Cheers.
Nice tyre, cannot quite see the size.

I do like wheels chaps!!

Ok, I have found some simplification that I think might work. I have bought Bearings that are I/D 5mm, O/D 16mm and width 6mm. I have also bought oilite bearings I/D 14mm, O/D 20mm and width 14mm. I shall ream the oilite I/D to accept the ball race. Packers will be used to make sure the bearing is where I want it. The oilite bearing will be filed and worked to look like the original bearing case. I will get the canopy posts made as per drawings/original.

The bearings have cost £30 a set. This way, there is a little more gap which is good to allow for movement.

Bearing drawings – need some simplification!!!

Yes Geoff, it is a double bearing race, that floats. The interesting thing is that there appears to be a collar within the I/D of the bearing, a la your bottom pic. I will print out drawings today,
