sinclair handwheel info needed

[AusFclass]

hi guys!

im working on a bit of a project and am wondering if somone can help me out with info on a sinclair handwheel (the ones they sell for adjusting vertical on front rests).

what is the approximate diameter of the wheel including the 'spokes'?

can the 'spokes' be unscrewed or removed easily?

6-3/32" across the spokes (15.5 cm) and no, the spokes aren't easily removed if the current product is anything like the one on my rest, purchased about 7 years ago.

They 'might' be screwed in, but I wasn't about to break out the propane torch to heat mine up! a 7" visegrip wasn't sufficient to get one of the spokes to loosen, if they're threaded & not pressed / Loc-tited in place.
