I need a featherboard idea


I have a planer\sander\molder\gang-ripper from Woodmaster. I need to come up with some enhancements to the feed table.
My Problem: When I gang rip, I am working from cheap S4S pine that can vary nearly a 1/4" in width. The setup on the machine has 1/2" tall poly fences at each side over a ploy bed. They work great when I am cuting molding from ripped stock that has a consistent width. However, adjusting the fences is a major pain. I have to stop the machine and drop the bed to access the fence adjustments. Not too well thought out but that's another story.
What I Need: I need some feathers\fingers\springloaded fence that is only 1/2 tall, about 24" long and I want to keep the width to a minimum to maximize the width of material I can send through. I want it to only be maybe 2" wide. I'll just clamp it off at each end vs using the holdowns of the current fence.
Picture adding a 1/2" tall fence to a typical planer at each side and having one of them be a feather board or spring loaded.
I'm looking for ideas about what material or what other type of setup might work. I'm thinking a spring loaded something but not sure of the best approach.

designed along the lines of a roller lifter or roller tappet for high performance cams in hot rods. See http://www.iskycams.com/racingcamseries.php the "roller series" photo. Rollers would have to be rotated 90 degrees for your app. but something like this would work.

I suppose it would work if engineered properly, but it sounds a little bit exotic. Lee Valley Tools sells various types which might be useful under difference circumstances.

I was familiar with most of these but they are all too big in one dimension or the other. However the fist one with the spring steel gives me some ideas thanks.

Vever thought of using lifters. Interesting idea. If I go witha spring loaded concept this might be the way to do it.

how about a springboard?
make a piece of baltic birch ply, 1/2" thick by whatever width you need to have it stiff enough by long enough to extend out of the machine far enough to conveniently get clamps on. also make a long thin ripping of some hard springy wood. make it a few inches longer than the BB ply. play with the dimensions until it has the springiness to bend twice the distance you need at the pressure you need it to be applying to the edge of the board. note that in this case, since you need 1/2" thick, to get a firm push against the workpiece the width will likely be greater than the thickness... I'll guess about an inch if the ripping is oak and the length is 30".... now lay the ripping on top of and flush with the edge of the BB and put one clamp in the middle, holding them to each other and to the bench. apply pressure to the ends of the ripping to achieve your desired curve and trace the line on the BB. unclamp and draw two new lines that approximate the angle of the curved line where it exits the ends of the BB. these should be maybe 3" long, falling off of both the ends and the edge of the BB. cut these two short lines. glue and fasten the ripping to the BB at these two cut surfaces, with the ripping spanning between them in a smooth arc. sand smooth and wax the convex face of the ripping.
to use it, slip a board to be ripped into the machine, up against the fence. set the springboard in place next to it, apply pressure towards the fence and clamp the ends.

Thanks, I think I follow. I'll have to try playing with this idea.

Ahh, I've seen comments similar to this before but never understood what the deal was. Now I get it.
I have the entire thread displayed as a tree in my reader so I can always see where I am in the thread. I guess if I didn't have that I'd have realized I am not leaving enough history forfolks to follow. And all along I though people just wanted me to conform to some arbitrary way of responding because they liked it better, not because it was required.
Thanks.

Even with the whole tree displayed, if the stuff to which you're /not/ responding is snipped then it becomes much easier to see the exact context in which you do intend to speak.
It's also a big help if you leave in the attribution for all the remarks that aren't snipped so readers like myself can look back to identify posts we might want to reread if we feel that doing so would help your remarks to make more sense and/or be more convincing.

adjustment.
It should be pointed out that many folks who abuse others on usenet also don't attribute. So by following some basic rules, you don't become identified with some real scumbags.
Which would be unfortunate. Because your contributions are appreciated.
