When you assemble the gearbox, does the gear sector quadrant go in a central location (i.e. in the middle along its length of travel onto the camshaft) - that is how I assembled it. Not quite assimple as that, Steve. on the end of the selector shaft you'll see an '0' stamp in the valley of two teet...

Helo, Dave. Im no expert on WD machines, but is it yellow enough to have been 'desert camouflage'? Were Ariels used in the sandy theatres of war?

Ive fitted a Thorspark to two bikes - a Matchless and a Panther. Theres no need to remove the mag and its easily reversible should you change your mind. The only issues are with setting the timing up - it needs to be done with a strobe light for full accuracy as the felt tip mark for the trigger poi...

Tracy Tools are excellent to deal with and good on prices too. You could save a few quid by buying the ordinary carbon steel taps and dies if you are only going to be cleaning threads up. They'll cope well with cutting just a few new threads, especially if you are able to cut them first on a lathe, ...

I needed a mag rebuilt for my 1948 Matchless G80S and after a 5 month wait for another mag for my 1926 AJS 500 from Armoto, I gave Matthew a call - per their ad in CdeF. This was on a Thursday lunchtime. He told me he was about to start on a batch of armature rewinds and if I could get my mag to him...

I must admit to feeling a little despondent when I read your post, Paul. I had visions of all sorts of mayhem and aggravation being uncovered. However, the Spirit of Ariel has decided to grant me a respite. Geoff Brown of gearbox spares fame was extremely helpful and sent me a speedometer drive kit ...

That's interesting, Paul, thanks. I have a dating certificate from 1990 that confirms that the bike, originally an NH350, was despatched on 26/5/37 and the old brown RF60 shows the date of registration as 25/6/37. It now has a 500 OHV engine, the dating certificate for that shows that it was despatc...

Thanks, John. Ive been in touch with Geoff about it and it could be a little engineering adventure with the Boxford is on the cards. Stripping the box wasn't my first choice - Ive done it a few times on my 37 Sunbeam which had a noisy BAP box (but no speedo drive) I cured that eventually and at a pr...

That's an option I'd not even considered but worth a thought. I've had a message from Geoff B - he has a kit which involves replacing the worm gear on the end of the layshaft and fitting a matched spindle. Life's never straight forward is it

Thanks for the info, Roger. I had a feeling that problems were afoot and nothing is simple I vaguely recall reading somewhere that the X denoted an oil seal but haven't been able to find where it was Aint age wonderful?
