I saw your website and video regarding sand blasting. It doesn’t look like your info is exactly what I need, but maybe you could help me out.
I want to go full time RVing and would like to have a way to make a little extra cash. I thought I could offer the campers their family name of maybe pet photo sand blasted on a smooth granite tile. I looked at the SCM System equipment and you are right about them being expensive. Making lettering might be possible with your info, but it didn’t look as if you addressed photos. The SCM System has a photo imaging process that seems to work.
How much equipment and what do you think the cost would be? Space in a fifth wheel trailer is also very limited.
The most significant part to photo etching is the stenciling process. You have to use a process known as photoresist stenciling. You have to use computer software to edit the photo and expose it onto a photo resist stencil material.
If you already have an adequate air compressor, you could probably get started for about $250. It will probably be about a hundred for the sandblasting equipment if you go the cheap route and a hundred or two for the stenciling and other miscellaneous supplies.
