Blades Cont'

[Shane Watson]

Ok, so I have my new blades. I decided as they were cheap enough to get a 1inch and a 3/8inch. Both 3tpi skip tooth.

I fitted the 1inch first to see how that bugger performed. In the words of a golfer "If you get the big dog out, MAKE THE BUGGER BARK" Talking about driving irons obviously......

Anyway back to it.....

So with the inch blade fitted I ripped some 200sq laminated s/o. 24 cuts latter the damn thing is as blunt as a butter knife.... Is this typical life expectancy from a bandsaw blade? Or am I expecting too much? http://ubb.ubeaut.com.au/ubb/confused.gif

I havnt fitted the 3/8 blade yet. But I figure it won't last much longer on these bigger cuts.

Is it common to get bandsaw blades resharpened? Or is it more common just to toss em and buy new blades, as they really arn't that expensive.

Your thoughts???

Cheers.....

Spose I should mention that the cuts were approx 2 foot long. http://ubb.ubeaut.com.au/ubb/wink.gif

Hi Shane, As these two blades were cheap you may have purchased a lower quality blade(s)meaning that that the material they were made from is of a lower standard required to fulfil the tasks you have set out for them.

As there is different materials from which bandsaw blades are produced some inquiring of materials for purposes whether production or low key is required.

Blades are produced with carbon or high speed steel or an alloy,tungsten, and stellite getting progressively costlier as the refined process requires more input.

Any Sawdoctor worth his salt will steer you in the right direction but be prepared to pay good money for blades that will do the job for you.
If you have access to a good sawdoctor...get friendly with him and he should steer you right.

Stoppers, I am cutting Silky-oak ( 200mmsq x 600mmlong ). Its not that hard and is well over the 100yr old mark. The tablesaw cuts it like butter. The glue I used to Laminate it was AV203 a urea formeldahyde glue. Great Stuff, and while it does cure rather hard, After carful machining theres not much of a glue line that it had to go through. Wouldn't be as kind as a PVA to the blade though, I imagine...

Johnno, I tend to agree that maybe they are a cheap quality, and I might get my next blades from 's source.

Thanks for your input guys!

Cheers.
