Hi aztd - looks like no one's responded yet, but I have a couple thoughts anyway - seems like that might be a little difficult to build "home-made" and have it be attached rigidly enough to withstand the forces that are going to be pushing against it without some real engineering - I've had some standrd fences slip on me when I thought they were pretty well locked down (I assume you mean a lateral clmping mechanism similar to some of the clamping straight edges and guides that can be bought where it's gripping the edges of the table as opposed to clamping in a vertical direction). For myself and my limited brainpower, keeping things simple has generaly worked best for me, but I'm also not all that imaginative. I'm not sure what the advantage would be of having a Biesmeyer type fence on my router table - are you thinking that it might help with making minute adjustments? - I generally just pin one end of my fence and make adjustments by pivoting the other end and clamping it - if you can picture it that way, fence-to-bit adjustments can be made that are pretty durn exacting - even if your fence is nothing fancier than a 2x4 . That being said however, if you come up with a homemade way to build one like that without having track rails or other mechanisms in your way, I'd really be interested in seeing it. Wasn't intending to be discouraging and there's certainly pleasure in simply creating something like that. If you try it, please share the outcome with us.
