I can cut some of this stock away, but I have a Question…. I saw someone on line that used Epoxy on cracks to seal them, WILL THAT WORK. I will be using Mortise and Tenon joint on these

Cracks usually point that the wood has dried too fast, or unevenly and the grains are pulling away at some points. If you’ll “glue” a crack back together with epoxy and the wood still has stress in it – it could very well crack in another spot. If the wood is already stable and fully dry it’s worth a shot. although depending on where the crack is and how bad it is, it may not even be necessary.

I can’t see from these pictures, but It seems like you did not mill (joint) these boards prior to glue up. make sure you do joint and square up all those glued up parts for the legs so that when you make the joinery and put it all together – it’ll be nice and square which will make everything much easier on you in the long run.

Yeah I was wondering if you milled the glue surface too? If you didn’t, not only can you have a squaring issue like purp said, but most likely your glue joint(s) will fail…

Thanks guys, The boards that are cracked were not the boards that were glued. the glued boards were milled smooth on the glue face. Not sure what you mean by “Mill joint” should I have notch and grooved these? They did move a little when I tightened them down But I will plane these square when they are dry so that when these sit on the floor one board will not be hihger then the other putting more pressure on one one of the boards glued.

The cracked boards are fully dried I will cut them to length needed and see if the cracks have reduced in size.

QUESTION when glueing should the surfaces be Smooth or a little rough so the glue holds

ScrapArt, i think they are referring to planing the glue surface flat prior to glue up so you have two flat surfaces being glued together. The cracks you talk about amy open up over time depending on the stress they are put under. It looks like you are using reclaimed lumber, which is usually dry as a bone. IMHO, i think the cracks will be fine and filling them with epoxy is a pretty good idea. Ive worked with a lot of reclaimed wood that has cracks, nail holes, and all kinds of crap in it without any problems so far.

Good Luck .. ill be keepin an eye on your bench build.
