I finished this fence riding pushblock I found in wood magazine. When looking at the item in the magazine it looked like a good idea. In practice I’m not sure I like it to much.
The idea is you raise the left so the material can slide freely under it and once you get to the end of the stock the flip down stop drops down and you can then use the pushblock to push the rest of the way through.
When using it a few test times (with the saw off) I found that I couldn’t just insert the stock and lower the push block on top of it like a featherboard. Doing this caused the stock being cut to drag the pushblock with it as it was being pushed down the saw. I had to raise the pushblock slightly above the stock, then tighten the screws to allow for the stock to slide freely under the pushblock.
Because of this, there is no downword pressure to prevent it from sliding away from the fence easily. On a 12’’ board I tested with the pushblock there was a 1/32nd of a deflection (one side was 1/32nd wider than the other) caused by the pushblock (Yes I double checked to make sure it wasn’t the fence, it has some deflection but it was only .003 of an inch, which is high by magazine rating standards I just haven’t tweaked my fence enough I guess)
Because the pushblock rides along the top of the fence, it doesn’t allow for vertical featherboards, or board buddies if you have them.
I dunno, maybe I’m doing it wrong but I’m not much of a fan of this pushblock.
On the bright side, I got a nice MDF template of a handle I can reuse!
