It is common to simply grind a screwdriver to fit each screw... save them and grind to fit the next if needed.
That's what I ended up doing.
I "sacrificed" on of my Brownells wide "thin" bit, and used to Makita for the narrower screws.
All thing considered, it wasn't that bad. Gring-polish some... test... grind polish some more... test... repeat for the different screw width...
- Got wondering if I ought to anneal/temper them... But figure, I'd rather have something bend while applying force than "snap".
In case any one else is interested, Makita Slotted bits are a good starting point. As their flat sides line up with the bit.
On the up-side, I didn't mare anything
On the down side, couldn't figure out how to remove the action from the stock (I thought it was supposed to be able to just pull it out) to see why one of the firing pin doesn't retract when cocked... How well. I don't often get to wrench on boxlock. That was a fun way to spend a day in the garage.
- Project for this week, talk to someone familiar with Russian boxlock... Or at least try to find a part diagram
