The sketch shows a proposed leg fabrication; it is for a small workbench I’m building. I want to rip the 1×2’s from 2x stock, but I know that it will not be straight once ripped from the mother board. Is there a way to maintain straightness, or will the legs remain straight once glued up?

Wow, I don’t understand this at all. Why are you gluing that from four pieces, and what’s with the rabbets? More info please.

You’ll generally get better stock from a 2×12 than a 2×8, let it dry a nice long time and there shouldnt be much movement when you cut it. A little bow won’t hurt anything, the box construction of the leg will pull it out.

The rabbets are for the front, back and side panels of the bench; all of which are 3/4” thick. This is the only way I can get the 2-1/4” dimension I want. I intend to rip 3/4” wide strips from 2×12 lumber and glue them up as shown. Once glued, I will then cut the 3/4” wide by 3/8” deep dado’s to accept the 3/4” panels. I hope this explanation is clear.

Thanks for the tip. I will use a 2×12. A 10’ long piece of 2×12 will supply all I need for 4 legs. As I mentioned before, this is for a small workbench that will be used for hobby use, like building models, not for heavy pounding on. Once done, it will probably go into the house and sit in a corner. All heavy woodworking is done outside in my 1200 sf shop.

Okay, so the rabbets won’t be there during the glueup phase, OK I follow now.
Yeah I wouldn’t do it that way. Just glue boards together face-to-face to get your required thickness. This will give you a solid leg. Then cut the joinery afterwords.

If you make the parts a little oversize, you can re-joint things straight and square after glueup.

I agree with pintodelux on face gluing it up, but if you need to do the 4 piece glueup for the hollow core keep in mind that construction grade lumber is often dried fast and has internal stresses. You may need to mill it over-sized and let it acclimate.

Any reason you cant use 3/4 plywood?

Since all of the pieces are 3/4” why not make from 3/4” stock?

Bondo +1

3/4 FAS ( First and Second ) graded stock and you’re good to go.

Alder seems to be the crowd favorite.

I was actually wondering about 3/4” plywood. Nice and straight and stable.

Just another thought: Cut down a 4×4 to size is an option, no?

I agree that face gluing up 3/4” stock would be a better way and easier way to do it. I can use 1×3’s, rip them down on both edges to 2-1/4” wide, then glue 3 of them together or glue first and then rip. I can see they will come out straighter. Plywood is also a good option. Thank you all.
