HDPE is a high density polyethylene product that comes in various sheet sizes as well as blocks and rounds. I don't know about self healing but is easy to machine and offers very little friction. I think another good alternative would be phenolic. Also comes in various sizes including round stock.

Has anyone ever made lead screw blocks out of wood? If so - what were the results? I know they made "bearings" for ships<https://en.wikipedia.org/wiki/Lignum_vitae> out of Lignum Vitae - so I'll assume one of The Group members has used wood for a screw block. I'm sure the type & quality of the species you choose will have a "bearing" ([cid:174eb9d90234cff311]) on how it performs. Just a thought. Tim - let us know how your "soon to be fabricated" Lignum Vitae screw blocks turn out. Get Happy!

I also have a set of Chinese tap and dies that work fine. remember the alternative for a 5/8 x 4 acme tap Is custom made at around $300 to me it is worth trying. that’s why I bought one I will tap a piece of Delrin when I get the chance and see but I’m sure it will work ok.

Well I found this a few weeks back and bought one it arrived today Seems to fit the Delrin nut perfectly. This could be extremely handy if you can’t buy any replacement leadscrew nuts. https://www.ebay.com/itm/1pc-ACME-5-8-4-HSS-Right-Hand-ACME-Thread-tap/254618553544?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 the listing is for 2 but I have seen it sell out and restock twice since I bought mine so every one should be ok to get one. I wanted the make sure it was the right thread before I let you all know about it. Bill -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
