Hi All – Thanks for taking the time to read and hopefully comment on this. I am building an oak queen size bed. I have a couple gaps that are up to roughly 1/16th of an in wide. Most of the bed has really tight joints, but I goofed on two of the end panels. As stated, the gap is roughly 1/16” wide and about 10” long. It is a mortice and tenon joint and the gap is on the outside so I’m not overly worried but would like to make it as strong as possible. I hate to scrap them and start over and was in need some sort of filler, if possible that will stain up well. I don’t want to use store bought wood filler cause it never looks right when it is matched. I was thinking of mixing glue and saw dust from the project and filling it.

Is this the best way to go or are there any other ideas?

Cut a strip from scrap of like wood and gently tap it into the gap, hit it with a little thin ca glue.
Just my opinion but you know about opinions, they are like armpits, everyone has a couple but they all stink except mine.

Photos would help, but if you have a 1/16” gap and the issue is not structural, then doing a fill after you finish it will work. Go ahead and finish the piece however you plan to, and then fill the gaps. For a bed frame, I doubt you need to worry about wear on the surface, so a wax fill would be an easy fix. If you need more wear resistance then a hard fill will do.

If you want to go with the glue and sawdust method I suggest packing the gap with fine dry sawdust. Then in quick succession soak the sawdust with thin CA glue followed by the medium CA glue. The thin glue wicks quickly into the sawdust which allows the medium to flow more easily and solidify the whole thing. Let it cure then level the surface with a chisel, scraper or sand paper. Try a practice run on scrap pieces to see if you are happy with the results. I found using my orbital or belt sander that have dust collection bags is the best way to get fine sawdust for this purpose. I use this method all the time to fill cracks and voids in lathe turning projects. I keep a collection of different types of wood sawdust in plastic bottles just for this purpose.

Thanks everyone for the input. I was also thinking of fiberglass resin. I am going to try a few things today on scrap to see what I get. I don’t have any of the ca glue on hand and the nearest WW store is two hours. Going to call around and see if I can find some.

I agree with the first post, cut a thin piece of the original wood and ca glue it into place it will stain up nice. Another option is to just with it and build up some trim to mask it.

Hi All – I wanted to say thanks for all the help. I ended up using this stuff called “Tight Chairs.” I think it is basically CA glue. It was really thin, dried really fast, and worked like a charm. I filled the crack with saw dust/powder, then saturated it. After that I sanded it and a person can’t even tell.
