What is the most impressive, is how quiet the motor is. There's not a lot of vibration in it. I personally think that they should be using finer thread bolts on some of the outher adjustments, and nuts instead, whil using the machine chain Stop, it will slowly move. I am rebuilding the chain stop, and adding some Wing nuts along with the plastic Wheels. I purchased a diamond sharpening wheel after my second composite wheel blew up and the Machine. I did inspect these wheels and make sure that they were good before I put them on. What's the first wheel blew up I started getting a lot of chatter, this is because the chain sits too far back behind center of the wheel so I put some extra shims a longer bolts and where the chain real is to correct this problem. The chain stop was constantly hooking my chains I'm getting caught in the wrong direction, overall I think it is a great machine. The chain Rail and stop system does need some serious attention. Whenever I sit down in front of a lathe machine Mill doesn't really matter what at that point I am going for precision. For me the chain rail stop system on this machine was not adequate. the chain lock system is very poor as well always releasing my chain. Which is why I had to composite Wheels blow up. Still love the machine though. Works great and if I wasn't so anal about being exact it would be perfect.
