I replace mine with modern sealed ball bearings. They are cheap, use
the original axles and fuss free. All you need is a lathe to make a few
spacers.

PM me and I'll send you drawings. Or, when my transcontinental move
is over, I'll sell you a take out set. I'm in the States.

Cheers

Hi Robb,

Thanks for the offer but I am an engineer of 45 years and have access to machining facilities. I have all of the bearings now and just need to make the spacers.

Cheers

Tony.
