Sabre and Star,
Here's the way I was taught to adjust the covington feed speed. make sure your oil that's being thrown is not spraying your room (looks like the design has that covered), then with no rock or anything in the vice, move the vice all the way forward, away from the feed motor. With the unit running, grab ahold of the threaded rod with both hands. Squeeze as tight as you can, and if you can stop the rod from moving without too much effort, the adjusting nut needs to be tightened a smidge. (should be clockwise). If you cannot stop the rod, loosen the nut a smidge till you can (counter clockwise). Now that you know what to do, slowly adjust the nut till you can just barely stop the rod. Put a rock in the vise and see if it cuts without disengaging. If it still does, tighten a smidge at a time till it doesn't. If you can't achieve that without the vise sled climbing up the saw blade, you need to call Covington and talk to Dan. He may shuffle you off to Steve, but that's OK, Steve is the master.... Or, just ask for Steve! and that is the way to adjust the "clutch" on almost all covingtons. It's how I adjusted the one at the senior center where I used to help out, and once I adjusted it this way, for the next year and a half, I never needed to adjust it again, and it cut thru agates, petrified woods, alabaster, jaspers, etc... soft or hard it didn't care, the speed was perfect. I understand they're having trouble now, but I'll bet it's because the folks now taking care of the equipment simply don't have the knowledge to do it properly and messed with all the settings with they foolishly put in a concrete coring blade and proceeded to destroy a perfectly good motor!!! I offered to fix it, but they said they'd figure it out. Go figure!
- I'm looking at the pic of the saw, and see where the paint is not worn evenly. Is your sled loose? Could that be the reason it stops cutting? What does the other side of the blade look like?
More....
- You also said you have clay bricks.... You need to use a fire hardened brick to dress your blade.....
- Feed system is what you call an alligator clip.... Covington still makes their saws that way, so buying a new clip would be easy if you find that it just isn't holding on like it should. They do get old and weak like the rest of us... <GRIN>. But doubtful it's the clip.
- Also, check your threaded rod carefully.... where is "disengages". Is the thread good or worn? If worn or has developed a bare spot, nothing you do short of replacing the threaded rod will fix it.
Hope all this helps!
