No clamps required for this assembly

What else can I add? Thank-you Sandy — your help was invaluable!

This was an assembly of a large desk base with four aprons, three stretchers, and four legs; it was assembled with mortise and tenon joinery, prepared as I showed in an earlier blog entry. You can follow the work on the stand-up desk at this link.

After applying glue to the mortises and the tenons, I applied a little glue to the tapered tips of the pegs and drove them home; the liquid hide glue is a wonderful lubricant, too! No clamps were required to assemble the aprons to the legs (and the stretchers to the legs, etc.):

I used liquid hide glue, as it has a long open time; I felt this was the best way to assure myself of a panic-free, clamp-free, and relaxed time during the glue-up of a very large desk base. After the glue dried, I trimmed the pegs with a flush-cutting saw, and leveled all the pegs using a little block plane. Now the drawer fitting begins in earnest, including stops and alignment strips to ensure straight travel during opening and closing. In the meantime I will be touching up the shellac layers, to blend the areas I planed to the surrounding areas. Finally I will apply a durable varnish, Target Coatings’ Emtech 2000wvx.

I had to use a few clamps to hold the dust cover in place, while the glue dried – here is the dust cover in place:

If you want to eliminate much of the anxiety during large glue-ups, I recommend the use of the drawboring technique to pull together all mortise and tenon joints tight. Even the double-tenon/double-mortise joints I used on the stretchers between the legs went together flawlessly; properly tapered, the pegs snaked their way nicely. This was the double mortise and tenon joint at the end of a stretcher, and made with an FMT Pro:

I admit this was the joint I was most concerned about prior to the glue-up, due to the spacing (“Will the peg find its way through the second tenon…???”). But I am a happy camper now; well, maybe a happier woodworker, as the drawboring technique worked beautifully.
