Title: Brass rudder swg advice please
Post by: trelawney on November 22, 2018, 02:03:57 pm

Model launch 30 inches long with a rudder approx 45mm by 45mm.


No thickness given on drawing


I have some 18swg brass sheet which is  1.219mm, but it looks a tad thick to me.


Would appreciate members advice as to which gauge would be suitable


Thank you

Use what you have.
The extra thickness
will give a bit of rigidity.

Especially if your 'ground' the boat!

the other advice i would give is if you are slitting the rudder post to insert the brass, make the rudder the same thickness as the saw kerf
