Electro Lumens Search and Rescue ST90 upgrade. Completed post 31, 17.2.19

Lol, how much of the original light will be used in this?

The less the better for us, we like watching :nerd_face:

Great job :beer:

Appreciate the comment. :beer:
The head assembly is the only used item from the original torch.
Theres not a lot left to do. The tailcap to finish off and then assembly. Just need time.
There was a 12 hour race on idiot box yesterday that got in the way. :person_facepalming:

I missed this one awesome project!

The hacksaw looks like its steam powered :stuck_out_tongue:

I was at the Bathurst 12 hours yesterday i watched about 6 hours from half way. It was so damn hot. I went for a walk to see if i could find Mick Doohan but could find him.

It was steam powered when l was using it as the shed was a sauna. Micky Doohan was in the 888 teams garage and the Mercedes area. Not sure he ventured much further than that. Was a good race on the tv.
How was the noise from the different engines? The Bentleys were a rockets at one stage. Shame the driver stuffed up twice at the end of the pit lane.

Yea most of the cars where not to loud compared to other events like V8 supercars or F1. Loudest car was the mustangs freaking deafening you could also hear the turbos spooling comming around the bend. Like the aston and merc must have been big bores they where just rumbling.
I think the Aston Martin is a V12. The Porsche GT3s didn’t sound that great but they got the job done.

The end was good safety car came out with a few laps left. I seen one of the Aston Martin retire with a few laps left i think. Also the KTM came back on car carrier with a few laps left. Bloody Nissan i didn’t see what happen but they hit some one and got disqualified.

I was at the start of the main straight where the start/finish is. I bought the mountain pass drove up but not much room by the time we got there so i headed back down.

Took my esky and fold up chair and decided to buy a beach umbrella from bunnings. Lucky we did it was a crazy hot day. I had a tarp and rope with me was hoping to set up under a tree lol.

The Nissan got disqualified because they did not come in for a drive through penalty. Just kept on going around.
Talking about being hot. Someone had a temp gun and pit lane surface was 69 degrees.
Sounds like you had a good time. Thanks for the update. :beer:

Todays update brings us very close to the finish of the upgrade.

The tailcap was placed in the mill and 12 x 12mm grooves were machined into the side.

Holes for the wiring and hold down screws for the MCPCB were machined into the pill.

A comparison of the discarded battery tube with the final product showing why the tube was welded up.

A copper plug 2.1mm in length was soldered to the Lexel driver to allow the battery tube contact to slightly compress when assembled.

And finally a few bling shots.

Battery tube.

The pill and driver retainer. The retainer was machined slightly as the earth ring on the driver sits slightly below the driver surface.

The pill.

The driver uninstalled and installed. On initial testing the driver did not work which was traced to a faulty switch.

And finally the completed tailcap.

:heart_eyes: sweeeet :+1: Heavy Duty Search and Rescue Light!

. Love the Knurl Job! :beer:

Lots of shiny parts :heart_eyes: very nice

After the switch failure yesterday which until diagnosed causes just a little anxiety we have light. Always a good sign when finishing a torch.

I’ll finish with a couple of pictures with the Old Lumens tribute torch. Both these torches have the same reflector.

Thanks all for reading and your comments. :slight_smile:

That looks awesome! A wee bit bump up in lumens too!

Thanks Louie. I haven’t done a comparison yet but should.

Awesome work there Steve, love the knurling… maybe some day I’ll figure that bit out….

I dont know the secret to knurling. most times it works and other times not so good. It is hard on the machine though.
I should also have added that the owner requested the emitter be dedomed. which now is.

Nice job! That was a neat idea to add material to the tube by welding and it looks like it worked perfectly. The pill looks awesome and I think it fits with the aesthetics of the light. A performance upgrade that gives it the bite to go along with the bark. :+1:

Thanks EasyB. I tried to keep with the original design of the torch in respect that everything was built simply and tough to do a job. It was a big heavy torch and still is. :stuck_out_tongue:

It IS a very robust light! My friend in the NorthEast sent me one to bump, says for all it’s heft it was rather puny in output. No driver, two switches each used a different amount of resistance to run. I changed the wiring and got it doing over 20A and making good output but still didn’t put a driver in it.

This creation is just art, any comparison for throw beam shots? I can’t wait to play with it.
Tho thinking it might need that black anno removed so as to match the rest…. :question:

No beam shots :frowning:

Great Welding job, no pits. :+1:
.
‘MRsDNF’ you look like a First Class Machinist and Welder to me. Very Nice finish. :beer:
.
So have you had any problems running that 20mm mcpcb at 12v 8a with 8 x 18650 batteries ?
.
I have a very similar driver from Lexel with that same setup in a MT35 Plus and have burned up 2 leds and 1 mcpcb.
Funny it is back on the operating table now getting machined and modded for a 32mm mcpcb now so it can be held down with screws. :wink:
