I bought a Delta Shopmaster 6" joiner from Lowes. Seems to be a weekend warrior grade tool. It does a fine job finishing the edges of plexi. However, I seem to get a couple hundred feet from the blade before I have to move the fence to a cleaner section. Secondly I hear diamond blades or perhaps carbide will give me even a cleaner glass like edge.
Secondly, If I have to edge anything longer than 4 foot, the short table is a hindrance, I can graduate up to a better model if needed. Thanks!
