UVC (wavelength ~254nm) is very effective at killing bacteria, yeast, etc. fairly quickly. A wand like below could probably be used if you are having contamination issues, but diluted bleach would probably be easier. http://www.amazon.com/dp/B0018A330K/?tag=skimlinks_replacement-20

has worked really well for me so far. comes in a nice little case with the buffers. also replacement electrodes aren't too expensive

i would definitely recommend woodstock inn if possible to make it there. also, the strange brew in manchester has a pretty good selection of beers. i would make sure to try the harpoon IPA, also both shipyard and long trail are worth trying while in the area

tubing cutter worked well for me

one thing i've seen for cutting balsa wood is to file the edges of a copper pipe really sharp, put it into a drill press and use high speed. might work for rubber too?

i would be careful ordering anything from that place. i had to go through my bank to cancel an order there, and there were a few other similar complaints with the better business bureau i found.

Distilled water has no mineral content, but I don't believe that distilled water is marketed as sterile. You can buy sterile water but it will probably be insanely expensive and is usually only used in dialysis, operating rooms, etc... Sterile just means that it is completely free of microbes...

I noticed the same problem when I first started using one. I put a dish towel in between the lid where it closes (near the handle). This seemed to be the place that steam was coming out most. With preheating there is no problem holding temperature for an hour.

The real beauty of a Peltier junction is that all you need to change from heating to cooling is to switch the current direction. As far as my...

I used two different sizes on my keggle, worked great

This may be slightly off-topic, but if you happen to know anyone who works at a sheetmetal shop or even machine shop, ask them if they have a set of knockouts, GB ELECTRICAL KOS-750B "SLUG-OUT" KNOCKOUT SET PUNCH 3/4". They will cut a nice clean hole on-center with minimum deburring required.

For 2 dollars more, I'm considering buying some MMC p/n 9241T422 to try. With 12"X24" you can fold it over and get more surface area, as well as only having to sew together 3 sides.
