TR2/3/3A Old trick on SU's

Some may think this one is crazy. Never rebush your SU's or replace the shafts.
All your wear is ON the shaft and is visible AND repairable. Again, metal bonding epoxy is a modern miracle.
What many do not know is that this epoxy has micro beads of glass in its matrix giving it a good surface after
machining/polishing.
Repair your old shafts after cleaning/sanding.Just a dab. Next day, file/sand it until the fit is just so. Use a good synthetic
grease to lube the shaft when re-assembling Lasts forever, quicker,cheaper, faster. Two throttle shafts take a total
of 45 minutes(don't count cure times). I have done many sets over the years,no issues.

What a great idea! I'm going to try this on a pair of older H6 SUs as a science experiment.
(Along with another thing I'd like to try: the racer's trick of using epoxy on the inside of a (very clean) intake manifold as a way to shape and direct airflow into the cylinder head ports)

What brand of epoxy is best.

Interesting... reminds me, I once used West Systems epoxy plus graphite powder to repair a sailboat rudder shaft that had worn (in that case the shaft was aluminum - i.e. soft). Built up the shaft, waxed and put the bearings on the shaft, let the epoxy cure, and sanded down just a touch to give a wee bit of clearance.

It would be different if the new shafts were ready to install and not a pain
in gluteus maximus. Down to the tiny roll pins for heavens sake!
