Bill,<br><br>I think you'll have to make a new one; I've made and tested about a dozen so far (Scouts; I actually hovered while they followed my instructions). The best hole-maker I've used so far is a pin vise holding a stub of a fairly small needle (I can mic one if it's important). I used CAD to lay out the holes (cut the disk out of the paper and punched the can thru the paper). A very light hammer (4 oz or less) and three hands... one guy holds the can and the pinvise and the second guy taps the pin vise with the hammer when asked. Another advantage of using a needle is that you control the direction (angles) of the jets fairly well as opposed to a drilled hole - and if the jet is not exactly where you want it, you can "tweak" it by re-inserting the needle and angling the hole (bend it).<br><br>Also, a bit of aluminum flashing makes a great windscreen and kicks the efficiency up another notch. I bend the ends so they can interlock (grip the fingers together on your hands, palms facing each other - like that). The pots nestle down about 3/4 of the way inside the windscreens the way I do them.<br><br>IIRC, I modeled these after the Photon stove (what a coincidental name...). I did make one of the pearlite filled ones and it worked fine, but the photon-style are nicer IMHO. My boys and I made about 4 variations of number and placement of jets - they all work about the same (not quite - we can time boil and burn-duration differences) - you may as well enjoy the experimenting for yourself <grin>.<br><br>Did you use my oven-cure tip for the J-B Weld? I am not patient enough to wait 15 hours...<br><br>Tom
