheet around it and I am curious about how it performs. Looking forward to the first time you're gonna melt iron in it, always scary to see but interesting. Scary because of those high temperatures and that red hot iron, and I don't want to think about the burning on skin eeks. I hope the storm is not getting to your place but that you get only a bit normal rain from it. Here it is now sunny but they forecasted that there will still be thunderstorms later in the day. Anyway great video and looking forward to the final part ! Many greetings from Roel !

[@VintageMachinery]

We will probably start with melting some aluminum and brass before moving up to cast iron, but we should be able to get there. As for the storm, we are getting some nice light rain this morning and are expecting thunderstorms all day long. They are saying about 2-4 inches of rain. As long as it does not come too fast, we should be fine - we are really dry around here, so the farmers will welcome some of it.

[@FastEddie007007]

Good job as a tin wrangler. If I would have done that, I would have to paint it red to cover the blood.

[@VintageMachinery]

I hope there is not blood to cover....

[@GreatNorthWoodsHillbilly]

Next time you need to bend metal around a round shape, try a ratchet strap instead of rope, works so much better. The furnace looks great, must feel good to work on a project in the new shop.

[@VintageMachinery]

A ratchet strap would have been fine too, but the rope trick worked great!

[@gk6993]

Keith. Great work. Looks just like a bought one. Not that I've seen any. So much care you've put into this. Frankly it's inspiring. Would this be capable of melting steel, or do you need higher temperatures for that? Looking forward to future videos. Thanks.

[@Rich206L]

Keith, What an unexpected Monday morning surprise! Your first project in the new shop. I guess that when you use it, it will have to be outside, right? It looks great and like everyone else, I can't wait to see it in action. Regards, Rich

[@VintageMachinery]

Yes, outside. I have no plans to burn my new shop down!

[@Rich206L]

Ha, ha, I suspected as much! I can't wait for you to cast that brass for the safe dial! :)

[@dennyskerb4992]

Hey Keith, great job on the furnace. Thanks for not editing out the jigsaw, this stuff happens.

[@PeterWMeek]

Nibblers work really well for cutting small holes in sheet metal. Power nibblers will save getting hand cramps when doing a lot of it.

[@jusb1066]

yes it was cutting a smaller hole so the blade was binding, cant avoid it really, better to show it , i agree

[@VintageMachinery]

That was the way things went....

[@VintageMachinery]

A nibbler would be nice....

[@halfinchholes88]

Loved seeing the extra effort with 1/4 - 20 screws for the sheet metal attachment. I've done it many times too. True mark of a machinist/toolmaker. When you get gutsy, try chucking up the tap in the cordless drill. Only tighten the chuck JUST enough to tap but, NOT enough to break the tap. A little Moly Dee, forward slowly till threaded, back out in reverse. Almost as easy as threading on a mill. Be sure to use a good spiral point gun tap. Then again, you probably did this off camera... Keep up the good work.

[@VintageMachinery]

I did not try tapping it with the drill on this job, but I have done it in the past. Always afraid I am going to break those small taps though...

[@TheKnacklersWorkshop]

Hi Keith, Four years later do you still use the furnace? Take care Paul,,

[@outsidescrewball]

Enjoyed....did you get black overspray on your new concrete approach.....lol

[@AmateurRedneckWorkshop]

I was wondering where the furnace went. I want to see some hot metal come out of it. Keep on keeping on.

[@VintageMachinery]

Working in that direction!

[@RjBin-xz2um]

Furnace looks great! You finished it in your shop to ;)

[@VintageMachinery]

Yep, nice to do some work out there!

[@andymandyandsheba4571]

looking good keith

[@VintageMachinery]

Thanks!

[@Lakesidearmorer]

Looking good Keith. Congrats on your first 'new shop' project ;

[@VintageMachinery]

Thank you!

[@charlescompton4495]

Oh shoot,we forgot the blacksmith corner! Well Keith, I guess you'll have to add that later. Have a great week, Greg.

