Hi Paul, Thanks!
I got the brushes from Woolworths, it was a broom brush cut in half.
I got the rubber seals from a local V belt and rubber shop.
I have no idea of the stock numbers, but I can inquire.
The gate opener is operating at 30% of Max torque to open and close the roof, I spent some time on this getting it right. The pinion is steel, and the rack has a 10, maybe 12mm square steel bar running inside it for its full length. I'll post a picture. Then plastic around it. I had the motor running at 100% torque, and making it stall, there was no issue with the rack failing.
I few rods, yes, and about one and a half coils of wire at 15kg each.
Regards Joshua
