Electric and air learning resources.

I have two tasks I need to bone up my handy dude skills for.  Anyone have advice or can point me somewhere informative?

• Hard "master" air run from my screw compressor/chiller to feed: a 6/8 all air Gauntlet, Anatol manual with air clamps, roller master, screen room and assorted drops for air tools where desired. Open to black iron or fancier stuff but want to get my tubing diameter correct and install drain/drops appropriately.
• Replacing U shaped finstrip heaters on my electric dryer.  According to the panel 4 are out.  How can I use a multimeter to determine which 4 are bad?

Here's a good tutorial for multi-meter usage. The section on resistance testing starts around 2:20:

THE BEST Multimeter tutorial (HD)

The heater element should probably read between 10-30 ohms resistance (for a 240 volt element).... use a good element as a reference. You'll probably need to disconnect the elements to get accurate readings. It's pretty common to find the connection is bad at the element... and the element is still OK.

Great video, thx.

I did test for continuity on the six elements last I crawled in there to get the OEM part number. Bolted to their plate and wired up they all tested the same, at about 1 if I remember correctly. I'll pull them all to check when the new ones are in.

Don't know if they still do it but my old McMaster Carr and Granger catalogs had breif tutorials on some of this. I remember it had a tremendous section on lighting that help me build our color matching booth. And of course M&R can steer you right on air. We use hard steel.

Give me a call and I can help you out with both.

Will do Rich. 

Anyone use a rapid air type system for this?  That stuff is insanely overpriced with the fittings but looks like an easy install.  I only have maybe 50' of main runs/drops and another 20-30' of this and that.  Don't want black iron for various reasons but mostly b/c I'd like to be able to make a quick and easy drop where I want it or make a run quickly rather than it being a big ordeal.
