Upper Support Assembly (USA) Finished!

[COLOR="Purple"]Hi All!
It's taken a while but I think the USA for the 18.75" ATM project is done. When last I posted, I had added a second ring to the single, too floppy, original ring. That gave me a stiff enough structure to hang the focuser board off of. I was then trying to figure out how to improve the support for the focuser board. Here's the result in several pics. 1st is an overall view.

Hello:
That looks very nice. How much does it weigh? For my 17.5", I'm going to try to keep the top end weight below 4.5 lbs (without eyepiece). I noticed that you have the Kineoptics helical focuser. How do you like it? Have you had a chance to use one? I am tempted to get one since they're so light, but I'm skeptical as to how well that design will handle heavy "hand grenade" eyepieces.

Cheers
