Brushed advice

[barry]

It seems I've not cared for my brushed wet weather car properly, only using it for the odd wet race and chucking it back in the box when I'm done. However, this meant it could not manage a full wet meeting yesterday at Carlisle! It would get about 5 laps in before the car ground to a halt. Fiddling with the brushes meant I got another 5 or so laps before it stopped again.

Anyway, I have a lathe from ebay which I'll dust down this week, but I was wondering if anyone could give me some advice about which brushes/springs to buy and any other maintenance tools/lubricants/techniques I should get/learn?

Also, a good stockist for this stuff.

Thanks in advance,
Barry
