Hello,
working on my workbench project I stumbled over the dimensions of round bench dogs - 3/4 inch. Quite an unusual size for a metric person like me, but converted to metric this is 19.05 mm.
Getting a Forstner drill bit for 3/4 '' might be difficult in Germany, but 19 mm drill bits are readily available. My question: how much tolerance in diameter do the round bench dogs have? Is it possible to insert them in such a slightly smaller bore? To enlarge the holes might be difficult in a top with a thickness of 2 5/8 ''.
