i have had more trouble lately with these saws then its worth. First one would stall and not cut. I think i got that fixed do to the help i recieved here. But now, it won't cut . It runs and runs and doesn't cut anything. :help: I decided to let it sit awhile and use the other one and guess what? ? Now that one has started to do the samething....OMG i'm going crazy. I figured its the blades so i changed them, and hmmmmmmm thats not working. Anyone have some ideas?? ty ralph and mary ann PS Where do you all buy your blades? I have been getting them from danial, but i think they should last longer then 2-3 months. I do cut all day long, everyday..... but still i can't afford new blades that often. ty

I run into some material once that would instantly pull the diamond out of the rim. I destroyed two blades before I figured it out. Take a magnifying glass and look at the rim. If you see little voids where the diamond would normally be, then you may want to reconsider what your cutting.

Three months is about what I hear for Covington's Gold blades that are made in China as are Lopacki's. Two to three months full time use is probably about it. You should be using slowest feed speed and cutting with oil. You should ask Lopacki as he is the supplier but I think you are getting normal use for a commercial application on a Chinese blade.

Man that sucks! I'd say you at least got your 25$ worth from the one saw, eh? The front left pulley on my HP 18" is shot. I can tighten down the set screw but the (race?) inside of the pulley's wore out so it slops to one side or the other, eventually loosening the screw and traveling one way or the other. Any idea where I could get a new pulley for an old dinosaur? ;D

Screw feed system on the 18"ers? I bet your threads have worn out on the feed systems, too much sludge in the oil acts like sand paper and wears down the threads. I have that problem sometimes, it is worse in the winter for me because the oil gets thicker and carries more sludge.
Beef, you can order new pulleys from almost any ace hardware store, just need pulley size and shaft size.

I have the same problems with my 18", 12" & 10" saws before. Once it was a pulley that lost its set screw so the blade would just not turn, the pulley spun on the shaft. The hard one to figure was the spring tensioner that held the slpit nut on the threaded rod lost its pull and it would just sit against the blade. You might have a load of gunk built up on the threads of the drive rod also-try a can of spray degreaser the length of the rod. Hope one of the easy fixes works!!

If it started working again, I would bet it is either the spring on the feed nut, or it could be a spring on the drive motor, depending on if you have a belt drive motor or if your feed is gear driven. Something intermittent like that should be either spring tension, or belt slippage.
Good luck in finding it............Tony
