L T P;s new builds light bar complete @141

a little more progress today made 3 plates for the base

this machine rocks for drilling !

the trial unit still going strong on the front of the car, no driver issues.

You are getting lazy in your old age. What happened to a bit of blue, scriber and centre punch?

cant find the scriber or the centre punch .

cut the lenses

these are Lexan apparently tougher, but acrylic is more scratch resistant.
can allways make more if needed.

started on the pockets for the led’s/reflectors

next pass is with a ball mill then a skim for the leds

Looking good LTP. When your not working I’ll drop in for a look.

ok

first pocket for leds

about 1 1/2 hours each.

Had a little on of late ,have also upgraded the computer on the machine,

todays effort the other 2 pockets.

some machine vids hop they work

so will need a skim in the bottom of the pockets for final height/depth.

Nearly there

Did you use primer under the paint?

I tried painting a light but the paint doesn’t stick good. The primer helps but its still not as good as anodizing.

just engine enamel ,guess I will se how it goes.

have you tried the bake on exhaust ceramic paint evdsg

Nah i haven’t but its on my list of things to do. I am on an Aussie EDC page on Facebook and some people swear by cerakote. There was an older thread on here talking about it.

I am not sure what abuse the light bar will see, but i am wondering if things like sand or tiny rocks hitting it will be an issue at higher speeds?

Where as my painted light was used as an EDC on my keyring so it was well abused.

You are right .I am thinking paint jobs will come with lense replacement.2 of the lenses are lexan 1 is acrylic. I am told acrylic is more scratch resistant.lexan stronger.so will see how it all goes.its all a learning curve all be it a expensive one.i think I’m well over the $400 au mark.makes rmm’s bars cost effective
If you add time in.

Looking forward to seeing the final product.

Do you have another light bar to compare the beam with ?

Only a ebay/osram thing. which draws about 9amps.this should draw over 30amps.

A bit of a tease,

mounted the leds and wired the centre section

as thought each bank of 4 leds draw 11.2amps.

this drops if the car is turned off ,

Was that running only the bank you were testing or running all three and testing one?

just one bank of 4leds. haven’t finished wiring the rest yet.

Aah, I see. Just wondering if the auto electrics can maintain that current for all three ? I don’t know much about it ???
