Big OOPS! (see below) I meant Back Catches NOT Back Checks! (I've always gotten those two mixed when talking about them...grrr) "How much wiggle room? Some wiggle room is normal to allow you to align the hammers to the strings when you glue them in. Yeah, right! A far more important alignment is the backchecks....hence the "wiggle room". The butts should be installed...then the shanks...wiggle them while the glue is setting and get them to align with the original backcheck and to have the shanks parallel with the original samples. Think in 3 dimensions when doing this job. Once all the shanks/ backchecks are in the proper alignment,....THEN the hammers are installed .....to the proper strike point and the proper "rake"."
