For those of you that use the Woodmaster, Belsaw, Craftsman, Powermatic or Jet type molders, I have a few questions. I have both a Woodmaster 718, and a Belsaw 910, I’ve ran both as molders a fair amount. So I have a little experience with them.
When you guys run a casing knife that has a square form like a fluted casing knife, do you profile 3 sides with one knife or do you have your molding blank ripped exactly to size an only mold the top?
Some of the knives that I have currently have the profile and a wing on each side. So I rip a blank on the straight line rip saw at work about a 1/16th over. The problem is sometimes I get burning on the side of the molding. Obviously, I believe the knife is dulling, but the top profile is still in great shape. So I am considering knives that only profile one side instead of all 3. When you profile 3 sides at a time, I seem to get nice roundover edges. I think one edge profiling will not give those edges. I do run the molding through a mop sander, but I don’t believe it will round the edges quite like I want. With one sided profiling, you must have the blank exactly centered with the knife, but with three side profiling you can be off slightly.
I am also seriously considering buying the Woodmaster 2 knife corrugated head. I know that will help some. Most of my knives are from woodmaster, and I’m pretty happy with them. I just am trying to keep from dulling the sides before the top is dull.
Enough rambling. I’m just wondering what you guys do, and if any of you have the same thoughts.
