Buzz saw blade sharpening question

[FarmboyBill]

The bevel on a tooth that gets sharpened, can be either on the inside of the valley, or on the outside, depending on which direction the tooth is bent.
Which is right? For the bevel to be on the inside of the Valley, or on the outside?

Two part video that should answer it all for ya Bill..

You should watch the vid yourself simi. Ive watched it maybe 3 times, last year and this. It DFONT answer the question, at least so I can understand it.

Think of it like a chain saw tooth... the side that sticks out the furthest has the sharp edge of the bevel to the outside.. so if looking at the edge of the tooth from the front, and it's stuck out to the left, the closest part of the bevel with be on the left side to the outside of the tooth, and the furthest part of the bevel will be to the inside or right of the tooth edge.. The cutting edge is to the outside of the valley...

This is the same question you asked last year. Did you file the saw last year? How did it cut? If it cut good then do it the same way. Your description of the blade is very hard to decipher. If you are looking at the tooth and it is bent away from you then the bevel is toward you.

This is like that scene with Tom Sawyer getting the boys to whitewash the fence for him.

Any volunteers wanting to head out to Oklahoma and sharpen a couple of buzz saw blades?

I have one of these saws that I rescued from the woods when we bought the farm. I had to cut a four inch thick tree that had grown up through it. I wanted it as much as the farm. It was some sort of symbol to me that I can't put my finger on. I greased it, turned it through by hand, put it in the barn and covered it up where I could covet it each time I went into the barn. I am afraid that saw. I am afraid that I will never get it out of the barn and put a belt on it to see it work. I am more afraid that I will. I am afraid of that saw.

I sharpened it. From what your saying, as I understand it simi, I have it wrong. I have the bevel cutting edge on the inside of the teeth.
I will have to reswedge it.
I cut old dry wood. NO GREEN, and so its pretty hard wood. ive never been satisfied with the cut, but I accepted that as what to expect cutting dry wood.

Just remember when the blade is moving into the work, you want the thin leading edge of the tooth bevel to hit the work first, then the back edge of the bevel to clean out the cut.. Think of it like a wood chisel.. you want the pointed thin edge towards the work and the waste to slide up over the bevel..

This is just too hard for me to describe.. LOL..

Like I said.. grab your chain saw and look at the teeth on it.. You'll get the idea then.. The way the tooth on your circ blade is bent out, gets the thin cutting edge..

[FarmboyBill]

U described it fine. Thanks.

Sounds like you're suffering from an attack of common sense. Things look dangerous as all get out. I'd imagine there are a lot of former operators nicknamed "Lefty".

[simi-steading]

Nah.. buzzsaws ain't so dangerous.. check out a shingle mill some time... You almost have to put your hand right up against the blade on some of them..

Ive been using this buzz saw since around 68. Never lost anything around it. My dad and granddad used it before me. I carried wood into the house from the wood pile they made with it.

Bret; next time you're in the neighborhood give a call. I have one myself that I run with a 5hp. Economy engine. And if you need a flat belt to run it I have several of them that I could hook you up with one.

[FarmboyBill]

5 hp? . What size dia blade do you have? Mines 30in. I find my 34 Case has a faster RPM than my 48 H Farmall. I could tell the difference when sawing with the H. That didn't last ling. The Case stays belted to the saw, and the H drags them up close. The Cub hauls also, dragging limbs and snaking and wiggling between already cut limbs to get them as close to the saw as possible.

[Phil V.]

The Economy engine was made by Hercules in Evansville,IN.. They were sold by Sears & Roebuck. You could order them through the catalog or go to the store and get them. They were 1 1/2 hp. up to 14 hp. in size. The 5 hp. that I have runs at 450 rpm. It doesn't run fast but has a lot of torque. T two flywheels are about 22" in diameter. Altogether the engine and cart weigh about 1000 lbs.. I'll post a pic in the next day or two so you can see how big it actually is.

[FarmboyBill]

What I asked was how big a dia was your saw blade. BUT If you have an old one lunger, then 5hp would be plenty. Having lots of torque rather than lots of speed would, id think, throw the belt a lot. Especially on a stationary engine that cant be backed into the belt as tight as a tractor can.

[Phil V.]

Sorry about that. It's 29" in diameter. It does a 12" cut on the table. When I start buzzing wood I have everything anchored down with 1/2 " rebar drove 10" into the ground.
