this is question that apparently varies considerablly with where you located. i got some 5/4 oak kiln dryed with a ebac system. some was stored inside after drying and some outside and coverd. first board threw a planer was smooth as silk, the rest came out less than that, asked on here what i had done wrong first time with this planer. NOT the first time i have planned lumber. the surface appeared as though you had laid a wet sponge on it to raise grain for final sanding. you WILL get slivers from this going against the grain and possible with the grain. i have had 2 mc test done on this, as has been suggested by those of you who are more experienced. the inner mc has been in the range of 10 to 12% the grain appears to be quit straight for the most part. got a opinion from a local cabinet maker in my locale (MI), and he said that the moisture was to high and that using it for panels would be hazardous with out drying further. so my question is the wood i now have is planned down to 7/8" has been stacked in the shop at 60+ degrees for the last few days while i have tried to get my ducks in row after the fact! do i get in touch with the supplier or do i stack it up and wait to use it another day. i have ordered additional lumber from another supplier to replace this that i now have. it is dried to 6-7%. will the 7/8' planned lumberr dry out further or does it need to go back the kiln? help and thanks for the advice
