I use staples from a paper stapler, not the big thick industrial type, no problems. they bend easily and seem to be the exact size, many grabirons are too thick.
GMCRail,
Thanks for posting your info. I’m currently bending brass .012 wire for a passenger car and I find it challenging to get the same exact results each time for a specific measurement using needle nose pliers.
I thought about building a jig, but if there is a tool that is already available and makes the job a hassle free snap, then I’m interested.
Are there other versions of this Micromark tool?
I agree with some of the respondents that it is easier to buy them from Walther’s (A-Line, Tichy, etc.) BLMA has a nice jig and if you google HO grab irons you (might) get some nice case studies of how to form grabs with serrated pliers.
