Kevin, I made one – but the football needle was a) only just long enough to reach into the top of the fork leg, and b) too flimsy, as I twisted it to pieces in the end, (leaving a few frantic minutes of swearing and fiddling with needle nosed pliers to extract the stubby end from the fork leg!). Getting one turned up on a lathe would be the better solution, though far more costly.
As I found by trial/error that the best ‘feel’ was with no pressure in the IFP chamber, I could have just let the pressure out using a fine allen key (there’s what feels like a ball bearing with a spring behind it making the seal – depress it and the air comes out) and not gone to the trouble of bodging a tool up. Stick a rag over the top to avoid oil spray.
Re-indexing the talas system is a bit of a chore, I wish I’d made something to centre the sprung inner piece – it’d be so easy to bend/break the little driving pins without care. Glad I bothered though, the fork feels much better for it. It’s a Talas 2 by the way.
If I get a minute later I#ll dig a picture out.
