I wouldn't claim that my humour is English, just my own brand of fun and comedy.

I thunk the f2 forks are held together with circlips so different kit required . I don't remember the o rings being present on a set I had and serviced, but I could be wrong as it was a few years ago now. I do have some f2 spares somewhere.

late to the game, but yes. F2 forks use circlips and has no o-rings, while the F3 uses the domed screws and o-rings. Brion told me you can forgo the o-rings if you keep the fork relatively clean. if you are rebuilding an F2 fork, I've found circlips and the nylon washers easily at a hardware store.

I used just standard o rings that i got from lidl in a multipack type box. All its doing is sitting against the pivot, tbh i dont really think it stops anything :?

OK had the day to myself , and striped the AMP F3 forks down , and yes it's ALL English , so yes you can change the shafts ,which are 5/16" to take an M6 screw BUT the i can not find English top hat bushes or 0.080" & 0.090" plastic washers ( although i can make these ) the plain bushes are still available as the O rings are all of the shelf , any body got any ideas ? Happy New Year

Bad day on the AMP fork front , striped one of the alu 1/4" unf screws , so not being able to find any 1/4"unf screws ,i am going to try to replace the pivot shaft with a new one machined from Silver Steel with M6 screws and if its not to much of a pain i will replace all pivots this way , the pivot will be drilled all the way through , as original with stainless steel flanged domed screws ( hope to drill these out too ) any body else . :!:

Sounds like a very good idea. Im really glad we decided to change the pivots and spring collars to a modern super hard alloy. Good sense in the long run and anyway :? Who is to say the original design was perfect

Maybe about weight back then but given theyre pretty lightweight anyway a few remade parts in steel would probably not add that much. More about longevity now

"Im really glad we decided to change the pivots and spring collars to a modern super hard alloy."
confused , one with the " WE" , is that the royal we , and two super "MODERN SUPER HARD ALLOY"
if you mean silver steel ,this will only be in it's normal state , not heat treated ( could get too brittle )
am i making just a set for me or do WE need a set :?:
