When I doubled the size of my table saw by adding a second table top from another old saw, I had a hole in the middle of the added segment where the saw blade insert would have gone originally.
I thought about making a blank insert to fill the hole, but then I thought I could make it more useful but using it as storage for my stock insert, which I will use when I need to make beveled cuts (my zero-clearance insert prevents tilting the blade, so I need to swap the insert if I need a beveled cut).
Since the stock insert is a relatively thin piece of metal, I partially filled the hole with a piece of 1/2″ plywood so the insert would sit flush with the surface.
I had to drill out the plywood under the insert’s holes because the underside of the insert is bent downwards around these holes (basically the negative of the countersink in the top of the insert) causing the insert to sit a little too high.
After drilling the holes, the insert sat a tiny bit too low, so I shimmed it up with a few pieces of duct tape. I also used a Sharpie to color the wood under the openings in the insert, just to make it look a little better when it’s all put together:
Now I have a place to keep my stock insert, and I don’t have a big hole in my table saw top:
Now I need to make something with the saw…
