The question I'm wondering about is how to attach the trim to the edge of the MDF. It's not going to be under a lot of stress, but I want something that will stay tight. I was thinking the threads on regular wood screws might be too fine to get a solid "bite" into the fiberboard from the edge. Would something like coarse thread drywall screws or particle board screws be a better choice? Should I put some glue on the trim also?
Any suggestions would be appreciated.
