|: I put a block of wood in a vice sticking up, jam the boots onto it and drill straight down.
: Also I use a small rectangular shim of metal with holes drilled either end as a washer for the front mount bolts on the inside of the boot. Also helps stop the bolts pulling through.
I still don't quite get how and where you jam the boots between the block of wood and the vice, can you expand on that?
Drilling straight down is hard with a handdrill.
Good idea on using rectangular shims! It might just be that I used the exact same kind of shims on my self-made soap shoes. I'll post some pics of these later on, when my skates are finished and my room is a tad tidier.
