I am building a sub box for my gf to put in 350z. I am planning on putting the amp on the back of the sub enclosure under plexiglass. She is wanting the plexiglass to say "fairlady z". How do I get the plexiglass to have frosted letting in it. Is it etched? What do I need to use to? Thanks for the help

 

Duct tape what you don't want frosted, cut out letters in the duct tape, remove letters so you can see the plastic, sandblast lightly.

Works on glass too.

 

Awsome thank you

 

^You can also buy some clear frosted spray paint instead of sandblasting the piece. Very easy and sold at Home Depot:

I'm debating on what method to use. If I go with sandblasting what size media do I need? Fine? Or coarse.

 

Or get a decal,they have them that look like etched glass

 

i attempted to make the enclosure today but failed. Any tips on getting the angles correct. Im having trouble with the angles where 2 pieces of wood come together

heres what im trying to build

 

if you look around at some arts and crafts stores they sell the proper material for covering the glass in prep for blasting. it's a rubberized adhesive sticker that you trim and stick to the surface to protect it.

duct tape seems pretty ghetto to me, considering how much a thick piece of lexan costs, not something you want to screw up on.

 

Getting the angles to match or getting them smooth?
Use something like a bucket or can to mark the wood

 

Getting them to match and the box to be "square"

 

flo rotory, it's all geometry. Biggest thing I've learned from building sub boxes is measure and plan in advance. It may sound silly but seriously - draw out exactly what you are wanting. Shoot, grab a protractor to get the angle perfect or trim some cardboard at the angle you need and then mock that up on your box.

If you are specifically talking about /_ getting it straight/square where the two pieces come together you'll need to use a table saw at a specific angle to back-trim one of the pieces so that it mates up with the flat edge of the second piece. Kinda difficult to explain, but if you hold two pieces of wood together at the angle you desire, you'll see that there's no possible way they will be flat against one another unless you make an angled back-cut on one of them.


Also, for the frosted plexi glass, if you do it the "official" way, you'll use fine media. But, they also make "frosted" decals that you just cut what ever design (with an x-acto) that you want into it, lift it off like a sticker and place it onto your plexi. Much, much easier and less risk of screwing up perfectly good plexi.
