Tracy Carved Knuckle Hand-Rest (Cont'd)

 

Turn the arm over and start defining the web between the knuckles on the top of the hand-rest The gouge will only chop down so far into the end grain of the handle. To clean up and shape the webbing in the end grain, I find it most convenient to clamp the arm bow and rest vertically in my bench vise. See next image.

The roughed out hand-rest mounted on the arm-post.
 
While the rest was still clamped upside down on the bench, I used a japanese style trim saw to under cut the block up to the lines marking out the volute. The I pared away the waste, smoothing the back of the block at the same time using my bench chisel.

Clamp the arm bow to the bench. The chop and pare away the waste to start forming the round knuckles.
 
To do this, I set the arm on a spacer made from scrap to help clamp the bow firmly to the bench. I am using a 3/4 inch wide chisel and mallet to chop out the waste quickly. Then paring the block down to meet the mark out lines drawn earlier.

Sketch in the shape of the volute on both sides of the hand-rest.
 
The volute is drawn with a black marker for the sake of clarity. Pencil lines are fine. I  marked the centers of the ends of the block with a cross, then carried the lines around all sides of the block. This will help keep the barrel of the knuckle body symetrical as you round it.

Trim the over-sized lower block to match the profile sketched on the hand-rest using the bandsaw.

Tracy Carved Knuckle Hand-Rests

 

Glue on the third block to form the carving blank for the knuckles.
 
To the underside of the hand-rest blank glue on a third block of wood. This piece is 1-1/8 inches thick and 1-3/4 inches long. I leave it's width over-size and trim the waste off after the block dries. I take time to plane and sand the underside of the two piece top assembly to get a good glue joint when the bottom block is glued on.

After fitting the arm to the arm-post, go ahead and cut out the shape of the hand-rest marked out earlier.

Tracy Carved Knuckle Hand-rest (Cont'd)

 

Back in March I started posting a series of pictures showing the creation of a pair of Tracy pattern carved knuckle hand-rests. I set that series aside while I completed two chairs, and instead posted a number of photos taken when I built a second Shaker work-bench. With those chairs delivered, I am now working to complete one of my large Sack-backs. This chair has hand-rests based on those of Ebeneezer Tracy. As I work on the hand-rests I will continue to post photos of my progress.

The arm bow drilled and fitted to the chair's arm-post.
 
This picture compresses several steps required to fit the arm bow to the partially assembled chair.
1. A 5/8 inch diameter round thru mortise must be drilled in each hand-rest blank. This chair requires a mortise drilled at 15 degrees to the side and 17 degress to the rear to fit the angles of the arm-post in the seat.
2. I use a tapered reamer to widen the mortise on the blank's underside to help the arm rest fit the curve of the arm-post baluster as it settles in at the height above the seat that I want.
3. As I trial fit both rests, I pare down the tenon and the upper end of arm-post balusters as needed, using a small carving knife. Lots of on and off trial fitting to get everything right.
 
The hand-rest pattern was drawn on the glued up arm bow earlier. I leave the glued up blank uncut until after I drill the thru mortise. The extra width and length gives me more meat to clamp on too when drilling the mortises.
