Well I finally got to use the Clark. Keep in mind I've never used a hollower. My first impression was that it was difficult, then I made some changes. At first I had the shaft that holds the cutter out too far and I had some chatter. Once I made some adjustments it really got smooth to operate. Now I need a lathe that has more torque i could cut so aggressively that I could stop the lathe. I still think I can make some more adjustments and it'll get even better. I was able to get the inside so clean that it barley will need to be sanded. My only 2 complaints are that the Allan head screws that hold the Lazar to the main shaft are on the bottom of the mount and one of the mounts had different size Allan's than the other. ( believe that was not a commonality, just a fluke) other than that this, it operates like a dream. MAN DOES IT REMOVE MATERIAL. I would give an "A-"
I would like someday to try some of the other hollowing systems on the market, just for the comparison. A tool like this can really open up many possibilities when it comes to building large pieces.
If anyone else has one I'd like your opinion on it. Any input is always welcome too.
