Any update? Very interested in this.

Do you think a walk behind burnisher would have enough power to cut using the 220 pads?

MY .02c... It depends on your soil, your building and foundation system. I full perimeter footing with rebar re-enforcement is hard to beat and it's what I did but it may be overkill if your structure and use don't require it.

I would stop payment but that's me. I would stop payment and then let him know that due to the gravity of your concerns and his failure to contact you as promised, that you will withhold the final payment until an agreeable resolution is reached. One thing is certain- this will surely motivate...

I could be wrong but if your jurisdiction has adopted IRC and it's getting inspected, you may need a continuous header not so much for vertical loads but for wind loads. You might want to look up "narrow portal framing" if both doors are on 1 wall and the wall doesn't allow for sufficient...

Tommy- how would you recommend removing the compressor oil and purging? Do mini splits typically have built in driers?

Do you see a problem running individual 14AWG THHN inside 1/2" PVC liquid tight between the two units? 'm wondering if that would pose a problem for the communication line?

Sorry Justin- from your first post- you listed the 2.5T unit as being a 2011... and also said that "while he was out" (working on the 3T) - you both heard the 2.5T compressor kick on while the fan was going- thinking the compressor had been in thermal shutdown. You also stated he "checked"...

thanks- so how long had the 2.5T been running with cap wired wrong? To start the compressor on just 5 micro farads when it should have been 40 seems problematic as that tolerance is usually 6% so the low side of the 40 should have been at least 37uF. I'd double check your wire swapping just...

Sorry Justin- it's a bit confusing to follow.... I'm not sure if your talking about the 2.5 or the 3t unit in the paragraph that starts "while he was out"? Just before that you mention the 3t is "good for now" so I presumed you meant the 2.5t BUT then you say "I opened it BACK up" and found...

Good to know... now if I can just find the time to play with it. BTW- I've read conflicting info on the outdoor to indoor power/communication cable. I was planning on running 14/3/G inside flexible liquid tight ?? others say you can use straight honeywell TC minisplit cable but I don't see how...

Eddie- by bench testing... I mean to hook up the entire system leaving the compressor on the floor in my shop and putting the inside unit on a bench and "running" the system as if it were installed. That will allow me to probe all the test points to determine which components must be changed...

Yes- I understand that but this is taken from: http://alltemp.ca/wp-content/uploads/2013/10/JB-Principles-of-Vacuum-Presention.pdf ...and it concerns deep vacuum changing the properties of oil within the system already. " Refrigeration oil has a vapor pressure and, by going below 200...

Thanks guys. A few things: This unit is AC only (no heat pump). One of the reasons I bought this was that I have full manuals for it including owners, installation, and service. The documentation is surprisingly thorough allowing component level diagnostics. The inside unit is no longer...

I purchased a newer 24K BTUH Sanyo mini split (20 SEER) that was known to have an issue with the inside unit - compressor was declared sound. Being an engineer with universal refrigeration license, I really want some hands-on with this technology as lots of HVAC guys around here shy away from...

I've had great luck with POR-15 on rust pitted surfaces after cleaning per directions. I have had terrible luck with POR-15 on smooth clean metal in that it doesn't stick well and I have much better luck with epoxy primer. On your tub, my approach would be POR-15 in areas you can't completely...

Not an expert but I was told you need at least 1-1/4" thick structural subfloor to avoid flexure under tile. I always took this to mean 3/4" t&g plywood/osb plus an additional 1/2 plywood appropriately fastened to that. You can go over plywood with a good latex modified thin set (I wouldn't...

http://www.superabrasive.us/index.php/products/concrete/diamond-tools/maintenance.html the mesh screens are toward the bottom of the page after the proshine discs.

yes- 1500 rpm. I have my reservations but I'm told it should work as long as it's done wet and I use surficant. The mesh wheel is about $150 and I already have the buffer so that will be my first test. My buffer has a load meter as well as a pressure adjuster but everything will hinge on if...

Thanks all- I sent Concria an email through their contact and I've yet to hear back. I have looked into other products and most were "maintenance" products for floors that had already been polished. I did make one encouraging contact. I called a company called superabrasivew and spoke...
