I've used a tool like this to remove the ferrules from 1/2" copper pipe (for regular plumbing) - works well for that...

You can learn to do anything on your own, just depends on how much work you are willing to put into it (and how easily you can pick stuff up by reading vs demonstration). I TIG'd mine, but that was more a function of having access to a TIG and not a MIG at the time. I hadn't done too much...

several years down the road on my mild steel frame....still unpainted, still in good shape. For the most part it's developed a patina and is in pretty good shape. I switched to electric along the way so not dealing with the heat from the flames anymore, but still get plenty spilled on it.

Cool, got it compiling - but I'm moving of course so everything is now packed up. Will try it out in a few weeks.

I've run into the same issue and have the referenced library installed. Any luck on it?

Depends on which part you're asking about? The insulation should work just fine. The aquarium chiller probably isn't big enough.

In general, yeast are tolerant of low pH environments, so acid based sanitizers can be less effective on them. This trait is sometimes used to "wash" yeast slurry of bacteria by adjusting the pH below what the bacteria survive, but not so low to kill the yeast off. Using a varied...

Bleach has a place, but you've got to be careful with it as it can degrade equipment if left on to long without dilution or applied to strong. The chlorine will react with metals and some plastics and rubbers. Pinholes and leaks in stainless are often the result of chlorine exposure. Chlorine...

the skinny line coming off the compressor should get hot to the touch assuming the compressor is running and the freon hasn't leaked out. If the compressor is only getting 'warm' to the touch, there probably is little to no gas left in it and it can't build up sufficient pressure to provide...

Depends on the beer, but under 10-14 days grain to glass is typical. 3-5 weeks for lagers. I can't hold my conicals below 45 for long periods, so it's better to just get the beer kegged off. If I gelatin them, they do clear up after an additional week, but otherwise, not a lot of change from...

Except for the really high end fridges, here's how they work: There is usually (not always) two knobs to control temp. The knob for the fridge portion contains the "thermostat" and turns the compressor on and off. setting it colder makes the compressor run more. The knob for the freezer...

Partial Mash is somewhat of an arbitrary term, but in practice is really used to describe an extract beer that gets part of it's fermentables through a mash, usually to use grains that can't be steeped and aren't available in extract form. The process typically only includes enough base grain...

I've got one on tap at home, although the initial try fits more as a Sour APA than IPA. Kettle soured, pH of 3.75 and 40 calc'd IBU, all through whirlpool. Lots of citrus fruit hops and fermented with WLP 644. OG around 1.050, FG about 1.010 I kept the pH and IBU a bit restrained to get a...

The plastic conical referenced is 16 gallons (and typically filled with about 15) I have worked with the 3 and 7 bbl plastic conicals as well - it's less of an issue there, but still have to be careful how everything is set up.

it depends on the ratio of volume of glycol in contact with the beer and the volume of beer. If you've got a large coil for the size of batch, then it can have a noticeable effect. On my conical with a 25ft stainless 3/8" coil, I notice that I get about .3 degrees of overshoot. My control...

Have you oiled it recently? When mine starts acting up like that it's a reminder to get the machine oil out after the brew finishes.

It may not be adding air (assuming everything is sealed tight) but rather pulling residual CO2 out of solution. Any restriction that induces a pressure drop (such as the prefilter) is a strong candidate for doing just that as the pump with pull suction. Assuming everything is sealed, there is...

I have a Berliner Weisse going right now - I hit it initially with Lacto culture'd up from grain + lacto delbrucki. In about 24hrs in the fermenter, dropped down to 3.3 (measured at around 110F), added WLP644 after 48hrs (still pH 3.3) checked again today (around 72 hrs) and it's quite fruity...

I have a utility line connected to the CO2 tank on my kegerator that I used to purge containers (growlers of beer, bottles of wine) with good success. If you're going for a few days to a week, seems to do well.
