Hi Glen,
Sounds like you made an initial fit pretty well, but then you put on the
clamp and tightened it!
How I've conquered this one is to oil all surfaces of the clamp, flange,
pipe, on both sides of everything prior to fitting the clamp and tightening
it. You need the clamp to slip on the pipe as you tighten it instead of
pinching it and getting a couple of puckers on the -uckers as you tighten it
up!
Yes it gets sort of slippery handling it but if you tack weld the bolt head
to the washer and the washer to a clamp half, you have a whole bunch less
stuff to wrestle with as you curse the design while fitting it up!!
Later, Paul A
