Topic tags/keywords: jig tablesaw clamp blade router

I need to put slots (through mortises) in basswood rails which are anywhere from 18” to 108” long, 3/4 thick, and 1 1/2 to 5 1/2 wide. Slots are 1/4”x 3”. 2 to 4 per rail. The slots are located by the ends and occasionally in the center if the rail is long. They need to be repeatable and done 20+ an hour. This is in a production environment. I was hoping a woodrat might work, but doesn’t seem like it will.

In essence, I need to cut a bunch of through mortises quickly and somewhat precisely in a way that is repeatable and straightforward.

Any thoughts?

Sounds like you need a chain mortiser. Here's one.

A custom-built CNC horizontal router would do the trick. One two axis movement required so it’s not a difficult build.

Slot mortisers as others have mentioned are also well-suited for this type of work.

Can you get router bits or mortising chisels that will cut 5.5” deep mortises? And why would you need CNC, that seems like an unnecessary complication.
