A good friend of mine picked up a lightly used Woodmizer sawmill this past fall. We were talking the other day, and he was trying to saw a walnut log. Had a real time getting through it we both figure he needs to attach the coolant tank. Woodmizer sells their own coolant, but there's got to be a home brewed solution (pun intended) vs. buying it from Woodmizer.
Any thoughts? If I can come up with a cheap alternative, I might be able to get some of his cast-offs
