I'm looking for a machinist that can make a few teflon and titanium parts on a lathe and milling machine. I have a top notch calorimeter up and running and have already done some experiments that didn't produce excess heat. I want to try some variations but need help with making the parts. I'm in the Boston Massachusetts area if anyone happens to be close by. Though they don't need to be close by because the parts can be shipped by mail.
My email is jeffd3@gmail.com (I might miss a message sent to jeffd3@gmail.com if it is sent months from now, so post a response to this message here on overunity.com and I'll see that)
thanks

Here is a quick description of the experiment.
Cell is 4.5 inch OD, 15 inch long PVC pipe filled with distilled water and potassium hydroxide. Two layers of aluminum wire .040 inch diameter surrounds the PVC pipe. Ten insulated thermocouples are between this aluminum wire and the PVC pipe. Power output is determined based on these thermocouples and temperature/power calibration curves. Power is 200 V DC at 1 amp.
Anode is approximately 5 feet of Gold wire and 5 feet Platinum wire (both .010 inch diameter) wound in a ring shape, about 1.8 inch diameter. Cathode is .040 inch tungsten covered with ceramic tube (.100 inch OD) so that only 0.100 inch of the tip is exposed.
