When you move it away from the panel, are you using the same breaker? Breakers do wear out. I had one in my old garage that trips if anything more than a drill was used on it.
#6 is good for 60 amps. You're fine using the 100 panel in the garage, just make sure the breaker feeding it is 60 amp.
1 - You need a separate unbonded ground buss. They are bonded at your main panel, but the sub panel's must be separate. Make sure the common (white) bar is not grounded...
How many "parking places" do you plan in your 30x48 area? My 24x40 shop was built with intention of a single "space", but I'm putting the asymmetrical lift as far away from the door as I can, so that it will be out of the way if I'm just detailing, or working on larger equipment.
Here, you can't go through a wall with copper or use copper inside. Should be regulated to 10" w.c. and 1/2" black iron is fine. You should be able to use 3/8 copper outside for your connection without a problem.
They don't need to be flush to be seated. I'd be more concerned with the one on the crack. You really should be away from joints or cracks like that, and I'm pretty sure the requirements are 12"
You have to pay for the service - I think Verizon charges $30-40 a month for it, and then depending on if she has unlimited data or not - you'd have to watch your usage. You'd need either a laptop, or a WiFi card on your computer to connect then.
I don't buy 100 watt bulbs often, but they do have a use. Squiggly bulbs don't warm the chicken coop or keep the gas regulator from freezing up. Just put in my order at 1000bulbs.
I'll carry a balance for a impulse buy for a week or 2, but then I pay it off. Mine would probably like a constant payment from me, but I don't like feeling the black cloud of debt over my head.
A lot of things got in the way, and while I have made a lot of progress, most of it didn't produce any real visual accomplishment since I didn't take any pics during. Back to working overhead, and just about finished insulating the ceiling.
