Thanks Charlie. I’ve thought about shrinking the collar onto the shaft and that still is possible. Initially I thought that heating the shaft would distort it but having thought about it for a while I only need to heat up the collar.

So yes, good call.

Thanks Stuart. I still like the idea of turning the shaft down and fitting a collar over top of it. Welding may well distort the shaft.

A bit of superglue (Loctite 480) should hold the shaft in place if I have a small clearance fit of a couple of thou.

If this is the route I finally take, I shall let you know how I get on and any problems I’ve had.

A few more photos of the gearbox before stripping down totally.

GEARBOX

The gearbox is presenting some challenges. There is a large crack in the casing, but I believe I can get this welded. The shaft that the worm is on has worn to an unacceptable level. It would appear that the shaft was originally 25.4mm or good old 1” and has worn to 24.2mm or 0.950”. Can we stick to good old English measurements now the…[Read more]

The Coleby Junior is now dismantled. The engine and clutch housing has been separated, the clutch housing and the gearbox has been separated and the gearbox has now been stripped down. The next couple of posts will detail what I have done so far with a few pictures to help the descriptions.

I’m a little busy tonight but have started a “what I have done so far” write up. I need to take a few photos,…[Read more]

Thanks Andy, yes you are correct, the CJ series sounds about right. It’s worth me remembering you have the 25A spares since I would love to find an early Coleby and restore that at some point. However I need to walk before I can run.

Both are fitted with the JAP 4/3 engine but both have the newer magneto. I’m not sure whether the one I have purchased in Kent has the correct Magneto for its age, but expect the one I’m using for the restoration project will be fine to get the engine going.

I do have the Wico 2A magneto but can’t get the screws off the coil cover at the moment.…[Read more]

Hi all

I’m new to VHGMC and my interest has been started by my purchase of a Coleby Junior in Kent. This was owned by a member who has told me about this club and having read a bit about it, duely paid my subs.

So, why the interest in Coleby? My grandfather worked for Fred Coleby and after Mr Coleby decided to sell the company, my grandfather…[Read more]
