I’ve seen antique cabinetmakers’ benches that are sixteen and seventeen feet long, more than three feet wide, and supported by a dozen drawers and doors—and that weigh as much as a felled oak tree. In contrast, jewelers’ cabinets seem to be on a dollhouse scale, with tiny tools to match. For most of us, however, space limitations preclude the biggest, and the smallest are just not big enough.
Yea I had a friend who went the HD route and in after putting new braces up for the roof and an extra layer of plywood on the floor he gave up the fight and tore it down. We ended up building twice the shed that was 100 times more sturdy for less than he had invested in the first one. I would go any route that is the opposite way of HD or Lowes. Learn from this guy.
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
Grizzly is a company currently undergoing an upheaval. This brand was once known as a manufacturer of professional grade tools and equipment for woodworking products. Though, in recent years, that reputation has begun to slip a bit since being bought by the Chinese company SIEG. These days, whether the Grizzly product stands up to its previous standards of excellence often has more to do with what you are buying than the company itself.
The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.

I built my first platform bed by following the steps mentioned in the tutorial and the end result was everything I expected. It was as beautiful as comfortable and strong. It only cost me around $60 to build this one from the scratch. And if I can build it, anyone can. What you need is a little bit of woodworking experience and a lot of confidence. Collect the items as suggested in the video and start working now.

Having done all this, I'm not sure I'd do it this way again. It might well be faster to layout the positions with compass and straightedge directly onto the top. Either way, you'll want to use a scribe rather than a pencil. Scribe lines are hard to see, and impossible to photograph, but the scribe and compass points click into them, allowing a precision that pencils simply cannot match.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
My wife has given me the OK to buy a "Rancher"-style shed from Lowes and have it installed in the backyard. The discounted installed price will be about $2,600 and this includes the 12' x 8' structure along with a lot of upgrades (twin metal doors, a window, 2 skylights, storage, vents, etc.). I can save about $300 if I build it myself, but my skill level isn't there yet, so I'm going to pay Lowes to assemble it. (See Post #12 below for some photos of the shed and the space I have to work with.)
