Thanks,

OK, its "Show My Ignorance" time!

I still haven't use my sandblaster however I had assumed that you would only vector cut the mask and weed the parts to be blasted. Is there an advantage to rastering the blast area?

If there is a lot of very fine detail I can see the raster would be better and faster, but if its a large area it would seem weeding to be faster.

Guess I better get going on this, so much to learn, so little time. I'm still waiting for the contractor to finish my interior shop walls so I can hook everything up and get blasting.

Jim,

Some of the masking material can be very stubborn to remove from the substrate (from what I hear).

With that in mind, I would think you'd be better off rastering the blasting area and not risk damaging part of the mask during the weeding process.

Chris,

I meant to say Specialty Tapes. I have a customer named Specialty Industries. Duh! Here is their info.

www.specialtytapes.net
800-545-8273

The stock item I use is a 6" x 25 Yd. roll. It is called Lazer's Edge, and is item CW-5764-625. $25 per roll if you buy onesies.

Jim,

When you vector the material, you will also create an outline that will end up being deeper than the rest of the blast. I would not recommend vectoring, but it can be done.

Another factor you need to take into account the amount of time you would spend weeding your image.

Thanks for the information everyone. Hopefully, I'll be able to answer some questions about sandblasting sometime instead of just asking them. My first attempt was worthless because I used the laser settings that Rayzist recommended and it did not raster through the mask completely. I blasted and it didn't do anything. At least I didn't ruin the glass. I have a better idea what to look for now. One more question (yeah, right). What do you use to cover the rest of the glass that is not being blasted to protect it from accidentally getting scratched by stray sand?

Chris,

I've seen duct tape and sometimes masking tape used in areas where etching isn't desired.

I suppose the thickness of the covering would depend on how hard you're going at it, with regard to nozzle pressure and the depth you're trying to achieve.

Thanks David. I wasn't sure if masking tape, even multiple thicknesses, could take the punishment but I've finally got everything set up and am going to try some blasting today.
