Ok David, I just thought you were the one I was talking to about that at Camp ShopBot in Marion this last time. I did try it with a 1/4" deep x 1/4" wide wood strips in the spoilboard to seperate the zones a bit better. It actually worked well until I replaced the spoilboard a week ago and now get crappy results! I am going to check out the plumbing in the a.m. just to make sure the issue isn't something that simple!

To spin off what Mike said, only MDF made with formaldehyde glues will work for a pull-through spoilboard. Other glues are too dense. Weird, huh? But I have no idea how you can check that unless you can get an MSD sheet for your brand of MDF.

I have decided to give LDF a try. I am just concerned that it may be TOO porous. I'll post the results as soon as I complete the job!

I've tried everything I could think of, and my ultimate (hopefully temporary solution) was to drill/perf the spoilboard. My suction is back up were it was prior, but I'm not too sure how good of a long term solution this will be.
