[@3347861]

Thanks again, Adam. It's always a pleasure to sit in your classroom!

[@phineasrumson3116]

I am amazed at the level of skill that you possess. Every video that you present teaches me something new! Many thanks, sir.

[@Abom79]

+Phineas Rumson Thanks!

[@raincoast2396]

The 'before & after' images always amaze me! You do good work, thanks again Adam.

Really enjoyed this episode Adam. Thanks also for being a guest on the podcast and for sharing your work with us.

[@Abom79]

+thecogwheel I enjoyed it! Good times and conversations. 👍🏻

[@ShawnAndera]

Just listened to your podcast. Great conversation. You brought up the one question I was dying to hear. It makes me wonder if we will be seeing more of Avon79 in the future. Lol. Have you guys tried interviewing AVe?

[@viscache1]

Thanks for another fine video! I really like how you talk through each step. Those of us who learned from lesser gods can pick up clever hints and things that can be done to improve our projects. Great editing with a stable camera stand to boot!

[@paultopolski1978]

Adam, You have shown the tip to shear off the sharp edge in a mill vise before and I have used this tip. I made a bunch of stainless spacers to modify my jerky slicer to cut thinner strips. Thanks for the tip! it works great.

[@afpienaar4604]

Thank you Adam . Also thanks to your employers for allowing us a glimpse into your world . A place that allows our world to function A F Pienaar Johannesburg

[@onlooker251]

Adam - you make it look so easy! Those surface finishes are so good on the turned parts. I like to see ‘real’ engineering. Thanks for your time to share this with us. John

[@musicbro8225]

I listened to the blog and enjoyed it very much. I feel like I know you better, not any different to whom I always thought you were but better. It was interesting hearing you talking about your video making and how you are so passionate about the process (I imagine you view a finished video not unlike a finished piece of machining work). Believe me, I understand how much work goes into what you create for your youtube followers and I admire the quality of your work, you have a great talent, it's no wonder you have so many people following your channel and I'm glad to include myself among them. Peter

[@Abom79]

+Music Bro Thanks brah! I comb through the videos once I have all the edits done to try and make sure I didn’t miss anything. I enjoy a good quality production, even from a home gamer like myself.

[@olegtodorov-mihaylov2149]

Real pleasure following this cannel mate...one of the best machining if not The best machining content on the Internet.

[@johnnyholland8765]

Speaking of holes being drilled...... I drilled the smallest holes I have ever drilled yesterday. They were .010 in dia. Used a "Servo" brand mini drill and a microscope. They were in a new valve body we are building. Talk about pecking away at something. Like you I got it done. Another great video Adam. Glad Motion will let you film again.

[@Abom79]

+Johnny Holland I still can’t see myself using a cutter that small. I actually have some drills that are .006 in diameter that someone give me.

[@dessilverson161]

A friend is in aviation engineering and some the company is in the States and some in the UK. Always competition as you can imagine. The states machined a piece 0.1 thousandths diameter and sent it to the UK. My mate, drilled it, tapped it, and put a bolt in it and sent it back to them. Now that is minute engineering. Des. Love the work by the way.

[@TheJoyofPrecision]

Adam, thanks for joining Justin and I on the podcast, we had a great time! Great SNS, this one was packed full of awesome horizontal boring mill work. :-) Oh and I also really like those screw machine drills and use them pretty often.

[@Abom79]

+The Joy of Precision I enjoyed being on the podcast Max, thanks for inviting me. If y’all want to chat again one day just let me know. I thought you’d like the boring mill action this week. 👍🏻

[@howder1951]

13:30 nice rotation protection Adam, I shudder to think of that jumbo shaft slipping under drilling torque, nice! Enjoyed the time on the boring mill, thanks.

[@robertevans6481]

Always a enjoyment to watch you turn....and mill...have a great weekend Adam

[@michaelkolb6142]

Thanks always a pleasure to watch a professional. I wish I could have seen you find the location of those equally spaced holes.

[@u238sub0]

Adam - love your vids. You are keeping American ingenuity and know-how alive.

