QCTH improvement lathe # 1 . Dec 2020.
Made an improvement to securing the quick change tool post. Machined down the original center bolt and cut a 10 mm thread then made an extension sleeve 93 mm long by 16 mm OD, bored out both ends and tapped 10 mm, also machined a flat spot in the center of the sleeve to take a 14 mm spanner, and tighten the sleeve to the center bolt. Then fit the QC tool post securing it with a M10 x 30 mm socket head cap screw, This is a improvement over the old M8 hex cap screw.
