I feel "good" about the well documented technique of tapering table legs with two passes on a jointer. Video here (Glenn Huey, 7 minutes) for instance: https://www.youtube.com/watch?v=nZTXvsrzbSQ

The thing is I like small feet on my tables. I am looking at taking a leg from 1.50" square at the top down to 0.75" square at the bottom. 3/8 depth of cut to get it done in two passes.

I am looking at the $300 Porter Cable from the home store as entry level for me, with the 6Amp floor standing Rigid as the largest I can fit in my current shop at $800. Legs will be mostly white oak or hickory with some ash here and there.

My concern is if I have the depth of cut set at 3/8 inch I am going to have some vibration in the stock, especially on the third and fourth sides to get tapered.

If I am not overthinking this, where would my stop block go on the first and/or second passes with 3/16 depth of cut to have each side of my legs come out right on the fourth pass?

Thanks
