The way he holds it for machining is BRILLIANT.Justsomedude wrote: ↑Tue Jan 09, 2024 5:57 pm Thanks for posting that. I'll have to watch it later when I get home. Tool and die makers are a different breed of machinist. I wish my dad would have done a project like that because everything he made looked like it belonged in a museum.
It's pretty cool because every now and again I'll work on someone's gun that worked with my dad and they tell me that he would have been proud of the work I do.
He is, by trade. And a lot of his paying work is on the surface grinder.Justsomedude wrote: ↑Wed Jan 10, 2024 2:19 am Dammit, thought he was a manual machinist. Not that there's anything wrong with CNC but it bores me.
That three-point frame fixture - bad ass! By the time he got to cutting those lugs off, there are plenty of anchor points in the fully machined opposite side to work from. Slick!Justsomedude wrote: ↑Wed Jan 10, 2024 3:33 am I've never worked on a surface grinder but I would have never thought that one would have the rigidity to act as a shaper. I've used my lathe to cut keyways the same way but damn does it take some time. I remember figuring out when I was younger that ingenious fixturing is what separates a machinist and a tool and die maker. That dudes fixtruing is top notch.
Maybe a Mauser action (or to satisfy my own selfish interest, an M1917 Enfield done up as an earless porter). While part of me is saying "Damn! That's cool!", another part of me is saying "All that NASA-grade work is wasted on a pistol"Justsomedude wrote: ↑Thu Jan 11, 2024 4:34 am One of these days I'll have to do the same but all manual, just to test myself.
That is what I do. Not the tool & die part (we have a tool and die shop though). The running/fixing/adjusting to spec part. My line has a blanker press that makes the lid out of a coil of aluminum. Each stroke makes two lids. Then it uses air to move them out of the die into a curler that curls the edges to be seamed to a can. Then they go through a compound liner that puts 55 grams (+-10) sealant in the curl. An oven cures the compound so it doesn't get on any of the next tooling. Next is the conversion press that forms the lid, adds lettering, makes a score where the lid tear upon opening, and attaches a tab. After a lid is completed it goes thru an air tester (big lazy susan with 30 pockets that clamp down on each lid and put 10# of air on top to see if any leaks thru). Last is the packing station where a packer puts 450 lids into a bag then put those on a skid.

The ones that cornfuse me is the can side. I hope I never have to go to that building. Most cans are rolled, welded and an end seamed on both ends. We have a salmon can draw redraw press that takes a flat piece of steel with a special coating on it and stretches it into an 8'' deep can with a bottom with no seams and the coating stays in place. It's like a fluid. The coating is very specific to salmon and can't be scratched in the tinyest or you risk botulism (?).
