Most of the line weight shifts & bridges have been completed in the seating boards. The mid section base blocks are also almost complete. Still some trim adjustments to do on the rear of the blocks & also after re-assembling the seating board sections with the backrest have found another couple of lines that require some subtle alteration.
As you can see from the images the seating hollowing has been worked to a smooth blended form. You can also see the seatboard sections before they were re assembled.
Tools used include;
The arbotec - see previous entry. A good tool for removing stock rapidly, that's also it's disadvantage!
Convex spokeshave - a joyous handtool experience for cutting the hollow just the way it should be.
Rotary & orbital sanders.
Bench plane & belt sanders used for blending flat areas. Low angle spokeshave used to cut radius on rear edges of seat boards.
