If you can get it, use 316. It's designed for high temperature use.

Re: Thermocouple
Thermocouples don't wear out, but they can be damaged. If there's no evidence of physical damage, like a crack or severe bend, and the temperature reads properly at room temperature with an upward trend as the kiln heats up, it's unlikely to be your problem. Did you verify that all of your elements ...

Re: Kiln Relays
That's great to hear. I've said it before, but I think solid state relays are the way to go.

Re: scratch and wet belt sander
Where did the scratch come from? Most scratches don't survive a fuse firing.
Is there a ridge in your shelf or kilnwash? You don't want to refire only to discover the scratch has moved to a different spot.

Re: Blaster Question
Having a strong vacuum is great, but if there isn't good airflow through the cabinet, you'll never clear the cloud of dust that is created every time you blast a piece of glass. Add a vent in the cabinet in the wall opposite the dust collector. Mine is in the back wall and it's just a 3" diamet...

Re: Blaster Question
Jim, I have similar experience to Rick. Be prepared to change the hoses and add a pressure regulator and water trap at the inlet before you use it. Otherwise, it'll work fine.
Good luck.

Re: Kiln Relays
Got it, makes sense. I have a little Olympic SQ146GFE which is 115VAC, rated at 16A. Bought it new and certainly over 75-80 firings. So may need to replace those relays. The other kiln is an Olympic GF314ETLC which I bought "reconditioned". It had definitely been used but was in great sha...

Re: Setting up a Sandblaster - Compressor Size
I'm glad to hear your system is up and running. The HF cabinet is really a pain to assemble, but you did it right by sealing every seam. I've always rinsed under running water while rubbing the surface with my fingers. You have to remove the dust to avoid getting a haze after refiring, and I've neve...

Thanks Tony, Bert, this make sense. I don't really have a good location to pull high current wiring for an SSR to a wall or other remote location where cooling can be managed away from the kiln. What's my next best option? I hear about mercury relays, or would it be smarter to just upgrade the curr...

Re: Kiln Relays
I've been following this thread with interest and am puzzled (again, it happens a lot). If a relay is rated for 200K cycles and that equates to less than 100 relatively short, 6 hr firings I assume that many of us run these mechanical relays waaaaay past their rated life. Is this rating artificiall...

Re: Setting up a Sandblaster - Compressor Size
Just to be clear Joyce, the only way you can use a pancake compressor is with a pressure pot (not a siphon blaster), and lots of patience. It's best if you have small pieces to blast.

Re: Setting up a sandblaster
Hi Cynthia. My recommendation for a pressure pot system is everything above, plus a Glastar 100B-S. http://www.glastar.com/catalog/sandblas ... asters.cfm
It's an easy add-on and it uses a fraction of the air a siphon system uses.

I periodically get emails about setting up a sandblaster, and it thought it would be helpful to others if I shared my response here as well. The question centered around placing a sandblasting cabinet outdoors in South Florida. There's no reason that you can't have a sandblaster on a covered porch o...

Indeed, Robax is a glass ceramic matrix, and not a borosilicate.
