I'm doing it on a rough cut(triangular) piece. I tried a hand drill and Dremmel, though a Dremmel is probably too fast? Lots and lots of water and the drill bit didn't seem to do much of anything. Maybe I need to find a high speed bit that'll work in a Dremmel?
I bought two Dewalt split point cobalt drill bits and they didn't work worth a damn. I usually don't drill through too many metals or anything ceramic so maybe I'm a bit tool dumb here...but is there different types of cobalt bits...
Don't think there's any issues with quick temp change. You can get the stone white hot with a torch then plung in cold water w/o a change. Curious if it wicks better than SS when its cold though.

Dan - Did you say you were using cobalt drill bits on this material? The only bit I had of that size was a cheepo 'titanium plated' bit. After that first wick the tip is rounded off so looks like a trip to Lowes is in my future.
Anyone find a good durable cutting wheel for these stones? My second wheel is about to go after only making 4-5 wicks. First one was a no-go from the start.
Just made one and have to say it was a synch compared to wrapping the coil around the wick. Now I just need to get the wick installed without breaking it lol. I found that the old white stir straws form the 'straw mods' worked great for pushing the coil off of the bit inside the hole.
Edit...
I know I just repeated it twice this AM...damn frustrating to get to the end and have it snap so easily. Think I'm going to give the through hole a shot after work. Looks like it'd be less likely to have an issue breaking.
Cut stone....meticulously grind stone to an 1/8" cylindrical wick....boil wick for 5 minutes...fire wick...cool wick...fire wick...cool wick...place wick in PV...wrap wick with resistance wire..tighten...tighten a little more...Small gap...tighten a little more...snap $*&%¡!
Didn't mean to imply fish sticks were not safe, or that a safe filter would still be safe when you heat it up. But since we still don't know the exact materials used for these TopFin bubble stones I thought it was an interesting alternative to consider.
Has anyone looked into porous ceramic specifically designed for filtering water for human consumption? Wondering if it'd be any safer?

Drilled out the DUD wick to 1/9 and made my first wick. Place in cup and filled with boiling water, torched with butane lighter (HD out of Mapp tanks for Bernzomatic). Pushed the wick in a hair too far and it snapped when it touched the bottom of the tank. Would my luck have it that it snapped...
Here are the stones I have. As far as I know they are the correct stones. The one on the left is a medium size, small on the right. Both are 'Fine Bubble Air Stone'. Hope this helps clarify.
I understand from the old co-op discussions that SS is a headache to work with, but how difficult do you think it would it be for me to cut through the vapor chamber base of a SGv3? I have a a spare SGv3 body laying around and was wondering if it'd be feasible to connect the fill hole with the...
Mine was soaked and I sprayed it after some cutting. I think that wheel was too thin. Tried another one in the set and it cut the stone like butter.
Made one wick then broke it during firing. Way under estimated how thin these need to be, at least in this stock DUD. Will try again tomorrow.
I think I need to get a different diamond wheel. Tried one of these and it worked for about half the first cut, but the diamond is only on the two faces so it stops cutting quick.

If a coil removes too much material I wonder if a couple diagonal slits cut in to two sides would provide more contact area while not over-weakening the wick? It would make wrapping the resistance coil a bit more tedious, but shouldn't be too hard.
My diamond wheels should be in today :rickroll:
