I know this is a rather simple project that many have already done, but since I had a pretty close call recently due to using the stock insert while cutting some small pieces I figured I’d put this up just as a reminder.

If you are cutting small pieces, make sure you have a Zero Clearance Insert so pieces don’t fall through, get wedged, and get thrown back at you… Oh, and when the wood falls through, your push stick will dig into the blade quickly and get thrown back into your hand also…

Here is a link to the video I made of the process.

I recently made one too. I like the white look of yours. I haven’t cut the slot in it just yet, as I have a factory made one for my default blade. I’m keeping my shop made one around as a spare.

When cutting small parts, please consider making a cross cut sled. Its much safer and you get an automatic zero-clearance insert built right in :-).

I agree with Matt, use a cross cut sled, much safer.

When he said “small pieces”, I’m pretty sure he meant thin pieces, which can and will get wedged between the blade and stock insert opening on most table saws.

That said, a zci is as much a necessity as a crosscut sled IMHO. :-)

I purchased my zci for the thin piece reason. I had a few thin wedge shaped pieces when cutting the pillar for my tower toy that either shot across the room or wedged their way between the blade and stock insert, which caused the blade the vibrate and gouge my wood slightly. Wasn’t a big deal to fix, but without that gouge, the cut was perfect for what I wanted.

On a personal note, once I’m through making a tenoning jig, a crosscut sled is next.

Yes. I was cutting long thin pieces from stock that was about 8” long and 2” wide. a cross cut sled would not have been very useful unless I installed some clamping hold down system as part of the sled.
