   I asked this question a couple of years ago and didn't receive any answers, but I'm still interested in making the conversion. If someone gets back to you via email, would you let me know? Jim

   Check with the appropriate forum on http://www.woodweb.com

   Professionals would be more inclined to use the Esta knife system.   I'm betting XL is used in more stock knives on jointers and planers. We use XL on short run profiles on our moulder because because it's easier to sharpen. M2 lasts longer and is harder.  According to Esta they use an M2 steel and M42 is available which is cobalt and harder than M2

   I recently installed dispozablades on my Parks planer. I then proceeded to plane more than 1000 bd ft of assorted walnut, cherry, red and white oak.  I then turned the blades over, and have been using the planer for sizing lumber for projects.

   Overall, I am happy with the system.  I do not use posi-set.  I find that I still have to check and to "tweek" the final blade height, because tightening the locking bolts can cause the blades to ride up.  Replacement is about as much trouble as shifting three conventional blades. 

   I feel it is a real advantage to have really sharp and straight blades available for replacement whenever I need them ( I bought an extra set of blades - 2 extra sets of sharp edges).    Plus, it is feasible to switch to a still-usable-less-than-perfect knife set for rough work, then change back to the good edges for projects.

   On the (slightly) negative side, these blades are not as rigid as the original equipment blades for my planer.  This has not been a problem, but I suspect that wear and damage resistance are less robust, and controlling blade projection above the cutterhead is more critical.

   Did you get Dispozablades for your planer?  If so, how do you like them?

   Wil, no I haven't tried them yet and you make a good point about the blades riding up while tightening. I may try them in the future  though.
