Guma Richard, in East Africa Uganda am impressed, given the fact that with in 2 days am receiving a vertical/horizontal milling machine!Thanks so much 😀

[@daleburrell6273]

...well, how are you doing-(?)

[@David-hm9ic]

OMG! The chips at 33:00 are GORGEOUS. They look like Colt's charcoal bluing! "Gonna let t his cool." I learned that lesson with stainless the hard way recently.

[@akfarmboy49]

35 years ago I worked in a small shop in Minnesota. They bought a new Morrison key way cutting machine and I remember those bolt in inserts

[@araofmadisoncasey4247]

thanks for the variety of view points on the camera

Today, I had to broch a 1" keyways in (2) 3-13/16" couplings using a Davis/Hanford #5 Keyway machine ...it chatter...I bartered the Davis machine for a repair on a Bullard broken lead screw and casting some 50 years ago...(The truck driver took out a railroad bridge with it)...I was cutting large keyways on my shaper before I got the Davis...Now you got me thinking of a vertical shaper...I see that it's a better way to cut keyway as well as other things (I.E. splines) and cheaper too. You did a good job on the holder....A new 1" broach for the Davis is about $700.00 You can buy a lot of Morrison cutters for that...I use Endmill holders for holding endmills in my Bridgeport's.... I avoid collets ...Endmills get "SUCKED" out of them...Ever seen a Bridgeport table with progressive blemish in the table? ...A small piece lead to seat work in the vise. Somebody taught you well to use you hand to clean the vise..."Your hand is the best cleaning cloth" Just don't get hurt!......Robbie

Josh, the video was perfect. Good focus, great lighting, cut-scenes, good sound. Excellent!! Congrats! And, great content, of course! Thank you for making and sharing the videos!!! Greetings from Belgium.

[@scottthomas5999]

Nice job.

[@TradeWorks_Construction]

Really enjoyed the multiple angle shots, not many makers take the time to film the cuts from many different positions. What I appreciated more than anything was the time you took to really document the close up work so we could see exactly what you see while working. Without those close ups we wouldn’t really understand what you’re chasing after in the cleanup passes. Compared to other channels I like your practical approach to machining. It’s a business so it has to get done and only as precise as is required for it’s needed purpose. Like you wouldn’t fuss about a thousands here or there on farm equipment but here where the tolerance is literally +\- 0.001” taking the extra steps needed becomes important.

[@ericmcrae7758]

I am sure that tool will be added to your "Treasure Box". When I was an apprentice we made our own tools always give a sense of satisfaction.

[@shaolinshaotse]

Beautiful work, great video as always! I can never thank you guys enough for the film-making time that you dedicate to sharing and teaching and entertaining us 🙏🏽🙏🏽 Especially your videos with all the extra little insert shots and coverage angles you give us, it must double the time! One quick thing I do to create those corner reliefs is bring the small cutter to the edge numbers, step over and up 10thou, and just plunge down to depth. Thanks for everything Josh!

[@TopperMachineLLC]

Thank you. It is a lot of work, but I think it's worth the effort.

[@tced2858]

I always enjoy your videos Josh, now it's time to "Get out in my shop, and get it done right, the first time"

[@BruceBoschek]

Your video quality is absolutely top! Thank you for taking the time and making the effort to do all of that video setup. Shop-made tools are pure gold. Looking forward to seeing the More in action!

[@bostedtap8399]

Great build, always nice to make your own tools, that are better than bought, " Built not Bought". Brilliant job on videoing, fantastic close up on milling shots. Thanks for sharing.

[@curtisbahr9747]

Very nice job. I really enjoy your videos that have hardcore machining in them, I learn something from each one. Video editing is most excellent.

[@arthurjennings5202]

It's nice to be able to make your own tools. Wait a minute. You are a tool maker.

[@BrucePierson]

Really great having the machines to make the tool to do the job. Saves spending a fortune to buy the tool, it it's even available for your exact needs.

[@TopperMachineLLC]

I wind up building a lot of stuff. But with this machine, nothing exists. Everything has been made, and more is needed. One job at a time.

[@RalfyCustoms]

Great stuff Josh, always enjoy some tool making buddy, thanks for sharing 👍

[@craigtate5930]

what a great addition to the shop. I hadn't been paying attention for some time, didn't know you had gotten a slotter

[@TopperMachineLLC]

I've had it since before I started my channel. I have done a few videos with it.

[@stevenjefferson3379]

Josh, on squaring those corners with a small end mill I peck drill down to clear the chips then once I reach the desired depth I walk the end out x and y. This eliminates the chip build up and most of the lateral pressure on the small end mill.

[@TopperMachineLLC]

I thought about doing that. But it was more dramatic seeing the breakage and deflection. Entertainment value. Lol.

[@stevenjefferson3379]

You were thinking way ahead of me! Thanks again for a great KZbin channel!

[@basbh1782]

Steven exactly how we did it back in the day

[@M1KEMEX]

You can mill the corner pockets with a tiny mill if you feed it vertically as if was a drill bit. Two flute mills were called slot drills for that reason. Any mill with center cut can do that.

[@ralphjaneheywood2565]

Hi Josh, I made a similar tooling, I stoned a small radius on the the back corners of the cutters. Kai ora from New Zealandi

[@ellieprice363]

Good job machining that heavy duty very versatile tool. Can’t wait to see that big boy doing it’s stuff.

