I marked out the one hole location, drilled a shallow 1/16" hole into the top. I then put a 1/16" bit through the hole in my template and into the hole I had just drilled. I lined up the template, and drilled a second hole, then put another bit through that. From then on, I worked entirely from the template. With two bits through the holes pinning the template in place, the other holes in the template would be precisely located (or so the theory goes) on a 4x4" grid.
My first attempt at making a cutting guide didn't work. What I ended up with worked fine for cutting panels, but the guide-strip was too narrow, and when the saw was extended fully for rough-cutting the 4x4's the clamp heads got in the way. So I made another. Actually, I made two more, so that I could cut one into shorter pieces that would be easier to handle.
I made my version of a Roubo bench over 20 years ago. According to the latest bench rules it is too tall, too wide, has too many vises (I use both sides of my bench and that might be a no no, not sure ), and has far too many holes. Did I mention that I have a double row of dog holes with a user made dual row wagon vise? I had no idea they were called a wagon vise back then. Being a tool maker and tinkerer at heart I just made a vise that I thought at the time was an original idea for the main side. Couple of dowels in a piece of wood straddling the two rows and I have a bench stop, or a different variation gives me a 3 point clamping system. If that isn’t bad enough it also has drawers on the bottom to store seldom used tools and supplies. Maybe if it had taken me a few weeks to drill all those holes and mount a few vises I would only have one vise and 8 holes too. I dunno

Let me see if I can come up with a couple details. The table saw is a TS3660. So I have heard, this should be the center of your shop. My jointer is a 6 1/8" Jointer / Planer JP0610 which is 45 inches in length. My router table is the kreg router table that takes up a 24 x 32 inch footprint. My bench is roughly 30 x 70 inches and my bandsaw is 3' x3'. I have other tools as well such as a portable 12.5 Delta thickness planer in addition to a wall mounted dust collector. To add to the list, I am just about to get a 10 inch makita sliding compound miter saw. I can see how space will be eaten up quickly. Any ideas as to how arrange these tools in such a small shop? I will get pics a soon a I

I decided to finish the top with a number of coats of Danish oil, followed by a coat of wax. I applied the first coat of oil in the usual manner, making sure to cover the edges, and down the holes. I applied a coat oil to the top side of the shelf, as well. Wipe it on, let it sit wet for half-an-hour, then rub it off. Wait a day or two, add a second coat, and then again for a third.

He also took our Timber Frame Tiny Home course and brought home one of the structures to finish for himself (you can follow his progress on his blog!  Here’s what he had to say about what led him to PTSW, his experience so far, and thoughts for the future:

We are especially proud of Post Woodworking’s Brunswick style shed. It has all the rugged features and simple, beautiful mystique of a Maine coastline. Natural-wood siding options, in pine or cedar, offer a rustic aesthetic. Or, choose a vinyl color that complements our home. Once inside the Brunswick, its unique, two-sided sloped roof maximizes headroom, making space for you to better maneuver a rake. Black architectural hinges and hardware lend distinguished contrast and quality to this basic but appealing storage solution.
