I am using a 8/12 3/4" blade. It has very little use. I noticed when I let the saw cut aggressively, a chunk of chips will stick to the blade. This causes it to jump when it cycles around. I can knock it off with a brush as it comes around.
I am using wax. I do have the Kool Mist I could apply to the cuts.
I was cutting a piece of aluminum, 1" thick by 4" wide.
It did cut straight, I'm not complaining about the quality of the cut.
I can slow it down or speed it up. I'm not sure what speed I am running. I don't have a guide for the pulleys, it just seems right.
Marvel 612.
Thanks

I was just cutting 1x6” aluminum on my horizontal 10-1/2 blade, WD 40 worked good

Yes, definitely use a lubricant, WD is OK, or kerosene.

All these years I have heard WD40 is worthless until I got into machining. You guys use it all the time.
I'll give it a shot. I am cutting spacers for my DRO.

That’s about all it’s good for , displacing water and cutting aluminum

There should be a "wire brush" attachment on the bandsaw that clears the blade of chips. I use the wax stick lube.

I have seen those wire brushes.
This old saw is not currently equipped.
I just bought some wd 40

You can easily equip your saw with a standard wire brush for a drill or a grinder and quick custom bracket.

Holy Schnikies!
I just chucked up the same piece of aluminum, let the blade ride the wind with WD 40.
It cut straight, smooth and fast.
Less than 45 seconds to cut this piece.
Thank you WD40. Thank you Hobby Machinist's Forum !

Did the coors light help, wd 40 also helps milling aluminum, but tapmatic is what I use when tapping alu.

Coors Light lubricates the operator. Just one before supper.

I saw somewhere on the web from an old guy who advised to use a piece of wood. I tried that and it is working very good. I just held a piece of 2x4 on the blade as it passes as a test. I was quite surprised to see the stuck alu chips falling of the blade when it passes through the wood.

2” aluminum stock, cut very fast and clean. I got the guide bearings adjusted properly.
This old Marvel 612 has been re-born.
