@Cheese Using Whiteside surface planing bit. In terms of the end result it frankly isn't all that different or better than the 1 1/2" straight bit I was using before, but since it is less massive, there's not as much anxiety using an extender chuck and plunging it so deep.
Another thing I like about the Woodpecker mill is that the setup is really easy. The crucial distance you have to match is that between the carriage and the rails, but that is simple to do by just using the carriage to finetune the position of the rails before screwing them down to the bed.
The main question about the woodpecker jig vet I suppose most people have is the value proposition, since it is ridiculously expensive. I don't really have an answer for that, and Im going to have to do a bunch more slabs before I can come to a firm conclusion. Giving my space constraints, where i needed somthing that could be easily setup, disassembled and stored for reuse, while also delivering precision, and the fact that I wasn't deferring the purchase of another more essential tool by getting it, I'm ok so far with the purchase. It certainly made the difference on the Elm Table I just finished, where i was able to remove the cupping that had developed in the top -- and I only had to remove about an 1/8 " , and so was able to deliver the final result still within spec. I don't think I could have pulled that off working by hand.
I'm also interested in your thoughts on the Woodpeckers setup.
What planing bit are you using Edward?
