Building Bench #18 – II

While the glue for the laminated slab was setting I turned my attention to the legs and their integral tenons.  As in previous efforts the three laminae of the leg are glued up with the center lamina off-set from the outer two by a distance equal to the thickness of the slab plus a smidge, using decking screws and fender washers as the clamping mechanism.  These are removed after they have done their duty.

If I did my layout and glue-up of the top slab correctly, and cut the dovetail pins accurately on the tops of the legs,  the double tenons are a perfect fit for the mortises already created in the top slab so all that is needed to put them together is a gentle tap to drive them home.  Since the bottoms of the legs need to be trimmed to matching lengths ex poste the protruding excess is no bother to me.

Before I do that, however, I de-clamp the slab after letting it sit overnight and spend an hour or so getting the underside flat enough to seat the legs evenly.  I do not care about the underside being smooth, merely flat.  A sharp scrub plane and fore plane make short work of it, as I said it was a little over an hour to get it to an acceptable point.

For this bench I did something I had not done before and remain unsure as to whether I would do it again.  Since I was installing a vintage screw and nut from my stash I decided to inset the nut into the back side of the front left leg, where the leg vise would be installed since I am right handed (if you are left handed it goes at the other end).  Doing this was no particular bother but I am unconvinced of its efficacy or necessity.  I also cut the through-mortise on the lower leg for the pin bar of the movable chop/jaw.

Before long I was assembling the bench and as you can see the space was ridiculously tight with not only this bench but two ripple molding machines being tuned up for the conference.  Since this is the only heated working space I have, everything that needed to be worked on for WW18thC was there.  It got to be pretty chaotic for a while.  I am not particularly tidy as a workman and that shortcoming becomes really evident at times like this.

At this point the bench was assembled and I was at the 12-hour mark for the project.
