I've got the toeplate patchbox from MBS, but the knuckle spacing is such that it'l look bad and not leave enough material on the outer knuckles when trimmed to fit the narrow SMR.
Read the great tutorial on bending hinges by Acer Saccharum here:
https://americanlongrifles.org/forum/index.php?topic=22371.0The tool he made looked really handy. While I could make something like this out of metal, filing would take forever, and my CNC router would make a mess (I really need to run coolant when cutting steel). Thought about wood, but figured it'd split out way too easy. Since plastic worked last time, thought I might try it again.
I decided to try a two stage approach. Wasn't sure if a small lip would break or not. This is PLA plastic. It's the cheapest and easiest stuff to 3D print. Quite strong, but not very heat resistant. Cost about 60 cents to make.
Hammered the metal flat over the edge of the vice first, then put the bigger former in place.
Pried up with a screwdriver a bit, then hammered to 90ish.
Swapped out the big former for the small lip version, and hammered the rest of the way over.
It worked very well. A piece of the 1/16 wire that comes with the Kibler kit for pinning stuff together dropped right in.
Was surprisingly easy to hammer it cleanly around the wire.
Now, this material is thinner than I plan to use (it's 22 gauge - .030"), but I'm still impressed by how easy it was. It probably only took me 5 minutes to make, and I've never tried to do a hinge before.
If the thicker material works this well when it gets here, I'll be very happy.
