2 MagJigs, + 1 LS Positioner =

More detail provided in this article on my blog, just thought someone might be interested...

Stuart, I have done a similar thing with my Incra LS on the tablesaw, although I have mounted it with bolts though the normal mounting position, and I don't use the Wonderfence.
I'm surprised that you haven't had a reaction regarding safety and kickback yet!

Didn't include the other photo from my blog, nor the associated text.
I just didn't get around to removing the Wonderfence before the photo - it is not recommended for saw operations."Clear, Ease Springs"

Yes I have the same problem with this as I did with Big Shed's set up. I think having the fence fixed in the centre, rather than at the edge of the table is not a great idea.
However, if you feel safe with it, then go for it, they're your fingers"I don't practice what I preach because I'm not the kind of person I'm preaching to."

It's sometimes a struggle to be consistent but I've got to make the effort

Interesting Silent - Remember reading your comments now.
I wonder...... a MagSquare attached at either end of the fence could be used to lock the fence to the table once the positioner does the...positioning.
One thing about the Incra TS version - the rail is significantly longer than on the 17" (2 - 3 times longer), so any racking is magnified significantly.
At worst, the pressure is against the fence, so any racking will have the effect of moving the work away from the blades rather than towards it.
In the end, I'll be careful to assess the situation as I try it out, but I think that I will add the extra MagSquares at either end to firm up the fence."Clear, Ease Springs"

That's what we are referring to. Unfortunately my TS doesn't have two long golden anodised rails either side to be able to lock the fence to, so with Silent's concern, I'm thinking of using the MagSquares as a substitute.
Given their gripping capability, they'd hold sufficiently tightly to replace the channel lock I'm thinking."Clear, Ease Springs"

What I was concerned about was that if there's any racking or movement in the fence, you could end up contacting the back of the blade on the way through. I know that the Incra positioners are rock solid because I've got one, but I'm not sure how much effect adding an 8' lever to the equation would have. For small stuff it's probably not going to be an issue, but I think I would still be reluctant to try it.
If you look at the positioner rack as being a fulcrum, with the fence, and by extension, the board you are ripping, as the lever you can see that any movement away from the blade at the front of the fence should have an opposite movement at the other end, assuming that the fence doesn't just flex (I think that's the least likely thing to happen). So what's happening is that the rear of the fence moving closer to the blade, even by just a tiny amount, forces the cut edge against the back of the blade.
Pressure against the fence on a front-locking fence is always going to force the work away from the saw. This can result in burning on the waste and possibly inaccurate cuts if it's extreme enough. I have my rip fence set a poofteenth further away from the blade at the rear to avoid any damage to the cut edge from the rear of the blade but it still cuts straight. However pressure on a centre-locking fence would result in movement towards the blade at one end and away at the other - whether it moves closer or further away would depend on which end of the fence was copping the pressure.
How likely that is to happen I can't say, but I would feel better about it if the fence was locked at the front as you suggest. Assuming those magnets are as strong as you think, then it should be the same principle as the Incra TS fence. And what a lovely bit of kit that is."I don't practice what I preach because I'm not the kind of person I'm preaching to."

The distributor says that the big ones have up to 225 kg of force, one of them at each end of the fence should stop any racking movement, I would have thought...
