I'm thinking you just have to drill with a bigger drill bit before (large enough for the head of the bolt), drill half-through, then change to a smaller bit the size of the rod and drill through.
I see. The challenge will be to fix them properly without washers then? (Nice pin job btw.)That style of pinning is without doubt the easiest of all pinning work, because after the initial finish where you've secured the pin all you have to do is basically file down the pinhead and work it to a smooth perfect finish, now getting two equal oval heads takes quite a bit more skill, here's some pinning work I finished on a Taylors 1000 a while back.
Cool. The look of the scales fit that razor perfectly.Mammoth ivory.
Very cool,1. Glue wedge to one scale.
2. Drill that wedge and scale with 0.086" drill.
3. Taper wedge.
4. Align and glue on second scale.
5. Drill through second scale with 0.086" bit.
6. Ream hole to 0.093"
7. Glue in 0.093" pin.
8. Finish pin flush with scales.
I think that's it. I hope it helps.
