I was looking at the hegner clamps, and I'm not sure how they would fit the AMT. Did your saw have a slot at the end of the arms that the blade went through after it was tensioned? Mine doesn't and I don't have any way to hold the clamp on the saw. The original had a thin metal strap that it snapped in and out of. I can send pictures if it would help, since I'm not really describing it too well.
Thank you for taking the time to respond, I appreciate the help.
