Never got around to putting this up. Probably a year ago I'm thinking.
Needed to switch out a tire.
One of the jackscrews was cracked clean in half. No.........you can't buy a new one........most are different sizes. Second hand ones are usually in bad shape if you can find the right size. Believe me......I tried going down this road. Spent half a day on the phone, and in front of the screen,, then decided it was just as easy to make the stupid thing.
The thread was cut to tolerance, as spec'd in Machinery's. This is a situation where I'm not going to simply cut the thread to fit an old bolt. All of the bolts remaining on the tractor were in pretty lousy shape (machinist wise). This thread must fit any commercially available nut in the size. Thread mic's are VERY nice if you do a lot of threading
.
Being as all of the nuts on the tractor are old, and slightly damaged, it's time for a new nut. Might as well go all in if you're gonna do it.
Because the screw was cut to tolerance, it could be used as a gauge for the thread in the nut. No need to make a plug gauge.
Can't turn a nut without flats.......................................................
