I have a machine at workthat can do that sort of stuff. It is a CNC laser engraving machine. Maybe I could work something out with you, email me at [email protected] with specs on how big the plexiglass is and the logo. Thanks.

Actually it is quite easy to do with a small sand blaster. Several how tos' can be found online.

That's what I would do... Just tape out the logo, and frost the rest of the plexi with a sandblaster... I've done some stuff like that before.

The laser engraving will have a much better effect and look versus the etching.

Yes, but one is much cheaper than the other.

Couple of tips for those that want to try this themselves.

Any cheap blaster will do (Craftsman, Harbor Freight) with low to medium pressure.

The finer the blast media, the sharper the results will be.

Finally I prefer to remove the protective tape that comes on plexi and replace it with two layers of green painter's tape, then draw and cut out the area that you wish to etch.

What does a cheap blaster cost? And true you can do simple shapes with a blaster but a laser will do awesome detail work. I have access to a laser, I'll get a sample and see what pricing would be if anyone is interested. I was planning to do a panel for the bottom of one of my amps anyway.

well preety much i could make my own and go to all the hassle of cutting ect, or blasting it ect...but i figure i can just buy that one and flush mount it on a piece of 3/4 MDF...like...its kinda hard to explain, but i would honesly have no need to teh actually light bar part of it, just the piece of plexi, so my first question is...

hwo would i cut teh ligh bar completley off, table saw?

adn my second question is hwo would i fit the LED's in teh MDF without actually seeing the bar and just the glow


did i just confuse u more, lol...hope not

Well the picture on ebay is carved in the plexi, not etched, and some of the 3D effect is lost with etching. However, when you heat the edges of plexi, it clears up like glass, so light transfer thru it to create the effect you want. Once you rought out a channel to accept the plexi, you can glue, screw or frame the plexi in place. Wire up 1-4 LEDs along the edge and you are done.

Make sense?

i got that sandblaster, but to get it to light up do u need to drill holes and put the leds in or just shine them on the plexi

You will have to make sure the edges are clear, but you can light them however.

mask off the plexi and cut out the design, and sand it, iv done it many times, works and looks good.

You can pick up an airblasting set from many art stores for as little as $40. Comes with the aluminum blasting media, the brush/gun, hoses, and everything except the compressor.
