Fair enough Tim I guess they would have to be cheaper than legacy’s ones well if they’re going to be a good price you can put me down for a couple. Remember for members ordering on some mill models the split nut can be a different shape

I just ordered one from Cindy, and will be here sometime this upcoming week. I responded the Forum as others where interested in getting some made. I have a avid young friend that has CNC as well as works for a machine shop and offered to dig into it. Kind Regards, Timothy J.

But aren’t they still available from legacy?. also if you keep a good supply of dyna-glide on your lead screw and split nut and also on the rails and make sure your saddle moves freely and easily along the rails at all times will increase split nut life as well.

Do an Internet/BING search for this - you'll be amazed. I find that the plastic Folgers and Maxwell House coffee canisters are labeled #2 - as are most milk jugs. The two coffee brands yield red and blue plastic respectively. My thought is that you embed a matching Acme rod into the mold you melt the #2 plastic in. Once cooled, you should be able to "unscrew" the rod from the plastic billet. You then cut/machine the billet to the exterior measurements you need and then split it down the center line. "Machining" can be done with your router, bandsaw, etc. Does anyone have an idea of how well the #2 plastic (HDPE) will hold up? Even if it wears down after 6 months of use - you will be able to reuse that worn out piece, with some added #2 plastic, and melt/mold a new piece. If your mold & billet is long enough, you can produce a year's-worth in one mold. If anyone tries this - or something similar, please share pictures and results.
