Denny, if you check the first couple of sticky threads in this link they show frame fabrication as well as adjusters. For whatever reason, most don't use an Acme thread on the adjuster on fabricated wheeling machines, they will use fine threaded all thread. My cast wheel uses an Acme thread and does fine with it.
