Guys, you'll love this one!
Several years back, maybe seven or eight, we had one of our customers GIVE us an ingot of 6061 aluminum. The only problem was that it was about 5 feet long X 25" X 20". Our band saw (Hyd Mech S20) could only accept about 18" X 13". Of course, the first thing we had to do was drill and tap a 5/8-11 hole in the middle for and eyebolt to move it around easier.
The only way we would be able to get it in our saw was to have it cut along it's length down the middle. So, we called some of the other shops around to see if anyone had a bigger capability saw, and all we got was a few laughs and "good lucks".
The only other thing to try was my Husky 394. We filed the chain edges to have a little less rake angle to increase edge durability and gave it a try. After a few seconds we noticed a little smoke from the quick heat buildup and got out the water hose. As long as we had water running, it cut like a dream. NEVER had to resharpen the chain, unbelievably. I remember it took about half the afternoon to get through the five foot length, but it did it.
Oh, and it threw chips up to about 50 feet.
We still use that aluminum to make fixtures, soft jaws for the vises, etc.
Now THAT is saw abuse. I still use to this day.
