I had to modify the front swing arm brace to make it
something that I could easily make. In fact the modified part is simpler and
was easier to make than my original design. By making the brace tube a single
piece with a 192degree bend I was able to make more quickly and more accurately
than the previous 3 piece welded design. I call this piece a brace but actually
it’s main function is as the mount or actuator for the front shock. The swingarm
main tubes are easily beefy enough for the job especially since there will be
no braking forces (no front brake) and the lateral forces will be small
compared to a street bike that is designed to go around corners. Any lateral forces induced by turning or lean
angle will be due to coarse correction or cross wind compensation and should be
much smaller than what the forks of a street or track bike have to deal with.

The Bosch DWM 40L. Extremely useful for this kind of work. Far more accurate and versatile than a combination protractor square.
