Default Some Thoughts on Fence Control

I've begun doing a couple of things that have helped me fine-tune fence placement and thought I'd pass them on. Now ... I'm pretty much a novice and maybe everyone's already doing this and saying "So what else is new?" but for me it was a big move forward (remember What About Bob? - baby steps, baby steps), so for what it's worth ...

1. I've gotten away from worrying whether or not my fence face is parallel to the table, to the point where I've installed a pin through one side of my fence base and will sometimes peg it in place and then fine-tune my fence location by moving only the other end. What this does for me is to give finer incremental adjustments at the bit location when trying to "sneak up" on a cut - it's more of a fine pivot rather than a sliding adjustment so it's easier for me to control. 90% of the time it doesn't matter whether my fence face is square to the table or miter slot, and if I AM using the miter, I just put a square against the fence and rotate the miter head to be true to the fence's angle.

2. For those like me whose fine motor skills are challenged, there are some bits that are a real chore to get setup - both in height and fence position - a locking miter bit comes to mind. Set-up blocks are great, but you'll still have fine-tuning to do. Now you've gone through all the trouble, gone through a billion test pieces (more fodder for the fireplace), and have finaly gotten it fine tuned and the fit is perfect ... but you can't be taking all that cut in one pass or you'll rip out, or have to go too slow and burn the workpiece ... all the usual horrors of taking too much material in one pass (not to mention the safety issues). But I don't want to lower the bit and mess up the set-up (for that matter, with a lock miter you can't slide up on the height). What I used to do was try to mark the fence location on the table top, move the fence forward for a shallower cut and make several passes while gradualy returning to my marks .... this was close, but way less than the perfect fit I had struggled for - I was never quite satisfied. Well, remember the pin from above? Nowadays, when I've got the final fence position set, I just clamp a stop to the table top BEHIND the fence on the end opposite the pin, then pivot the fence shallower, and proceed to make passes gradually pivoting back till I hit the stop. Perfect repeat every time. If I'm not using the pin, I just put a stop block at BOTH ends.

Like I said, I'm a novice and maybe this is old news for everyone else, but for me it's helped a lot and I haven't seen it talked about - so maybe it'll be of help to someone else. May the chips fly where they will! ;-)

Marc Sommerfeld uses a similar set-up on his "ultimate router table". If you really want to see a Precision Router Fence see Pat Warner's fence at his web site or in some of his books. The first fence I ever made I copied from Warner's $2.00 fence, a bolt through one end of a board and a clamp on the other. What ever works. Have fun.

Regards

Jerry

I do believe that simple is best - I had to go with the clamp on board routine the other day when I couldn't move my fence far enough away from the bit - I took off the fence and just grabbed a piece of 3/4" oak and clamped it on. Pretty Hi-Tech, huh?
I'm also looking at making a new table and fence, so I'll have to look into this "ultimate router table" you mentioned - is this a plan, is it a table that's for sale or is there a web site? I'd like to take a look at it. I've been taking my time planning and am looking at examples and ideas before I start.
Thanks,
Gil

Looks like a "m" was dropped from sommerfeldtools.com

I checked into the Sommerfeld web site (you're right Ed, two m's) - didn't know that was CMT bits - I assume you're talking about the Industrio line of tables? A little pricey, but I did see the reference to the pivoting fence concept. I'll have to see if there's somewhere in the Chicago area where I can go to see one. Thanks for the link Jerry!

Intresting pecause I just adopted the same fence method. I had cut ,sanded,screwed,nailed. You name it bulding a sliding fence on rails on both sides of the table. It was a total disaster. I started thinking what the hell why not simply pivot one end and clamp the other and do the measureing from the bit with a square. Sure enough enough iot works great. Now I plan to build a new table and hope to get lots of help from all these pros.

Ephrem: hang the pivot point. Just clamp both ends and be done with it. What is critical is that the face of the fence toward the workpiece is perpendicular to the table surface. That is your only worry and a jointer handles that nicely.

I have 2 of those tables & they work great. The fence is capable of being used both ways but I have only used the pivoting option. You can also use the top from both sides. I have the t-track on the back side of the fence because I don't use sleds that need to ride in it & using it from the other side you have more table in front of the fence for larger material support.

Have a nice & safe day!
