Default Washers and cups.

I have been experimenting lately with small OD 3/8 bore plastic washers on my DA45s. Two issues cropped up and one good benefit. With the small OD washers, I had less ramp up of resistance during deep pushes. The trade off is cushion life on the left front truck. If my kingpin's smooth shoulder(non-threaded area) was longer and I used tube spacers to keep the threads away from the cushions, that problem most likely would go away.
I cut some plastic washer down(3/8) with an od that matched the tapered lower cushion small end, then cut a 45 degree bevel on the edge. Installed these before the session today, then ran them for the full session. Results are that the wider washers, no cups, would still ramp up resistance at the end of the stroke on low fast skating. This promoted traction loss with wheels and suspension that had previously been working well.
So more work is in store to find a happy medium. Maybe a new style washer is in order that lets the cushions give without damaging them. Got to make several changes and try to keep low ramp up and retain cushion life and also not have the cushions/washers hit the trucks during extreme truck turning angles.
