What we've been doing this week
Swing arm set-up ready for tack weld. Getting each leg identical took a lot of (measure, check, measure again), I did a trial run first to get the process down, and this ended up to be within 1/16", so plenty good enough. One axle sleeve is threaded, and the other will be cut to add pinch bolts, allows use of the stock axle.
Had Fin do some test runs before welding the sleeve and making the splice. I used a bung to make the splice easier and to guarantee stength in the joining weld. Result turned out just dandy.
Set the swing are to accept a 19" wheel if I later decide to switch out the R1200R wheel. The symmetry end-up nuts on, so should be good to get started on the legs next.
Finished the pivot rough out, this will accept 3/4" heims. Tied a a few other option, bronze insert solid hiems and even a set of custom machined bushings, but the alloy steel heim seemed the best solution for affordability. The pivot brackets are asymmetric to give two trail option (or multiple with custom side plates.
Wow the upper tree did not want to budge, had to make some special tools to pull the pin out, and another special tool to remove the ball joints. Life is a breeze when you have the right tools. The upper tree bearing will be replaced with a self aligning one to allow the tree to follow the solid legs between upper and lower, but also the ball joinst become redundant to I will replace them with sleeves and M12 fasteners to ensure strength. i
