I'm cleaning up sawn edges on two-sided 18mm melamine faced MDF. I've got a Felder spindle moulder with a 3 wheel power feed. On timber and bare MDF, the power feed is very good. On this melamine the wheels seem to be slipping on the smooth surface, needing a lot of help in feeding and keeping it tight to the fence. Height of power feed or angle to the fence doesn't make much difference. Is this a common problem or am I doing something wrong?
From contributor K:
How old is the feeder or the rollers on it? Older rollers dry out and become glazed over, easily allowing them to slip. You can fix a board onto the shaper with coarse sandpaper glued to it to rough up the surface of the rollers. Also be sure to wax the table surface or use a spray coating like Topcoat to keep the table lubricated. I run a lot of melamine on the shaper with a feeder that's about 25 years old and original rollers. It's getting the same way so I spend more time coating with Topcoat to keep it going. I really need new rollers.
