Working with wood fresh from the log, this green woodworking project is the perfect introduction to edge tools and wood grain.  In the first week you will produce a three-legged stool using buck and “whip”saws for crosscutting the log to length; wedges and froes for splitting out leg stock; drawknife and spokeshaves at a shaving horse for shaping the legs; and using travishers, rounding planes and specialized rasps for shaping the seat.
Not sure about Midwest but I have a 24 x 14 Game rm attached to my shop and I put a small window unit/heat pump in the wall. It stays comfortable all year round. It get really hot here and we had a several day in the 20's this winter but it's insulated well. That might not be as cold or as hot as in some places but the unit I haze does not run that often and has a low cost rating. I'm planning on putting a larger unit in the shop area even though I do like to work with the garage door open. The door is insulated so I can run A/c in there. Just my .02.
While $115 may seem expensive, try accurately boring a grid of 20mm holes on 96mm centers in 3/4 MDF. I have for a table for our retirement community shop - - its a pita. Plus the MFT material seems denser and more water resistant than garden-variety MDF. And the single-thickness has proven sufficient the last several years on my original 1080s. Still dead flat.
Then I flipped the top and the base, lied up the base in the proper location relative to the top, I then positioned the front vise and the support MDF for the end vise, and marked the locations of the bolt holes. Then I flipped the base right side up, drilled small pilot holes from the bottom side where I had marked the locations, and then drilled shallow countersink holes from each side, then a through hole that matched the bolts. Finally I tried out the bolts and washers, and deepened the countersinks until the heads of the bolts were just below flush.
You may even want to put yourself in the picture. If your workshop space already exists, find a large piece of cardboard, wallboard, or plywood that’s about the size of the workbench top you envision. Find a couple of stools or chairs, perhaps a few books, and turn them into stanchions to support the “benchtop.” Is it too big for the space? Is it large enough for the tasks you envision will be performed upon it?
The book is well written and easy to read. The illustrations, I'm sure were excellent in 1914 and, are still adequite now. Most of the designs seemed repetitive, though. I wish more attention had been given to lashing materials. If you are looking for that you will find almost none here. The book was fun to read and provided enough inspiration to make my brother and me attempt a large hut.
