Cutting aluminum

A buddy of mine who's in the logging business once told me you put the chain on backwards to cut metal similar to the way its done with a circular saw. THIS IS JUST HEARSAY so don't go doing it unless you can find out more I'm just bringing it up in case anyone has knowledge of this. So don't hold me responsible for lost appendages puncture wounds etc

Thanks for all the advice guys. I'm cutting 40mm bullet casings. Been at it for the past month and these suckers are TOUGH!!!. I've gotten a chop saw used a diamond tipped blade with it. The aluminum would melt to the blade, so I sent the blade back. Next the chop saw when out. I upgraded to a vertical band saw which is better but with the set up I have now. There is movement on the material when I cut it so now I've gone through 3 blades. 2 came from the guy a bought the bandsaw from and the last one I just bought two days ago. All the blades are Lenox and they are good blades I believe it's the vibrations towards the end of the cut that are causing the breakage. I'll upload the picture of my set up. If you have any suggestions plz let me know about stopping the vibrations or a better holder for the cartridges. Thanks