[@VintageMachinery]

I was thinking of putting a blacksmith shop outside under a lean shed on the shop. When I get to build the lean to shed that is....

[@billdoodson4232]

I know I'm 7 years too late. However, to fit the casing metal and pull it up, use a couple of the cheap lightweight ratchet straps. They really work well to tighten and then pull in to allow you to pop rivet the seam.

[@highdesertworkshop]

What works well for cutting thin material with a reciprocating saw is a piece of Styrofoam a little thicker than the length of the blade ofthe saw on the table under the material. The blade goes through the foam harmlessly and it provides a stable platform for the material. The inside of an old hot tub cover is what I use. Other peoples trash is my treasure.

[@VintageMachinery]

Nice tip!

[@roncartwright8125]

Great Furnace, Have you decided what your first project is going to be. I am looking forward to it.

[@VintageMachinery]

Gotta finish the safe dial - that is first on the list...

[@derKarl_stp]

I might have used self tapping metal working screws instead of regular screws in tapped holes... they are pretty cheap over here in Europe and you only have to drill a hole and screw them in... and the yhave a lot of strength anyways a nice construction and pretty interesting to see the other steps following Keith :-) and are you adding some insulation to the lid as well? if you do so, you could cut up the rest of the not used insulation (6 inch strip) into cake slices

[@VintageMachinery]

Yes, I plan to put some insulation in the lid as well. I have plenty of extra...

[@mrfrog3350]

The furnace came out great Keith.I'm guessing you will be using waste oil to fire it. It's always listed free on craigslist here in Detroit.

[@VintageMachinery]

Yes, it will burn waste oil, but I will probably fire it on Diesel fuel the first time. I don't have any waste oil handy or a way to store it right now.

[@mikeharmon4901]

hOW DID IT TURN OUT AND DID IT HOLD UP?????????????????? I watched whole series :)

[@wyrtwister4260]

Try self drilling Teak screws . Looking forward to seeing the 1st video of the furnac's first melt . :-) God bless Wyr

[@jaratt85]

small ratchet straps are highly useful in such a sitiation.

[@VintageMachinery]

Yes, those would work great as well.

[@mikedavis5397]

Nice job ! I was wondering if the outer jacket of a water heater would work. It appears that maybe they are powder coated.. What ya think ?

[@jusb1066]

they maybe alumnium also, or at least the paint might not hold up to it.

[@VintageMachinery]

That would work fine I would think.

[@MatthewTinker-au-pont-blanc]

Keith, I'm surprised that you didn't wear a mask when you were working with the ceramic fibre. This stuff is bad for your lungs! It is a considered to be a Carcinogens. Now that it's nicely locked away inside that sheet metal casing it's out of harms way! Thanks for another great video, Matthew.

[@ScottandTera]

looks great keith wonder how well steel banding would have worked like they use on lumber loving the shop

[@VintageMachinery]

I don't see why it would not work.

[@russtuff]

Did you release plans, cut list, etc for this.

[@billsargent3407]

Hopefully this leads to the dials for your safe!

[@VintageMachinery]

That is the plan!

[@wilddhc2]

That's the way I saw this project headed.

[@marceltimmers1290]

Hi mate. I was a bit worried that you would run out of space, in those cramped quarters of yours. But fortunately you were able to manage, thank goodness. Will you build a chimenea for it, so you can use it inside on cold and rainy days?

[@VintageMachinery]

I will probably just roll it outside on the pallet jack when I want to fire her up.

[@marceltimmers1290]

Fair enough, I had that vision of a 19th century foundry, with sparks flying everywhere casting a new locomotif. Alas, it's not to be ; (

[@ericwolf5874]

I really like how it is coming together Keith. What are you going to do for a crucible and tongs, build or buy? Also, where did you get your insulation?

