Got a little more work done yesterday and this morning. I added a bit of reflex to the tips, yesterday...
This is the end result from yesterday. You can see the small wedge I added to the right side to bring the tip into alignment.
...and this morning. I used a wood clamp with "C" clamp and Stilson wrenches to help eliminate a bit of twist. We'll have to wait to see if this does the trick.
I oiled the wood well before heating it. I think this helps to hold the heat in and helps distribute the heat evenly.
I'll post pics of the results when it all cools down.
