I’d like to clear up a mental block that I cant get past! I picked up my Incra LS system a short while ago and am still trying to overcome being overwhelmed by it all. I understand that when making thru dovetails on the jig there is one and only one correct bit height, I get all that. However, logic tells me that bit height doesn’t matter when I’m making sliding dovetails. Am I correct on this?

Overwhelmed? Surely understated.

I’ve had mine for a short while and lovin it.

I trust you have the guide? I find it very clear and concise.

I love mine.

Of course I have the big guide and the instruction manuals for both the Incra fence LS and the Wonderfence. But no where in there does it cover sliding dovetails. I’m guessing its because the rabbet/shoulder cut can vary in width depending on your bit height. Anyway, problem solved as I spent the morning practice cutting tapered sliding dovetails. As Charles Neil likes to say, ”SNEAK UP ON IT” and that’s what I had to do and this is where the incra fence really shines. I was able to take 1/16” cuts on the sides of the tail until I got close and then started taking .005 passes and got it as close to perfect as I can.

The taper in the sliding dovetail allows me to easily slide the two piece together by hand with out binding until I get to about an inch from the end and then I drive it home with a mallet. Simple actually. Just intimidating

By the way timbetailor, that’s an awesome router table cabinet you built. I may have to incorporate parts of that into my plans!
