I did kind of mention it in "what have you got in the mail" but I have ordered enough silver rod and washers to do 10 razors and some pre made scales.

The cheap pre made scales are for my first attempt at pinning, I have a blade that needs something.

What is the easiest and most idiot proof way to figure out where to put the hinge hole and to make sure it's straight.

I have a little pin vice drill, it's very small and hand held.

Other than that it's a 1oz ball pein and a ful size DeWalt battery drill/screwdriver, no drill press of any kind.

When I get making the holes and pinning down pat I'll get some blanks and have a go at making some scales.
