Jerry, I've used that trick for over 20 years now. One other thing to consider. They make a detector for people with cooking skills such as mine. It has a button that disables the unit for a certain amount of time then resets. I saw this many years ago in a magazine. Somebody should invent one with ...

Don't know if this will work for you but when I need to take the detector down when I am cooking I put it on my pillow so it gets back up before I go to bed. If you have a place you're sure to go to after combing, put the detector there.

Do you have a link for Rainbow Glassworks?

A hood with positive air flow is much better than a respirator if you can afford it and don't mind being in a hood. My nose starts itching the moment I put a hood on. The filtration system is important to make sure you're not breathing any oil mist. Breathing air compressors and utility air compress...

Yep, the glass goes right down the drain. Total of less than 2 hours grinding time. I'll build a station that will serve my grinder, belt sander, and saw as soon as the new kiln is firing. Any day now I hope. Charlie, I dropped the ball on the lap but I have some ideas. I want to check out the feasi...

Phil, thank you for the reply on respirators. I did 5 years in a magnesium plant where you had a respirator in your posession at all times, chlorine. Then 20 in an oil refinery. Started in steel mills. So I've inhaled my share of bad things and worn my share of respirators. I was hoping to be done w...

A link? Why didn't *I* think of that? http://www.amprobe.com/cgi-bin/pdc/pgview.cgi?id=main&type=elec Sorry. I powered up my new kiln for testing yesterday. 36x60x12 inside. Room temp to 1600 in 55 minutes on 56 amps. I'm quite pleased. The outside only got warm to the touch. The Paragon ceramic...

A few months back there was a thread about electrical usage and metering. I came upon this site today and it has a fine selection of electrical items. the pages seem to load strangely, at least on my browser. After you click on the KWH Meter tab it says done and you have to scroll down to see anythi...

A: the center feed water works better than imersion. At high speeds water will not reach the center of the pad. Imersion works, just not as well.

Q: An earlier post mentioned a respirator. Do you find particulates are in the air when wet grinding?

Colin,

How do you make your crucibles? Did I miss that somewhere?

You might check with a rock shop. I've just never heard of a SiC pad if it's metal like the diamond ones. Not cost effective. I've worked with laps for many years as a machinist but the abrasives, whatever they were, were fed onto a cast iron plate. This thing you are talking about sounds like a SiC...

I can't tell you about SiC pads but a diamond belt that costs $500 is only $9 in SiC.

Carol, That sounds pretty much like what we were doing. At times when we had one of the large kilns completely full we had water dripping on the floor from the condensation. I just wasn't sure of the drying times on the fly. I'll try the schedule you mention and see how it works out for me. Thank yo...

I thought I posted this once but it didn't show up so here goes again. I took a 2 week casting class last year where we were using Gerry's Mold Mix. We fired in wet molds the whole time with no serious problems. How do others usually dry their molds? Does anyone in here fire wet molds? Thank you, Jack

Lani,

I know the costs of UL approval. To get one on my controllers would take the profit of the first 28 and the first seven per year in order to remain competitive.

It's a catch 22.

Anybody else think the BE fixture is insanely overpriced?

My solution is to find a fixture I like and make a mold to slump the same shape as the original glass. Then see if I can order just the fixtures from the manufacturer.

I see the BE fixture at $20 tops. Maybe they can explain this one.

Jack

Maybe that wheel missed one step in the manufacturing process. Or so that you can learn to drill a hole in the exact center. Go to the tool store and ask to see a demo of their centering head. It will look like a rule with a sliding vee thing on it. Very handy. Have them demo it on your felt wheel. ...

Ellen,

Do you have a good source for the polishing bullets? What abrasives do you use?

Thank you,

Jack

Tony, My sander does take a weird size for the glass world. I get my belts direct from Wilt in NY. SiC are around $9 each, Cork a little higher, and diamond much higher, $400-500 range. 6x48 is a common belt sander size for wood and metal sanders. The Wilt 6x48 sells for $2700 new and I got mine for...

I went to a lab glass place and bought a used Wilt 6x48. My first choice would have been Somaca. Wilt is much more expensive but I don't feel it is any better than Somaca.
