Last weekend's efforts

Moving right along.
I have welded the pins that will hold the OTA struts on both mirror end, and spider end. I have cut the tubes, but (hopefully) they are too long, and I need to mount the primary mirror, and the spider/secondary mirror to testthe length of these tubes before cutting to final length.
I have made up a 27 point mirror support. (It is a Suchting mirror after all and deserves the best!)
The declination rotation will be on two rings supported by roller bearings and teflon brakes. I have made up the rings, the actual mounting position will be determined by over-all ballance. These will attach to the OTA struts (somehow)

Pics attached to show progress. They may explain better than I.
