Well, the sub-floor for the workshop is gradually going down. You hear a lot about people “starting from square one.” If you ever wondered what square one actually looks like, here it is:
As of the end of last week, we were making steady progress, and were well past square one:
Thanks to looking for things to do while avoiding preparing our income taxes, I’ve finally gotten around to something I’ve been meaning to do for long time: add image galleries to the blog. You’ll find the first one in the right-hand sidebar. As you might expect, I started with sailing canoes. Not completely happy with the formatting, and I will add captions, but I thought I would put it out there as a teaser while I work out the details. Stay tuned for more.

Not to be critical of anything you are doing with your work shop but ; have you considered some sort of rigid insulation beneath your subfloor?
My cellar ‘project’ shows a floor temperature ( concrete ,measured ) of 50 -54 degree F. In order to reduce both moisture/humidity and temperature loss I will first add a polypropolene plastic sheat directly on top of the cement to act as the vapor barrier. On top of that will be half inch RIGID board insulation. ( closed cell foam.)
In an outdoor shed I have used Mylar faced open cell one inch insulation with 3/4 inch exterior plywood on top for a subfloor but found the open cell insulation too soft and compresses with normal foot traffic making an uneven floor surface at the 4X8 foot floor joints. These mylar faced sheets are good for wall insulation ( R-3 @ 1 inch ) especially for reflecting natural or artificial light within the cellar. They also can be used for celling panels either between the floor joist overhead or across them and boxing in the joist entirely. Both Home Depot and Lowes have these panels but be aware of fire code regulations and exposure to open heat sources liike stoves and portable heaters. Good luck with your project ! Larry
Thanks for your thoughts, Larry. We’ve just gone through a wicked winter here, and I found the basement to be a very reasonable temperature throughout. Our new place is a townhouse, so only two of the four walls are exterior. The flooring I’m using is Dricore, which is composed of 2′ x 2′ t&g OSB panels with plastic “feet” below each piece that keep it off the concrete to make an insulating air layer. Certainly easier to put down on your own than the dimpled plastic underlay and 4′ x 8′ sheets of OSB tapcon’d to the floor that I used last time.
