evenin all... its really not all that difficult to do. I started with PSI's Big Ben Rollerball kit. The cap portion is turned as per the instructions..no real changes there. The lower barrell is turned using some spacers and the bushing for that end of the blank. The tail stock is used for support. After turning just about to the bushin, I switched over to the pin chuck for the Baron kit. 10 mm is a little bit larger than the Baron's 25/64 tube but the chuck held it securely enough. Really about the only thing I did on the pin chuck was the final shaping, sanding and finishing. i don't care for the threads on this kit so wanted a way to get around having to use them. Glad you guys like it....you should try it. Almost as much fun as a baron!
