WANTED BUSTED, BROKEN, RUN DOWN, CRACKED, STUFFED angle grinder
If you have a BUSTED, BROKEN, RUN DOWN, CRACKED, STUFFED angle grinder, I'll take it off your hands. Why you might ask, because I will take it apart and use the two right angle rotating axis and its gears for micro adjustment on a telescope mount I am building. The gear assembly will go in the pier and attached to the shaft to rotate the telescope mount in azimuth adjustment by hand. All this is needed to achieve what is know as polar alignment of the telescope mount. You can follow the build of this telescope mount at 'Warrnambool Astronomy Nights' Facebook page. Thank you.
