I am currently using a 3/4” straight bit for my router planning sled. I was thinking of buying a 1 1/2” or a 1 1/4” mortising bit to use instead. Does anyone have experience with this, are the bits too big? Also would you recommend Freud or Amana bits? I like the Freud bits I have but don’t have any experience with Amana.

I would recommend getting a bowl bit. it’s also 1 1/4” (I believe) but has rounded edges as opposed to the mortising bits.

I personally have the 1 1/4” mortising bit, and while its faster to plane down an end grain board than it would be with a 3/4” bit, the sharp corners leave ridges along the length of the runs which then needs to be cleaned off. the rounded bowl bits leave a smooth transition at the edges and eliminate those lines from what I’ve seen.

Good question, Chris. I used a 3/4 straight bit to flatten an end grain cutting board in a router sled. It worked fine, but like PurpLev states, it left some markings that needed to be sanded. If you go with a bowl bit, let us know how it works.

Well I just ordered a Whiteside 1 1/4” bowl and tray bit. Maybe when I get it I will take pics and explain the process of using the sled.

PurpLev is right on. When David aka patron was here last fall, we made a planning sled and had to use a one inch straight bit. I have since ordered and have on hand a inch and a quarter bowl bit and it is superior to the flat bottom straight bit. You will like this much better. And I have had very good success with MLCS bits. Give them a try. Rand
