Default Acme thread?

I need to have an adapter made to screw on the male thread on a telescopic pole. It's the same thread that's found in the end of paint rollers or mop handles. Does anyone know if there is a tap available to cut this thread? Size designation? By my measurements it looks like diameter of the male thread is approx. .704 to .72" with 5 threads to the inch but I haven't found anything to match this in several tool catalogs that I've checked.

Thanks for any info in this regard.

Bill

MSC has a large variety of ACME thread taps and dies.

Rick,

Thanks for posting. That was the information I was looking for. None of the Canadian tool catalogs that I checked had a 3/4" X 5 Acme tap listed. I see by the price of them they probably thought they wouldn't sell any!

Now I'll have to decide whether to spring for a tap or go with having a coupling nut turned down to fit a bulb changer.

Maybe cut off a paint roller handle and secure your bulb changer to the steel rod portion of the roller handle that you choose not to cut off..

You can weld or braze to it but the easiest is to thread the steel rod with whatever common thread fits and go from there.

I mount numerous items this way. Makes a great extendable handle for a horshoe magnet, for example.

Perhaps a bulb changer too.

Kid,

Thanks for the aditional suggestions. I'm leaning towards the coupling nut and a slotted broom handle adapter that I have with the male thread. The handle of the bulb changer should fit nicely inside the adapter and can clamp it with an attached screw. Just waiting for availability and price from a possible Canadian source for the coupling nut.

I note there are 5' extendable poles made for the bulb changer but would need 4 of them to reach lights in a skating arena. At about $50 for each 5' pole, decided to go with a telescopic pole with the Acme thread for about $40.

Elden,

Duct tape was going to be my backup plan! Regular or Gorilla?

Depends on how hard you're gonna use the pole and how good a helmet you wear.

It's your executive decision.

Elden,

Wasn't planning on using the pole & bulb changer myself so guess doesn't really matter!

Default Re: Acme thread?

I am looking for an economical way to attach a standard acme 3/4" x 5 handle to a steel plate. I have some magnetic pick up tools that have an adapter from female acme thread to a stud that is welded to the metal disc that holds the magnet. The closest thing I have found after several hours of searching the net is a 3/4" x 5 nut from McMaster Carr. I do not think the threads are deep enough to hold a handle securely.

The adapter used on the pick up tool should be an inexpensive piece, if I just knew where to purchase it.

Any suggestions? Thanks

Get a coupling nut. They're about 2" long.

If this is a one time thing, you could simply saw and file the threads into a new handle.
I have seen Roy Underhill do it. He cuts a triangle shape out of paper, wraps it around the stock and marks each wrap. Then files the threads.

This isn't quite what I remember seeing, years ago, but you will get the idea.
Here, he is actually making a steel tap using that method.

That would likely work fine, but at close to $30, not cost effective.
