Thread: You just got to try this.

That's a great piece of information there John,incredible on how much quicker the saw cuts,thanks for putting the link up...

Mick!!!

Beautiful. I might try it on an old blade.

Good stuff

Certainly worth a try before throwing an old blade out.

Provided you take minimal material off, would this work with the (very popular) 1/2" 3 tpi bi-metal blades from Henry Bros? I'll be using a fairly fine white alox wheel on the grinder.


Cheers

Excellent link thanks John

I did it on a 3tpi and I guess if you have the motor skill and eyesight then perhaps down to 5 tpi. It worked really well on a grey wheel that is the bog standard wheel on grinders. In have a white wheel for the turning tools that would give a better finish but as this was a first try I was not game to risk it. However seeing as it is a very light toutch to the stone I would try the white stone next time and I think that way perhaps get more sharpenings out if a blade. I am thinking that this system needs a closer look with perhaps some jig ideas. A stone could be ground to do the gullet shape and in theory a bandsaw blade could be sharpened many times. Of course setting would then be required. Something to think about.

Sometime back, I posted a thread about band saw sharpening. I simply immersed blunt blades in a trough of vinegar for two days. They come out clean and as sharp as a new blade. I have some here that have been "sharpened" 5 times. Much easier and allows you to continue with other activities. I have sharpened files this way too.

I am all for eazy. I will try it. In have heard of files being treated this way but thought it was only a one off treatment.

That's a great way of sharpening band saw blade. Cool video.

Tried it. Works. Don't think I'd do a new blade but.

There's some other methods and videos in these threads ...
Cheers,

There does look like many ways to skin this cat. I have used a chainsaw file in the past but that is no good on the bimetal blades.
I am still wondering about set as after a few sharpens it will be all gone. Has anyone had a go at that or got any info.

What size of blade do you mean?

The chainsaw file was very good on a 1" wide 1.25tpi blade, and the set wouldn't be gone for many sharpenings.

Maybe on a small width blade the teeth would disappear or lose shape before the set was a problem?

You could reset a 1/4" blade (eg) with a sawset or a hammer if you were that way inclined
Youtube has videos of commercial machines - motor driven and hand-operated.

Cheers,
Paul

Have to try this as well.

Just bought a new (old) 14" Carbatec, and even though the seller stated that it had never been used since he bought it (1998), it just doesn't seem to cut as I would have liked. Possibly an old rusty blade, or maybe my expectations are too high - first bandsaw.

Good idea but the guy labours the point a bit, vid could have been 1/4 the original length and contained the same level of info.

What's the highest TPI that anyone has done with this method?
