Best way to repair crack in this wooden stud

[ph659266]

Hello,

I have a small query... A couple of days ago, my wife and I bought a used sectional door. Today, after we washed all the parts for repainting, we found a long crack in one of the beams. These are grooved, so I think it might not be easy to just go out and buy a new one.

Thus, my question is: What is the best way to save this beam? At home, I have wood filler, wood glue, and long wood screws. Besides these three methods, is there anything else you would recommend?

Thank you very much in advance!

Best regards, Patrick

Wood glue and screw.

I would have sawed in from the left at the end of the crack and then glued the wood piece back with waterproof wood glue.

I had widened it as much as I dared and pressed in good wood glue and then clamps.

Cutting in from the side might not be a good idea. You will never be able to glue end grain with any strength retained and will end up with a weak point. Better in that case to split the wood completely and glue the entire piece. Or do as @Stefan1972 wrote and widen it, press wood glue in as well as possible, and clamp it.

Yes, exactly as mentioned above. Either break off the cracked piece and then glue it back or try to widen the crack as much as you dare (which might then become option one) and try to get glue into as much of the crack as possible and put it under pressure. After gluing, secure with a screw from the thin part into the thicker part.

How should it be positioned? If it's possible to place an extra stud behind, you can not only glue it but also screw it to the stud behind. Otherwise, maybe there's room for a piece of plywood behind?

How should it be fixed? If it's possible to attach an additional stud behind, you can not only glue it but also screw it to the stud behind. Otherwise, maybe you can fit a piece of plywood behind it?

It's the beam that should be above the door. Definitely a good idea that I will keep in mind when the work is to be done!

Yes, just as above. Either break off the cracked piece and then glue it back, or try to widen the crack as much as you dare (could then become option one) and try to get glue into as much of the crack as possible and clamp it. After gluing, secure with a screw from the thin part into the thicker part.

I consider screwing it to be completely unnecessary and perhaps even detrimental in terms of strength. When you glue a crack in the wood, the joint will be at least as strong as the wood was originally (stronger really because, after all, the wood has cracked).

Screws can be useful in situations where you cannot clamp the pieces together in another way. When building speaker cabinets, it is common to screw while the glue dries and then remove the screws so they don't move and ruin the surface finish after filling the holes.

Thanks, so clamps are recommended as Stefan1972 also pointed out?

Yes, you need to get everything under proper pressure for it to turn out well. It is recommended to use a couple of battens (or similar) on the sides to spread the pressure from the clamps over a larger area, especially where the cracked piece is thin.

Expand it, using wood glue, apply clamps and then pre-drill and insert 2-3 screws, then it will never break there again.

Expand, with wood glue, use clamps and then confuse and insert 2-3 screws, then it will never break there again.

Guess you mean pre-drill. I still claim that screwing is unnecessary, and if you even have to pre-drill, it will weaken the rule. I believe it will hold anyway, but I wouldn't do it. The glue is strong enough.

 

[Johan456]

Yes, I changed it. The glue holds securely, but that's how I would have done it.

Guess you mean pre-drilling. I still claim that it's unnecessary to screw, and if you're even going to pre-drill, it will weaken the rule. Enough that I think it holds anyway, but I wouldn't have done it. The glue is strong enough.

Possible pre-drilling and screwing do not weaken...

The glue is certainly strong enough, but screw-gluing is actually always stronger as you simply get the advantages of both without any new disadvantages, provided it's done correctly.
