I have a Quincy 325, powered by a 5HP 3PH motor, run off of a Huanyang 7.5kw VFD. I would like to install two pressure switches to have two speeds for the compressor. For 80% of my uses (home garage), the lowest speed the pump can turn is sufficient. My thought is to have one switch cut in at...

I picked up a Quincy 325 used on Facebook Marketplace. Finally got a VFD on it to see how it runs. The 1/4" OD tubing on from the tank to the unloader valve is leaking at each end, looks like it got banged around while moving it. Can I replace it with Type L 1/4" OD tubing and fittings from...

Hello all. I have a 30x40x12 garage I built about 5 years ago. Cinder block stem wall. 6" concrete slab. 2x6 studs balloon framed on gable ends. Scissor trusses. 7/16 OSB sheathing. 5/8 OSB roof deck. I'm in eastern NC, no real snow load to speak of. I built two rooms on the left hand...

I plan to install a receptacle for a new Chevy Bolt in the garage. I have a 40 amp circuit fed by 8/2 romex for my welding machine (which uses a NEMA 6-50). I would like to install a NEMA 14-50 receptacle tied into that circuit. I am sure the code answer is no (should be dedicated circuit...

I have two welding machines on a cart. I only use one at a time. I have an extension cord for plugging the machines in. I would like to put two 6-50R receptacles on the end of the cord, I am tired of unplugging one machine to use the other. I am looking for an elegant solution to make up a...

I recently bought a 5HP air compressor for my garage, with a rated amp draw of 20 amps or so. Garage is a 30x40x12 detached. I have a 90 amp service running into the garage to a panel. The panel is by the side door closest to the house. I plan to put the compressor on the wall opposite the...

I'm looking to install an air piping setup in the garage. I have a 5HP Quincy 325 - puts out 18CFM at 175 psi. Garage is 30x40. Home garage - one man shop with average air tools. Burr motor, needle gun, and sand blaster are about the biggest air hogs. Maxline's site recommended the 1/2"...

I have a Quincy 325 I would like to quiet down a bit. Installing the compressor outside is not an option at this point in time. The compressor is installed against the gable end wall of my shop. I am thinking about installing 1" PVC pipe up the wall, through the soffit to the outside, with...

Picked it up for $500. The tank is stamped 1959. The motor is a 5HP 3PH General Electric. It is obviously pieced together. The seller swears it runs good and was rebuilt a few years ago. I plan to inspect the tank with a camera through one of the 1 1/2" NPT plugs and then hydro the tank...

I was looking at Facebook marketplace and found a Quincy 325 for sale at a good price. Only rub is it has a 3PH motor on it. Anyone have a good source to get a quality motor for $500 or so? I found this one...

I have a 20 gallon direct drive compressor in my garage. It handles most work I do - impact tools and the like. But I have an air hoist hanging from the rafters for hoisting things into the loft that is an air hog. I can get two or three lifts out of the hoist before the tank is down below a...

So... We moved out to the country about 5 years ago. The house we bought had been vacant for about a year. The place was INVESTED with paper wasps. I have spent the last five years terminating these things. Have really knocked back their numbers. Found them behind the plastic shutters, on...

I am a home enthusiast with a few older vehicles to lube up. I bought a HF cheapie and it didn't last too long. It gave me plenty of grief along the way. I want to buy a nice one now. I have Dewalt 20v tools, so I am thinking about the DCGG571B. I also see LocknLube is another good choice...

I have a 30x40x12 garage with scissor trusses. I balloon framed the gable end walls to meet the wind code in my area. The framer put braces on the lower cord about 10' from each of the side walls. I would like to remove the lower cord braces on one side of the garage. My understanding is the...

So.... I have a dumb problem. When I built my shop about 5 years ago, I put a 6x7 roll up door on the back of the building for the lawn mower. I really hate that door, it's one of those storage unit type doors. I want to put in a regular sectional door. Problem is, 6x7 is a custom size. I...

I am building a 12x18 room in my 30x40 garage. The room has a ceiling at 9' and the building has 12' walls. I plan to insulate the room and heat it while using the room during the winter. One day I might condition the room year round, but that will not be for some time. I plan to insulate...

I am putting a storage loft in the garage, finally. I am unsure on my joists size. I am waffling between 2x10s and 2x12s. The span is 10' with joists on 16" centers. The planned load is 'heavy ****' - car parts and the like. I looked at the span tables and it looks like 2x10s are plenty...

I am building a 15x20 room in the corner of my 30x40 garage with a storage loft above. I would like to be able to store car parts and such up there. Question one - what load capacity should I shoot for? Second - which will be the best choice for joist material - solid wood, I-joists, or truss...

My compressor **** the bed a few minutes ago. I am looking at the QT-54. Better options? Quality unit? My budget is around $2k-$2500. I have a mild shop setup for personal use. Plan to get a plasma cutter at some point and maybe a sand blast cabinet.

I am in the planning stages of running about a mile of home network cabling. I plan to run Cat-6 throughout the house. There is a mechanical room all of the AV gear will be located in. There are three cables coming from the crawl - Cat-6 to garage, Cat-6 to shed, incoming ISP coax. The rest...