[@DavidHerscher]

I would have tried plunging with that 1/8” endmill. Touch off on the side of the slot, move over the radius of the cutter, so .0625 ~ish, and plunge. Boppity boopity, no schmoopity. Love your vids.

[@grahamsengineering.2532]

Hey Josh those indexible end mills are very good, I use them all the time. I need to make some of thes bars for my Slotter but will be using HSS as it's cheap and I have an abundance of it in varying sizes. In Australia those slotter inserts are very expensive.

[@TopperMachineLLC]

I've made a few for HSS, but these larger sizes are better to use these inserts.

[@terrycannon570]

Excellent job. Thanks Josh

[@RixtronixLAB]

[@kentuckytrapper780]

Great video Josh, I use some shars tooling haven't had any problems with it, we do with what we got sometimes, excellent job.

[@alanm3438]

Good job on the video and the project. Even though I am not a machinist, it is interesting to watch you. I failed on my one project so I decided to make a pig out of a car spring. I already had the programs made for the pig parts when I turned a helium tank into a pig. I need to paint it but he looks ok. The small garage that I got the springs from wants me to make a few up and he wants to try and sell them.

Instead of using a small end mill in those corners, you could just drill holes in the corners.

[@leopold7148]

Awesome video Josh! That's one beautifull tool you've got there.

[@hwen9483]

Where do you get the key seat cutter from?

[@ronwilken5219]

Hi Josh, great improvement in audio and presentation over some of your earlier attempts. Well done and thank you. One question or suggestion, but when you tried to square off the corners with the 1/16" cutter would it be better to mill it vertically first. That way you would, or should, experience less deflection. Just a thought. Thanks for the video and as someone else suggested "better built than bought ". Regards from Canada's banana belt. 🤞🇨🇦🍌🥋🇺🇦🕊️🇺🇲👍

[@hobtink]

Do you need to have some space in the slot to account for the expansion the cutting head is/may experience due to heat up during use?

[@jorgem-oy4ys]

Hi, can you inform the name of the custom made supplier for the insert?

[@brian_2040]

Hey Josh, ive heard you mention before that you are in the middle of nowhere, just wanted to know if you are out like that, are shops a big demand? Kinda wondering if you have competition, what do they do? Just getting a idea of the area. Kenna metal is big around here, but thats for asphalt planers, and reclaimers, and bucket teeth. I know that is different from what you use.

[@TopperMachineLLC]

I plan to do a video on these exact questions. Basically, I am in the most economically depressed region of the US. There isn't much industry left and I have zero competition.

[@mhibe]

Hi bro can you help how to get cutting Knife in mm size

[@M_Northstar]

Very interesting. Two questions: 1) Why was that part scrapped? It seemed perfectly symmetrical except for the holes, so couldn't one plug those up and recut them elsewhere on the cylinder? Or would that just not be worth the effort? 2) How long do those carbide inserts (from the last, tapered, operation) last, and what happens to them after all points are used up? Are they ever reground, or are they thrown away? Thanks as always for an excellent video.

[@TopperMachineLLC]

Part was scrapped due to the width of the keyway being .003 too wide. That was the only problem with the part. The inserts get recycled,. I sell them as scrap carbide.

[@ericmiller5559]

Excellent content, thanks for sharing. Although pretty soon you will be able to remove the rubber mats and just walk on the chips LOL. Just kidding. But you really could use some house cleaning the shop is kinda messy with all those chips on the floor and machines makes it look like one of those sweatshops in India.

[@TopperMachineLLC]

I could use a helper. Been so crazy busy here I can't even stop to think.

[@ericmiller5559]

@@TopperMachineLLC If I was in the area I'd come to be your helper. Maybe the local junior college has somebody taking shop classes that might be interested in helping offer them some instruction and machine time as trade. Keep moving forward.

[@davidc538]

that cutting oil looks like honey mustard

[@alanpecherer5705]

Not a machinist, but in trying to square off the corners of the pocket in which the slotter bit sits (which is impossible) wouldn't you be better off drilling (or plunge milling) out the corners and machining a flat across the narrow dimension of that pocket (which you are doing anyway with the small cutters) and using that as your rear support for the bit? It seems to me the absolute length of the pocket is not that critical as you'll adjust the throw of the cutter with the dials on the machine. Excellent video!

[@the_real_randall]

How tall are you? Just curious because I am pretty tall and I hate bending over in front of a mill and wondering if I went with a bridgeport style mill if I would want to raise it a bit. Sorry in advance for the personal question. Really enjoy your videos and maybe I am too concerned with ergonomics.

[@madaxe79]

Let me offer you a little advice on those tricky corners.... mill the flat first, before the slot... then drill the corners with a regular drill... then do the slot, and you only need to clean up a tiny little corner... save yourself the trouble.

[@termlimit]

Excellent video as always. What rpm did you run that shars indexable cutter at to cut the slot at the end of the bar? Thank you for your time!

[@TopperMachineLLC]

Same as the other cutter. 1115 rpm

Don't know why you have such problems getting a tooling rep. to visit, all you have to do is buy $200k/yr of tooling and they will visit AND bring coffee and bagels. :-) Keep up the great work, "small" shops like yours are where companies turn when one-off or must-have-today items are needed. I know cause' I work for such a company. Don't be shy about charging a rate to allow you to stay in business. When a production machine goes down, we lose thousands a day. We look at not the cost of the part but lost profit of being idle. Beyond the daily profit lost for a down machine, failing to meet a delivery date could lose a customer.
