I find Online Metal Supply a little less expensive. http://www.onlinemetalsupply.com/

Cut one end and make it into a hop filter for your boil kettle.

Two comments: I think you are soaking them a little long. I would go for a two hour soak. I don't think I would put the grains in the cloths dryer.

I think that is wishful thinking today. I grew up during the late 50's the early 60's. If I got into a fight, the worst that would happen was I would come home beaten up. Today, 11 and 12 year olds become involved in gun fights on the street. The age of innocence is over.

I don't know if they would be able to take a beer bottle. I am guessing that they can't to prevent someone from trying. How would you stop Minors from buying beer from a machine? I know they would be a nice conversation piece for a basement bar but I have no idea if the will take a beer bottle.

The money should not be too much of a stumbling block. My transducer solution would be about $10 to $12. Your challenge would be to get something working for less than that.

If you think thats the case lets see you build one that is stable and costs next to nothing. You have made many claims in this thread. Lets see some results. IMHO the least expensive and most accurate way is with a $5.00 Freescale pressure sensor, a 9 volt battery, two $0.15, 1/4 watt resistors...

That part will not be likely to work as the noise of that part is too high. It is a general purpose op amp. The AD624 from Analog Devices would be a wiser choice.

Gravity does indeed change with altitude but the difference is very, very small. The gravitational force above the Earth's surface is proportional to 1/R2, where R is your distance from the center of the Earth. The radius of the Earth at the equator is 6,378 kilometers, so let's say you were on...

The problem with the float and potentiometer is that the system is very prone to water surface disturbances. Any slight disruption in the water's surface will cause the reading to fluctuate because the float will move. A slight movement of the float can cause large errors. Measuring the pressure...

The barley crusher is only designed for direct coupling. It can not take the side force of using a pully or sprocket. You will sure wear out the bearings prematurely.

Don't use a vegetable oil to lubricate it if you try it. The oil will go rancid and your grain will end up stinking to high heaven.

At 40 in-lbs it's kinda lite in the torque department.

Nothing PVC in my boil. I use the Lil' Sparky paint strainer, hop spider type thingy except I use a Polyester 100 micron water filter bag which is rated to 280*F and add 10% more hops to compensate for loss of hop flavor and aroma. I have had only positive effects from anything leaching from the...

Lil' Sparky has another build thread on here that he did a few years ago.

Chitcan the oil pump. Even a minute amount of oil will ruin your batch of beer. Have a look at this pump: http://www.amazon.com/dp/B0002HFTK2/?tag=skimlinks_replacement-20. There are many other pumps out there at less than $20, and that is less than the ingredients cost to replace an oil ruined...

I use AutoCAD. It is very powerful but costs a pretty penny.

What has been the modification of your DIY Malting? Are they fully modified so you don't need rests?

You can buy it directly from AutoDesk. AutoCad LT is sufficient for your needs and it is $1375.
