« Part 10: The Legs - part I Part 11 of Split Roubo Workbench series Part 12: The Rails »

In the last blog the tenons were complete and I trimmed the extra “margin of safety” length. It takes two passes with the miter saw. So I shaved off the inevitable irregularities.

Next is routing the mortises. Marc (TWW) demonstrates doing this free hand and makes it look easy I might add. Routing is always a tense affair for me but I give it a go. Nice results huh?

I want to make sure the dimensions and placement are correct so I went through the trouble of fixing this mistake. Truth is I really wanted to use a dowel plate.

In the end, when I went back for the second pass the next day and the little repair piece ripped out. Oh well. Things went much better after I set up some stops. Have I mentioned that cherry burns easily?

The legs sat like this for a week. Then another week. Then another week. Finally, I drilled a large 1 1/4” inch hole in the right front leg for access to a dog hole. Wierd but that is the plan. In the same leg I bored three holes for the holdfast. First, I counter-bored on the back at 1” for a depth of 1 1/2”. This will create an effective holdfast hole 3” deep.

Then the front 3/4” holes were drilled.

Interestingly, when I tested my holdfasts for the very first time, both of the blacksmithed ones held like champs. however, the grammercy one did not hold at all. Maybe I need to de-wax them and scuff ‘em up with sandpaper.

The 3/8” holes for the draw bore pins are drilled as well. The legs are done with the exception of the left front leg, that one will get lots of love during the leg vice build.

Thanks for checking out the progress.

This bench s going to be beautiful Scott. If you saw some of my mortises, you’d laugh your head off. The joints have never come loose though.

Thanks for the kind words.

I still have the legs at a length that will result in a finished height of 35”. Yet, the legs are already laid out at 1/2” increments if I decide to cut the legs lower the bench to 34 1/2” or 34”.

I was really suprised that the Grammercy holdfasts didn’t work.

This build is a wonderful learning experience. I am performing operations and using tools that I have never used before. Take for instance the Yankee brace. I have played around with and it doesn’t need TLC. But actually take that tool and bore real holes in a real project is awesome. I love that thing.

Good progress Scott and you bring up something I wrestled with last night. What is the best way to chop out a mortise this big?

I did two last night for my bench 5.5”Lx1.25”Wx2”D. It aint easy. I first tried boring it with my brace, in oak thats a lot of work, tried forstner bit in handheld drill but that burned the wood and wasn’t much easier. I finally hoisted it up on my drill press. It worked but I almost broke my little cheap drill press.

I didnt think about routing since I wasn’t sure if it would reach deep enough. I have a template router bit, I may double stick tape some stops and try that.

“Finally, I drilled a large 1 1/4” inch hole in the right front leg for access to a dog hole.”

I’m not clear on what that hole is for? Thats a big dog hole, I’m just trying to figure out if I need one of those. Thanks!

Mauricio, that hole is specific to this plan.

It is hard to see in the BenchCrafted pic but a dog hole sits right over the right front leg. On the left side, you skip a dog hole where the left leg is. I assume that the dog holes closer to the wagon vise are more valuable. Makes sense. So, in order to accomodate the dog hole you have to drill a verticle hole into the leg tenon and then the horizontal 1 1/4” hole for finger access.

Does that make sense?

Got you! Makes sense.

I figure if I have a dog whole right before the leg, then skip over it and continue at one whole every 3” to 4” inches I can cover pretty much any length of clamping on the wagon vise. The whole in the tenon would make it nice and consistent though.

Also, how far down from the top will the hole for your leg vise screw be?

... to be able to push the dogs out if/when they get knocked flush to the benchtop. And when the holes get filled with muck. Got it (I was missing that part, too)
