lol...some arf still comes with dowls as control rods

It's cheaper too, plus a 24" metal rod usually arn't lone enough

You just purchase regular metal rods and just cut them and connect them to the dowls.
You can wrap threads around the rod/dowls to secure it. Just use CA or epoxy.
You can drill holes into the dowl...but you don't need to.

If you want threads for the cleves on both ends...just buy shorter rod the threads/cleves on them.
If you want cleves on one end and a hook on the oposite. Just whack a 24" rod.
