Brit your idea for making some brass spuds is a good one, but how will you stop the optics head from slipping round? I've been thinking of adding a counter balance weight to mine.
Interesting spelling option - I was taught that optical alignment tools were collimators - I'd not seen collimeter before, is it a trade name?
