Youve got to love this metric world we live in


Perhaps i should have quoted the paxolin is approx 3.27mm thick and the holes are drilled with No 51 !!

Excellent work, most time is spent thinking through a design and checking everything’s right before committing materials.
And a lot of patience

Making a rudder tiller that doesn't distort is a problem on a Stearman due to its slope. The first pic is from the parts catalogue.

I fabricated this from two pieces go 0.5mm stainless which i formed concave,( eg see last pic ) then silver soldiered the edges to create hollow arms

I envy your patience Kevin, at least the rudder horns will be visible, seems a pity that so much of your engineering will be hidden.

Fin and rudder finally complete. Had to add a lot of reinforcement to support the revised tiller.
