Hi I have a single
hydraulic ram to a bronze quadrant on a 1 3/4 in diameter rudder
stock. Quad is secured by 4 large ss bolts into the rudder
post, which sit in 4 drilled recesses. The rudder is not balanced and is large. The forces on the poor old quad are huge, and after 2 days at anchor
the 'play' in the lashed rudder had worn the recesses and the quadrant was slipping. The post is very hard so drilling is a near impossible task!
I have thought of a few solutions, but I have had trouble finding the parts
1 grinding the tips of the ss bolts to improve seating - surely there is a harder stock bolt available, with a pin at the end?
2 grinding the stock square and machining a ss quad to fit
3 lathing a substantial round ss collar quad, and grinding key steel
recesses, and also welding onto stock
4 creating an 'over' clamp to reinforce the pressure on the quad on the stock
you get the idea!
Ideas welcome - I wouldn't wants to take the current
arrangement into heavy weather
