I'm looking to make a massive roubo for my shop and struck a bit of luck when an ad came up on CL for some 100 yr old, hand hewn oak beams the seller was getting rid of for 5bucks a LF. The beams were stored inside a barn adjacent to a farmhouse (pre civil war). It was dark in the barn and while I picked the beams out with a flashlight I failed to notice the small 1/32-1/16in holes covering the majority of the pieces until I got home and unloaded them. The beams are about 8in by 14in and appear structurally sound but I'm uncertain whether the holes are wormholes or termites. I have yet to mill them up so I do not know how deep the holes are but I'm concerned I made a foul-up and purchased termite ridden beams.
Is there any way to differentiate wormholes vs termite holes? Is the wood still usable if they are non-active termite holes?
Ill try and post some pics for your review.
Thanks in advance for any replies.
