    Put together a Quincy 325.... to Inflate Balloons.

    The pressure switch is adjustable, but the diaphragm is leaking. I am not sure if you can get repair parts for Square D pressure switches. Haven't looked into it yet. The relief valve is set to 200 psi. The tank is certified to 200 psi. I am SURE it is sufficient CFM for the pump...

    Put together a Quincy 325.... to Inflate Balloons.

    I'm sorry I didn't document the build process. I always forget to take pictures of what I am doing, I rarely have my phone on me out in the shop. As far as the tank, I scoured the internet and settled on this one: eBay Tank. It is a different model than the ones you get from compressor...

    Put together a Quincy 325.... to Inflate Balloons.

    I am under the impression the oil pressure in this pump is like an engine - as the bearings wear the clearances get larger and the oil pressure drops. Am I wrong to assume that?

    Franzinator, seems to work

    Do you have any links to building a franzinator? I have heard of them on this forum, but have not seen what is inside one.

    Put together a Quincy 325.... to Inflate Balloons.

    I'll be going out of town for a month next week. When I get back, I plan to pull the head and side cover. Hopefully I do not find any major issues. The oil pressure is at the high end of the gauge when running, so I figure the bearings must be good. Of course I have no idea what weight oil...

    It doesn't blow my finger off. The 325s have a crankcase breather that pipes into the inlet side of the pump. That pipe is in good condition. I haven't used it enough to measure oil consumption.

    We only use four. Two are back ups. All six at once and we have to open a window.

    Put together a Quincy 325.... to Inflate Balloons.

    It has some blow-by you can feel through the dipstick tube when you pull the dipstick out. I am not sure what the acceptable amount is. It also has some kind of odd high pitched noise that echoes through the tank when it starts loading up. I am hoping it is caused by the restriction in the...

    Stepped Compressor Speed with VFD?

    I recently got the compressor up and running. I have it in a separate room out in the detached garage/shop. I insulated the wall it is against with rock wool. Have not insulated or finished the other walls or ceiling yet. With the door to that room closed, it is very tolerable in the rest of...

    Put together a Quincy 325.... to Inflate Balloons.

    I picked up a used 325 on Marketplace, found the tank was rotten, bought a Manchester 80 gallon tank, and then plumbed the whole thing up. The motor is a good 5HP 3PH GE motor. I picked up a huangyang phase converter rather than a 1PH motor, as it was considerably cheaper and affords a few...

    Code on Panel Latch?

    Often enough to be irritated by the latch.

    Code on Panel Latch?

    I looked at using the OEM lock for the door. $60?! Generic locks of that style are $10. The catch side of the lock is unique to the panel, guess that justifies the extra $50. I think I'll keep it simple - remove the metal catch part on the latch and use a magnet to hold the door shut...

    Code on Panel Latch?

    I have a 100 amp Square D panel as a sub panel in my garage. I really hate that cheesy latch they all come with. Mine keeps jamming, I fiddle with it, it works a bit, then it jams again. Tired of monkeying with it. I would like to cut in a nicer latch. Is there anything in the code about...

    Air Compressor Pump Discharge Hose

    Lowe's by me has it on clearance for $2.54 for a 10' section. I'll grab one tonight on the way home from dinner. 10' will give me plenty to plumb in an after cooler some time down the road. At this point, I just need to get this thing up and running. I have WAY too much time and money...

    Air Compressor Pump Discharge Hose

    Appreciate it! I fit pipe on Navy ships and have a tendency to over do it, everything must be Mil-Spec. Literally. :lol:

    Soft Copper Tube Compression Fittings These items? I assume the bending would be done by wrapping around a cylindrical object of appropriate diameter?

    Air Compressor Pump Discharge Hose

    I do not want to use copper tube because I do not have the bender or flaring tool for 3/4". I have also heard of people having issues with the copper tubing cracking from vibration. Outlet temp of an air compressor is between 200-300 degrees Fahrenheit. Most hydraulic hoses are rated to 212...

    Air Compressor Pump Discharge Hose

    That is a fine solution. I am having trouble locating a quality hose though. Many people say to use a hydraulic hose, though they are not rated for the temperature.

    Air Compressor Pump Discharge Hose

    I have a Quincy 325 I am plumbing into a Manchester 80 gallon tank with top plate. The tank has a 1 1/4" FPT port for the pump discharge. The pump is 3/4 FPT. My plan is to use a 1 1/4" in tank check valve and a stainless braided PTFE hose. I am having trouble finding a source for a premade...
