This is my first post on this forum.

My problem started when I decided to build another workbench. I have two and a table saw/router table that I can cover with paper and use for large assemblies. I am tired of trying to clamp stuff down to top of my primary bench. It is a flat top bench on rollers.

I got a “brilliant” plan to build it out of Douglas fir timbers since I have a friend that owns a logging business and lets me use his mill. I have about enough timbers to build the bench. We don’t have a lot of Douglas fir up here so he is really doing me a favor by selling me the logs. The logs were dead standing and have been in the logging yard for about three years. The timbers I want to use for the top has some substantial cracks. I have milled about as many logs as I feel comfortable using without taking advantage of the situation. At this point I am in situation where I use the timbers I have on hand or forget the workbench.

I have already purchased the hardware for, and built two tail vises, a leg vise and bought an end vise so I am at the point of no return. Mu only choice is to figure out how to stabilize the cracks.

The solution I have been pondering is filling the cracks with fiberglass resin and using dovetail keys to lock the cracks down. Maybe use long bolts through the table i really don’t want to fill my woodworking bench with steel bolts. I thought about epoxy until I priced epoxy. I have already filled the cracks but that doesn’t stabilize the cracking.

Any thoughts?

Thanks

Depends on why they are cracking. If it’s because they contain pith then good luck. If it’s because the ends weren’t sealed then I’d seal the ends and use Dutchmen across the cracks. But I wouldn’t have filled the cracks unless the timbers were kiln dried. Sometimes guys drill a hole at the end of the crack to prevent it from spreading further and plug the hole with a dowel.

I went out this morning and threw a straight edge on the surface of the timbers and they are heaving/warping in the middle. They are all the way through the timbers. I decided I just needed to bite the bullet and get new lumber for top. Problem solved.

Thanks for the advice.
