Topic tags/keywords: question

My wife has a bedside table that her grandfather made for her, years ago. It is a good example of what happens when wood moves…as you can see the trim has pulled away from the top. I’d like to repair it; the easiest way would be just to cut the trim off and replace it; the problem with this is that I don’t think that I could match the finish of the new trim with the rest of the table. Of course I could strip the existing finish, but that seems like a PITA…any ideas how I could fix the existing trim? I’d thought about using the bandsaw to trim the piece back that has expanded, then re-glue and clamp…

It looks like your trim is letting loose and is too long, pry the trim off , re-miter the corners, glue and CLAMP. You should be able to reuse the trim if you are careful prying it off.Work slowly from loose end.

You can remove the trim and shorten it, but when the humidity increases the center is going to swell up again and the trim will have gaps at the end. If the wood was rather green when it was built, it might not move as much. This design is normally used on plywood or veneered tops. Solid wood is going to move with the seasons and there’s really nothing you can do about it.

Is that top solid wood or plywood? If it is solid then I would remove the trim entirely and rout a profile around the edge of the table and call it good. Unless that is plywood, you will continue to have corner separation issues with that trim arrangement no matter what you do.

thanks guys; I guess this is a good example of why you shouldn’t put trim around a solid wood top. There’s not enough of an overhang on the top to rout a new profile in it, and it makes sense that if I fix the trim, it will continue to separate as the top moves seasonally. I may have to replace the top and refinish the rest of the table to match.

Rob,
Thanks for posting this. While I have never had this issue (haven’t built that much stuff yet), this has been quite the educational moment for me. Great tips and explanation guys!

Another option would be to do a breadboard type trim. One way would be with a wood to match, or you could go a completely different species. (not sure if you’d need to lengthen the width or not)

Breadboard type ends are meant to take the end grain movement.

Cut a rabbet on top of the molding (trim) and let the table top free float in it.
Or, if the trim breaks as you pry it off, make new trim. Then cut the rabbet and make a new detail.
I like that top and would save it.

If it is yellow pine, it was probably just wet when he got it from the yard, once it dries yellow pine is pretty stable.

If it is cypress, it will continue to move, one of the problems with cypress is that it’s kind of like a sponge and soaks up humidity, which is fine for alot of places with constant low humidity, however where I live, it’s not so much a good thing :/

Looks like that was done with wood that wasnt fully dry.. I would do as other suggested, take that long piece off and shoot off the end until it fits and put it back.. I would hazard to bed that it won’t do too much movement if the table has had some time to dry and stabilize.

Since your in a nothing to lose type situation so to speak I would offer this suggestion.
Try disassembling the table and seal all the edges and bottom with sanding sealer. This won’t completely stop wood movement but will lessen its movement quite a bit.

If the end grain is not sanded very smooth, sand it to a smooth almost glass finish to help in sealing the end grain. This will help to tighten up the end grain pores to help the sanding sealer to seal the end grain.

Having worked with yellow pine a lot and sealing all the surfaces I have found this to work quite well for me with minimal wood movement in my projects.
This way you can reuse the trim and will save you from trying to match the finish when reassembling the table.

This top is made of flat sawn ash and guessing at the width of at least 24”, it will move about 1/2 and inch as the season cycle (worst case).

You might be able to saw through the miter to shorten the length of the problem corner. If it has nails you can use a hack saw. I agree that this top should have finish on the top and bottom,if you remove the trim I would seal the edges also. I also agree with the Idea of bread board edges.
