  1. Cause it's easier and faster to find someone that already has done all the work. :)

    A note on recreating it if you can't find a kit, that stripe on the top will not be as simple as it looks. The curves of the hood and ruff mess with you and a straight piece of vinyl will not go on straight on those curves. You're best bet is a good wrap vinyl and some knifeless tape.

    Thanks everyone for the info and the grit numbers i needed,Just out of curiosity, is it possible to take the top filler cup off of the eraser one from harbor freight and put a hose on it instead to see if it would create enough suction to suck ? Maybe? lol..

    I don't believe so, at least not easily. If you want to go the air eraser route, you can build a little blast using a plastic tote. That's what I did to start with. Worked ok for doing glasses but took forever, 15-20min, to do a single glass where as with the siphon gun in the cabinet I could do a glass in about a minute. I believe I posted photos of my setup on here someplace.


  3. Most blast cabinets come with a siphon blaster, so no need for an air eraser, you'd quickly out grow it anyway. Bench cabinets are nice, but the one downfall they pretty much all have, is the sides of the bottom are not steep enough to get media to slide to the bottom where the siphon intake is located. They work well enough, but not as well as a self standing unit with steeper sides. And just a quick note on siphon blasters, do not bury the entire metal siphon under the  media, the top of it should be up in open air. (took me awhile to figure that one out :) )

    Personally I'd skip the HF unit. The problem with theirs and several others in the low price range is that it is put together with nuts and bolts and as a result has a lot of places for media to leak out. This can be fixed with sealant, but for just a bit more you can find a cabinet that is all one piece. Usually Rotomolded plastic. Nothertool has one for about $200.

    As for grit, that depends on the look you like. The higher/finer the grit, the more of a dusting effect the etch will have. The lower/course grit will give a courser surface. For glass I like something around 120 grit. They type of media also plays a factor, for glass Aluminum Oxide is pretty common. It's not too expensive, and lasts pretty long. Even with a blast cabinet you should still consider some sort of respirator or dust mask, no such thing as being too safe.

    Lastly, get as big of an air compressor as you can afford. Blasting uses quite a bit of air and a small compressor will be running constantly to keep the air supply going and as a result quickly burn itself out. I have a 10 gallon unit, it works well, but it does run a bit more often than I'd like. One thing that confused me in the beginning was looking at the require CFMs of a blaster vs the CFMs of a compressor. The two do not have to be matched up. Once the tank of the compressor is full, it will provide what ever the blaster needs, it'll only be restricted by the hoses and fittings. Where the CFM of the compressor comes into play is how long it will take to refill the tank. So if you compressor has a higher CFM, you can blast non stop. If your compressor has a lower CFM you will need to pause every now and then and give the compressor time to refill the tank.

    Also, the larger diameter hose you can get, the better. Larger diameters will allow higher CFM, should try to go 1/2" at the min.
