That's a Micro-Mortise

You know that you’ve been building a Roubo workbench when you chop a 1-1/4″ wide, 4″-long and 3″-deep blind mortise and it’s comically easy.

Today I’m getting back into the swing of things on this Roubo workbench. My goal is to have the stretchers dry-fit into the legs by the end of the week. There are several things that could get in my way.

1. I have to do my taxes tomorrow. Yikes.

2. My day job. I’m exactly 37 e-mails (dang, now 38) behind, and I still need to write a feature story for the August 2010 issue.

3. It’s so nice outside that I might just strip buck naked and air out all my crevasses. It has been a long and malodorous winter.

Stay tuned to this blog or, in the case of No. 3, your local police band radio.

    Re photo above: Chris, are you really beating on your Japanese mortising chisel with that wooden mallet? Japanese woodworkers use steel hammers, thus there is no energy-loss by compressing the wood of the mallet head. I particularly like the ones with the short and fat head, which concentrates the weight near the centerline of the handle – "the best balance for chiseling," according to the Hida Tool website. Most Japanese hammers have one end of the head slightly curved, but according to Toshio Odate ("Japanese Woodworking Tools"), the flat end is the one that should strike a chisel. With the ring at the top of the chisel handle properly seated a bit below the end, as yours is, the hammer head will only strike the wood of the chisel handle.

    It was really cool hanging with you at Jeff Millers last week.
    I loved the "Shooting Board from a Bench Dog trick"
    And adjusting the height of the dovetail board in the vice via laying the other member on top of the plane and squaring them up with the back side of a chisel.

    Plus, my new books and attire were a nice acquisition.

    Thanks Chris.

    Why was I thinking this bench would go stretcherless? It would seem that those massive tenons would get the job done, unless you are thinking that the extra weight of more frame members would be needed.

    Chisel looks Japanese to me. Ray Iles no longer cutting it for you? Or is this someting we’ll see a review of in the future?

    I suppose you have to balance the physical airing with the mental airing of crevasses you’re doing here on the blog. On the other hand, given the choice, which would you prefer: No. 1 or No.3?

    Ah, Spring!

    The sap is rising and a young man’s fancy turns to streaking. Or something like that.

    I remember when I chopped a mortise like that in my hard maple top, the chips where flying like bullets at Normandy.

    ‘Course, my mortise wasn’t quite that purty. But I’ll forgive you for that since it’s spring!

    Chris:

    Thanks for the warning, but, seriously, a little too much information!
