Brief Description: F-705 BH - Seat Back - Drill 705F.
Now that you have holes in the 705J angle you can use it to match drill it to the 705F channel.
The plans call out a 1/8" gap between the top flange of the angle and the top face of the 705F channel. I used a couple pieces of scrap 1/8" AA (aluminim bar) as a temporary spacer. Put the 1/8" spacer between the parts and cleco clamp the 705J angle to the 705F channel and drill.
