A mini master class in work holding...Thanks Again Joe
You want a viral video?? Make one of these functional and cut some chips……I know you can do it!!!!
Worlds smallest functional Milling Machine! If anybody could pull it off it would be Joe. 👍😁
Hes gotta do it....he just has to...
Joe has to bolt it down to his mini machine shop floor and install a line shaft first!
A part made by using all the little machines would be cool.
Use them all to build micro machines.
I was impressed with the accuracy shown by the ability to get away with such a tiny T-slot cutter... but then you CHAMFERED it with ... what ... 0.002 chamfers? Joe P, you are a crazy man who is teaching me a different mental approach along with wonderful techniques and methods. Thank you.
Thank you for the drawing explanation, cemented the concept well as I understood it bassackwards.
"A drawing tells more than 1000 words." :)
24:00 perfection is not possible without perseverance.
No, no, Joe. Those aren't inclusions; they are premade apprentice marks for additional realism 😁
As far as terminology goes, you have inch-worms and millim-eaters.
I actually had a sweatshirt at one time with a picture of a dying centim-eater surrounded by cheering centimi. Its last word was "erg". Damn, i wish i could find that design again.
I like that. Thanks Paul.
More super precision work and, for sure, the knee is indeed butter smooth. Nice :)
:) It is now. Those added celcon washers and the bumper made it nearly silent.
Breakfast with Joe on the weekend. But Joe, that table is so easy to move. I had to move my shop gear to a new storage area. Moving a brown and sharpe table took two guys to lift it.
You have done a mill vise. How about a rotary table or dividing head feature for this project?
I thought for sure you were going to put it in the 4 jaw chuck on the lathe and center it on the boss on the end then run the boss round. After that make all the dimension from the boss center but you fooled me again and did it differently.
Ah breakfast with Joe. I can dig it!
I see you have the knack of wringing aluminium gauge blocks together..🤣 And those imperfections in the table top are called apprentice marks.
So many lessons in this video…thank you!!!!
Neat work--smallest tee nut I have seen ! Just a suggestion. When you are cutting with these very small cutters, we would get bored watching the whole job at the real speed, which is why you go to fast forward. But could show a few moments at REAL speed? I have broken a few cutters over the years before I learnt what that "real speed" was "real slow"! Thanks for sharing this with the whole world.
On the subject of terminology, as a watch/clock maker, I had to know watch parts in four languages--English, French, German AND American. Yes, there are several parts that have totally different names in US to UK .
Yipee 14 minutes & I got a Joe Pie video.
Thanks Koe.
Great.
I learn so much from your carefully thought through setups!
Thank you so much for your videos. You help and teach me. Again thanks urs from Switzerland.
My pleasure!
Great work,Joe.Thank you.
Another great video with helpful tips.
Excellent work, as always. A pleasure to to watch. 👍
As always it is a pleasure to watch you work your magic.
Thanks for sharing 👍
Been waiting a long time for the unloosening :-) Love your videos!
Thanks Joe
very good video Mr Joe Pie
Loved it as usual Joe.😎
Make it run joe! Bring it to life!
Awesome video Joe Thank You for giving us a detailed revision of your ideas and how you implemented them.
Amazing as always. Greetings from Mexico
Very nice and all see you when you come back Thanks for the Video
I think 45 minutes minimum for all future videos should be the norm from now on.
Awesome Joe, fantastic work as usual..
Hope those storms didn't cause any damage...that's some rain you guys got.
ATB....
Thank You !
Hi,
can you make a t-slot-mill out of a normal mill, if the web has the right size?
cheers
matthias
Absolutely. Surface grinder and a spin indexer would make it very easy to do that. In a pinch, a dremel tool and cutoff wheel could also work.
Very nice thanks for sharing
thx for the video.
I made a 1:20 scale model of the Northstar engine. It was perfect and actually worked, but after 20 minutes it overheated, leaked, then seized. Proof im the master model maker, so realistic.
I dont think i could have imagined a t slot nut that small😮but you made it possible at 1:12 scale so to imagine 1:87 is probably pulling a rabbit out the hat if not totally impossible. Guess i can jus dream on here lol. Amazing shop gems once again to handle such small scale work. Great video once again, thank you so much for these videos. It helped me understand milling and turning better😃
A tasty slice of pie.
Thanks.
Good day my friend. I reallly like the way that you see through physics needed to make these models work better than originly intended by the makers. You really do take them to the next step up. So far the castings have been really clean. Such a shame this has not been the case with this one. JB Weld has an epoxie I have used many times with great success. Inexpensive and tough stuff. This has gone by so fast I am going to watch it again. Many thanks my Texan friend. Did you ever try that waxy file treatement ? See you next round.
Greetings Sir. I did try it. Either I applied it wrong, or I'm missing something. It seemed the file didn't cut nearly as well afterwards with the compound in the teeth.
@@joepie221 Hmmm, I have only used it on files for silver and the jewlers saws I usually use it by filling the file litterally full of it . Oh well. I hope the rawhide works better for you old friend. Best soft jaws insert I have it glued to my vice jaws. That would be a bit on the extream side for you.
