Elevating screw
Posted by Steve on 6/8/2008, 2:24 am
Hi Guys, I'm building a 5th scale, non-firing 1874 Gatling gun & carriage scaled from drawings and photos. I can't find any info relating to what stops the elevating screw rotating when the height adjustment wheel is turned. It's the type where the screw protrudes from the carriage with a ball on the end, and the hand wheel is close to the carriage. I can't see any sign of a key-way, or flats milled under teh ball etc. Any help greatly appreciated!
