Marking the parts.
Spot drilling.
Drilling under 1/2"
Reaming 1/2"+
Flip the parts and use a dowel pin to align the previously drilled holes.
Reamed halfway through, the other part is just drilled to 1/2"-13 tap drill.
Some other holes..
Slotting the parts.
I almost slotted into the one hole that doesn't need slotting...
But instead needs tapping.
Drilled and reamed 1/4" the end of some 1/2" all thread.
Facing some 1/2" diameter tubing.
Making a 1/4" shank, roll pin punch.
Small pilot on the end slips inside the roll pin.
In use pushing out a roll pin from a Sheridan forearm.
Hmmm. I suspected the end of the tube would do that. I'm not upset as you'll notice that the forearm already has a huge chunk out of it. I bought the Sheridan for $35.00 at a gun show. My plan is to make or replace the forearm.
I made a slip fit delrin pad for the end.
Just a slight pressure mark, I think I'll make a new pad from UHMW or other softer plastic.
The screw needs a handle but two nuts with a wrench work fine for now.
Adjustable...versatile...not a bad father's day project.
