A 2" potato cannon.
With the proper propellant and ignition system, range was about 250 yds...S

After you construct said potato cannon, be sure to visit http://www.geocities.com/Yosemite/Rapids/1489/

You guys obviously like to have more fun with your EMT than I do . Personally, I use it for building speaker stands and lighting stands.

The potato cannon sounds cool...

Potato cannons (aka spud guns) are great!!!

Mine is 4"PVC necked down to 1 1/2" for the barrell. I'm not sureexactly how much range I get, but if you shoot it straight up you lose sight of it!!!

I've used pvc to construct a frame for my indeterminate cherry tomato plants that grew beyond 8' tall. I used 3 pipes vertically with several cross-members and gave them something to grow through and extra support by wiring chicken wire to it. I pound rebar down into the ground to add some stability for the vertical supports and slide them over the rebar.

I also use 3' sections of pvc drilled with 3/8" holes 8" from one end and capped at that end to plant down in the ground near the roots of my tomato plants (done at the same time as I'm planting the plants) so I can water the roots fully and get more produce out of them.

I just bought a roller to do some of that fancy-schmancy decorative painting - rolled rag was the design name/technique. I thought the pre-fab roller would make it go faster than wadding up fabric and rolling it across the wet paint and boy was it! When I cleaned the roller I found that it was a roller-length chunk of 2" pvc covered with a tube sewn from a 12"x10" piece of t-shirt material that was kind of wadded and twisted around the pvc and held in place with roller end caps inserted to keep the fabric in place. See http://doityourself.com/store/1786128x3.htm for similar item. Very clever and durable compared to the cardboard tubes used in some paint rollers.

My buddy used some scrap sprinkler pipe and welded himself a sand rail. He used 3/4" emt for the cross bars.



He also built his kids a peddle bicycle rail out of 1/2" emt.

Dude, where's my asprin?

There is a local lumberyard that sells EMT as part of a playground set for kids. It's used as a fireman's pole.

Also, used to know of a company that made portable garages using EMT with special short set screw fittings they bought somewhere on the internet. No bends, elbows or LBs for them.

Know a guy who plays didgeridoo on all kinds of pipes. 8' piece of 1 1/2" pipe sounded real great, something like a small propeller plane. Vacuum cleaner hose looked pretty weird.

I work at a PVC pipe factory; water/sewer, electrical, well casing, etc.
I have heard some incredible things.
We have one 'line' that turns 1 1/2" - 2" duct out for a company that makes furniture. We just don't put a bell and writing on it.

The guy that fixes our cranes took a piece of 48" x 20' 'scrap' water pipe. 150psi, 3/4" wall, $2500USD (if it was 'good pipe').
He made a swimming pool slide for his kids.

Or value of 'scrap' is $.05/lb. That pipe weighed 2500lb, he took a bunch of money off our bill, and delivered it himself!
