I use appropriately-sized hole saws in a Bridgeport. I've made a lot
of "stuff" out of conduit. The little Lincoln SP125+ MIG box is
great for this.

A standard tubing notcher will work fine.
http://www.harborfreight.com/cpi/cta...emnumber=42324
You will need suitable sized hole saws

A few caveats:
-conduit is designed to be easily bent. It is very ductile and has a
very low yield value. These are not attributes you will want for things
like go kart fames, hanger hooks, and similar.
-the OD on the sizes you mentioned are really pretty weird. Conduit
bender dies will work but not pipe dies. Not to mention clamps, mills,
hole saws are all the wrong size.
-Conduit has a relatively high ratio of unwanted zinc to weldable steel.
The wall is too thin to just crank up the heat and burn through the zinc
so you need to remove it. I just keep a glass jar with about 1" of HCL,
dip the end in for about 60 seconds, takes off just the right amount to
get a good weld.

Actually I think conduit makes great hanger hooks for the right stuff. I
have a bunch of them 1/2" with 180 degree bends. I made them using a
regular conduit bender and then I mashed the long stub end flat in my
hydraulic press, drill some holes in them, and screwed them to the front of
my shelves. They work good for hanging extension cords, large coils of
rope, metalic and liquitite flex, smurf, and other bulky linear items like
that. I'll post some pictures if you want. Its crude, but very effective.
I have tons of stuff up off the floor in the shop with these. None of the
loads are super heavy, but some are not light. Think of a couple 75' 12ga
extension cords and a couple 40' double layer tow straps. I just wish I had
a nice rubber cap to glue on the open end.

P.S. The radius of bend is too big on the larger conduit for most places I
would want to put a material hanger hook.

Just as an aside. Many swap meet canopies are made with special screw
connectors and conduit. I forget if its 3/4 or 1" I can post some pics of
those too. The connectors. I'ld have to wait until swap meet season to
take some pics of conduit canopies.

Anyway, yes the stuff is soft and easily workable, and definitely not for
structural anything...

I haven't seen one, unless something is made for another purpose and just
happens to fit the occasion.

I fishmouth all my tubing by angle cutting about 1/3 of the diameter away on
both sides, and touching the corners to a grinder to get a smooth radius.

You would use the same tubing nocher for thinwall round mild tube,
because that's all it is - BUT.

You have to grind, brush, file and/or pickle (with acid) the zinc
galvanizing off the EMT before you try to weld on it, and even then
you want to avoid the fumes - run a fume extractor on the welding
table, and/or have the breeze (or a fan) at your back, and/or use a
supplied-air respirator.

Inhale the vaporized zinc fumes while welding something galvanized
and Zinc Fume Fever willl mess you up but good.

Lowbucks is $325? Looks like it would do the job, though.

It's just where I could remember such things being sold so put it
forward. Whether you buy or copy the idea and adapt is another issue.
Looks easy to make, but like many things it comes down to the balance
between free time and paying time.

apologies, i know this is not what you asked...

wondering if there could be a way to rig up a jig(s) for use with a plasma
cutter? that is of course if you have a plasma cutter. i just remembered
seeing scenes from a tv show from the plant where they make harley davidson
motorcycles and they put the tubing in a computer controlled plasma cutter
machine that cuts the fishmouths (at varying angles). oh, i'm meaning, a
jig that you could rotate by hand, not some fancy computer controlled thing.
just wondering. the computer controlled one works beautifully.

just now i wondered if winmiter is still out there, googled it.
http://home.tallships.ca/mspencer/winmiter.html
makes a wrap around paper template even at varying angles.



b.w.

And also a poor choice for folding chairs and such -- which does
not keep people from making them that way. I've got some three-legged
and four-legged folding stools which have developed such problems, and I
need to redo them for supporting someone my weight. Probably water pipe
instead of conduit.

Hmm ... for one or two, have you looked at crutch tips available
at the local drugstore? I suspect that you can find some which fit.

Or -- go to someone like MSC, and look for rubber handgrips for
levers. They are available in various sizes and work quite well for
many things. And -- they come in larger quantities for a given price (I
forget whether it is ten or twelve per bag), so the price is likely to
be better than a "medical supply" (the crutch tips). :-)

Also, it won't do the 3/4" -- looks like 1" is the smallest

I find the fishmouth/miter template method of making EMT project
joints pretty quick (non-production that is) and easy. Just
print out the template, tape around the tube, and with a right-
angle grinder grind to the line. You can even make double
fishmouths to weld a tube at right angles to an X joint..think
patio umbrella stand. And these programs are.....free!

Problem is that conduit OD is an odd size
1/2" = .702"
3/4" = .922"
1" = 1.163"
http://home4c.com/conduit.htm

The soft vinyl caps will work since the stretch but the rigid
polyethylene ones are all in fractional inch sizes. Nothing matches up.

One option would be to lose weight! (ducking for cover)

Pipe is really terrible stuff to use for real projects. Try and find
some .083" wall tube.

3/4" conduit is .922" so it would probably work, might need a touch of
grinding.

What is the inside values ? Get an inner not an outer :-)

A valid suggestion.

That I may do -- if i can find some the right OD for the rest of
the hardware.

Thanks,

I tried that. Made a nice collar for the torch and a template/cam
tube to go around the pipe/tubing. I couldn't get the tubing to
rotate smoothly and had poor quality cuts. Would work OK for a 90deg.
cut but you can do that with a chop saw.
