The last Acme tread rod I needed( for a cannon barrel elevation jack) I purchased from a local Bolt Supply House establishment . They had a large selection (1/4"-1 1/4") of the rods & corresponding nuts in regular stock.

From what I know Acme is stronger due to the thread form.
Truthfully it probably wouldn't make much differenence for this application.

OOPS my bad. here's joe's build video for the follower rest:

So would the commercially made follow rest buggered the threads or was it more a matter of not being able to get in that tight with the pre-made rest?

Why does it need to be ACME thread?

Acme threads don't bind up as bad as pointed threads when being advanced or loosened under pressure ...less friction than to the larger area of a thread with longer slope to a thread crown and also less thread count per inch reduces engagement per inch of object but retains strength .

David R8 - I think Fastener Force has Acme rod, don't know the cost but would be the quickest to get going if there are no shoulders required.
Sorry I missed this post Mike. I'll give them a call today.

I don’t ‘think’ so honestly. Anything will be better the 6B class thread that’s currently in the vise body. :D
