Lubricating Moulder Cutterheads for Easy Removal
Question
Forum Responses
From contributor T: I would use Woodworker's Dry Lube. It is a product that is sprayed on and dries to a very thin wax-like lubricant. The advantage of this product is that if it gets on your wood it won't mess up your finish later. It doesn't soak into wood like penetrating oils. You can get it from us (Lemmon & Snoap Co., Inc.). From contributor R: Lemon Pledge furniture polish works great. In my travels, I have left behind hundreds of cans at installations just to eliminate the problem described. Moisture left behind from the grinder in the bore of cutterhead causes the problem. If you spray a rag and clean each cutterhead and spindle before installing a cutterhead, I doubt you ever see the problem again. It also cuts the grime left on the spindle from the lubricant in the grinding coolant, which will make a cutterhead just slide on instead of being sticky. (I am sure all you moulder operators know just what I mean.) P.S. Keep those bottom cutterheads real sharp - they will eliminate a lot of problems in the finish. Poorly sharpened bottom heads can transfer chatter into the top finish head because the wood is trying to roll over the bottom cutter instead of cutting through it. Good luck. Try a can - inexpensive and it works well.
From contributor J: I use WD-40 and the only time I've ever had to use a puller is when I forgot to snug my top cutter nut. When I started the run, it tightened itself, of course, really snug. Now I double check before I turn the machine on. Hey, I also use WD 40 as my bed lube. Works better than some of the table lubes and much less expensive. No complaints from the finishing department. Good stuff - I buy it 5 gallons at a time. Would you like to add information to this article? Interested in writing or submitting an article? Have a question about this article?
