With the seat tenons wedged, it’s time to pin the tenons. I wedged the tenons first so that the cross dowel wouldn’t potentially prevent full travel of the wedge. I chose to pin 8 of the 14 seat tenons.
Pin the Seat Tenons
Drill the pins in 1 1/4”. This secures the tenon without going too far into the seat.
My dowels were closer to 13/64” than 3/16”, so I had to use a metal bit to drill the holes. Chips don’t eject as well from metal bit. Compounding this problem, the glue was still wet and formed a strong mix with the drill dust. This plugged up the bit pretty bad and caused a couple of the holes to smoke. I could have caught my chair on fire!
Tap the pins in place and chair assembly is done for the day. Liquid hide glue takes a full 24 hours to cure. There are no clamps since everything is held in place by pins and wedges. I’ll have to wait until after church tomorrow to sit on it.
Plug the Brace Holes
With the chair already positioned, I finally plugged the brace holes. I can’t resist the urge to tap these in place, so I clamp the unsupported sides to prevent a blow-out.
Next, turn six spindles for the arms…
