How many sockets are in one of those units? Speaking of tearing things apart. I think I'll use the timer out of a microwave to run the whole thing. Most have a control relay to put power on the clystron, so it wouldn't be a big stretch. I can get a used microwave at Goodwill for about 20 bucks.

Probably an electrical supply of some sort. That kind of stuff is pretty standard. If I need to, I'll make my own. JT

Geez. I just looked on ebay. You can get 5 of those lamps for less than $8. I can definitely afford this. Looks like I might be getting into this sooner than I thought. I do a lot of pet memorials and being able to do halftones would be a big help. This is certainly cheaper than a laser engraver.

Yeah, you can get an old flatbed scanner for 10 bucks or less at Goodwill. I think I'm gonna go that route when I get around to doing this. I'm in the process of moving to a new venue with my design station. Out of the house. Yeah! That looks like the best route to me. I'll be accumulating parts, little by little. JT

I'm really interested in your cabinet. As for the gun, like I said in an earlier post, I switched to a Clemco knockoff and a foot pedal valve. I modified the air jet to accept orifices of different diameters as needed. Most of the time I blast with a 1/16" air jet and a 1/8" boron carbide nozzle. I was having control problems too, mostly related to the fact that my compressor couldn't keep up with the old gun because the orifice was too big. The pressure kept fluctuating, changing the rate of cut. Kind of like trying to bowl with a ball that keeps changing it's weight. I've been wondering if it would be possible to use a siphon gun with a pressure pot, only applying pressure to the pot when applying pressure to the gun. JT

Wow! That's an old flatbed scanner cabinet, right? What are the bulbs? See, I priced the stuff at Rayzist. It's really high quality equipment, well built. That being said, I'm retired (code for broke) so I have to build most of what I use. This looks like the real deal to me. JT

I second the motion. I think we could all learn a thing or two. Could we see your Rayzist setup too? JT

Wow! Jump on that puppy! Somethin' tells me you're gonna be doing a lot of decals........ JT

Nice. I have the cheapo floor model from HF. I had to weld up legs to replace the flimsy ones that came with it. SiC is heavy. I changed the gun to a Clemco knockoff and put in a foot valve. I also added an air jet under the siphon pickup tube so when I press the foot valve, air floats the abrasive. It improved the grit flow. Silicon carbide has sharp edges that make it lock together. The air jet breaks it up. My dust removal is based on an old Kirby vacuum and a homemade cyclone. I'm planning to make a better blast cabinet, based on one of those 275 gallon bulk tanks. I want it to have two doors and also open like a clam. Next summer. Too cold right now. JT P.S. I like the razorback mirror.

Man, that's just beautiful. I'm gonna have to try the Rayzist. I use a siphon rig, so I'm running at about 80 psi through a 1/8" nozzle. Do you think Razist would stand up? BTW, what kind of gun do you use?

Eazy, that's really nice work. Tell us about your equipment. JT

That's really beautiful. What kind of gun are you using? From the pressures you mentioned, it sounds like a pressure fed one. I find the rayzist interesting, but I just don't have the setup. I'm not sure how it would work on stone, anyway, but the glass! Wow! How hard is it to work with? JT

Yowzah! Nice work, Bob. Tell us more about your techniques. What resist do you use? Are you using ALOX or SiC blast media? JT

One of my gripes with Sign Go is the paucity of tutorials and good helps. Since I have the lite version, I don't get updates. Many of the helps aren't very helpful in the lite version, probably improved in the full blown version. Again, it would be really nice if the SG folks produced some tutorials on youtube. Most of the stuff I've learned, I've learned by burning at the keyboard for hours. JT

Wow! Nice. That red really pops. What did you use for resist, both for the etch and the cut in the back? JT

Nice work. That's a mirror? Did you cut the shape? JT
