As for felt,  I washed "her indoors" favourite merino wool jumper either too hot or dryer too fast  :-[  that's now only suitable for  felt washers. Was I in the dog house for that one. ;D

That's ironic, did exactly that this weekend thinking I was helping my poorly wife. Now where are those carbs.... ::)
One day I'll have the time to restore it, not just talk and dream....

ive got an old set of punches here that are just great.. .they have a centre pin spring loaded so you can punch the big one out first then just seat the inner one on the centre mark thats  left...and hey presto...washers...
think they came with aload of engineering stuff i bought..they are a few years old but they are fab!

This is the sort of kit we used at work-effortless concentric washers every time

Hiya, I know this is an old thread but would anybody that has the right punches be able to make me a set for my CB400F?
I’m having zero luck on the internet trying to find anything remotely similar!🙄

Great tip. What thickness grade A felt please, or does it come in one thickness only?

I tried to make my own but had trouble getting the correct felt. The stuff they sell in Hobbycraft doesn't have enough density and falls apart.
I bought a set from Mike Nixon in the US, here's his link:

Nice one Dave, spot on. I wasnt sure if anybody who'd bought the punches to make some might have been able to fettle me set up over the weekend or something. That links the closest I've got so I'll get some ordered up cheers for that you're a gent

Hi everyone.. I’m currently rebuilding my carburettor’s and have encountered the felt washers issue.
During research for felt washers I came across this old thread, unfortunately I don’t have anything to hand to use as a felt washer.
Would anybody be able to recommend where I could order some grade ‘A’ felt as mentioned in this opening topic along with the required thickness of felt.
Many thanks

I have the tools and the felt to make these Roo and CB-500. Do you still need some?

I must warn you, they are quite fragile so I tend to soak mine in Silicon oil as that not only helps them keep together but also aids in lubricating the lifter shaft that passes through them.

Start a production line as I’d be grateful for a set….or even two sets.😀

I've built two sets now without them, i was assured it wasnt a vital nessessity. They were so dear and I couldnt find the stuff to make it from. After I'd bought the punches and the felt and the postage, it wasnt worth the outlay for a handful of washers when I didnt definitely need them.

Get cracking Ken, you must have a bit of spare time to rustle up a quick 20 sets? ;D ;D

20 sets ?????? You know where you can go with that request. TBH they ain't hard to make, just fiddly. I'll make a few sets as soon as I get the time.
