The shanks are to be roughened in line with the shank rather than around
DAMHIK
I am still re-gluing hammers from my first set that I roughened in a
circular fashion as the loosen in a school piano.

I made the desicion on my 2nd set to not use the glue that came with the
shanks, didn't care for it. I bored my hammers larger & used Franklins
moulding & trim glue, worked great!
