Home Forums Hunting & Shooting Gunsmithing Stock duplicating and bondo to shape custom stock

Bondo is the pattern makers friend. Forget Urethane, a waste of time.

After I have the pattern and bondo shaped I spray the whole works with a hard setting black epoxy for a smooth surface for the tracer. Works like a champ.

On the stock below I am extending the pistol grip. There is a piece of 3/4 inch thick oak under the bondo, screwed to the stock. Build up your thick areas with wood for a good structural support, then fair in with bondo. Thick gobs of bondo will fracture.





Regarding pressure, on my machine, the operator is completely in control of the pressure applied via the two handle bars shown in the below photo.
