Absolutely, plastic nuts settle in very well after enough heat cycles as they re-form around the screw. :)

[quote=ger21;1117138]75-100ipm is about the max you'll see from 1/2-10 single start.
I get between 150-195ipm with 1/2-8 2 start, and a lot of people get 300-400ipm with 1/2-10 5 start.[/quote]
I'd just be happy to get 80ipm without the nut binding up and squalling. I am on a very ridgid budget so this was the best I could afford. Thanks for the ratings for the various screws, it will make a good reference once money becomes available.
Thanks,
John

well, I've run them quite a bit and here is where I'm at, so far silicon does the best to shut it up but only lasts about 15-20 minutes, each day I have to spray the screw down at the beginning and again every 20 minutes(wife suggested I just spritz it once in a while when its running) personally its driving me nutts, I'm now considering cutting it down one side as a relief and see what happens.

ps, if I dont continue to spray it it gets worse and worse until I cant move it at even 10ipm without it suddering/loosing steps and so on
If you have a Dremel, cut a slot in the threads near the end of the screw and run the nut over it a few times. It will act like a tap and loosen it up. Just don't make it too loose.

If it's really tight, you may gain a little more speed if you can get it looser. Personally, I doubt it will really loosen up much on it's own unless you run it a lot, for quite a long time. Especially since you're lubricating it, as the job of the lubricant is to reduce wear.

i got real close to doing that today, I pulled apart the 36" screw and nut and just for the heck of it, I tried swapping the nuts between the z and the y and voila a dab of lithium grease and its running at 100ipm without any noise at all, ran it for a couple hours and nothing so put the z back together and ran it and no noise, the noise didnt follow the nut....
