Might be able to make a pocket in your existing fixtures to locate a punch and die from something that already exists, like a trumpf or amada press... Problem you might see with hole making is the slug may try to trap the punch in the die as well as alignment. But you could add guide rods and die springs to fix that... I would maybe have the punch portion lower, to punch only the hole first, then your forming die be further into your stroke because of your somewhat limited tonnage. The trumpf sized tooling is pretty small. I think it could be worth trying. Good luck, keep making videos.
Thanks, Tony. It sounds like you know quite a bit about this kind of thing. The Trumpf system looks pretty impressive. I am looking at making a new system with 4 guide rods instead of 2. The local stamp shop that gave me a quote on the work said that they would do the job in 2 operations, punching and forming They want $1600 for the setup. I have the forming dies already, I figured I would just make the punch dies. I wasn't really sure how to make the punching die that will make the center hole and the part shape at the same time. I was thinking I was going to have to do it in 3 operations. Maybe one die for the 5/16 center hole with a jig for different sizes of covers.
@@craigsmachineshop2040 trumpf dies and punches are cheap on eBay. Maybe $20-40 each. You'll also want some shims to get the punch flush with the bottom of your part. I worked for a precision sheet metal shop and learned a lot.
Hey Craig, glad you are back. You have taught me a bunch of things about small scale production. Don't be afraid of heat treating. You can do it with a torch for hardening and toaster oven for tempering. Lots of videos online. Your progress has helped me and probably lots of others.
Hey Craig - just so you know, ASU reopened the Techshop maker space in chandler, in case you need to use any of their machines, the have a couple mills (jet clone of Bridgeport) and lathes plus all the other normal metal and wood working. Although they don’t have the machine shop (mills and lathe) open yet, I think another week or so, I believe it will be $150 a month. They call it ASU innovation center I think. Good luck out there
Craig, have been watching your videos on the Tormach 770 setup. We just got one today in the shop where I work and will start setting it up tomorrow. Thanks for the great info. Funny thing is your shop is only about 3 miles from my house. Small world.
Good to see you back Craig. As far as pressing, could you maybe do more parts at one time than one with a larger press and make the time factor less of a factor?
Hey, thanks! I may try to do that with the hole punching. Maybe stacks of 4. Not sure that would work so well with the forming dies. I could try to set up multiple dies at once but I would have to have a large piece of steel to bridge multiple dies. Press brakes are great for something like that.
@@craigsmachineshop2040 Well I want to punch a 5 inch diameter circle, from reading the first few pages of a book on amazon I think I need like a 32 ton press unless I can bevel the edges of the punch/die.
Glad to see ya back Craig!
Thanks Jason! That Vulcan mill looks pretty cool. Would be nice to have 5 hp.
@@craigsmachineshop2040 ha ha...sure would. Keep up the vids..i always enjoy your stuff.

Thanks, Robert! Yeah, maybe I will have to give it a try.
From iraq well done
Great to see you again.
Thanks Roy!
This is great stuff Craig. You're opening my mind to what I can do with my Tormach. Thanks for bringing us along with you.
Thanks Greg! Nice, what Tormach do you have?
@@craigsmachineshop2040 I bought an 1100 with a tool changer. I'm having a blast with it so far.

Sweet! I might have to learn how to use the lathe. Thanks, Eric!

Oh and I wondered a bout using a log splitter hydraulic piston for pressing, it has a nice handle and is reasonably quick acting.
Log splitting, I will have to look into that.
Glad to see you back Craig, you might try p20 tool steel it's a pre hardened about 27 rc, so its plenty soft for machining but will hold up decently.
Thanks Daniel! Thanks for the tip, I will try it out. Not having to heat treat would be nice.

sweet, want to dabble in some punch dies after I finish up the current job
Nice! I am guessing that it isn't as difficult as I think.
