Has anyone seen the wood whisperer video on the VerySuperCoolTools extruded table saw fence. It's $250 complete and it looks real good to me. The VerySuperCoolTools site has details video to make your own so I plan on using my old welding skills to make my own. The 1 1/2" x 3" extrusion, locally, is $1 an inches so end product should be inexpensive.
Yes, by coincidence, saw that particular Wood Whisperer video 2 nights ago. At the time, I didn't place the fence as the same style as made in the AskWoodMan video series. I watched that video series (11 videos or so), I think about a year ago. Good tips.
Funny how that Very Super Cool Tools refers to the fence head as an original design, where as the guy in the video copied most of it directly from his beisemeyer fence head and fence, and drilled 3 holes to mount the extrusion. He never claimed it was an original design, but a copy.
I built one back then. Lesson's were learned. I found that there was some short coming in the beisemeyer design that I didn't like. I have design some of my own improvements on my fence heads since then.
The size extrusion you referred to is a 15 series 1530. Pat is right and that's where I got some of my extrusions and hardware. I got more from a friend.
I have a few fence projects also going on, just like you and Pat, but now with "L" square rip and miter/crosscut fences, using 1020, 1530 and 2040 extrusions. I see the 1530 as a good all-around size.
One of those projects was inspired by a friend that I recently talked into being a member here. He also has fence building howto's on YouTube. He's into his 4th complete fence system build... and they are hands-down mechanical and technical works of art!
