Well, my last job I worked with aluminum a lot. a band saw that is running slow say 800rpm will last a long time cutting aluminum and it doesn't have to be carbide but it makes a hell of a noise.

the other option that I recommend to dean is lubing the blade with wax. a candle stick for example although they make better wax for this purpose. also what kills the blade is the aluminum galling which is cause by heat. take a break and keep it lubed up.

Thanks a million for the pics.


cisco that piston looks shot you might as well send the whole saw to me so I can cut it in half for you.;)

Keeping the saw blade wet with WD-40 when cutting aluminum
helps keep down on the galling or loading up, when using a file on aluminum
or any other non-porous metal, use a piece of soap stone on the file,
will help from the file loading up.

The other problem with cutting aluminum is that as soon as you cut it, it instantly oxidizes on the surface of the freshly-cut aluminum...think aluminum oxide...which is what they make sandpaper out of!

Nice pic ultra. Any idea what caused the crack?

Which one of your saws was that off of? Never seen a crack quite like that before, and I've seen some real messed up saws.....

Come to think of it, were the cylinder bolts tight? I've seen a few stihls that vibrated loose and sucked air through the base, but it always scored the exh side too......

Dayummmmmmmmmmmmmmmm that cylinder looked like it fell apart or got hit with a hammer, dayummmmmmmmm


It was cracked.. When I cut it is when it fell apart.. Looks like the intake side cylinder hold down bolts were to short. Just glad its going back together with the rite ones..

Lake, Nice pics of some nice cuts.
What was wrong with the 064 jug that you cut it up?

I didn't like the owner... :laugh:


It has a couple of fins broken of on the other side... Not much wrong with any of the cyinders that a hone wouldn't fix, but... I was having way too much fun with the bandsaw!

Dang, your going to make some people cry with your fun :)

With my untrained eye it looked good to me.

If some of those other jugs will clean up, then I have a good
066 jug, or do I? Do I need to mic it to know for sure, and if so
where at and, what should it mic out at?
