I'm over to "the Kid's" place tommorrow. We're moving the air
compressor to his basement and setting up scaffold for sandblasting
the whole exterior of the house. He just found 100' of 3/8 line
restricts the blaster too much.

His question, what should be used for temporary large ID air line?

Karl, when we were blasting the paint off'n Swift boats in RVN, we used
1" line for anything up to the blaster rig itself. Then, whatever sized
lines it had.

It's not "safe" for shop piping, but sch-40 pvc is rated higher than
you'll be using it.

I've done that a few times to get air 200-300 feet away for a job like
blasting my gate posts clean.

You can probably rent larger air line from United, Nations or other
equipment rental places that rent trailer type compressors at a
reasonable rate. You might find renting larger blast equipment is
practical as well if it saves a lot of time and labor. Otherwise a roll
of 1/2" or 3/4" PEX tubing and a couple fittings should work, and be
useful for redeployment later as water plumbing.

3/4" garden hose?

It's not rated for air *at all*. No need for "scare" quotes - it's not
safe for use with air, unless it's completely contained in ground or a
shatter shield. Fundamentally different things happen when a plastic
pipe containing 100PSI water and one containing 100PSI air crack. One
results in shrapnel.

Large diameter rubber air compressor hose (as seen on a jackhammer hear
you) - as already mentioned, it can be rented from the same places that
rent towed compressors and jackhammers. Or you might find a roll at an
auction.

Please don't feed the trolls. Killfile and ignore them so they will go away.

Use a couple T, and run parallel dual lines.

Garden hose might work, if it's heavy duty stuff.

Yes, Nanny. I won't do that anymore.

A rough calc for 100' of line and 20 cfm gives a pressure drop of 48 psi for
..5" id, 5.6 psi for .75" id, and 1.2 psi for 1" id - diameter is your FRIEND
:-).

The commercial ones are bigger. Reminds me of doing a Casino pool and
had to hear about three sand blasters in their huge "courtyard" for a
week or more. I can still imagine the shriek.

I have a blue one with stainless connectors...

Sounds workable. I'd want to use good quality hose.
