Well, I picked mine up last night, but it was too late to cut anything. So I just set it up and compound-mitered (45/45) some 1.75" galvanized sq tube:
First cut:
Not so great. The blade wandered all over the place. I stopped half way through when I saw what a mess I was making. The big gouge on the right is nearly a blade width. The saw isn't very smooth at the top of the rotation, so I probably jammed the blade into the work piece on the first cut.
Second cut, better, but not great as well:
I was more careful to keep the saw steady, but there are some small gouges 1/16" or less. The saw seems to eat a lot with each tooth, so the saw marks are very coarse, even if you take it slow. A straight mitre cut might be cleaner, as the compound puts some unusual loads on the saw.
The saw does throw big, yet cold chips. I did not see any sparks, but I won't be cutting with it again until I find my full face shield. The work piece was only a bit warm after the cut, and I was able to handle the cut end with bare hands as soon as the blade stopped spinning. There was also some burr on the trailing edge of the cut that flaked off with a gloved hand.
Over all, not that impressed with the saw; I will be keeping it however, as it's my only means for cutting metal, and its adequate for my needs. But I certainly won't be throwing out my 12" wood cutting Delta.
Cheers
Mike
