On the “fast & furious” series, I had some nice time with the parents at our countryside home, and grabbed a mahogany cutoff in one of them bins, cut it to size and brought it back home (along with some goodies for someone here that will recognize himself ;)
Just attached it to the pen lathe (drill press helped drill and countersink the holes), the previous part was a crappy plywood chunk which edge was quite worn off, resulting in less than linear motion for the chisels! This will help things a lot. Next up, add a circlip to the mandrel to avoid lateral movement and vibrations!
