If a part breaks, save the pieces - even the splinters! The Chair Doctor can usually glue them back together with an almost-perfect appearance. Making new pieces can be expensive. It is much easier, better, and usually less expensive to glue something back together than it is to make a new piece. We figure at least an hour of our shop time ($65.00) for even fairly simple new pieces, although sometimes it is still less expensive to just make new parts. The absolute best thing is to bring it to us when it is loose and before it breaks so we can rebuild it. But if it does break, like we said, make sure to get all the splinters.
The picture here shows the arm of an antique chair that is broken. Actually, it's not just broken, it's shattered! It had been repaired several times previously with regular wood glue but it didn't hold. There were also missing pieces, and by the time we removed the glue the gaps were even worse.
