Reilly, Good Tip....I also use brass rod 3/16" dis. Easy to slot and solder a brass plate to, have never had a problem with bending, etc. I generally use them as a core and cover with plastic, wood or just leave as is. Joe

I would prefer to use brass rod for the rudder shaft as it will be easier to cut and also to solder the rudder plate.

Thank you both for the replies I will try the junior hacksaw as I found one in my tool box fancy finding something useful in your tool box.

I make the rudder axis in stainless steel, and I make the slot, just where I need using my Dremel

I agree, easy fix, I have done loads with a junior hacksaw, then soldered the rudder blade to the shaft, usually in brass.

I've never come across one, but they're easy enough to make with a Dremel using a cutting disk...
