Well the thing is, this is only wide enough to do edges. I suppose I could flatten a wide board with enough practice. I don't have any idea how to use these other than to take a hump out of one spot on a board. I used to have a cheap planer, like the Harbor Freight models but another off brand name, and I damaged one of the double sided blades. So I took the blade out and flipped it over and NEVER could even figure out how to get it reinstalled again, let alone aligned. It was a monumental hassle! It's like you had to hold all the parts aligned with one hand while sticking a wrench in sideways to barely turn a nut with the other, and before you get it snug something slips and it has to be taken out again. It had another long piece that ran longways with the blade to pinch it in place, some kind of shim I guess, and then had two screws in each blade. There was a groove in the slot where the blade sat that had to line up with the shim piece just a certain way and it was impossible to do without 3-4 hands. I only have 2. After multiple attempts over several months I finally gave up and threw it away. I'm not sure how this one will go but I'm not up for another hassle on a tool. This one is also the type that needs oil added to the motor. I really just don't want to fool with it. I bought it before I even knew anything about what to buy for woodworking.
But, yes, those Craftsman blades look like they might fit it. On the plus side these blades have the nuts fully exposed so it looks like it would be much simpler to change one, however, realigning it to cut right, that is another story. I have no idea how this would go. The blades are single sided if that matters.
This thing originally came with a wooden case that had fabric on the inside. It was in pretty poor condition, the fabric was hanging in rags inside. There was no instruction manual. I tossed all that out and kept the tool only.
