A Dedicated Sharpening Bench part 3

With the bench top work surface squared on six sides Ill measure and lay out the rabbets for the bread board ends.

Deep scribe lines will help eliminate cross grain tearing and when I clamp the piece into my shoulder vise Ill again add my thicknessed backer board to help with the spelching. I begin the rabbet with a special purpose rabbet plane but once established I change over to my medium shoulder plane. I find I get a better inside edge with the shoulder plane. I think this may have something to do with the nicker on the rabbet; its necessary when getting the rabbet established but I find the small nicker helps the plane to slowly work its way out from the edge. With the shoulder plane this is eliminated and I can create a much cleaner rabbet.

I should mention that the rabbet plane I was using has a small set screw so I could have stopped and retracted the nicker after the first few passes, but having the shoulder plane ready was a little faster.


Ive only cut my dovetails into one end of the apron- Ill wait until I finish and fit the main work surface into the side aprons before I commit to the placement of the opposite front apron.

Bread Board Ends
At this point I can dry fit my dovetails and check my dado is lining up between the pieces. I measure and divide the long tenon I still have rabbeted into the ends into three tenons. The entire length of the side will have a small shoulder plus these three tenons. I mark out the cuts and the mortise position inside the dado. For 90% of the mortises I cut I follow this procedure. Once properly laid out I begin with a brace and bit and remove the bulk of the waste.

I then follow with a mortise chisel and clean up the ends as well as determining the final depth. With the mortises chopped, the tenons cut Ill try a dry fit. Now I can establish the opposite end of the front apron and I lay out and cut the through dovetails.

The back apron is laid out and the dovetails are also cut at this point.

I follow with my plough plane and plane out another dado into the top of the rear apron. This groove will become a channel for a work holding tray later in the build.
From here I cross cut, plane and glue up some pieces to create the back splash which also serves dual duty as the front panel on the tool tray.

This also gets a matching groove opposite the rear apron we just finished. Ill bevel the inside of these grooves to make the sliding tool holder a little easier to move.

I have my work surface and apron joinery complete; in the reading and research on work benches Ive done I decide to incorporate a through bridal joint for the front legs where they meet the apron. This will create a very strong frame as well as making the front legs of the workbench flush with the front apron- a real benefit when I add some other work holding features to the piece. This being a small work space I try to make the most of my workshop projects and have them serve dual duty.
I lay out and rip down the deep leg joinery; this is sawn down and then the bulk of the waste is removed with a fret saw and cleaned up with a chisel. The corresponding tongue of the slip joint is cut into the front apron.

That completes the top joinery and front legs for now; Ill get my stock ready for the rest of the frame and start the mortise and tenons next time...
cheers!
Additional content-
Had a comment on how I cut the half lap in the legs- here are a few additional shots. The half lap or bridal joint is laid out and the legs are ripped down in my shoulder vise. I then remove most of the waste with a fret saw and clean up the bottom with a chisel. The small rear shoulder that will sit under the table top is cut on my bench hook- hope that explains it more clearly...thanks for the comments.
