Hi guys and gals, newbie here and just have a question about my Model 66.

I just picked this bad boy up and replaced the belts and motor on it. When I bought it, it had a 5hp 3 phase Bauldor motor on, which is for sale by the way. I replaced it with a Lesson 3hp single phase motor. I also put 3 new belts on her, which took 10 days to get from USPS. The belts where purchased only a 100 miles away, and traveled darn near a thousand to get to me. But anyway, squirrel……………

I got everything replaced and put back together, standing back and admiring my new/old table saw and then started her up. About 5-8 seconds into the blade spinning, a high pitched noise, like a dog whistle but you could here. A very piercing pitched noise, shut her down, checked the belts, alignment, and the arbor. Everything seems to be where is should, the arbors tight, no slop in it, the blade is good and tight, and the belts seem good.

So heres the million dollar question, what the hell wrong with it?!

I'm spinning a Alamo blade designed to cut aluminum, so its a heavier, thicker blade, with a max rpm of 6k, which the motor spins at 3450, so thats all within tolerance.

Searched the forum looking for something close but not really came across anything like this problem. Any help would be greatly appreciated.:blink:

motor RPM is not the same as arbor

The different pulley sizes change the RPM from the motor to the arbor. Motor at 3450, arbor at 5000 RPM for example.

Remove the blade and try it without.. I'm betting it's fine. Try a different blade then it will be fine. Some blades "sing" and other don't. :no:

Nice saw! You will love it!

My saw sings once in awhile too but it never lasts long. I don't know why. Try simply raising or lowering the blade or try a zero clearance insert.

On second thought.....you don't want that crummy old singing saw. I'll come a take it off your hands. Ha

Good advice both about the pulley size and the blade. You remember some of the older blades that could really sing too? Piercing!

Whewwww.......I thought I was going nuts! You all have to forgive me, I'm use to worki g with metal.

The thing thing that has me puzzled is, when put on my cheap little Ace Hardware portable saw, it makes no noise, but also spins faster, does the rpms make a difference in the blades singing ability?

The pulleys are the same in size, does that mean the arbor is spinning as fast as the motor, like a 1:1 ratio.

Please bear with me, all new to this woodworking thing. Whats probably going to make all you guys nuts is that saw will never see another piece of wood. I bought it strickly to cut sheets of aluminum diamond plate and extruded shapes only. :icon_smile:

no woodcutting????

Then get the heck off of our woodcutting forum, you metal worker spy. :laughing:
Go away and listen to your singing saw blades..... :no:
Glad we could help. Yes, if the pulleys are the same size it's a 1:1 ratio. :yes:

I'm feeling the love!

Maybe I might have to give this woodworking thing a try! I already like the people!

The only problem I have with wood, is when you make a mistake, you can't just weld a piece on, sand it, and call it like it never happened! You have to go and get another piece and start all over, that darn wood grain thing!

Besides that, most metal workers don't know a damn thing about table saws! You go to where the experts are..........I am in the right place, right?

Take off all the belts and see if it still makes the noise. Then add one belt at a time until you hear the noise; that will let you pinpoint where the source is.

 

[Frosted Flakes]

So RBK, your thinking it might be a belt problem, not just a singing blade?

I will give a try tonight when I get back to the shop.:thumbsup:

 

[rbk123]

Could be either, or something else entirely. Maybe it's your middle pulley. Start with nothing hooked up and add in a piece at a time until you hear it.

You could test the blade theory first if you'd like since that's the easiest to test.

OH Yah?
We have Weldwood glue.... 'bout the same, not instant like MIG, but it'll do. BTW I weld also, I spray metal with an Airco 200 AMP MIG and run 8% Argon.
A smart woodworker always comes up with a way to cover his tracks / mistakes., sorta separates the pros from the newbies.
We just know to to fix 'em.

Most table saws are not familiar with metal workers either so it's a wash. I did put a cut off wheel in a table saw once, but I forget why.
I do metal grinding on a wood belt sander occasionally and caught the shop vac on fire once...seems the hot sparks settled in the wood dust. I empty it right away now. :yes:

Thats some thick steel to spray, especially 8% argon. I usaully use with thicker weldment a 98 argon-2% oxygen. Much hotter arc and sprays very fine.

I had the shop vac fire happen when cutting long strips of aluminum, but mine wasn't saw dust, some dust bunnies the wife sucked up and forgot to tell me. So, to say the least, its amazing how fast those shop vacs melt down when your not paying attention to them.

Whats amazed me, is that since I specialized more in aluminum, how many woodworking tools I have since acquired. Miter boxes, sliding compound miter, 2 table saws, now looking at a vertical bandsaw..............hell, all I need now is a joiner, planer, and a shaper, then you all can me Norm. The only problem would be, I wouldn't have any idea on how to use them for wood!

 

[woodnthings]

vertical bandsaw?

I have one of these and it's great!

You can saw aluminum with a woodcutting bandsaw just like wood.
You need a blade with several teeth that will span the thickness of the plate, 6TPI or so depending. I use the Roll In for steel, but for occasional cutting of aluminum, I use my wood cutting bandsaw.

You can't have too many bandsaws because that way you don't have to change blades each time you have a different operation. I hate changing blades ... on any saw. You can't have too many table saws either... just sayin' :yes:

 

[Frosted Flakes]

Thats a wild looking bandsaw, what kind is it? Whats with the lever? Is it single phase?

I was using a Dake tonight at work, that's a sweet bandsaw! It has on the fly motor adjustments for rpms, problem being, its a 3 phase saw and carries a STEEP price tag!

 

[woodnthings]

It's called a Roll In and here's the site. The lever is the feed control and it is self feeding once you start it. It rolls down a incline ramp, gravity feed to maintain pressure against the material. You can get it 1 or 3 phase, mine is single, 120V. :smile:

The good thing about working with wood, is that it doesn't get hot while you're working on it. When I took welding, after working with wood for a few decades, it took me a few times the hard way to learn that what I was working on did get hot.

I've been a welder for almost 20 years and still forget how hot the material gets and how looonnngggg it stays hot.

I will say how nice it is for the forum to be accepting of all who come to ask questions and learn. I know on some of the welding or pipeliner sites, the guys can be pretty brutal with the newbies.:sweatdrop:
