Threaded Rod For a Puller

[chevy.stroker]

At the flea market I found a 2 jaw puller with a missing center shaft. It is 5/8" NF thread. I'd like to make a shaft for it and have a few questions:

1. Is this material good enough or do you recommend something else (cost is a consideration): http://www.fastenal.com/web/products/detail.ex?sku=47778&ucst=t

2. I have a large USA die. (Again from the flea market for $1) Will that cut the threads OK?

I figured that I could weld a few grade 8 nuts on the top of the rod once complete.

Thanks for the help.

Thats tool steel, and going to be very difficult to machine.

I would reccomend something like this:

Why not just get a grade 8 threaded rod?

if you got a good sharp die the drill rod can be threaded It is in its annealed state. Key is a good sharp die and a lot of thread cutting oil. Not only is it oil hardening it will work harden while trying to run a die over it. I think I would go along with bluebolts suggestion. make sure you get you a swivel foot for the bottom so it dont walk and bend the rod

How long of screw? Mcmaster Carr has a 5 1/2 5/8 - 18 for $7.95 and a 13" one for $38.02. Search under forcing screws or puller screws.

For occasional use any threaded rod is good enough for that use.

If you try threading a few inches of rod with a die, likely it will be "drunken" or "wonky".

Three pullers that are shop made and have been in occasional use for some thirty years and lots of life left in them.............

I had the same problem i went to an old bolt supply place and begged them to thread a grade 8 bolt right up to the head works great but they did not like doing it it`s hard on the gear.

Just wanted to say thanks for all of the suggestions. Knowing what it was called was the key. I ordered one from McMaster for ~$8 that worked perfect.

Again thanks for the ideas and information.