[@ctjctj2]

The Noga Mists come with two hoses and and output. The hoses are both 1m long, one is your air intake and the other is the siphon hose. Noga sells a 2m hose as well. For me the distance from the head of the Bridgeport to the tank was a bit more than 1m so I was always fighting to have the tank in the right place. I ordered the 2m hose from MSC Direct, took a while as they had to special order it from Noga but the did deliver it after a while. The 2m doesn't work as well because of the distance of lift but it did allow me to position the tank up off the ground behind the Bridgeport which works nearly flawlessly. Also, if you have an unheated shop, remember that the coolant can freeze so you might need to take the entire system into a temperature controlled area.

[@johnstrange6799]

The finish on that pillow block casting was gorgeous. Thanks for another Saturday night. :)

[@Abom79]

+John Strange Thanks John

[@ROBRENZ]

Great video Adam! I Really enjoyed your home shop machinist podcast and look forward to your return visit. Thanks for your very kind words. ATB, Robin

[@weshowe51]

I have a full set of fraction, number and letter screw-machine length drill bits. If you have a smaller than ABOM size mill, they are extremely useful for big things where you don't have a lot of room left over when you clamp it to the table. They are also really nice when you power tap because they are not much longer than the tap, less knee or head travel when switching bits.

[@Abom79]

Good point, great to use when height is limited in the mill.

[@randomdude1786]

your videos are just awesome adam I gotta get a computer with hdmi so watch instead of satellite cable. love the stuby drills the boring mill jobs are always entertaining.complex set of holes there lot of tools lined up on the tool board lot of tool changes I sighed just looking at it. love it . new shops getting pretty close cant wait myself keep it up adam

[@marinizo1]

I watched many of your videos, they are not professional but it is clear that you are a perfectionist and you do some work of grade 20

[@postimulle]

I see a lot of YT machining community members quitting making videos. Or at least slowing down. I really appreciate you still keep going. I always have great time watching your videos. Keep up the good work!

[@Blazer02LS]

That is due to YT being morons and blocking videos for no good reason or demonetizing them until they hit 1000 views THEN they review them and by that time most of the folks who watch are finished so the creator loses big money.

[@postimulle]

I don't know anything about YT business side but I enjoy wathcing these guys do what they do and learning something. I really hope YT policies don't make them quit making these videos.

[@Abom79]

+postimulle I still enjoy making my video and do it as often as time allows me. I strive to at least give my viewers one video a week.

[@petersmith3703]

Sets and clearly explains the excellent work -I find it fascinating to watch and also learning of proper standards. . Many thanks for great work. Cheers

[@hopper1]

I really enjoy the HSM podcast. They've had some great guest hosts. Highly recommended.

[@Abom79]

+hopper1 Thanks!

[@tyhuffman5447]

I'm a vibe guy and it amazes me to see huge steel shafts and I have to remember that shaft has a geometric center and a center of mass and they are rarely in the same location. At resonance that shaft and everything it's connected to becomes very loose. Some of those shafts will grow and contract with the heat of the day, with some the difference is in inches of growth or contraction. Plus the shaft bends into the load zone. Hard to think of a 12" or 24" or 36" shaft bending, but it does, hard to think of them becoming as loose as a noodle but they do in resonance.

[@Pow3llMorgan]

I went out tonight to find a deep hole to tap. Joke's on me because I didn't get any and here I am watching Abom vids again.

[@jimzivny1554]

Great SnS. Nice work on those deep holes, they can squirrelly fast if a bit starts to wander. Adam I wanted to thank you, a few videos ago you mentioned a book you use for reference "Pocket Ref" by Thomas Glover. I purchased a like new copy from an Amazon used book seller for $7.00 including shipping. Fantastic book, packed with tons of assorted info. I'm constantly adding to my automotive, metalworking and machinery library and its a great addition. Thanks for sharing.

[@Abom79]

+James Zivny Your welcome James. 👍🏻

[@charlescartwright6367]

Nice job Adam, thanks for sharing your work and tips.

[@NuclearHedgehog]

Good video. Hope you get things rolling smoothly with the concrete pour.

[@TheDJHeadless]

I've been working the knobs for almost ten years, I hope to be half the machinist you are one day.

[@mountainviews5025]

I'm sitting here watching you and I really appreciate you hand tapping the bolt holes I thought that all young guys stopped doing that LOL lol LOL lol I appreciate your quality of work

[@bcbloc02]

Thats a good lucking shaft! My [;ates I am making for my HBM are 4140 and it works out nice.

