Well....I got to use my Comb Unit for about a total of 16 or so hours. (Remember how quiet I said it was on the day I started it?)
I ran out of stuff to cut, and didn't want to grind without a drip water supply so I left the unit sit. I had to wait for about a week or so till Rob got back in town to give me a hand setting up the water supply. (I just managed to have it leak everywhere! LOL!)
Yesterday, water supply in place...it started making a terrible racket and the noise kept getting louder! I re-read my directions and knew I didn't put the belt on too tight. (I could easily squeeze the belt... it had plenty of play in it.)
To make a long story short...I talked to Lortone directly. They think it might have a bad bearing in it. When we pulled it apart, to remove the bearing, we found the arbor and bearing was damaged...so the entire arbor with parts is being federal expressed to Lortone today.
When it rains...it pours! The bearing nearest the blade was where the noise was coming from....anyone have an issue like this before?

What additive did you use on your water supply for the saw? I used Cool Tool, and it seperated and the pieces clogged the bearings. Shoot some WD40 on the bearings, and run it a bit. I use plain water now for the saw. The saw must be full or the bearing is not lubricated. I was looking into using 5W20 motor oil for that issue.

Ahh thanks for the info all! I use Lubri-Kool from Kingsley North for the tile saw. Just water for the grinding wheel and belt sander thingee. The oil did get pretty "muddy" and thicker on the 2nd day I did some cutting. I ended up changing out the fluid sometime last week. The bearing is near the belt and not exposed to the oil tank. (This is on thethe LU6X Lortone Comb. Unit) I did notice the Lubri-Kool was all over the bearing area. When I changed out the oil, I left things alone for several days. When I got the water supply installed, and used the unit for a couple of hours, I noticed the noise then and saw black goo coming out of the bearing area near the motor's belt. So, evidently, the Lubri-Kool did work it's way into the bearing area for sure!

Doc, I've been trying to find a lubricant that I can buy locally for the saw. Everything pretty much is a concentrate that I have to mix with water. I'm going to be talking to Lortone this week and will find out what other options I have for lubricants. The cost is a major issue for the tile saw. $20+ per gallon including shipping is a bit steep. Considering I use about 1/3 of a gallon per refill. The oil in there now is ok...but that's because I only cut with it for about an hour. If I pull an 8 hr stint of cutting...I betcha the tank will need to be refreshed again. I have to say as far as personal comfort, I really like the oil over the water. When I was grinding and shaping, my fingers were turning into prunes...and water seems much "colder". I can have my hands in oil all day and not be the least bit uncomfortable. Only thing...I DO need a bath after cutting! *grins*

He's working his fingers to the bone....
I'll check with him. Baby Oil sounds interesting!
Lortone should have the arbor this afternoon. Will have to wait till tomorrow to call them. If I don't hear from them first.
I tend to think the arbor needs a better gasket between the oil tank and the bearing unit. When cutting, the oil and grit drops right on the arbor. Then it travels the length of the arbor into the area with the bearing. Surely a rubber gasket (not plastic) Could possibly stop the introduction of oil to that sensitive area. (It's hell being a designer....I'm always looking for ways to improve things)

Here is a link for Rough & Tumble. About 3/4 of the way down in the center section is the coolant section. I know someone who uses this stuff. They have been in the hobby for a long time & tried about everything once. This is what he uses. www.roughandtumble.com/supplies/

LUBE COOL 4800 After at least 100 failed trials, we found the perfect water soluable coolant. Excellant lubricating properties, and rust inhibitors, plus added skin conditioners. Lube Cool 4800 is the most advanced 100% synthetic coolant on the market today. Does not contain any nitrosamines, phenols, nitrates, sulphur, chlorine, phosphates, or oil. Lube Cool 4800 is 100% biodegradable. Successful tests were made on all sizes of blades up to 24". The real excitement for us was how well it worked with our Pro-Slicer Diamond Blades. After all these years, we found it!! You'll be pleased with the results. For most sawing, mix 10 to 1 with water, up to 20 to 1 for grinding.
Tellfamily, is this what you're talking about?
