hi, I have a old x3 mill bought from arc eurotrade a good while ago..ive been out of the hobby for a while but starting to renew my interest and have found that the carbon brushes on the motor most probably need renewing.. I've phoned arceurotrade but apparently the older brushes are no longer available .. does anybody know differently or have any suggestions on the best way to proceed.. I was wondering if its possible to make up new bushes …any advice much appreciated..thanks….Andy

Measure them and see if you can find the size on the net, they can always be trimmed down

thanks Jason , that's what ill do if I can't get them as supplied with the original motor.. they have brass caps attached to the brushes which locate in the brush holders.. it would have been easier if I could have sourced the specific item…thanks again

Anything bigger that will fit by cutting/filing them down will do – as long as you know whether the brushes are for an AC or DC motor.

Having read the above comments, its not just about the physical size and composition…..there is the spring pressure to consider…where springs are fitted

So not all brushes are the same

There is quite a lot of knowhow that goes into the optimum brush material and spring pressure **LINK** . Try to get brushes from a motor that is of the same sort of size and application, it is going to be better to have brushes that are the right size even if the material is not ideal as worn brushes can start arcing and the destruction of the commutator quickly follows.

An additional supplier link:

solenttools.co.uk

They recently supplied a pair of brushes for my old Wolf Grinderette angle grinder.

This machine is over forty years old and I was impressed to find that they were able to supply against the type number of the machine. They also undertake to make brushes.

I notice that Arc mention the size of the old style brushes: 12 X 6 X 18 long.
