My problem now is mounting the Dave Brown spinner that I boughht with the plane (on a DA 50).
There is no bolt to attach the spinner cone. The drive shaft is tapped for a M5 bolt, so I need about a 60mm M5 bolt.
However, the opening at the tip of the spinner is too small for a M5 bolt, so do I drill it out? Am I missing an adaptor?
M5 is interchangeable with 10-32. There are two ways to solve the problem.
The slick way is to use a 10-32 socket head (allen) bolt, they are available at any hardware store. That will fit in the spinner with no changes.
The cheap way is to just use a 10-32 phillips or slotted head. IF you have a belt sander or gridnig wheel hold the side of the head against the abrasive and twirl it in your fingers, the OD will reduce evenly. Take it down until it fits in the hole in the nose.
If you don't have a wheel or belt sander use plan A.
