The session on 9/1 was a little more lightly attended than usual, but being the Labor Day weekend, that was not surprising. Daryl brought his 10" "Z" scope and this time added a 2" crayford focuser. That is a big improvement to the 1 1/4" R & P focuser it came with. He has made some real good improvements to this telescope. Daryl's plans for the scope next include either a fan system or an improved mirror cell. Charlie brought a 13" tile and plaster tool that he will use to grind the back flat on his 13" project. He will have to seal the plaster tool with polyurethane on the back and sides and I recommended that he melt paraffin wax into the tool from the tile side. This may keep the plaster waterproof enough that it will hold together long enough for the grinding. Jeff discussed ideas on how best to proceed with perfecting the polish and figure of the primary mirror from his 12" scope. He is ordering pitch, ceox, rouge, and dental stone from gotgrit. He plans on making the tool, pouring the pitch lap, and stripping the mirror coating prior to the next ATM session. That way he can use the machine to polish the mirror during the session. Which brings us to the next sessions. Here are dates that I am planning for the next several sessions (Saturday from 9:00AM to 2:00PM unless otherwise noted); 9/28 and 9/29 (another 2 day session. Fri starting at 6:00PM, Sat starting at 9:00AM) 11/3 12/1 12/29 1/26 2/23 3/30 Keep walking that barrel! Mat This message and any attachments are solely for the use of intended recipients.
