Week 66 This week we get the rudder
The bits we received
And what we did with them
Tidy up the parts with a file and glue them as per the instructions. Make sure they're straight and square. Now let the glue set completely.
Rather than start with the brass rod at the front, I started at the back. No particular reason, it just seemed slightly easier. The brass rod needed bending a little to get a perfect fit. The brass seemed quite hard and springy. To make it softer, heat it up with a blow lamp until it just starts to glow a dull red, and allow it to cool naturally. No need to quench it in water. Be careful not to burn yourself. It will now bend very easily. I glued the brass to the bottom of the upright, and to the back of the two ribs and allowed it to set. The photo above shows how I held it in place with masking tape.
Here it is with the front section glued in place.
Finally here is the completed rudder with the control horn glued in place.
Hot tip of the week
Both brass and copper can be softened with heat. You can use either a blow lamp or a gas ring. Heat it up till it glows dull red and allow to cool naturally. No need to quench it in water as rod this thin cools quickly. Don't heat it any hotter than dull red as it is quite easy to melt the rod. Be careful not to burn yourself.
