That was the load speed of the motor cranking the pump but not sure exactly the psi in the tank when it was measured. I’m using a propeller tach from my rc airplanes. I could hook up my magnetic tach from my lathe and confirm my numbers. I’ll order another pulley if it’s still reading too...

Just got my compressor build almost finished up. I am using the HF 5 hp two stage compressor pump with a marathon 26.2 amp 1750rpm motor. The compressor’s rated rpm is 1180. I ordered a pulley for the motor to get it as close to the 1180rpm, wanting as much CFM as I could get out of it and I...

Slackdaddy1, I was considering that also. Was looking at taking one 180 loop off of the middle of the cooler and running two parallel lines through it but worried that they might be silver soldered and I’d ruin it trying to get it apart. I figure there is about 15 feet of the 3/8” ID tube with...

Flipping won’t work, but I did make a mistake in my drawing. There is only 4 upward loops. The rest are down.

I’m putting together a compressor and was going to use the common Derale 15300 with my own fan attached. After receiving my cooler, I noticed that the piping in the cooler makes 8 loops upward throughout the flow of the cooler. It would be standard practice to have the tubing all running in a...

You would have really liked seeing it at 78rpms then. I pulleyed it down to a nice 40 rpm and it worked perfectly. I used the old bearings out of the compressor motor for the ends. They happened to be just about right size for the 3/4” and 1” pipes that went in the ends. A quick lick in the...

I agree with failing pressure switches and relief valves causing catastrophic failures. Something I just started doing with my current compressor is turning the switch on when using and off again when I roll up the hose. I have just always left it on before but no reason too as the tank with the...

Photos of tank.

Update: I found a tank for 25.00 and spent another 20 to go pick it up. It was an old (1969) Ingersoll-Rand tank calculated to about 80 gallon size. The outside looked decent so I got it home and hydro tested it. It is rated for 200 and so I took it to 300 and it held over night. No leaks...

Ok I’m hearing more storage. I’m still limited to 130psi max in the tank or tanks if I get another tank to add to it. My old pump now takes about 10-13 minutes to fill the 60 gallon tank from 35psi to 120 psi. Then it shuts off. I open the valve and the air rushes out and the pump starts again...

Larry-g, I have had my eyes open for a used tank for a while now. Can’t seem to find one at the bargain price for a once a year use. The only place I have to put the extra tank when not using it would be outside. Not sure how long it would last out in the weather. I did think I could mount it...

I just took a look at surplus center and it looks like it has some pumps that would fit the air supply demand but is quite a bit outside of my price point budget. If I wait for the right coupon from HF then I can get that one for around 200.00 or get the generic one with 22 CFM single stage for...

BillK, I set the regulator to 50 psi when blowing out the sprinkler lines. To much more and I risk blowing a sprinkler valve. I use a 75’ - 3/4” garden hose to go from the compressor to the waterlines. I have up to 7 sprinkler heads each line that are 3-4 gallons a minute with water but with air...

I currently have an older Coleman Powermate 230v 15 amp 60 gallon tank single stage compressor. I have 75-100feet of 3/4 hose with high flow quick connectors on it. I use it for general garage stuff including impact gun , tire fill, blowing air, very rarely sand blasting and to blow out my...
