> Is the burr comb problem with the plastic frames a spacing problem or > is it a material problem? This was what I was thinking. I never noticed that the frames sit any lower than wooden ones. Pierco frames aren't as wide (somethink I like about them) as wood, but again, I never noticed that the frames sit any lower. I didn't chime in because I wanted to check before I wrote and haven't had the time to do so. I ALWAYS have problems with burr comb on the top bar of Pierco frames - a main reason I do not use them. I have heard it said (but I have not tried) that a piece of masking tape on top of the frames will thwart the burr comb problem. If that is true, then it speaks to the material problem which Blane suggests. Personally I'll stick with wood. Aaron Morris - thinking SABA Seminar at UAlbany tomorrow.
