Re:

Also decided to play with the forks. The intention is to firm up the feel on compression.

I've got a length of this elastomer rod, from China, rather affordable and fabricated
my own elastomer. Simply cut to match length then sharp drilled to create the
socket for the attachment above. Nice and slow to clear the material out.

This polymer behaves in stubborn way, firm but soft when cut, jams the blade!

Anyhow a 4mm bit did the job, smear of grease, in she pops.
I am doing one side at a time, incase of failure etc...one side will keep it all stable.

I can only trial this and see how it behaves/survives.
No idea of the shore rating etc...just tinkering for now.

nice work will be interesting to see now the diy elastima goes

Re:

Ok, just to update and draw a line under this.

It's all up and running. Rides smoothly, suspension aside. The front end was
re newed with new elastomers. More an experiment really with good results.
The elastomer is one equal length and easy to copy. I bought some more poly with a similar diameter. Improved the shocks giving a more responsive damp and upped the firmness to a heavy medium sort of feel. Job done.
Above all, I have plenty of elastomer for future maintenance. No search involved now. No cost either.
The rear shock....boing and more boing. Solution was easy, just robbed a spring from a supermarket bike or moto thingy. Being 1200lb the firmness is drastically improved for my weight anyhow. The shock gives as it should, when it should.
I could use this bike for almost any duty. Work especially.

nice to see the experiments
