If anybody is willing to share dimensions on this tool, I'm a machinist by trade, I'm sure I could make a few sets for the guys needing them.

Here is what you will need to build the version I was making.

12" of 3/4"ACME all thread with Nut

10" black iron pipe 1" diameter with a 1" to 3/4" reducer

Tap each end with  M12 x 1.25, 1.25 inches deep.

 

 

Merry Christmas everyone, and have a Happy New Year.

Depends on how many guys need them.  I can set my machines up to turn them out pretty quick, but not wanting to do the setup work to make 1 of them.  Price will be very fair. parts+ a little labor  Not wanting to make money on these, just to cover time and expenses.

I made my own puller today from john's shopping list. I drilled out one end but I still need to tap it, I didn't have the right size in my set. Does any one know why john said to drill and tap both ends? The only reason I can come up with why you would do that is if the threads maybe got messed up on one end???

 

I was forced to buy 6' of the threaded rod so if this thing ends up working I can make 5 more if people want to buy them from me. I haven't priced it per tool yet but I would assume I could sell them for the same price John was @ $60 Shipped.

 

I'll keep you guys posted.

Drill and tap both ends in the event you strip the threads out you only need to change ends on the puller.

 

The 3/4 reducer goes towards the pin.

Thats what I was thinking. Do the threads on these fail eaisly?

 

Okay wasn't sure, I probly would have found out when I tryed to use it the wrong way.

If the pin is really stuck and there is not enough heat applied, yes they can strip.

Well after 4 attempts at drilling a hole 100% perfectly straight and center on my drill press, I have given up. With the 3/4" ACME rod there is just absolutely no room for error. the hole drilled fine but when I go to thread it it just makes holes in the bottom of the threads. I have decided to go with a some bigger ACME thread instead 7/8" or 1". Should solve my problem, guess I'll just use the rest of this rod on another project. :/

 

On a side note what thread pitch are the pins normally anyway? Because for some reason mine are 12-1.75 instead of the 12-1.25 like you posted above.

Yea. I think im gonna go with a slightly larger rod, and use a freinds lathe. If it was and SAE thread that didn't go as deep I wouldn't be concerned, but with this ACME its so thin by the time you drill a 27/64 hole in it.

 

As for the threads, I find that extreamly odd because its definantly 1.75 and the thread are not messed up. Just makes me concerned that someone put the wrong stuff in there at some point. I guess it doesnt matter Im replacing them anyway.

 

Thanks for the help John!
