More Rudder Prep (11/29/09)

1.5 Hours -

More rudder prep today.  I’ve finished just about everything I can until my order from onlinemetals.com arrives.

First, I had to match drill the rudder counterweight to the counterweight rib.  Then, I countersunk the weight using my deburr tool.  The weight is lead, a very soft metal, so removing material was simple.  The rib, however, had to be dimpled and I don’t have a #10 dimple set.

There are not many places where you have to use a #10 dimple die, so buying one would be a bit of a waste of money.  Many other builders have made there own, so I followed suit.  The female die was made by countersinking a piece of wood.  I then dimpled the rib using my #8 dimple die and finished off the dimple by placing a screw through the rib and wood block and tightening a nut until the screw adequately pulled the metal into place around it.  The resulting dimple wasn’t perfect, but it will suffice.

A wood block was used to make a #10 dimple die.

Using my homemade #10 dimple die on the counterweight rib.

The counterweight rib is dimpled while the counterweight is countersunk.

Finally, I prepped and primed all of the rudder pieces except for the trailing edge wedge.  I still need to countersink both sides of all the holes on the wedge, so priming it will have to wait for another day.

More priming...
