Re: [MedievalSawdust] Wood choices
- The best way I know of to get something to spin true is to fit the
bearings first, then mount it on the lathe using the bearings. Not
knowing the shape & type of bearings on the wheel in question, I
can't advise whether to leave any metal bearings in & use a 'dog' to
spin the piece, or knock them out after drilling & fitting & use the
regular centers then re-install the metal bits after turning to shape.
