I am new to the forum and to the idea of knife making. Not sure if I am in the right forum to ask this question. Correct me if I'm not. Just got the plans for making a NWGS and have been reading over them. Just wondering when making the tracking block brackets if using 1 3/4" angle iron would work instead of bending flat stock or cutting a tube? Is there a reason it is not an option listed here? Thanks
