drilling holes in crucibles?

[Geoff Lee]

My girlfriend wants to use my old crucibles for planters in her garden. To avoid mosquito infestation, we need to drill holes. What would you recommend to drill through the bottom of an E.C. crucible and about 1" of glass.

Doesn't need to be pretty, but want to do it right the first time.

Masonry bit with a hammer drill and right at the glass line. Half inch and about four of them should do.

.410 ?

[Geoff Lee]

Cool, she'll be happy to know that will work. Thanks for the help. On a side note, only 2 more days of using the f@$king EZTherm! the Stadelman is on the island, will be delivered on Monday we're going to working out of it soon.

Make a movie of how you dispose of it and put it on utube. Be imaginative. Remember the exploding whale.

Geoff, could you get Steve and Eddie in the same room together while they were both there?

i have used diamond core drills to do very clean small holes in crucibles. Put water in the crucible up to where the holes will be drilled and bore through from inside. Best to use and air driven drill by the way.

Don't know if you were there for it, but the first research recuperated furnace I built used one crucible turned upside down on another and drilled for door, burner and exhaust. Ipsen donated to the school some cracked crucibles for experimentation shipped along with an order. Concrete Coring Company sent a guy to core drill a 10" hole and two 4" holes while they were doing construction work on campus. Took about 15 minutes total as I remember.

If anyone knows a crucible supplier who would send defective crucibles for the cost of shipping, it is a very efficient construction method. Of course use a good crucible (that you pay for) for the glass container.

Hugh, I would probably be quite willing to do that in exchange for total handholding in showing me how to build a bio fuel furnace burner system with recuperation in my new shop. Electricity and propane are seriously expensive up here, almost like the big island.

[Geoff Lee]

Would have been cool to have those guys in the same room, but alas, just took Eddie to the airport and Steve is sending one of his assistants.

As for the old furnace, I'm taking measurements now to se if it will fit in my dumpster.

too bad you don't have a catapult nearby.

[Greg Frankhouser]

Umm, Maybe you know this, but the first time I saw it, I went DOOHHH.

Don't drill through all that glass etc, just drill through the SIDE of the crucible.

It will now drain etc.

OR use those crucibles as Lotus planters and keep the water in....

Hey Pete, you are up there close to Studio Potter LaLa land.

If you drop back 20-30 years, I'm betting that the Waste oil drip plate Kiln tech would work for bio-diesel.

I'm guessing that 90% of why we blow with gas, is the fact that the supply is RELIABLE, and we don't have to pay Churls to feed wood into the fire.

You have wood up there, dontcha?

hundreds of acres of it. I cut 20 cords a year for the house. I would rather get frying oil from restaurants or brand new oil at Sams.
