A modern one is already on order.

that make up the diode bridge.
And potentially replace one if it goes bad.
Dunno about that R1 .....

British Bikes / Ariel Arrow?
« Last post by ramwing7 on June 11, 2025, 02:23:23 PM »I've pulled the wiring loom from my 1962 Ariel Arrow and am finding all sorts of interesting mysteries. The current on is a "what's this". Pictured below is what I'm thinking is some sort of rectifier. I've never seen something like this, but it doesn't have anything else I would call a rectifier.
Anybody have any opinions?
Thanks.

« Last post by cardan on June 11, 2025, 12:03:21 PM »That pic of painting the tanks is a good un ! We wonder what an infrared oven was though ??
Sorry R, I missed that when we turned the page. "Infrared" suggests the oven/parts are heated by radiant heat (radiation) rather than a gas flame in the oven heating the air (convection). I suppose the "things" on the side of the oven in the photo are infrared heating elements - think mini/very low power electric bar heaters. No air movement so no dust.
I don't mind the Acme. If I had a farm to potter around I might bid at $2000.

I’ll keep watching (if I remember).

British Bikes / Re: Villiers XIIC 148cc doesn’t run anymore
« Last post by 33d6 on June 08, 2025, 09:57:02 AM »There isn’t much comfort in checking the mainshafts for truth. New mainshafts aren’t to be had. Villiers mainshafts of the period are integral with the flywheel. They can be be ground circular undersized up to .005-.010” off but the centres have to be unmarred and dead true plus be set up dead true to the big end assembly. Not an easy job. I’ve chewed this job over and over, reluctantly coming to the conclusion it’s probably just as easy to make the whole assembly new from scratch. Either way is a drama.
On the plus side the two crankshaft halves are identical which is both a blessing and a curse as it both makes the job easier but is wide open for enthusiastic owners to unwittingly end for end the crank assembly when putting things back together. The wear patterns are different for each side so end for ending speeds up the wear rate until the original patterns reassert themselves.
Old British two-strokes are of dead simple construction but quite subtle to get running really well. Charging in with lots of enthusiasm rarely ends well.
