Install properly bored hammers. > > Newton Thanks guys and gals... but I would like to point out that if I go for a shorter bore.. then I exasperate the problem with drop screws being already to high... Those of you who mention glide bolts... I'll let you know about them tommorrow... I was wondering about the distance between the hammershank flange screw and the flange centerpins as well...(remember shanks are not origionals)... .but havent had time to sit down think this one through yet... I also have thought about the drop screw itself.. there are different lengths from the center pin for these as well.... What muffs me with this is that the letoff button is in an ok position... can easily regulate higher.... but the drop screws are way high already... even if they werent draging on the block I would have trouble getting them much higher I think. Thanks for all your thoughts so far...keep em comming..:) Cheers !
