You can't use taper pins, they will distort the tube and that will cause
friction in the bearings.
Only alternative I can think of is expandinhg pins. You will have to make
your own. I made a set from the soft 1/4"stainless the factory use, taper
hole in the ends and taper bushes to expand the tube by tightening AN3
bolts.Worked beautifully. Don't think PFA have approved this soloution but
I did write to Francis years ago.
