So the green car in reply #11 has a mixture of Oscars and Super Oscars ?,I have a set with will go on my car but how do you tell between the 2,is the "super" the larger of the two? mine have 150mm lenses if that means anything.
Just wondering how solid these brackets are ? personally don't like light beams that bounce around.
How did these cars handle the power demand for these lights considering the original were very low output,I have a relay setup with my Cibie's that uses heavier wire thinking I could use that.


On Cibies: First off - am not an expert! - but I found this on Super Oscars:
https://www.ozautoelectrics.com/cibie-super...100w-220mm.html

and regular Oscars:
https://www.ozautoelectrics.com/cibie-oscar...y-headlamp.html

..and the sizes seem to scale for what's on the green Meaney car...? So yes, seems the Super is bigger.

On brackets: yes, have been in a few cars where driving light wobble from flexing brackets can make you quite nauseous! The ones I fabbed up for my car are from 3mm mild steel and maximally braced - so no flexing there.

On power demand: so all my aux lights are relayed and fused in pairs. As for alternator power, I'm not sure if higher output alternators were used in period or not, but for endurance racing, en engine spending most of its time on high speed tracks at high revs will allow maximum current output from the alternator; lots of time spent at low revs and idle would be relying on the battery reserve more to power the lights?

- Tony


Thanks Tony,I will go with your design or similar as I will try to sink mine into bumper cutouts as much as I can,mine appear to be standard Oscars (IMG:style_emoticons/default/beer.gif) .

Only real Dicks add aux lights, says Richard.

I'm inferring the Rennenmetal brackets are NLA - I have a new uninstalled set in storage which I don't want to sell but would loan out for someone to measure/scan for duplication... PM if anyone wants to pursue that.

Finally had some time to start copying out the brackets, sketch has measurements in mm (sorry for the crappy penmanship) and I've cad'ed out of version of them with and with out a little brace piece. Rennenmetal had added a little weld in gusset, I was going to try sheet bending in a tab and welding it after the next bend.

I still haven't set up my new plasma table so haven't had a chance to cut them and compare to the originals but that shouldn't be too far out.

I'm 90% there, but haven't finished setting up my new plasma table and have been focused on remodeling our house during the "shut down"--should be getting back on this shortly and will come back and update this thread.

Such a weird coincidence, I was just wondering about how this was coming along, and then the thread gets revived (IMG:style_emoticons/default/driving.gif)

PM'd about production idea, I can get these cut for you with out the slag associated with plasma, tighter tolerances, and many more material options at your disposal.

Wish I saw this earlier, I would have taken Chris up on the offer to duplicate these. I helped with the prototype work on the original brackets, and was offered a set for the help, never got them.

But will gladly pay for a set as I want to have them around.

These aren't mechanical parts and if the plamsa cutting is done well, you get not only pretty good precision in terms of measurement but also very little to no slag anywhere. The original brackets IMO are pretty sloppy in spec, but they could be, because they were only there to mount lights and not really serve a mechanical purpose.

Responded to PM (IMG:style_emoticons/default/beerchug.gif)

Example of plamsa cut, this came off the table like this, I just torch blued it to make it look more interesting, note the detail etc, plenty good for doing light brackets and then some:

Eric, has shared with me his work on this. I will run it trough my cad and do a laser cut in Cardboard Aided design. Then clean up the design a bit to make it easier for production.

None of these issues are from anything Eric has done, it is from the original design.

Eric I agree with you Plasma can make some great cuts. and has it's place. I tend to use laser based on the wider range of materials and higher tolerances that I tend to work with.
