Even though it was a bit windy and chilly, we had a good session on Saturday. Charlie, Craig, Jamie and Jay attended. Charlie laminated door skin to construction styrofoam which is the beginnings of a very light top ring for his telescope project. Jamie brought a 10" Celestron newtonian OTA which needs some parts to make a working telescope. We checked it over and found some sources for the parts he will need (spider, secondary holder and secondary as well as sundry small parts). He will need to build a rocker box and altitude bearings to complete the scope. It will be a nice 10" dobsonian when he is finished. I finished hogging out my 21" mirror using the diamond tool method I've described in the astronomy in utah forum. If you don't make it over to that forum, I can summarize that I hogged out the mirror in less than three hours altogether! This is a 21", f4 mirror so the sagitta is around 0.33" (in other words, that is a lot of glass to remove). This is way, way faster than I would have accomplished this task using more conventional means. Sorry John Dobson, glass removal is no longer caveman work!

Perhaps, but it is still very much "man-cave" work, lol! I didn't have time to make it over after getting my windshield installed, Mat. Hopefully next month. What are the parts Jamie needs besides secondary parts? I may have some on-hand. And what size MA secondary? On Mon, Mar 17, 2014 at 12:31 PM, Hutchings, Mat <mat.hutchings@siemens.com>wrote:

LOL Chuck, yep, I'd agree with the man-cave quip! Jamie mainly needs teflon, and ebony star (or equivalent) in addition to the spider/secondary parts. IIRC, the M.A. of the secondary was 2.3 inches. Jamie will see this post and can correct that if needed.

I have plenty of Teflon. Jamie, let me know how many square inches you need.

I've got loads of 1/4" thick virgin Teflon, can cut to suit and give the edges a 45-degree chamfer. Can also drill and countersink if needed. Just specify the sizes. 4 alt and 3 az, I assume? I prefer 1/4" to 1/8", it gives you more room to countersink screw heads. On Mon, Mar 17, 2014 at 1:11 PM, Hutchings, Mat <mat.hutchings@siemens.com>wrote:

Thank you gentlemen for you generous offer, I don't know yet how much I need, have not figured the base yet. The scope is the tube, and primary from a Celestron C10-NGT ( http://www.celestron.com/sports_outdoors/celestron-c10-ngt.html), Rough I.D. of tube is 11-1/8", thin metal tube. manufacture says is an f4.7 so we figured a 2.3" secondary. I was looking at Astrosystems for parts. it will be a month or two for the parts. Right now it's either telescope parts or tires for the car My wife seems to say tires for some reason.
