Adjustable Rear Spring Seat
Posted: Tue Feb 12, 2019 10:00 am
The chap making adjustable spring seat conversions on my struts has come up with a novel suggestion.
1. Make a threaded sleeve (aircraft alloy) that fits over the damper tube.
2. Make it long enough so it rests on the alloy hub.
3. The bottom 2" (or so) of the sleeve is unthreaded.
4. Reinforce the lower spring seat with a threaded ring.
5. Drill 6 equidistant holes at the bottom of sleeve.
6. Adjust the spring height by turning the tube with a suitable C spanner.
Reasons for this arrrangement are -
When he took the original spring seats off they were not welded "square" to the tube. The threaded seat would be.
No welding of the sleeve to tube necessary.
Spring seat can turn as it is compressed.
I cannot think of an immediate objection, other than the spring load would be directly into the hub.
Would that matter? Any comments??
After that he can work on producing some proper adjustable rear wishbones!
