In the Bally’s Total Woodworking Club meat market I can strut proudly when I show off my Roubo workbench and testify to it’s pumpitude by showing off the empty bottle of Ibuprofen for my sore muscles! In an earlier post where I talked about wood movement, I had started laminating the bench top into 6 inch wide sub-assemblies.

I got two of these done before I read a post by Mark (Loogie) on Lumberjocks about the building of Bob’s Bench.
Mark mentioned a technique he was using to keep the individual boards in line with one another to decrease the amount of flattening that would need to be done later. By glueing up the top one piece at a time, he could run a clamp perpendicular to the clamping pressure across the joint thereby clamping the boards into alignment. Any more than 1 board at a time and the thickness would be too great for your average clamp.

While in hindsight this seems pretty obvious, it was a revelation at the time so thank you Mark. I immediately stopped making my sub-assemblies and starting adding one piece at a time. This kept my boards in almost perfect alignment as I started to build the top.
Here’s 3 boards in the clamps

Roll on some more glue and now 4 boards in the clamps

At this point my bench is in 3 pieces. Two 6 inch wide, 3 board assemblies, and one 7 inch wide, 4 board assembly. I had already jointed the 6 inch assemblies and using the new clamping technique had allowed me to form the 4 board assembly almost flat already so I skipped the jointer (mine is only 6″ anyway) and went straight to the planer to flatten completely. This is where the workout really got hairy. I wanted to make sure all 3 of these assemblies were exactly the same width so I could continue to use Mark’s clamping strategy to control the final glue ups since from here on out, only handplanes can tame this massive beast due not only to limitations in machine width capacity, but sheer weight.
With each one of these assemblies weighing in over 50 lbs, I took very light cuts with the planer and made sure I have perfect infeed and outfeed support. This adds a new element of safety to woodworking because dropping one of these would definately break a foot. After breaking a serious sweat making 3-4 passes through the planer with these beauties (don’t worry I got it on film so y’all can laugh at me later) I was at a uniform thickness and flatness all around.
Time to get serious about glue up. I could continue to use Mark’s technique by clamping across the joint on the very ends, but in the middle I would need to make some cauls.

These are just some scrap wood (I’ve got plenty of Ash laying about) covered in packing tape to prevent glue from sticking. I even planed a slight crown to the boards to provide extra pressure in the center of the caul across the joint. Now I could roll on even more glue, and, oooommmfff! Lift a 50 lb assembly on top of another one to make a 7 board glue up.

More glue, heavy lifting, and a hernia later and I had 10 boards glued and clamped.

This is the main bench assembly after I scraped off the glue using my number 80 cabinet scraper. The bench top now measures 4 inches thick, just over 8 feet long, and 19 inches wide.

It’s enough to bring a woodworker to tears. Just gazing out over the sea of laminated Ash! OK no more waxing poetic! Next I’ll flush up the ends using the same technique I used to cut the bottoms of the legs by cutting with a circular saw from both side and evening the face out with a flush trim bit in the router. I will keep the bench at this width to lay out the cavity for the end vise, then I can add the dog block and final laminations to bring the bench to around 26 inches.
I need to go rest my muscles now!

Beautiful, man.
P.S. Your number 80 cabinet scraper measures 4 inches thick, just over 8 feet long, and 19 inches wide? Dang that’s a big scraper. ;^)

Keep plugging Shannon! I feel your pain. My top sub-assemblies were over 7″ wide, and they weighed almost 80 pounds. Jointing those was a bear, even on a long bed, 10″ jointer. And I’m about to repeat the task. Yep, I have another Roubo in the works…

I’m with you on the workout. I’ve finished my base and got my top glued up. I in the process of chopping out the mortises into which the legs will set. I’ve had a wonderfully family-free stretch of a few days and so I’m working like mad to take full advantage. That means I’m working in my shop about 8 hours a day. That’s the good news, and the bad news because I am sore, beat up, blistered and very happy.
My Roubo bench top is short because I have a small shop in a spare bedroom. It’s 60″ long and 24.5″ wide by 4″ thick hard maple. I weighed one of the pieces (I laminated up 14 of them) and just one weighs exactly 10 pounds. That’s been fun to manhandle!
Good luck with the rest of your journey. My path is a little different from yours in that I have no power tools so I bought my stock s4s dimensioned from the lumber yard, but much of the rest of it goes along similar paths. If you’re interested to see where I’ve been and where I’m going, head over to my blog, linked to my name.
I look forward to seeing more reports of your progress. I wonder if Chris is aware of the phenomenon he created with his slim little workbench book?

I have a question about the mortises for the legs. While I suppose you could chop them, as Andrew mentioned above, couldn’t you also save a butt-load of time and just leave gaps in your glueup? So you’d have a short board, a gap (the length of your tenon), a long board in the middle, another tenon gap, and then a short board on the end. So you’re created a mortise without any of the actual mortising (which complements the tenon without tenoning I guess!).
And I suppose you could do the same thing on the outside boards, but it would probably be easier to just not put glue in those areas and then saw them out.
What did you do? (Sorry, maybe you’ll answer this later so ignore it if you did – I’ll get there!)
