Re: Tasco 20TE's Rebirth [Re: mikey cee]       #3434539 - 11/07/09 11:50 AM Attachment (17 downloads) Edit   Reply   Quote Quick Reply   Egg trays from our old Hotpoint refridgerator make excellent temporary parts bins. Every screw, washer, nut and spacer will be removed and individually dipped in naval jelly and power brushed with a Dremel tool by hand. This is a very tedious and time consuming process. The only part not removed from the OTA was the rear mounting bracket from the front sliding tube weight. It's mounting nuts and washers were behind a glare stop that was too far down the tube to reach by hand. -------------------- 7x35 and 10x50 sears tower binocs, 3" f/10 edmunds reflector, 2.4" f/11.7 manon refractor, 6" f/8 jaegers refractor, "The 8 Ball" 8" f/13.3 brandt refractor, 3" f/15.8 sans&streiffe refractor, 3.1" f/15 selsi refractor(towa 339), 2.4" f/15 sears refractor, selsi 30x30mm spyglass, criterion 5-draw 25x45x75x spyglass(1957), 4.25" f/14.8 tasco 20te.
