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.
I generallly just use the Belsaw for planing now. The Woodmaster is on it's way to becoming a dedicated molder. All the molding I have ran were with single knives in the planer head. For the most part I am pretty happy with my results. A little more background on the molder. I generally run the Woodmaster around 60%. Approximately 9ft/min. I have a melamine bedboard with T-tracks that hold adjustable wood rails. I have also done the motor on a hinge and single powertwist V-belt. I also beefed up the extension wings.
I don't really notice any chatter so I'm happy with that. When I run Poplar, sometimes I get light tearout. Then, I have to slow my speed down, but then I start to burn on the sides which leads to my questions.
When you guys run say 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 and 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. I am seriously considering do a side business with it, and the corrugated head would double my knife cost.
Enough rambling. I'm just wondering what you guys do, and if any of you have the same thoughts.
BTW, the main species I run is Red Oak.
