Black iron pipe will rust inside with compressed air. If the air is dry, it will only flash rust, but if no dryer is in the system, condensate will cause thicker flaking rust. As long as you put a...

Chris, I searched this discussion and the only mention of plastic is from you. I think all of the previous posters have spoken only of PVC pipe. Plastic is as generic of a term as metal. I don't...

This shop did it the cheapest way possible. The problem in a commercial shop is the liability of a worker getting hurt. Not such a worry in a home shop.

Time frame depends on many variables. ...

The chart you reference is not a rating chart, only a typical application chart. That is why the statement on page nine says to consult the rating charts to determine suitability for compressed air....

Mike,

There are two issues with PVC in compressed air applications:


PVC is pressure rated for non-compressible fluids only(i.e. liquids - water, fruit juice, etc.) It is not pressure rated...

Using a safety concern in this instance is a specious argument.


black iron is stronger
stainless steel is stronger/more expensive
nickel alloy pipe is tremendously strong/very expensive

Bill,

Type K & L are shown there because there working pressures are sufficient through all size ranges up through 10" tubing. We are talking about 1" and under tube here. That is why the quote...

Bill, I hate to disagree with you, but per the Copper Development Council's own Copper Tube Handbook, it states:
Compressed Air—Use copper
tube of Types K, L or M determined by
the rated internal...

Unless you are running 1" line or over, or if you are running 175psi in the line, I would feel safe using either. Regulate the pressure going into the header, and you should be around 100-115psi in...

Predrying air to a compressor is used typically not to prevent moisture after the dryer, but to increase inlet air density in order to increase compressor efficiency. Interestingly enough, moisture...

I think what Jim is referring to is a single stage compressor versus a two-stage compressor. Both are made in the US (Campbellsville, KY). The single stage compressor makes more air than the...

Randal,

I think I have found one. However, making one could be fun, so i may try it either way. Thanks for the advice.

Maury - wondering if he has ever seen a stop sign on Ebay........:p

:rolleyes:Umm.......I don't really have a use for it Bill...........But it's FREE!:D

Actually, I have wanted one for crosscut dadoes in bookshelves and to crosscut wider boards than my 10" CMS...

I have and opportunity to aquire a Delta 12" RA Saw model 33-892 for free.:D However, the saw is missing the blade guard. I have looked online at dewaltservicenet and the part is over $350!:eek:

Only 2 months old to me, but mine is a 1954 Unisaw with a new Bies 30" fence.

53 years old by my math.......

Just came across these looking through some old pictures. These are a couple of PVC air lines that exploded in a shop I visited. They had already repaired the lines with new PVC. Luckily, no one...

This is a single stage compressor although is has two heads. Each one compresses from 0psig up to 135psig in one stroke.

The pressure switch is crappy from the start. I would replace with a...

I came back to this thread tonight and was shocked to find advocates for using PVC on compressed air lines.
I have personally seen the damage caused by an exploding PVC line. These were not caused...

Dale,

I work in the air compressor industry. Copper is absolutely acceptable, and in some ways, preferrable for compressed air lines.
I would typically suggest 3/4" unless the cost is way over...

Got it home yesterday. Had to take the top off to make it light enough to put in the shop. Looked inside and no cracks in the trunions - Yeah! (pics below)

Anyway, the tilt and height wheels were...

After looking around for a some time for a PM 66 cabinet saw, tomorrow I'll be bringing this baby home!:D

She needs some cosmetic work, but otherwise in good condition. I will be detailing my...

Thanks for the input guys!

I went the other day to see the Jet 18" band saw up close and fell in love w/ the SC 18". I was thinking the band saw would serve for some of the table saw operations,...

I hope you guys can help me on this decision.....:rolleyes:

I am looking at upgrading either my band saw or my table saw. My band saw is a Delta 14" 3/4HP with a 6" riser, and the table saw is a...

David,

The loss I am referring to here is pressure loss, not air leakage. The flow of air through the restrictions(regulator, hose fittings, etc) will cause a pressure loss through them. Think...

David,
If you are running the regulator at 40 psi, it only affects the use rate of the gun. If the gun is rated at 8 cfm @ 40psi, then the use rate is 8cfm. If the gun is rated at 8cfm @115psi,...
