How to Tighten Jib Block Solo ?

[rhr1956]

I need to tighten the nut from inside the cabin while holding the slotted screw topside. Or maybe tighten from topside while holding wrench somehow from inside? Advice please...

I knew there was a simple answer...duh...

Snap a pair of Vise Grips on the nut horizontally with the handle of the grip up against someting to prevent the nut from spinning whilst tightening, "Usually" works every time.

I've seen vise grips used to clamp on 1 x 1 or pipe to OTHER vise grips, which were used to grab the nut. The "extended" grips would eventually hit a bulkhead or the mast, stop the turning movement, and the dogging down of the bolt could proceed solo.
