A Thread Thread

[farmersamm]

I needed to make an Acme thingy to use in a build of another thingy.

I don't have a jig for attaching round stock "ears" to bolts or other round things.

So...................................

I need the Acme threaded rod to be hinged.

To make sure the axle/pin was true, I welded it to a piece of flat stock.

Then used an annular cutter to cut a hole through the round stock, and flat stock, in a single pass. This left me with an absolutely true axle.

Then I welded a piece of extruded tubing in the hole to accept the threaded bar.

This is one piece completed. It will be the imobile part of the assembly

There is another to do on the next post

This next assembly is the nut assembly which will travel along the threaded rod as the rod is turned.

It's slightly different, but the same principle.

The axle was welded to the piece of flat stock

Then a section of the axle was cut out

Then a hole big enough to allow the threaded rod to pass freely was cut through the stock

And the nut welded on. The axles, although not touching the nut, will stay true. Welding in the gap would cause the assembly to bow due to the shrinkage

Weird, but it works

I suppose this has something to do w/ the "What the----????" thread. I take it you're not ready to enlighten us about that one.

H,mmm I'm impressed, just not sure exactly why..............

ha, I was just thinking when I seen the square frame flopped over so far on the lift thingy that your going to need a screw jack or something to adjust & hold the angle

Decent source for Acme threaded products?

I needed one to fix my (chineese) Bench Vise. I got the nut thru Mcmaster Carr. They were the only ones that i found that had M20 x 4.

Samm, picture 4 shows nut welded, picture 5 nut not welded. Is there 2 of these or a change in plans? Bob

[rhunt]

I see there are 2. Bob

When you go fishing, you use the right bait. I'm hooked, now tell us what it's for!

Got to be something with a heavier load since you used acme thread. You're pulling something together with the pins I assume. Probably not pushing since that's a fairly long rod compared to it's thickness.

Very interesting.