[@maxcnc777]

I've used the kool mist 77 and 78 for years. The 77 tends to leave a bit of a gooey build up on ways and what not when you mix it rich.. but it's a great product.

[@347chas]

Hi Adam, love your videos & the work that you do, thats some gearbox shaft, dont know if its possible on any of the work that you do, but would be great to see the item/s installed so we get some idear that they are used in.

[@Abom79]

+347chas I’m going to try and get a few clips as the gearbox goes together.

[@THEIRONWORKER]

The hole pattern job eat up about a day of time on the Kearns . I like to see the boring mill at work because I have one also Thanks Adam

[@williamdubay2125]

Ever do a cast iron sharps receiver? 29mm-2.5 metric square thread. Sounds like fun and a challenge for our old equipment..

[@peterdyer9640]

Hi Adam it is a real pleasure watching your

[@zippy3711]

Wow, never saw that done. That is a great thread job.

[@jtjjbannie]

I would get fired for taking that long to do that job. You are truly blessed my man.

[@melvinschmecklebak3766]

Amazing machining work Adam. Enjoy your vids always

[@177racing]

I love hard work, I could watch it all day!!

[@alex4alexn]

love watching you on the big pieces!!! keep up the great work

[@turbocobra]

Awesome sir, really enjoyed this SNS. Curious if your sales people at Motion ever involve you in the bid process for jobs like this? Like what material, how many hours, etc. Also, do you charge the customer for any special tooling that needs to be ordered, or does the tooling just get absorbed into your overhead of the company because you can use it on other jobs in the future?

[@Abom79]

+Ramsey Customs - turbocobra Gary, many times on these larger shaft we get quotes from manufacturers on them. If they are ridiculously expensive we can usually make them in house for less. The technicians will quote the job with plenty of time for the rebuild and allocate some of that for me to build the shaft. Once it’s done we’ll get together on the time I spent and document it. Special tooling needed to machine it will be included in the quote. More daily use tools are bought on expense.

[@JaakkoF]

Get spotting drills for hole starters, they usually have a slightly larger included angle than normal drill for perfect centering. Extremely short or just shorten to suit and in some places called "NC drills".

[@RookieLock]

I really enjoyed the voice over stuff in this video! I wouldn't mind seeing more of that!

[@Abom79]

+Rookie Lock Thanks, I do it when I need to add in some info about the vids.

[@sibranowitschbrimborium282]

Ich kann mich echt totlachen wie gut dass er das im Griff hat und das ist echt speziell leute wenn ihr jemals jemand an meine Maschine gestanden habt ist er der Beste

Some very nice work and nice jobs.

[@Abom79]

+Randy Richard In The Shop Thanks Randy.

[@matthewpeters325]

Hey I'm just a dumb welder fabricator guy and i love learning new stuff so I'm sorry for my dumb questions but hey that's how you learn. Why did you sometimes use oil when you cut parts and other times no oil? And my other question is when your cutting threads how does the machine not cross thread meaning how does the machine know when to start cutting so it doesn't start at another point on the threads and then cross thread?. When ever you have time of you could educate me. Thanks Matthew Peters

[@TheSteelArmadillo]

I hope you're proud of your work. I'd certainly be proud to run your parts in my equipment.

[@Abom79]

+Jesse Smith Thanks!

[@erikdevaney4781]

hey ABOM, i just watched a guy that used a Tree taper boring head on the milling machine to bore tapered holes for a rack to hold Cat 40 tool holders. do you have a tool like this or have ever showed a video using one. i know you used the monarch with the taper attachment though

[@christianfeldmann8287]

[@lencost1]

Hay Adam! Did you save the Babbitt chips for Keith Rucker? He pours Babbitt bearings!

[@davidwells4267]

Especially with that being a long tap why didn't you get a backward and break the chips?

[@kellerrobert80]

Great work, Adam. Keep it up.

[@williamgarrett2931]

Simply outstanding video's! I'm hooked!

[@Abom79]

+William Garrett Thank you!

[@jamest.5001]

I got a crazy dumb question, would there be any advantage to drill then ream a hole to be tapped?

