These pix will give u an idea of what I have in mind. The 24” Cincinnati shaper came with one tool holder that’s really for a lathe since it holds tool at wrong angle. I have 3 0f these large forged tool holders that fit the shaper lantern post perfectly but are useless for correct shaper cutting, although we’ve done some test shaping with it and a specially ground cutter. It works but finish is poor. John Morris has shared 3 photos with you! | Flickr
So I’m thinking of making the cutter slot parallel to the bottom edge of the holder. Yes wire edm would be great but we don’t have it. I’ll need a wedge for the bottom rear of the slot and a small circular wedge under the square-head cutter retaining screw but those are easy. What is best metal removal method for the wedge of forged steel I need to remove at top of the nearly square hole? One-side square file, long keyway broach, or what? I’m guessing someone’s already done this. Or just start over and make a minimalist T-shaped holder like video guy Steve Summers does? I’ve looked for original shaper toolholders for 1/2 inch cutters but can’t find. I have smaller pivot-head holders for shapers but they take 1/4 in. Cutters, I want to use 1/2 in. Or larger.
