I've got to do the final tightening of some cylinder heads tomorrow.
I've been using a torque multiplier but for some of the bolts there's
no good way to secure the reaction arm & it's been getting damaged.
(it's the type designed for waggon wheel nuts which uses a second
socket on another nut)
My big torque wrench has lost the 3/4" square shaft which connects it
to the sockets, they're a special order item so I can't just buy one
off the shelf tomorrow.
If I square up a piece of mild steel bar, will it take the 500 lb-ft
torque, or just twist off? I could find a bit of stainless or EN8 if
that would do better.
I would just try it & see if the job was here, but it's 30 miles away,
it must be finished tomorrow, & I'd struggle to find something here to
test it on. OK, I could weld a big nut to the side of a boat on the
dry-dock and use that, but we've just finished painting it and the
owner is coming to collect tomorrow!
