Hello all,
Does anyone see any pros or cons of changing the cross travel lead screw to something a little less random? I’ve got an Ammco 7” shaper and the cross travel leadscrew is 1/2-13. I’m not saying I WANT to do it. But it occurred to me that a 1/2-20 would be a little easier (possible) to cipher on. I don’t think they chose 13 tpi arbitrarily, but I can’t come up with a really good reason why. Probably something to do with the ratchet mechanisms diameter and tooth count. So anyhow, I’m free writing here it seems. What do you say? Any thoughts?
