I was asked to repair and spruce up an old chair.
The back was broken when I got it, and after I glued it together, I cut the chair open to strengthen it.
With this simple jig clamped on, I was able to cut the chair open and add some reinforcement.
Once exposed, you can see that the chair has been repaired many times!
The recess is filled with a piece of 1/8" steel, the rough surface and cut marks are "tooth" for the epoxy to grab.
I cut off as much as I could, so the steel was in the centre of the back.
When the steel was placed, it was covered by mahogany, and once set, that was shaped to match the chair contours. Then came the spraying!
I was asked not to remove all the patina when refinishing, and you can still see the marks in the chair.