[@VintageMachinery]

I have a crucible already, but no tongs. I am going to talk to our blacksmith at the museum about building me some tongs. As for the insulation, I was able to find it easily on the internet. I actually ended up buying this box off of ebay because I found somebody selling some stuff they did not need for a lot cheaper than from a dealer - it was brand new stuff still sealed up in the original box.

[@mainengines]

Finally! Well I think I will LOL - thanks Keith.

[@VintageMachinery]

Thanks!

[@dougbourdo2589]

That sure isn't your average backyard furnace. Next thing, Keith will be pulling white-hot billets & forging something cool.

[@bobrobert6277]

can't wait to see you use that thing :)

[@VintageMachinery]

Thanks - it should be coming soon now!

[@wfinch1138]

Did you think about putting the gas inlet on the other side? It seems like it will get underfoot where you will be opening and closing the lid. Or is it not as in the way as it seems?

[@VintageMachinery]

It is actually more out of the way there I think.

[@TM-dh2xb]

No videos of the final product in use?

[@bulletproofpepper2]

Great work! What are you going to cast first?? Thanks for sharing.

[@mrbluenun]

Hi Keith, No need to reply, just to say congrats on what you have done and I think you are right to isolate the wood-dust from the metal swarf. I am not too sure whether it is a good idea to link the two with a powerful fan though. That kind of defeats the objective principle of keeping the two areas separate in my opinion. Though I guess a fan blowing from the at the Area into the Woodwork Shop could be OK, the problem you might have to to make airborne the dust which has found a nice cosy bed on the rafters and cross-braces. Just a suggestion, could you or have you planned on an air duct to either just blow the saw-dust outside, or ave the fan you mentioned pus air out through the dust duct in the woodwork Shop? Just a thought, and it really is something I grabbed from the air as I am no expert but as an ex builder for all my life I have a few ideas, of course things, designs and County Rules vary as much across America as they do around the world. I am assuming you will be fitting plywood or similar over the Insulation? Good luck, I know it seems like a long time coming to be completely ready wired and finish as per the plans but it is an awful large building.

[@VintageMachinery]

I am on the fence on the fan up there, but I figured it was easier to frame it in now than later - not a problem to cover it up....

[@PeterWMeek]

Nice looking furnace. I usually get too impatient to finish with the detail work like painting.

[@VintageMachinery]

I hate painting....

[@PeterWMeek]

I once chose to dig out a cess pit rather than paint a dog-house-sized dormer. I never regretted making that choice. I really hate painting.

[@holyblood1]

good job, tanks for sharing.

[@VintageMachinery]

Thanks for watchings!

[@holyblood1]

all the tanks to you for all the amazing job you do

[@kokodin5895]

barrel of hellfire is almost ready,yey, i can't wait to see first cast iron melt :]

[@VintageMachinery]

We will probably start with aluminum and brass before moving up to cast iron, but I see that in my future!

[@dansw0rkshop]

Did you ever get to run this on diesel fuel?

[@ROTTK9]

Victor Safe restoration - casting, was there a 2nd set of casts made, I am not seeing another video listed for it yet.

[@Reese_Asher]

*Is there any particular reason why you used the jigsaw instead of the plasma cutter to cut out the circle?*

[@VintageMachinery]

Yeah - one big reason. I don't have a plasma cutter.....

[@doitmanrv1084]

WHAT HAPPENED WHEN ARE YOU GOING TO FRIE IT UP ?

[@travisshrewsbury7169]

looks great,make a lot of fishing sinkers with that,lol

[@VintageMachinery]

That will sure do a lot of sinkers -in a hurry...

[@robertkutz]

keith looking good.

[@VintageMachinery]

Thank you!

[@benhenry1116]

what kind of crucible do you need for melting iron or steel.

[@TritonAquascapes]

Just curious why you didn't just use self tapping screws?

[@chemech]

Probably because he wants to be able to take it apart and put it back together at need...

[@VintageMachinery]

The pieces I was drilling into were about 1/4" thick - a bit much for self tapping screws. They work great in thinner material.

[@TritonAquascapes]

Right on, thanks for responding.
