Yes, you must change grits. Work from 60 to 80 grit to thickness and flatten the board, and up to 120 to 150 grit for finishing. You have to leave yourself a little room to allow for use of the finishing grits, otherwise you might get things a little too thin. Its easy to figure out and, obviously, more material gets removed the rougher grit that you use. Definitely turn about 1/8” rotation at a time. It take a lot more passes than a conventional planer…but I find that to be quite okay. Your speed rate is fine. My belt feed isn’t speed regulated (older Performax 22/44), so my belt typically starts to slip if I’m going to fast. But most things still push though from 50 to 70 speed. Changing grits gets easier, but as Loren said, you’ll want to gang up your work so you won’t have to change them more than necessary. I find that the finishing grits work just fine, but I typically go over them with a scraper afterwards. -- jay, www.allaboutastro.com |
