A plea on the VMCC discussion board discovered me slightly job this week – native BSA B33 rider Richard was on the lookout for a brand new factors backplate – the previous one had a stripped gap on the contact set clamping screw.
I volunteered to assist – I do that typically, it’s a great way to satisfy new folks, it prices nothing and it’s at all times good to follow one’s expertise. A fast Google revealed that whereas you will get contact units, caps and condensers for these ‘distributors’ – Lucas 18D2 or related, utilized by BSA, Norton and Royal Enfield the backplate shouldn’t be obtainable:
The 2BA gap had no thread left and the screw was in a nasty means too. I began by marking the opening place on the again, with a scriber:
Laid on the standard copper bar warmth sink, I set the TIG welder to 35 A and crammed the opening from each side.
I floor it flat with the Dremel and a file, drilled it for tapping 2 BA (4 mm) and recut the thread.
I cleaned it up with a wire brush. It took a little bit of Googling earlier than I used to be certain I had it assembled accurately:
Having delivered it again to Richard, and seeing his beautiful B33 which he has owned for 16 years I used to be happy to be taught it began right away. I will need to have assembled it OK!
It was nice to seek out just a few beers on my doorstep the subsequent day. That’s the type of charge I like.
