re: ZCI Interchangeable Inserts.

well glad that i inspired you ! on my old saw i had an anodized throat plate that excepted replaceable inserts like yours ducks. loved it, precision made. i believe it wwas from infinity tools also. sadly this italian saw i have now doesn't conform to anything ! so i just make mine from oak. you did a hell of a great job detailing your whole process. i wish i had the patience to read it all ! so instead i just made a bunch of solid ones for different blades and angles. nice wright ducks !