Beauty! ⭐🙂👍
You can! make a silk purse out of a pigs ear.Thank you for all the hard work in making these excellent videos.
Joseph, you usually use Delrin for your washers but this time you mentioned something different, what is it please?
Celcon. Acetal Copolymer. Delrin is a brand name, but they are about the same. Delrin has a much higher elasticity that plain celcon.
@@joepie221 Thank you!
Indeed, very small :)
Another excellent video, Joe! Would it be possible to fill the inclusions with some low-temp aluminum welding rod?
Bellzona!
Could you mill a recess for the top of the shaft (@2:50), to kinda act like a second bearing? Not that the shaft will ever experience much deflection, but if the shaft is going all that way up, it could a nice additional detail.
Einfach Super. Gruß aus Deutschland.
Maybe melt some lead in the table top casting porosity? Just a quick thought
👍Hey Joe, it looks like you move the quill after setting the Z precisely on top of the part? If so, how are you returning to that precise Z location again? Quill DRO or really good feel on the bump stops?🙂
Excellent work Joe. It's a shame about the porosity in the casting - I wouldn't be able to live with it and I guess you won't be able to too!
I'll figure it out.
Try some Lab-Metal!
CLIFFHANGER!!! AAAAGGRRRR!!!!!
Pattern makers down under allways call it taper .
Did you make that block with all the holes? Or do they sell them?454
7:30 commercially available 1-2-3 block, 33:00 that same 1-2-3 block used with a 6" mini tooling plate available here:

👍👍
What is the RPM for cutting the slot? I struggle with those little cutters!
1650 RPM +/-
Wow, thanks, I would be running wayyyy faster than that! Like full speed, 3500 RPM or more. Probably why I break everything! I have been using a feeds and speeds calculations which says 12000 rpm plus!
JB Weld Liquid Steel (Gray) will make those inclusions vanish.
Joe, is it me or did your mill get louder lately?
Wipe it off!
Looks to me like a t slot in the front will break through to the gap inside, or at least be much too close for comfort.
It will break into it.
Do you live next to a drag strip or something?
Any flat 6 mile stretch of highway in Texas is both. Especially if it originates at a red light. So Yes.
autocaptions seem to be broken on this video. fun video though, even with I not getting anything whatever you spoke :)
Some of the faster footage will not have captions or sound.
@@joepie221 I was talking about the section where you explains stuff. seems to work fine now. odd. you're awesome as usual.
Add a 1/12 DRO
That would be awesome.
Sorry Joe, but 5 minutes is not a long video, what? it wasn't 5 mins, sheez doesn't time fly when you're really engrossed in something awesome.
Great work and explanation as always, thanks Maestro. 👍👍
Did this channel change its name? I searched for Joe piezynski or something and only this one came up.
Yes. A while back I changed it to the name most of my subscribers associate me with.
If I'm this bummed on those inclusions I can't imagine how you're sleeping at night.
Solder would take care of those pits/inclusions
✋🏼🇦🇺👍🏼
It's good that you say about the draft and pin thing.........but you'd think it'd be common sense...
Good video
☹️🇬🇧
Common sense? I'm finding that particular trait to be a rare commodity nowadays. I see videos of COLLEGE students that cant do 3rd grade math (3x3x3. Etc) or cant tell you on what CONTINENT Brazil is found! (I realize intelligence and common sense aren't relative to one another) It seems far less people have common sense as when I was younger. (I'm 70 now) A lot of folks have the common sense of a rock...and some of those seem t ok have IQ's that could double as shoe sizes. You ARE right, though, Some things should be blatantly obvious.
It's looking great, Joe, but is it me or could a fifth grader with playground sand, charcoal grill, shop vac on reverse, and a bunch of beer cans make better castings than these?
Sounds good on paper, give it a go. Don’t be shocked when your castings turn out worse than these. It is an art in itself.
Investment(wax or foam) castings is the way to go for these small intricate parts.
@@grntitan1 I'm saying that crappy methods and an inexperienced child could do a better job than the manufacturer of this kit. The voids alone suggest that they're stingy with material and doing a bad job of temperature management.
@@ScottHilandI don’t disagree that the castings could be better.
Maybe for 1-off, but production run??? ⭐🙂👍
If you get it in, it will fall out...
The porosity of the castings is shameful and takes away from the excellent work you are achieving.
Thanks. I'll figure out how to fill them, but I would expect an invisible fix, or I'll really be bummed.
It's hard, no, impossible to give You full credit for Your master machine work, camera work and editing. You present just way too much to take in. Saving links to Your videos as reference? Possible but how to find the right one once it's needed?
Sorry Joe but quick looking here...
Thanks again!
Total waste of time. Download the model of a Bridgeport Milling machine and print it on your DMLS printer. Then whatever doesn't come out as precision as you like, machine those few parts. We're done casting. Hooray. More of my skills rendered obsolete
Serious or sarcastic?
I see you have the knack of wringing aluminium gauge blocks together..🤣 And those imperfections in the table top are called apprentice marks.
