Slick design. You probably already know this but sites like Mcmaster sell flanged brass bushings in many standard sizes. Combined with shoulder bolts this is an easy way to accomplish the smooth pivots as in your design minus the lathe time. Another slick design trick is making small cylindrical bosses where the bolts clamp up. Throw a fillet or some draft on these and they spread the clamp force wider into the part yet. Common on ductile iron castings for heavy trucks.
A great technique! That's what I do with buffer threads, extend the corner away from the interfacing part to prevent interference. Unfortunately there is just not much room on the little levers.
3D printing tools and tooling is legitimately one of the best uses of the technology possible. These can be rough and don't need to be "distribution ready" so long as they help out on the shop floor.
Late to the party on this, but good on you for recognizing the limitations of 3D printing, Hoffman. There's just some things that, no matter how hard you try, you cannot do with plastic. And in many cases, there are things that you can do, but are simply better off doing with metal anyway. I wish the 3D printing fun community would embrace using the tech to solve problems it can best solve, rather than feed into this wildly overgrown "not invented here" syndrome its been nurturing.
Hmmm Interesting video always open to learning material I never heard of or thought about. Thank you for sharing and looking forward towards filament strength reviews.
You can add features into your CAD to force a sharp internal corner on a print. Just be sure to turn off Arachne in your slicer or it will ruin your hard work.
@@darktrojan00 nahh it would take so much work and redesign to use that press it would be much simpler to just use buttons. It would be easier and a higher quality product in every way. With a single cutter you'd have to get your spiral from the up and down function and repeatability would be an issue and so would wear, tool sideload and tolerance. You might take 10 thousands off the sidewall but it would be accompanied by 30thou on the machine. Definitely possible if upscaled by about 350% but then printing would be the problem. This is one of those jobs perfect for using a 3dprint to make a metal casting.
Hex is easier to find around the house (Allen key), which is why I went with it. For the custom shafting I think you are correct, but it would add some complication having several types.
Please make a 3d BULLPUP LOWER FOR ar-15 UPPERS that use 3.5 inch buffer tubes. The 3.5 inch tube to keep standard size, reliable, and upgradeable bolt carrier groups and compatibility with certain kinds of triggers 👀. The 3d BPAR-15 with its 3.5in buffer incorperation and the (unreleased) 3d FM15 bullpup lower has figured out a forward mag release. Those are close to an "end product" but this concept needs a professional like you to be able to trust the design for serious use consideration. Your ar15 designs are proven, I think people would want an ar15 bullpup evolution they can trust.

Thanks for researching filaments. The improvements are anticipated greatly.
I have no idea what this is about, but that just makes me appreciate what you're doing more. Grug like smart man protecting liberty.
U really have no guess what that press could be for? It's obviously for a heat insert press

@@AckzaTV a broaching press is different than a heat insert press.

I need a reason to use my lathe ;)
hell ya I love square and hexagonal holes without needing the wire edm at work, I'm all about this
Based edm enjoyer.
@@armorers_wrench or just imagine having to grind a carbon electrode, juice it with AC, and stab your workpiece into submission like a caveman lol
Intriguing! 3d printing as a prerequisite step for more manufacturing.
I think the way you set up your production lines is superb. Good luck on your project.
you could also modify the geometry of the hex cutout to be more of a 6 point star shape to compensate for the printer's tendency to round off edges

Always great to see what ya create Hoff.
Great video 👍
Your technical explanations are entertaining and educational.
Thanks for sharing.🇺🇸
Good vid as always. Keep up the good work. Love your designs.
i appreaciate your apBroach to this problem.
Always on another level, bro!
i just wanna say god bless you man! i wish you the best. The SS concept changed the world and lives ! THOU SHALL NOT INFRINGE
Cool stuff thanks for the great service and effort you put into this keep the info flowing 💪

GD this young man is exceptionally smart!!!
Great attention to detail!
Tim is an absolute G.
Always great videos man keep up the great work.
Adapt, overcome and broach some parts
Bro are you some kind of secret scientist?
A great project
Could you recommend a video or something to get that level of bed adhesion? If I tried to do that print it would curl up like a leaf spring.
What is this for? I can’t tell what the little piece being drilled into is.
Any plans for a 308 Orca? Also PLEASE TEST PPS
Yes.
love you Hoffman!!!
re: your last comment about testing materials... have you done any extensive testing with SLA resins yet? Some of them look promising.

I'm so confused, this a new 9 called the broach??
Brother I'd love to see you test that new electrolysis metal print stuff or try that rifling print
Nice job!
Are there any plans to convert this press into a reloading press?
I know that shirt!
nice!
Hoff challenge produces the M41A-Pulse rifle with a flamethrower., and rocket launcher if you can?
Y ooo, Hoff, long-time no-show, welcome back to grid bragh. Like always, it's disappointing, but it's an impeccable educational video!
What lathe do you have?
Now make a contraption to make barrel rifling
My first thought. You could probably use this if you had a series of progressively larger rifling buttons
@@noahmcabee2534 well it could be as easy as a spiral shaft and a single cutter essentially cutting every groove

Oyyyy gavalt!
When sequential
undersize the holes and then heat stake the hex shaft into them. cant get any tighter than that.
True, but then we go back to the issues with complex / difficult assembly.

3dp easy jig for optics cut
You would be better off going to square.. It's less likely to have slippage.
