I'm giving some thought to making one and have been paper building it in SketchUp. I have never used one - nor even SEEN one - and would like to ask some questions to those more ecperienced with them.
- What is the approximate length of the angle iron part of the "T"...the part that rides along the side of the channel. I'm guessing about 12", does that sound right?
- On the outside - away from the saw - of that same piece there has to be some manner of adjustment to assure the fence is parallel to the saw blade. Logically, there would be a piece of light steel bar - 1/8"? - to act as a spring and a couple short, through bolts to act as stops when the fence is clamped. On the pictures I have seen there is precious little space between the saw and the saw side of this piece of angle iron. Does one adjust the stops from the rail side of the angle iron?
- The "T" also needs to allow for adjusting the fence so it is vertical. Again, from the pix I have seen, this seems to be accomplished by a couple of nylon or maybe UHDM bolts, one near and through each end of the angle iron so that they contact the rail, correct? My worry is that those might self loosen or tighten what with the fence riding only on them since the fence is constalrly being moved to and fro. Also, the surface area of those bolts seems rather small in relation to the weight of the fence and "T". Am I worrying for naught? Is there a better way?
I was considering using a 1/8" x 3/4" or 1" strip of oak attached to the underside of the angle iron, UHDM friction pads at the ands of the oak and set screws from the top of the angle to push the oak and its friction pads down as needed. Good or bad idea?

Thanks for your input/ideas; they will be - and always are - appreciated.
