What are the two angled screw/adjusters for RAF?

If you are looking to salvage the old gear to put on the new motor and it is brass then I would try a hot air gun on it with any luck it will just drop off. Install it while it is still hot by the time it is cool it will be a tight fit on the shaft.

PS handle the hot item with some pliers but be careful not to damage the teeth

Much more fun with a cigarette lighter!

Spare mandrels for different size shaft diameters. Replace the in-use mandrel as required, by screwing into the main Tee driver.

Gotcha thanks.

The thin mandrel was very soft and bent then broke off, so I had to drill the mandrel body out to take a hardened steel rod in lieu. The heavier mandrels haven't seen any use yet.

That looks quite good - where did you find it?
