 I adjusted the clutch on my Covington. The blade stopped on the second cut of silicon carbide. I realized that I needed to tighten the set screw. I cut one slice of my small Blue Biggs and on the second cut the blade started pushing the carriage away. I cut off a big heel piece on the Owyhee and on the first slab the blade drifted again so I manually started the cut and subsequent ones. That solved the problem until the fourth cut where the set screw came loose again. I was planning to dress the blade after that cut. I completed the cut and got three nice slabs. I'll glue the heel to a board and make some smaller slabs. I'm having to relearn some things and I have some questions. 1. Should I get some Blue Loctite for the set screw, 2. There is another set screw on a ring on the cross feed. Should I setting that ring to stop the drift. I never did that before. 3. Is starting the cut manually a bad idea? |

There are set screws with a plastic insert in the threads that hold well in a vibrating environment, you might stop at Ace Hdw. and pick one up.

I called Covington and the said starting the cut by pushing the blade into it to score was correct. I cut a heel and one slab that ended up 1/2 inch (still learning). Looking at the rock, there wasn't much but that's why I ask someone who knows more to pick.  |

I finished cutting the Blue Owyhee. I have a couple more slices soaking off the board. I'm getting the thickness better and I bought some calipers to help with that and cab descriptions. I'm holding off splitting the Blue Biggs so I can improve my cutting. The saw is performing great. I'm dressing my blade now and then will start taking slices of the big Morgan Hill piece. I have some fractures to work around and will be spending some time on the trim saw before I can start designing.  |
