Manitou 4 Fork help??

[syncrosfan]

I'm already planning to make replicas of the Westpine hubs (impossible to find), maybe have a go at a set of Onza Ti cranks?
But right now I have way too many bike projects running at the same time.
I would love to get a small CNC mill and make my own parts whenever I feel like it...

This one is 1.5" but will the ID & OD suit?

and I can get them here for small change.

Watch those imperial measurements! This is roughly similar to what I have: http://www.centuryspring.com/Store/item ... mber=11575

Actually that site is pretty useful to figure our what spring rate I've got: 40lb/in spring x 2 = 16kg/cm fork travel.

None at that hardware store look ideal, except maybe 2 of these in series: http://www.bunnings.com.au/century-spri ... -_p3970468

Anyway, all good fun tinkering and experiment with in your spare time

Picked this up earlier this week:

It's in really nice shape - ad said "for parts" but other than the red elastomers being a mess, the two firm yellows in each side look and feel fine. Lowers slide on the stanchions as smooth as butter. 5 minutes with a water blaster and an air gun and she was all clean and ready to go. Odd that the red ones melted and the yellow ones didn't....?

The elastomer stack from a later Mach 5 fit right into the Manitou 4 - even though the Mach 5 doesn't use a skewer, the elastomers have the skewer hole in them already - and they are exactly twice as long, so uses 3 instead of six. Overall stack is 16cm. So if you find an old unloved Mach 5 (they aren't worth squat), you can reuse the innards.

Got this as a backup, but it's super cool and super simple.
