@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.

Thread the rods through one of the legs, then set the leg flat on the table. Insert dowels into the dowel holes. Place the matching stretchers into place. Put dowels into the dowel holes at the top end of the stretchers. Place the other leg onto the threaded rod and settle it down onto the dowels. You'll probably have another opportunity to whack away with your rubber mallet.

I agree that even at 12x12, things'll be "cozy" inside. That's OK. Keep in mind that this will be a general purpose hobby shed, not just a wood working shed. Even 12x8 would be plenty big enough for building 1 meter wingspan bungee launched RC gliders. And for the electronics projects I do, I only need enough workbench space to do some soldering with a 3rd hand (for electric guitar pedals). If I need more room than the shed offers for wood working projects, I'll just roll the table saw down a ramp and do my cutting outside in the sun.
Much like the dimensions of a bench’s tabletop, the weight capacity will similarly affect what size of projects you can work on with your bench. A common weight capacity sits between 220 to 250 pounds. While this is okay, it will limit some heavier projects. Ideally, you should shoot for 300 pounds, though some benches can offer 500 pounds of weight capacity or more.

This trade and technical college currently serves over 15,500 credit students from its campus in downtown Los Angeles. Through the Construction, Design and Manufacturing Department, full-time students can enroll in a daytime certificate or an Associate of Science program in cabinet and millwork. Evening programs for current craftspeople include a certificate program in construction technologies and an Associate of Arts in cabinetmaking and millwork that provide students with the skills they need to work in construction or manufacturing.
I would say take the shed, you'll find some use for it. I have contemplated this question also. I have a 20' x 11' basement shop, thats quickly loosing space. If you live in an area with a harsh winters (say the Midwest), does it make sense to heat the shop through the week if you are only working in the shop on the weekends? Or do you run the heaters just when you are working in the shop? What kind of heaters are recommended (radient, wood stove, etc.)?
Another aspect that might irk some buyers is the fact that the capacity of this bench is less than great outside of weight. The top’s surface area is a bit on the smaller end, though its length is more in line with larger models. The width though is less than two feet which can limit some projects. Similarly, the vice capacity is the second smallest on our list at 4 ½”, though this too can be modded with optional additions.
I'm not kidding when I say that this shop has everything you need to make a project happen.  They are not only equipped but also some of the nicest people.  Supportive and, mostly, willing to help you with your project.  The idea is for you to do it on your own, but if you get stuck I have yet to see someone say, "no, figure it out on your own."  they are helpful and fair.  I love this place, and the people I have met there.
Though still straightforward in design, this bench distinguishes itself from many of its competitors with the sheer wealth of storage options. It includes two drawers of equal size with an additional drawer of double size as well as a spacious cupboard. Altogether, this provides for more storage space and organization than any other workbench we reviewed. Of course, this bench also comes with many of the same advantages and disadvantages that you would expect to see on other models within this lineup.
Before joining the top to the base, loosen the bolts and screws on the lower stretchers to create a little play in the leg posts. Align the top notches with the leg posts and tap the top into place with a hammer and piece of scrap wood, working evenly around the table until all leg posts are level with the tabletop. Tighten the lower stretchers and you’re done. A hefty thanks to Doug Merrill for this weighty idea.
One quality about this bench that is definitely lacking is space – both tabletop and storage. The Olympia Tools does provide an adequate shelf, but it does not come with any drawers, nor does it offer the option of adding them later. The table top is the smallest we saw at 50” long and 2’ wide, though the width is actually better than most of the other table we reviewed. Still, a significant chunk of that width is occupied by a trough. This trough is designed to hold smaller workpieces to keep them from falling or getting knocked over, but it removes about 6” of width from the tabletop.
Our Lexington model was designed to match many traditional New England homes, in Massachusetts and beyond. The steep pitch of the roof is built to withstand sometimes-punishing New England snow loads and complement today’s home design styles. Post Woodworking can match most vinyl siding colors, so that your shed color will coordinate with your home as well. And as is the case with all of our sheds, interior solar lighting is available to light up the night.
