Well - as I said on another topic yesterday, it pays to keep an eye on what's on the forum. Bet there are a few more GPOers gnashing their teeth today. wink

Cheers Stewart,

Happy New Year to you.. 

the Lucas link is useful, the photo showing the bracket is showing a different headlamp to mine so doesn’t show the problem.. Nick, below, has come across the same problem.. perhaps, two similar looking brackets were manufactured, one slightly longer than the other?

Good to see that being helpful has helped you regarding Nick’s mystery brackets.

Regards,

Alan.

Thanks Nick,

Happy New Year.

between me starting this post and you answering I have purchased a repro bracket, well pleased with the quality..

On a rough assembly the bracket is a perfect fit to bike, adding the headlamp the switch gear looks to close to top yoke.. I have options, I could make a spacer drop plate that would drop headlamp slightly at the same as moving it forward.. or else I could simply put a twist on the bracket back plate, that would also move headlamp forward and down..

I’m a bit like you, I was a blacksmith / welder.. eventually our workshop was merged with the sheet metal shop and we all shared our trades.. I retired fifteen years ago so don’t have the joys of all that equipment any more..

thanks for the kind offer of the drawings, if I need to, I’ll be in touch 🙂

I’ll probably post a photo of what I have later today..

Regards,

Alan.

I’ll add a PS to my last post, I could also slot the bracket holes to drop the headlight..

that’s a good looking bike Nick, looks like you’re like me and in need of a toolbox and battery holder.. 🙂

6D77890E-19CC-4B80-A67E-C2E2DC9F7537.jpegYou can see from this shot, the standard bracket seems to be a touch on the small size. What you have to remember is that there’s a switch panel to go on top of the headlight.

I’m still waiting for the switch panel, the seller delayed sending because he was away for the Christmas period. The headlamp is just held on with  a small nut and bolt until I get some bsf nuts and bolts. 🙂

Hi Alan,

Thanks for your kind comments regarding my D1. It's actually a hybrid with a D5 175 engine which has a larger carburettor than the standard D1. I have the tool box, but there is not enough room left to fit it due to the larger carb.

I have the original Lucas engine but it's in a bit of a state and wants a lot of time and money spending on it. It spent 2 years under a caravan with the barrel, head and piston removed, before I got it. I am planing to start work on the Lucas engine later this year

One thing I don't have is a battery bracket. If you have one, I may call on your services and ask you to jot down some measurements for me if possible.P1040005.JPG

Alas, I am like you, I still need the battery bracket.. rest assured, if I find one I'll let you know the measurement if you still need them.

The battery box and battery holder is a bit of a blocker for me. I'm scrapping the weird wiring and doing a complete rewire but the battery box and bracket I need to fasten them too.. I'll get there in time, there's plenty more to sort..  🙂

Three photo's to upload..

Two of them show the problem I have with the headlamp fitted to the standard bracket..  made even more awkward now I've added the switch panel.

The switch panel almost fouls the headstock, the headlamp is too high and too far backwards... 

Nick has kindly offered me measurements so I can make make my own bracket, which is what he had to do.. but surely there must be an original correct bracket somewhere??? I think the headlamp is correct for a Lucas bike..

Not sure about the switch panel, it fits perfectly, all holes line up exactly.. just added a photo of it because I hadn't seen a panel without the ammeter..

Hope I'm not cluttering up the place with all these photo's 🙂

Looking a bit big.. i'll get used to adding photo's eventually... maybe 😉

Err - I think you have that bezel back to front.

Hi cocorico,

i don’t think so.. if you mean by bezel, the switch panel, it’s the right way round. The thin end is to the back and that’s where the cables come out of.. this bezel / switch panel is unusual as it doesn’t have an ammeter in the front 🙂

Of course, I could have completely misunderstood you 🙂

Ah, I see. The switch panel does not appear to match the profile of the headlamp shell. The rubber trim around the panel wouldn't make enough difference either. Can you get a spacer between the brackets and their mounting points to see if that improves it? Apart from that I can only suggest trawling through the links to Lucas Electrics on the forum.

The panel does match the headlamp’s profile perfectly, I just haven’t screwed it down.. I still haven’t got the screws or the rubber trim, just doing a dummy fit which may be causing you the confusion.

I’ve been looking through the forums, seen some bikes with the same headlamp but can’t find anything to show a different light bracket other than the one I have. Nick, earlier on mentioned the same problem, he had to make his own 🙂

Cheers Stewart, 

I have seen those photo’s, but they don’t show the bracket holding the headlamp.

It did make me look again at the line drawing on one of those links. It has the same headlamp as mine but it sits much further from the forks.. there must have been two similar headlamp brackets, one longer than the other.. I can’t find any mention of the longer one though.. see picture below..

thanks for the help 🙂

The mind boggles as to how that line drawing went to the top of the post instead of the bottom... ???

Don't know about shedding light - but have you read the small print in the middle of the Draganfly page? "...Lucas list 200 headlamps in 33 models between 1936 and 157..." - makes your toes curl.cant-look

Looks to me as if you could drill two new holes in the bracket lower down to get the correct clearance

Draganfly don't list the Lucas Headlamp for a Bantam type SSP575P /.....

and if you search the appropriate Bantam parts book you will find the Lucas equipped Bantams used different Headlamp brackets.

90-5054 = Lucas

90-5013=Wico Pacy

I doubt you will be able to buy a Lucas bracket, the best you can do is to get someone to measure an original Lucas bracket and make your own, or modify what you have.
