This is on my plate-
Replace emergency tiller arm on a fifty footer.
So big boat and it sees ocean service so the gear has to work under high loads and tough conditions.
What is there is a simple 'T' fabricated from plain steel with a round post bottom which inserts into rudder head.
What is being specified is redoing in aluminum.
Hold on a sec and I will get photos posted but I have to come up with a robust way to use welded up aluminum for this part.
Old tiller:
Critical bit:
The solid at lower end is 1-7/8” diameter and the slot cutout is 1/2”.
I am not liking that solid out of alloy and I’m really not liking welding up the vertical to it and this is not mentioning the problem of welding up the T arms..
Tell them to jump I can’t make it strong enough out of alloy or…?
I suppose I could bring the solid up further and drop a tube over it and filet weld the bottom of tube to solid- that at least would keep working the tiller from loading the weld except in rotation.
