How thick was the steel plate on your apprenticeship course? What dia
for the centre bolt? M12 is about all I can find around here.

Something like 4 or 6mm I'd guess, just whatever off-cut was lying
around the workshop at the time.

Apologies for the dropbox link but you can close the sign-up window to

I welded the centre nut to the plate as trying to get a spanner in on a
3 bolt pull was a pain but on a 2 bolt it should be fine although I
could have threaded the plate instead, must have over-drilled the hole
by mistake.



By the way, did you still have to whack the centre bolt after
tightening it?
