I've built quite a few of these, Sorry to jump in late...

Hourglassing is not a big problem if you've got legs to hide it behind,
just figure a few feet extra each side.

If you use cheap limits, then Bert is right, use good limits with a fine
adjust, and you'll be in there easy, use an optical encoder/counter and
a PLC and you can adjust it from the deck.
