Graham=2C


I fully understand=2C but one would check before installation that the tube
s slide easily over the torque tube.

I did have the swarf problem on one side early in the build because I did n
ot use a brand new drill bit. It was quite a job to fix that with a special
 homemade abrasive tool.

I think there must be a simple way for new builders to drill the pip pin ho
les BEFORE installing a single tube.
