I could see a "wave" pattern wheel(perhaps made from aluminum, cut on a laser or water jet), approximately 1/4' thick, that easily bolts to the flange on the bronze bearing... perhaps even a series of wheels bolted together, much like you see on a rose engine lathe... but one at a time can work, as well, as a start... a chain sprocket bolted to each end of the splined shaft(each end, so the rotational load is evenly applied to the splined shaft, thus eliminating any rotational twisting or flexing, in the shaft or the Legacy lead screw)… matching chain sprockets on each end of the Legacy lead screw... necessary bracketry to hold this new, splined shaft above and away from the legacy lead screw, and allowing the proper clearance needed for the pattern wheels... necessary chain to link the sprockets together, with tensioners so there is hopefully little to no backlash... so, we now have rotational power, transferred to a "carriage" of wheels that would be locked into the Legacy router carriage, and thus moving left and right as the Legacy carriage moves left and right... NOW THAT WASN'T SO DIFFICULT, NOW WAS IT!... LOL!... I see the McMaster-Carr company declaring a profit should this mod ever be completed!(bearings, shaft collars to hold the bearings, brackets, etc., etc.)… well, that's it for now... hopefully anyone who has an interest in the project will chime in and offer any comments or suggestions, before I spend what little is left of my kids inheritance!, on yet another Legacy mod... hope I have some red spray paint left over! -- You received this message because you are subscribed to a topic in the Google Groups "Legacy Ornamental Mills" group.