[@dougankrum3328]

...That Trinco Blast cabinet...that stuff is top quality...don't give it away...!

[@Abom79]

+Doug Ankrum Not planning on that, gotta find the right buyer in the market.

[@dougankrum3328]

Thanks for taking the time to reply...I'm moving to a property with a 32X40 completely open space 'shop' with 12' Ceiling......I'm in N. Calif....other wise I'd grab that ....! I never miss any of your Videos, really good stuff......

Another great SNS Adam !

[@kenwhite5132]

That was a cool angle 😎 👌 it looked like a big ass cylinder for a 10 round revolver..... lol 😆... the-- cal abom79...

I really enjoyed the podcast. Nice chat there. Cheers!

[@Abom79]

Thanks...that was fun!

[@swarfrat311]

Adam, Another great SNS! Thanks! When will you and Abbey be making another weekend drive/video segment? Thanks, again. Have a good one! Dave

[@Abom79]

+Swarf Rat Hipefully soon, but that’ll just happen when we get a chance. Traveling to Georgia in November.

[@shawnmrfixitlee6478]

very cool share Adam ! Enjoyed ..

[@bengress]

Have you ever used Boelube? it’s more common in aviation.

[@RyeHillBaptistChurch]

Great Vid Adam! Guess this is part of the "Second Shift". LOL Enjoyed it man, keep up the Great work.

[@davids2928]

Greetings, Awesome vid! Could you talk about pricing for some of these larger jobs. Is it mostly base on machining time, material, tooling, design, or what? My new job requires me to design large things out of metal and would info on that side of things. Could make for a boring video so maybe just sprinkle it in? Thanks and will be watching!

[@Abom79]

One thing I can't talk about with customer work.

[@martineastburn3679]

I use MSCdirect.com and a little McMaster. I think they are the two giants. I love the use of that indicator, I have one and thought it was only for the mill. Wow nice classroom.

[@ronalddavis]

When you mark a drill bit like that for a cutting depth do you measure from the end of the bit or from the cutting flutes?

[@Abom79]

+ronald davis I usually measure from the edge of the flute.

[@maikeydii]

Any particular reason for using straight fluted tap for blind hole (ie. that was the only one available)? What I've been taught is to use spiral fluted taps for blind holes.

[@Abom79]

+mikey_d It’s what I found to use

[@GigsTaggart]

Are those red sparks ok or normal on 4140? ive only seen red sparks when things are going very wrong but that lathe is a beast compared to mine.

[@killermacmc]

Adam, what's the process for cleaning up when done with taps and drills? Do you degrease and leave bare, or just a wipe-down, having a layer of the cutting oil on?

[@Abom79]

Typically I blow them off, or wipe them off leaving a film of cutting oil on them though.

[@hinz1]

That babbitt alloy makes quite nice chips

[@Abom79]

+Chuck Norris Just like cutting lead 😎

[@sithus1966]

I want to mention something about KBC tools. If you are not ordering a ton of stuff, they have shipping for $8.95. While they do have a $25 minimum order, I have found this shipping rate to be a whole lot cheaper than a lot of tool sellers. Most I have found will charge you $15+, no matter what you order.

[@Abom79]

+Sithus1966 good point made, they advertise this on there home page. 👍🏻

[@realfixesrealproblemssewel82]

Hello there from England. I'm not being ignorant but can anybody tell me why sometimes it sounds like an interrupted cut even on a clean , what appears to be perfectly round stock?? Is there a flywheel of sorts anywhere in the machine. I'm pretty sure that there isn't? Thanks in advance if anyone can tell me.

[@THYKAER]

Why did you not just use the milling machine for the drilling ? I dont know any thing about this... just curious

[@Abom79]

+Jacob Thykær Much easier and more rigid in the boring mill.

[@ruperthartop7202]

Great content as always. Cheers Adam

[@brand-x7049]

Just out of curiosity: on that babbitt bearing you're boring out, would just melting the babbitt out with a brazing torch work? That way all you'd have to do is bore the castings to size, rather than having to take multiple passes to cut out the bearing material, and you could catch and save the babbitt if you wanted.

