Shop made wooden insert does a better job of keeping dust below the table.

Made a short video to confirm the difference: https://youtu.be/blBJ-EKZb7c

The bottom of a SawStop insert is difficult to replicate in a shop made wooden insert.
If we limit the application to vertical cuts, and exclude maximum height of the blade, then the insert becomes much simpler, and still works most of the time.

Quick to make and low cost so you can have one for each dado width. Images of drilling diagram below.

Looking at a similar issue with my new Harvey. That big rear slot to clear tilt does not “scrape” the airflow. I have some prototype ideas how to deal better below the table. Can’t experiment until my DC gets here.

I had ZCI’s with shorter slots on my old saw just for that. Eventually, they would up as full length.

Those look really good. Have you noticed any issues with them since they don’t lock in the back?

Another insert is one of the reasons that I’ve been delaying on buying a dado brake for my SS.

Have been using the shop made wooden inserts for a while with no problem. Most saws don’t have a locking in mechanism for the insert. My previous Rockwell saw, that I used for 30 plus years, just had drop in inserts and I never had a problem.

That’s good to hear. My dust tube was clogged not too long ago and I was getting a ton of dust out of the top of the insert. Finally something clicked and I figured out why and was able to clean it out. A closed insert like this would help me out since I only use a shop vac.

The dust comparison video was taken with a shop vac as the dust collector. I am planning a proper dust collection system but have been getting by with the shop vac for a while on SawStop ICS. Get a lot of sawdust build up inside the cabinet but that is easy to clear out.

Have your say...
