Good Straight Edge

No problem at all. Glad to be of some help. I have the 4 foot and 8 foot guides. The 8-foot guide has been used more lately, as it is an effective edge jointer. When I cut with it it tends to produce a decent glue-line (even at that length) although cutting wood that long sometimes will release internal stresses which cause subsequent crooking of the cut pieces.

I have a cutting guide similar to the one you have described, but it is about 20 years old. One day, I held the two sections edgeto-edge. What a disappointment; there was a lot of light shining through.

I hope your edge guides are better. I don't know of anything in the extrusion process that would necessarliy produce a straight or flat product. I suspect that there may be some post processing to yield a saw guide that is straight and flat. The bar stock in the home centers has not had any post processing.

Regards, Ed

Ken, Glad you found something that works. I live near both a J & L Industrial and a Production Tool store. I would probably have simply bought a suitable piece of ground flat stock perhaps .250 thick by 1.5" wide and been done with it.