[@aidanrocks13able]

Brand-X It would work, but it would make quite a mess and possibly screw up the paint on the housing.

[@Abom79]

+Brand-X I like to center up on the bearing where the factory bores it. I have no use for the Babbitt.

[@brand-x7049]

Aw ite den. :)

[@barrygerbracht5077]

Looks like a Gatling gun barrel from the end LOL. Nice work.

[@stevenacarter77]

outstanding deep bore & taping

[@Ujeb08]

Hey Adam, How did you like that Hertel Tap? I've had some bad experiences with Hertel. I prefer Cleveland drill bits, but I gave Hertel drill bits a try. I have for years drilled cross holes in 300series stainless steel shafts for holding 1/16" diameter spring pins using cleveland drills at 2000 rpm and cutting fluid - with no problem. Tried the hertel bits and nothing but problems. tried slowing down the spindle speed, heavier feed, etc... But I kept breaking bit after bit. switched over to the Cleveland bit and it cut like butter. I threw away over a hundred of the 1/16" Hertel drill bits - not worth the trouble.

[@Abom79]

+Ujeb08 This Tap was good, and ground nice. It was what we found to buy. I have not used the Hertel drills.

[@billdlv]

Nice job Adam.

[@leonardoruizgonzalez7466]

Hola Me gustan mucho todos los videos y los trabajos tan bien echos un abrazo des de muy lejos .Huelva. Andalucia.España.

[@blackflagqwerty]

I wish McMaster shipped worldwide!

[@jamieknowlesknowles4001]

What phone you useing that good quality please don't say iPhone

[@davidhearne8501]

Hi Adam !. You changed the drill speed ? , what info do you use to know the different speed for the drill size ? Is there a rule ?

[@Abom79]

I have that stuff in my head from doing it long enough. Lathes only have so many speeds so I remember what size and what rpm selection to go with. But yes there are formulas to go by to figure speed, it depends on the SFM you need to run, and drill diameter. I have found that running a bit slower then recommended is better then burning up a drill bit.

[@orkidknog4147]

been waiting for another great video great thanks adam

[@RussZHC]

Adam: Seeing that stainless, with all your experience, have you found material(s) that are especially difficult to work with? Hard on tooling, refusing to chip, inconsistent quality, difficult to get a good finish etc. etc.

[@Abom79]

Yep, stainless, and aluminum bronze. I also dislike induction hardened rod stock.

[@Hyratel]

is the babbit from cut jobs like that recovered, or does it just go to the metallic trash pile?

[@Abom79]

Many cases yes it is but we have no need for it so we recycle it.

[@robertgiovannucci7144]

Good work, Adam! Holes were surprising close to outer wall. Any problems?

[@Abom79]

+Robert Giovannucci The new shaft should last a long time. I think they should have been inward a bit more though.

[@mikenixon9164]

Good video Adam

[@tylerclemens6089]

Sweet still shots at the beginning. Do you have the ability to true up an oldV8 truck head? I bet if you started doing that you would stay busy.

[@Abom79]

+Tyler Clemens We’ve always sent the engine work to the engine machines shops in town.

[@pandaward4671]

Did you ever get the flood coolant on the k&t working?

[@Abom79]

+Panda ward I never got back into n that project. One day....

[@capman911]

Do you ever put the metal shavings in a garden? I have heard that the metal rusting in the ground adds nutrients to the soil. This came from a man who worked in a brake shop and took home the metal shavings for his garden.

[@Abom79]

+Mark Harris Dad used to have buckets of cast iron chips he saved and they used them around trees and plants sometimes.

[@roderickwhitehead]

I woulda been worried about the bit walking at the bottom of the blind hole, but I guess you skipped the pilot drill for that part? Maybe I just wasn't paying attention in class tonight, though.

[@Abom79]

+R.C. Whitehead If you have the correct grind it’ll drill straight.

[@roderickwhitehead]

Abom79 - Roger that, Adam.

[@bjre.wa.8681]

Does the hole pattern get clocked and did the print give a coordinate table to set the holes by?

[@Abom79]

+bjr E. WA. I had a print to follow.

[@coldformer1]

clock the hole pattern ? no keyway wtf

[@bjre.wa.8681]

I should have said clocked with the opposite end holes, was all I meant
