When building the torque tube up the ream the holes to interference fit ... Or
you will get movement .
There is an oversize limit to how big you can take the pins if you get it wrong
, but custom pins can be oversized (only up to that limit )to save your bacon,
any movement built in will increases in service .
300 +hours on reamed / custom pins and no play ....advice taken from Andy Draper
UK laa /one of the original Europa production engineers.

one of the torque tube clamping mods. I chose the one offered by Pat Tunney,
whose help and assistance was superb, but I think Bob Harrison has also designed
a very good mod. It was a swine of a job to do but I am really pleased with
the results and after 200 hours there is no sign of any movement.
