HOW TO MAKE FELT CARB WASHERS
Oddjob:
Cheers, for that. I have a 26mm and a 20mm hole cutter in the new set. It's better for them to stretch to fit rather than be too big.
Bryanj:
Sorry not measured the carb ones yet Ken, had a 15 hour monday night followed by 9hr break so not time ! Have found them so will try tommorrow for you
Oddjob:
No rush Bryan, I know what it feels like to do those hours, you have my sympathies

All the later onrs use a phenolic top hat type i think

According to CMS the felt washers are used on the CB350F, CB450, CL450, CB500, CB550K and CB750. If I make some I'll bung a few sets on Ebay.
Oddjob:
First attempt.
One problem, whilst I can do a 26 x 20 felt washer quite easily and a 12 x 8 easily I have found I cannot do the small ones for the choke as the cutters for the 10 x 6 that they require both use the same mounting position so I cannot cut them both at the same time, unlike the others. Plus after checking a 500 carb body it would appear that the 500 is the same size as the 400, the problem is 9mm is too small and 9.5mm is fractionally too big. The shaft is 6.8mm. There are no 9mm cutters in the set.
Looks like I'm going to need to get creative.
A swinging arm washer and 2 lifter washers. I didn't hammer hard enough for the swinging arm one, hence why it's a little fuzzy on the inside edge. They do seem a lot more robust than the previous ones I made by hand.
