About a month ago, a fellow stopped in to ask if I would repair some chairs. My usual response is - can I build you new ones, instead? These chairs weren't in horrible shape, and they were made of teak, so they were definitely worth saving. But one was wickedly broken. This back seat rail is split beyond repair. Luckily, only one chair was this bad.
Someone had tried to fix these chairs once before; there were at least two different types of glues in most of the joints. The first step was to remove the corner blocks. Whoever put those on wanted to make sure that they never came off! They were stapled, glued and screwed. With slotted screws, which are a PITA to remove. They were rusty and stripped, and made this part of the job pretty miserable.
The only way to remove the corner blocks was to cut them down the middle and break them apart.
But pulling out the staples was a little tougher. I use special pliers, made for removing screws. And channel locks for pulling out the staples.
Once everything is apart, more cleaning is needed. This tenon went from this
The mortises were in very bad shape, which required quite a bit of work with a small chisel. Can you see why I don't like doing repairs?
It doesn't make sense to be lazy when repairing a chair; take your time, remove all the old glue and clean up everything. Reassemble the piece using smart joinery techniques to ensure that your repairs will last a long time. Otherwise, what you've repaired might end up in my shop someday!
