Not really, set the zero clearance insert high so that it is perfect to the slider, it¡¯s just some jack screws. The few times I¡¯ve done a dado like that I use the shaper spindle, or a router bit in the high speed spindle as my machine is before dado capability.

Then your slider would have to zeroed to the cast iron or the zero clearance insert. I'll stick to my Freud for Melamine.?

Zero clearance insert would help.
I dont think anything is perfect..no matter what is used.. a lot of variables come into play..material, any sort of vibration, user error from feeding..etc.. it's all a matter of how OCD we choose to be..?
Would I like a perfect, flawless dado groove? Sure..who wouldn't,? but I've tried quite a few dado blades from Forrest, Amana Felder and a host of others and at some point all of them have a smidge of tear-out in the course of running 100's of board feet thru them.. again, it's all how picky and critical we choose to be. While I find the dado groove not 100% perfect, I'm not going to split hairs but I will keep trying to get it as close as humanely possible
All,
? ?This is a very timely thread.? I've CC'd Bill Wickett at Rangate so he can see what has been discussed.? Bill is working to develop a dado cutter for sliders and I'm sure he'd be interested in any recommendations anybody in this group would have to make a better cutter. Please feel free to email Bill if you have any thoughts.
Thanks,
That's definitely a better cut then your first picture but I'm sorry still unacceptable with those large chunks it blew out. For the price of the set not good and about as good as I could get back when I was testing. Feed rate definitely affects the cut and I've found with any cut in Melamine slower feed is definitely better with any Dado set.

Ok.. after my visit to the Felder office to have my dado blade checked out, here is what we discovered, and this is what we did to correct the issue.
First off, I learned, was to check to make sure the chippers and outside carbide inserts were seated correctly.? Mine were not..the outside cabinet inserts were fine, but the chippers were set in a way that the back end of them protruded out past the carbide nibblers just a whisper, but that's all it takes for them to create tear-out because they are catching as the "exit" the cut, forcing the fibers of the melamine outward, thus tearing out.? How we st these cutters was to place the dado blade flat on 2 separate pieces of melamine, loosen the set screws (the screws for the chippers are allen type screws and the carbide inserts are the torx type screws) (My high recommendation is to throw that piece of garbage torx tool that comes with the dado set in the trash and get the T-15 torx screwdriver) After you loosen the screws, press down so the dado body is flat and re-tighten the allen set screws.? Yes..I know, you can use a special tool and all that, but we didn't have that and this method worked perfectly fine. Test cut and check the results.?
We also discovered that a slower feed rate gave us a better cut after the bits were set.? My saw is set to run at 5500 rpm. Pictures show how we used the melamine and the results of resetting the bits?
