Ball Screw Stock ?

Hey lynlynch could it be acme threads. The thread would have flats

No cigar. But thanks. The bottom of the thread is hemispherical and looks like it would accommodate 1/8 or so ball bearings nicely, but is not finished the same as ball screw or lead screw stock. The major diameter or peak of the thread is left rough. Thread pitch is much coarser than the lead screw you have pictured also.

Thanks again.

OK, this is hugely out of scale and not well drawn, but bears some resemblence to the rod in question. Major dia about 3/8".

You get the prize!

That looks just like it and the usage as a concrete fastener makes sense because it was installed the last time by the guy who made the concrete bases for many of the pieces. He may have had the matching nuts brazed on by someone.

Thanks to farmatt for the great pictures, but it's definitely coil threaded bar stock.

Thanks to ozzb for your contribution, too. And Holzfeller, yes it is worthy of Cadillac parts.

BruceFlorida I'll remind him about the five bucks when he gets back on the wall.

Thanks guys!

Your drawing and the ball screw nomenclature triggered my memory as my father used coil threaded rod for an anchoring system for a project to secure some Fiberglass charactures in a children's park. Sorry to hear someone knocked him down...poor guy's fallen once already. Four of those should hold it down nice and tight. Can you get a galvanized steel plate 4 X 6 inch's inside with four equally spaced holes drilled thru , lock washers and nuts on top...that is how we secured ours and there still there today. Anyway good luck Lynlynch...your heart is in a good place...wish you the best!

We have room for a plate larger than 4x6 and very likely will use this approach since it will distribute the load inside better than the present set-up.

At least now, when I go the the nut and bolt place I'll know what to ask for.

Cheers.

Looks like it might come from something like a ball & nut type steering gear, but I'm not that familiar with them, so probably wrong. But if so, the sculpture is probably worthy of Cadillac parts.

Something like this?

Just remembered that the fan speed adjustment on my dads Clipper 29D seed cleaner was the same rod as you described from memory, I think it was about the same size. you might check a used farm equipment junk yard for a replacement rod and nut.

That name rings a bell! Clipper seed cleaners - haven't seen one for maybe 50 years but I remember well spending many hours working one.

We have no farm equipment junk yards here in AZ. But, I am going to the heart of farmland next week when I go to SW Minn. There's a farm implement company (complete with junk yard) about 100 yards from my place there. Maybe I'll just walk over and take a look.

Thanks.

I now have 12 feet of coil threaded bar. I thank you. Humpty thanks you, where the stroy came from.

Cheers.
