I'm needing to make a new thrust washer for the rotor drive sprocket on an
old Howard 300 rotovator, but I'm not sure what material it's made of.
Initially I thought it looked like copper, but after having to heat the
bearing sleeve next to it, it now looks a more bronze colour.

Dimensions are 1.9" od x 25mm id x 2.5mm thick (aprox.)
I only need one, as the other side has negligible wear.
Also, any suggestions for where to get suitable material?
thanks

Maybe phosphor bronze? If so, RS components do 2" od x 1" id tube but
you'll need a mortgage as it's £65 + VAT for a 13" length
Their code is 682-028 but I guess there must be cheaper sources out there?

I'll have a look later on to see whether I've got something near I
could slice a piece off.

Nearest bronze I have is 1.8 OD x 0.9" ID.
You would be welcome to a thin slice of that if you don't find
anything better.

And I'll machine to size, if you give accurate sizes - will get two,
maybe three out of the blank.
My bits-pile eats money - can't give it away for free!

Probably a bronze or Berylium Copper.
Measure the ID,OD, and aproxiamate thickness, and get in touch with a
bearings supplier.
Chances are really good that it will cost you far less than making it
will.

You should be able to get a 25mm bore Oilite washer from BSL.
