Discussion Overview

The discussion revolves around alternatives to featherboards for use on table saws, specifically focusing on devices that can hold a board against the fence during ripping operations. Participants explore both motorized and un-motorized options, considering their effectiveness and potential design challenges.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about simple devices that can replace featherboards, suggesting a motorized device that uses friction to hold the board against the fence.
  • Another participant proposes the idea of a top-mount featherboard but notes that it primarily presses the wood downwards rather than against the fence.
  • A participant questions the effectiveness of an un-motorized rubber wheel at an angle, expressing uncertainty about its functionality.
  • One participant shares their experience with motorized versions, confirming that they can push the board into the fence while also pushing it into the blade, and suggests that a non-motorized version might have similar effects.
  • Concerns are raised about potential marks on the wood from the rubber wheel, although another participant recalls that the soft rubber typically does not leave marks.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of various designs, particularly regarding the functionality of top-mounted featherboards and the proposed un-motorized wheel. The discussion remains unresolved with multiple competing ideas presented.

Contextual Notes

There are limitations in understanding the mechanics of the proposed devices, particularly regarding the angle of the wheel and its impact on the board's movement. The discussion does not reach a consensus on the best alternative to featherboards.

Are there simple devices that can be used on a table saw and applied to the top of the board to hold it against the fence - thus replacing the function of featherboards ?

When ripping a board on a tablesaw, a featherboard is often used to hold the board against the fence. A limitation on featherboards is that they must be used on the in-feed side of the process because if they were placed against the edge of the board on the out-feed side they would press the two strips of wood that have been cut apart back together and pinch them onto the blade.

I can visualize a motorized device that presses a spinning wheel against the the top of the board and uses friction to push the board against the fence. That may be simple from the commercial point of view, but from the "home owner" point of view it would useful to have an un-motorized contraption. Do such designs exist?

When I visualize a un-motorized rubber wheel pressed on the board with its axle is at some angle to the plane of fence, I don't have an intuition about what it would do.

How about a top-mount featherboard?

A top mounted feather board only presses the wood downwards, not against the fence.

Great question. I think it might work. If a car skids with the front wheels locked it can't steer, but if the wheels are allowed to rotate (even if under rotating) the car can be steered to some extent.

You might end up with marks on the wood?
 
I've used the motorized versions and your intuition is correct. They are at a small angle so that the wheels drive the board into the fence while at the same time push it into the blade.

I think an non motorized version would do the same. They don't mark up the board as far as I recall, they're made from a fairly soft rubber so that they grip.

Google table saw power feeder for some examples.

Ah. I missed the part about the wheel being angled.
