Gentlemen, I'm looking to add an air dryer in the shop and would appreciate suggestions and feedback on my proposed solution. Some background... I have a new Quincy 5 HP 80 gallon, 2 stage compressor. I'm looking to get dry air for my MQL (minimum quantity lubrication) system for my mill...

Gents, I'm looking to put a new vertical 2 stage compressor behind the shop to reduce the noise in the shop and free up some space. I haven't purchased the compressor yet, but it will probably be a Quincy QT5, 5 HP, 60 gallon unless I can find a great deal on a larger compressor. The main...

Hi, I'll be putting down the epoxy color coat in my garage late this afternoon. Last time, I ended up with lots of bubbles, perhaps due to air getting entrained in the epoxy during mixing. I probably should have waited until later in the afternoon as well. I have no reason to think that...

Hi, I am getting some information from the building department on grounding requirements that I don't understand and want to know if I am missing something. I have a 400 amp main panel on my detached shop. It has 2 200A main breakers that feed two subpanels, one inside the shop and one...

Greetings, I am looking for an air dryer and (longer term) a compressor for the shop. It will see intermittent use. I am mounting my compressor behind the shop in a small outbuilding for noise and space considerations. I have a 20 year old 5 horse, 30 gallon Craftsman compressor. I...

Hi, I am planning on adding a dust collector to my new shop for the woodworking tools. I am giving thought to mounting the dust collector outside for reasons of space and to (potentially) avoid the fine dust that might escape the filter. I'm located in the Bay Area, CA. The shop will be...

Greetings, I'd like to use a magnetic (or solid state) contactor to turn on/off my phase converter. The phase converter is rated for 100A at the input. It is always started and stopped without load. I am planning on a a couple of three-way switches to control voltage to the coil. I can get...

Greetings, I am looking at options for heating my new shop. The ceiling in the center is 13'. I live in the Bay Area in California. I'll keep the shop heated in winter to high 50's, to control humidity, all the time and to a higher temperature when I am working out there. Separated...

Greetings, I am building a 21x44 detached shop. The electrical drop goes to the meter main (320/400A) on the garage, with separate 200A breakers to the house and the subpanel in the shop. I am planning on heating with gas. Here's the question: Can the ground connection (1/0 Cu) to the cold...

Greetings, Looks like the slab is going to get poured either tomorrow or Thursday after a bunch of rain delays. I am planning on curing the concrete by covering it with burlap and keeping it wet for a week. The temps will be in the low 60s in the day, low 40s at night. 4500 PSI mix...

Greetings, I am getting ready to pour the slab for my new shop. It's an 8" slab on top of 15 mil Stegowrap. The concrete contractors were planning on tucking the vapor barrier under the felt expansion joint which is nailed to the stem wall. I talked to the Stegowrap guys and that suggested...

Hi, Getting ready to pour the slab -- 8" thick with two layers of bar over Stegowrap. The slab is floating. I have some questions I was hoping I could get some help on. 1. Location of the expansion joints as compared to the vapor barrier. It seems the best place to put the felt is between...

Hi Guys, Getting close on the foundation for the new (21x44) garage. The digging is done and the forms are going up. Pretty psyched. I am going with a 6" slab, 4000 PSI concrete, #4 rebar on 10" centers, on chairs, over Stegowrap. The concrete contractor says overkill. Perfect. I asked...

Greetings, I am building a 22x44 garage in the Bay Area, CA. I am finalizing (upgrading) the plans for the concrete work, which hopefully starts in 2 weeks. The garage is designed with a perimeter foundation with a floating slab which has a reinforced edge. I am planning on installing a 2...

Greetings, I just stumbled across this forum -- fantastic! I have a 30x18 detached garage that sits within a couple of inches of the lot line. It's an existing non-conforming structure. It's built on a slab, with the mudsill on top of the slab and stucco siding. I am widening the existing...
