I took an 18" length of thin walled brass tubing 11/32 in diameter (OD) and made a removal tool.
Clever, I like it
I took an 18" length of thin walled brass tubing 11/32 in diameter (OD) and made a removal tool.
Also, to set the proud nails, I used the round end of a ball pean hammer to seat the nail and smacked it with a 20 OZ masonry hammer with flat face.
I'd use a propane torch, at an angle.
Don't point it straight at the nail but perpendicular to it to try and just kiss the plastic to burn it / make it hard.
Interesting idea, that does create a nice smooth dimple in the wood instead of the hole you create by using a set. It's usually dangerous to strike two hammers together, but in this case it's safe because the ball peen is soft and the mason's hammer is tempered hard.
