Last Minute Door Update

Cutting Tenons

I was just dumping my digital camera getting ready for summer vacation and realised I had some pics of the tenons being sawn for the door project. Im using my 14" Rip saw and my 12" carcass both by Lie Nielsen. Here is some of the progress.

To begin a nice deep scribe line with my favourite marking gauge establishes the tenons width; in this case theyre all 5/8" thick, 3" deep and the rails being cut here are just under 7" wide. The Quarter Sawn White Oak is hard and unforgiving so make sure you have sharp tools when working this kind of wood. Ill go back and forth over the pieces to get these lines as deep as the small cutter on the gauge will allow. The base lines are all established with my engineers square off of one reference edge and then one reference surface.

I begin each cut with a small kerf at the far side of the piece and then slowly establish the straight line across the piece using the back heel of my saw plate. I can bear down and get a nice deep kerf established with this method of using the heel of the saw where the teeth remain the sharpest. Once the kerf is adequate I begin the sawing; I saw down until my back saw just about bottoms out and then Ill rotate the work piece in my tail vise and continue on from this opposite side.

Youll notice in the video below Ill use my Ryoba to finish off the cut to the required depth. From here I get out my miter hook and another bench hook to support the Oak and cross cut to the shoulder line. Again Ill slowly begin the kerf using the heel of my saw plate and work my choice down into the cut. Finish sawing with the work piece back in the tail vise and the Japanese pull saw to complete.

Ill do all of the rails and moulions for the entire door before I mark the pieces to saw the haunches in the tenons. In the shot above you can see the first haunches are cut in the small moulion. Its one slow step at a time in the Unplugged Woodshop. Enjoy the process and try to split these lay out lines. The video below will show the procedure...as alchoices, I was spinning some vinyl...Neil Youngs, After the Gold Rush one of his best and still one of my favourites. To get a good idea of the time line to complete this one cut you may notice by the end of the job the record needed to be turned over! Ahh the joys of vinyl. Cheers!
