« Part 5: stretcher tenons and dry fit Part 6 of Roubo-ish Workbench series no next part

my first adventure into the wonderful world of DRAWBORING was a great experience. it was not difficult and the results are amazing.

drawboring is pegging a tenon into a mortise with the peg-hole in the tenon shifted slightly toward the shoulder causing the peg to tighten up the joint

I used red oak 1/2” dowels from lowes. I took my time going through all their stock to choose the straightest grain dowels. the ideal would be to make my own from riven white oak, but the red oak worked nicely

here’s how my day started, my bench in pieces ready for assembly

boring 1/2” hole through bench leg

drill bit was just barely long enough!

drilling tenon about 1/8” toward shoulder relative to the hole through the leg

looking through dry fit… that peg is going to have a meandering path!

... so I chamfered the hole through the tenon with a round file

and sharpened the pegs

peg driven home… see it poking out the bottom

one set of legs done… it is SOLID!

one of the four tenons split, but I also used a lot of glue and it’s still rock solid

finish line in sight!

some 3/4” pegs for the aprons

a blown out 1/2” dowel on a lower skirt

It was a great day in the shop! thanks for looking!

I was just watching the wood whisperer last week; a video showing drawboring and the strength it adds to a joint. Everytime I see a quality bench on LJ I get a little envious :) – it’s a beautiful piece of work you’ve put together and a great way to secure things. Sounds like you enjoyed the work as well…. which makes it not work at all I suppose.

Now it’s on its own legs! Looks great, congrats!

I see you used Titebond for gluing. Was its open time enough for assembling and drawboring? I’m now doing mortise & tenon on the legs of my own workbench, and I started to lean towards epoxy for gluing just because of longer open time.

Yuri it was pretty dry in the shop so I was worried, but I ended up having no issues with the glue.

Great progress John! I would agree draw boring is definitely not boring.

I love the pictures of all the parts together before assembly. I think I forgot to take one like that.

This is going to be a great bench. Cant wait to see it finished.

Yuri, for what its worth I used no glue at all and my bench is rock solid.

John, I see, thank you.

Mauricio, I’ve got couple of cracks right in the mortise area of the leg, so my paranoid self really wants to put some glue in there. Maybe glue just this m&t pair, not all of them…

You give me too much credit John, I didnt know the file chamfer technique.

I hear you Yuri, Have you thought of using hide glue for the open time? Easier clean up than epoxy.
