I have just finished seeing the collection of this member's laser host from the Lifetime17
And what struck me and liked me was precisely that "black powder" what is its power?
The procedure used to give it the opaque black color is to spray it with black powder with a compressed air sprayer
And then put it in the oven at 450 ° ?

Hi,
Precise the host is charged with an electrical current at a certain voltage. When the powder is applied it adheres to the host bonding together
The higher the volts the better to avoid the Faraday Cage Effect , meaning that the charge runs through out and into all the grooves and detents. Otherwise the current just runs along the surface and will not adhere into the grooves.
Temperature is important in the process 450 Degrees seems to be sufficient in curing the powder to the host.
Powder coating is way stronger that paint and anodizing and has a better hardness to resistant chips and nicks.
With in normal handling and usage. Hope this makes it clear and to the point. The object being coated needs to clean of all dirt, grease and oils or the process will fail . The process is time consuming but the results are amazing.

Hi,
Yes the procedure is that, I have precisely seen it on this video that I am attaching to my answer! I could never have asked you if the procedure had been that without knowing it before ....
Skip the intro and go straight from 5:53 onwards, even if the powder used in the video is a light green that then becomes "shiny bright" after being in the oven
However in the end, the result is superb

P.S. Do you also use the sandblaster before making a powder spray?

Christian :)

Hi,
The brightness depends upon the base coat , is your coating AL and is finished off polished you can use a translucent coating. Or if you have a piece that's of another material the base coat should be done in a silver base or a white base to achieve this effect. With heavily rusted material yes a sand blasting would be great to get it down to the original metal . Then cleaned and sanded or buffed smooth.The video shows how it should be prepped before coating.
There are different types of powder solid gloss. solid matte , Translucent ECT.. All preform different in a finished product.

Hi GSS,
There's something about powder coating and copper together just seems right. I think I'm going to put in a 488 in that white powder coated side button 1X14500 host. I think it would go nicely ..

Hi,

Sorry if I answer only now, but work is work!
Now I have just less than an hour left!
Today was a very tiring day, and tonight it will be more!
Smart people often travel at night and we wait for them at the gate.

This shiny blue / cyan blue host is also very beautiful and elegant
As it is also that of GSS in small photo and the other at bottom thread ...! so if I understand you do you deal with painting the hosts that LPF members send you? and according to their needs, do you paint their hosts? my compliments then

Hi If your referring to powder coating not painting, Yes I can coat hosts only if its aluminum and has no electrical components in it , It must be bare . If I have to refinish the surface that will bring a small additional cost for the job. The Blue host your referring to has a translucent finish over polished aluminum.

And for the GSS Black Satin build the diode and driver are set into the copper heat sink.

I understand, well, it must be fun but at the same time tiring to paint the hosts! especially the small ones,
So the aluminum hosts the LPF members buy them from one of you? or do they have them made naked by a skilled turner for soft metals?

Aha, then I make you my most sincere congratulations again, you are doubly good, be careful if you export these hosts to Italy and advice from member to member that I give you ... (read my unofficial private investigation)

Hi
Thank You there is no problem to ship a prewired host abroad, Its when its a full laser build then there's trouble with customs.

Yup the host is powder coated AL and the head/focus knob is Copper with a 12mm copper module pressed inside.
I sprayed Krylon clear coat on the front copper to keep it shinny. It's been over a year and it's still keeping it shine..:)

Good morning Rich,
Exact, empty host only with ON / OFF switch disassembled in 3 or 4 parts ... yes .... complete host ... no confiscation and monetary fine.

Good morning GSS,
In fact it still retains its brilliance ... seeing it better
