Kevin found a broken old chair and decided to repair it. Someone has attempted
to repair it with long screws, but the problem started much earlier, when the
glue failed. The joints are basically good Ė theyíre mortice-and-tenon joints
pinned with dowel.
The first step is to dismantle the chair and clean up the joints. Kevin then
applied glue to the front leg assembly and clamped it to dry while he works on
the rest of the chair. Itís important to use plenty of glue, working it well
into the end-grain and deep into the mortices. Clean glue off with a damp cloth,
and re-insert the dowel pins. Check to make sure the legs are in line with each
other and square to the rail.
Once set, the whole chair can be reassembled in the same way. Once the glue had
set, Kevin filled some gaps left from missing pieces of wood by using Selleys
Plastibond. This is a polyester resin thatís ideal for the task, because it sets
hard, sets quickly, and accepts colouring Ė so you can match it to the timber.
Once itís set, shape it with a chisel, plane and sandpaper.
Kevin finished the chair with wood oil, and itís ready for service again.
||Kevís Tip: Colour the Plastibond filler slightly darker than the wood. It will
lighten as it hardens.
Selleys products are available at all good hardware stores.
