Painted the reel today. Hopefully most of the Hammertone green will go on tomorrow. I won't get to the chassis for a while as I can't get the welding done until next week.
As for the front rollers, OD is 70mm and thickness is 1.6mm Tubes for 20" are 493mm in length. Tubes for 17" are 417mm in length. I belive tubes for 14" 337mm (TBC). The 6m of tubing cost just over $80 from Stirlings Australia. I just had them cut it into 2m lengths so that they could fit in the car.
I still don't have a solution for the fibre washer to go with the brass thrust pad. Any ideas?
