Screw drive setup/layout

The only thing that I would suggest to change would be the steel furniture nut. After this summers usage and moving over 300 loads of wet dirt, I eventually wore out the nut and threads on the threaded rod.
It was a quick fix, as I just turned the rod end for end and put on a new nut. Even with liberal use of anti size, steel on steel is not a good mix.
My suggestion is to make the nut out of brass and make it the same length as your delrin slider block. The longer the nut the more the pressure is spread out along the threads.
My winter project is to make a new longer nut and I'll post some pictures on my thread.

I do agree the furniture nut is not the perfect thing to use but you did not do yours any favor by using anti seize depending on the type you were using. The silver and copper colored anti seize contain metal and are not meant to be used as a lubricant. You can get a graphite based anti seize but it can still be abrasive.

I have thought about just treading the delrin block and see how that would work.

Yup, anti seize is not typically used as a lubricant . As the name says, it prevents two combined stationary items from seizing together over a period of time and use. Also the dust and dirt that would cling to it would add to accelerated wear.

put way grease on them ( mobile XHP 222 ) It's a multipurpose grease I use that in my diffs too Threading Delrin will not last any longer then steel unless you can polish the threads on the threaded rod . an acme threaded rod or ball screw would be the best option . I just never seen a ball screw small enough for this app
