Scoring the top ply with a utility knife before cutting or backing the cut with another board are two other common techniques to prevent chipping.

I've got the original IEEE-696 physical parameters, is that good enough for all modern N8VEM projects? Nice thick oak to be non-flexible. Thinking a short "U" with the board at the bottom and slots cut in the arms. Probably not coming up all the way on the side of the cards. That rather firmly bolted to standard rack mount shelf (heavy duty) bolted inside a steel rack case Poly coated on all surfaces for humidity stability and it'll live in a stable climate controlled area at constant temp/humidity anyway. Will live inside a ventilated steel chassis I have access to for EMI/RFI whatever. Thank you PCI/DSS financial regulations for forcing the production of cool little networking device cases with great ventilation and locks and access on all sides etc. I have more than enough 'leet table saw skills to pull this off. I'm thinking of two MBs one on top of another in the rack case. I've got 12U of space to hold these two MBs which will make a tight fit vertically but probably survivable (Will have to model that extensively, maybe I can get access to a 16U case...) Crazy? Sane? Better idea? I can' t be the first guy in 40 years to think of oak as a card cage material. Also are all the N8VEM cards under the IEEE size standards around the perimeter? I've seen some mighty full cards with "stuff" right up to the edge. Curious if anyone tried it and the tannins in the oak made their pcb corrode or poly finish sticks to rosin flux or something I haven't even considered yet. -- You received this message because you are subscribed to the Google Groups "N8VEM" group.
