Earlywood ring separation white oak veneer6/4
Attached are some images of rift white oak veneered doors provided by a general contractor that require finishing. The veneers appear to have unusually large vessels and visual signs of decay in earlywood. Machining by fabricator blew out veneer edges. I can't get a sound edge by easing tearout. Veneers are blowing apart during finishing. I suggested that the general contractor reject doors. He says to forge forward. Any thoughts on the condition of veneers? Do the defects appear to be of a bacterial nature? Do the vessels appear to be unusually large? I've never encountered anything quite this bad. Any thoughts or input would be appreciated.
What is "earlywood"?
Whatever you do I would write up a disclaimer about the condition of the veneers and that you will not guarantee the finish because of the unsatisfactory quality of the doors. Sign here.
Are they imported? Looks to me like issues at the veneer plant with dull knives, and then poor glue up. Doesn't look to be good glue contact. If you need to fix that in your finishing department, you'll have to charge them for filling with paste wood grain filler before finishing.
Most contracts tell you not proceed, I would put it in writing and get a waiver, make sure someone higher than a field superintendent signs it.

I agree with Rich, that is exceptionally poorly cut veneer. It shows signs of washboarding (knife pitched into the log too far), and is definitely what we term "rough cut" (to say the least) in the veneer industry.
By the looks of it, the log was way, way under-cooked, if cooked at all. You cannot cut White Oak logs into veneer without softening it up by boiling or steaming it through and through. Whoever cut that veneer had no idea whatsoever what they were doing. I can't imagine what the veneer slicer knife looked like after that fiasco.
Run, fast, don't touch it, that veneer could literally disintegrate over the course of the next few months. It is GARBAGE!!!
Thanks for all the responses:
Hard for me to say for a fact that it was only processing, could be more going on than I can get through a picture. But I know that if I had cut that veneer (or clipped it, or spliced it), it would have gone into the hog, rather than sent to a customer. Thick veneer is tougher to cut, but to me, sending out something like that to a customer is inexcusable! Just bad business; take the short term loss, don't lose a customer. That's just my two cents.
cabmaker, Earlywood is synonymous with "Springwood". Latewood is occasionally used instead of Summerwood. Not sure where and when these different words developed, but I learned them all in Jr High shop class in the 1970's in Ohio.
