Ordered an Aeropack motor retainer for my 38mm f/g Lil Goblin. Also disassembled my Dremel and removed the disintegrated coupling that prevented the tools from spinning. The replacement coupling should be delivered tomorrow. Amazon stocks the complete line of Dremel replacement parts should anyone be in need. Discovered that 91% isopropyl alcohol will remove black magic marker ink from fiberglass tubing. I use it to mark cut lines, etc. Silver markers are Crazy Jim's recco for marking black fiberglass tubing. Works!
