Chuckle. Little do they know. Heck, Jon, I have 2 of those cheap electric heaters, one in the garage, and one out in the shop, with digital controls because I've found, like everyone else I suspect, that the heaters with manual dial controls will start sticking on after about a weeks running. These digital things forget their settings in any power failure of more then 3 or 4 cycles duration. I find I have to reset these at least monthly, and often more often than that. Poor maintenance of the substation regulator switches are the cause of 90% of that folderol. Even though it was 14F here last night, with one of those, and a dehumidifier trying to wring a little water out of the low humidity air in the garage, the temp in the garage is above 60F right now. The shop building isn't anything resembling insulated, but one of those digital heaters, set on low speed & its minimum of 60F, keeps it well above the dew point in there so my gear doesn't turn bright red with rust. But anybody with a modicum of sense can see that shed has heat, snow on the roof is gone in <24 hours, maybe with 3" diameter icicles hanging on the edges. I have considered building another, this time well insulated, but I don't have the real estate to do that without tearing that one down. Since this one is an overgrown garden shed (12x16 for roof footprint, a hair under 10 feet wide on the floor) it doesn't have enough flooring to tolerate heavy stuff so despite the middle of the floor originally sitting on 5 each 18" square pads, the middle now has about a 5" sag in it after 10 years of holding up a 400 lb jointer & a 250 lb bandsaw. There is no way, in this yellow clay soil, to set anything one can call "permanent". This house, with a full basement, has I believe shifted upwards, floating if you will, at least 2" in the 22 years I've been here. Either that, or the 'dirt' all around it has settled anywhere from 3" to 12" all around it. Built in 1974, when I moved in in 1989, we still had those corrugated, curved steel window wells around the basements windows on the downhill side, holding back around 8" of this so-called "dirt". I took them out 10 years ago, and the 'dirt' is now around 4 to 6" below the bottoms of the windowsills. A 3' wide sidewalk, which came from a poorly paved drive to a 5 foot square front stoop against the front of the house went way out of level to the point of dangerous so we put a 10x26 foot deck over it in about 1999. That fell short of reaching the drive by 11 feet, so when I built the garage in 2008, I extended the garage floor pour to 10 feet out, and along the front of the house about 11 or 12 feet to level that up again, so there is from 6 to 13" of new concrete there, with around 8" new on the garage floor itself. Right over the old carport stuff I probably should have jackhammered out but that would have raised the cement bill another $2200 to reach the grade level I wanted. Then I had the rest of the drive blacktopped a month later. Paying a bit of attention to drainage when we floated it, I believe we've deflected the majority of the water away as that area, unlike the garage floor, has not developed any hairline cracks, (yet, I mean after all, it _is_ cement, it _will_ crack...) Next time I build, I will set footers at least 12" wide, sitting on 24" wide pads at the bottom, & 3 feet deep, then level the grade inside, put down 4" of styrofoam for insulation on 2" of sand raked dead smooth, and then pour about 8" of concrete full of wire on top of that for a floor. That of course is in my dreams, I am 77 & that sounds like a hell of a lot of work when I would rather be enjoying what I have, in the time I may have left, so we both know that is a dream based on what I shoulda/woulda done in the first place. But I built it for under $500 in materials per purchase so I didn't need to get a construction permit. Note "per purchase" qualifier, it was 2 or three trips IIRC. :) Now, since it exists, its on the taxes but grandfathered. Keeps me out of the bars don'tcha know. Dreamers are like that. Hindsite, always at least 20-20, often even better. ;) Cheers Jon, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
