treesner Posted June 5, 2019 Report Share Posted June 5, 2019 Hey guys I have a dewalt planner is it hard on the blades to run Baltic birch through it or things that are glued up? Quote Link to comment Share on other sites More sharing options...
drzaius Posted June 5, 2019 Report Share Posted June 5, 2019 Oh, yes! At least it is if you are cutting the glue lines. I once jointed the edge of a piece of BB about 3' long & it actually left the knives serrated. If you're just taking a little off the outside veneer you'll be fine. Carbide knives or segmented cutter head will stand up to that though. 1 Quote Link to comment Share on other sites More sharing options...
pkinneb Posted June 5, 2019 Report Share Posted June 5, 2019 I would not do it unless it was my last option had to be done...don't suppose you have access to a belt sander? That would be a better option. Quote Link to comment Share on other sites More sharing options...
krtwood Posted June 5, 2019 Report Share Posted June 5, 2019 Plywood, no. Regular wood glue is fine. Quote Link to comment Share on other sites More sharing options...
Ron Swanson Jr. Posted June 6, 2019 Report Share Posted June 6, 2019 My rule of thumb is no man-made wood materials though the jointer or planer, ever. Plywood, MDF, OSB, etc Quote Link to comment Share on other sites More sharing options...

I've never noticed PVA glue causing issues, but man, the stuff they use in plywood just eats HSS for breakfast. Quote Link to comment Share on other sites More sharing options...
