I hope you are a very detailed patient oriented person. With lots of files and a dremel to go with that hand drill. I did mine on a cnc mill and it was a pain in the ass lol
My hats off to anyone who can pull off a nice looking one with just a hand drill.
Despite the jig advertisements on how easy it is, I can't imagine anyone completing an 80 they'd be proud of with just a hand drill. I suppose if you wanted something that functions but has a few errors, you could probably do it. I too welcome you to TGT, but can't help with the jig either.
