Engine mounting fixed
Dad finished the inserts for the engine; for where the threads were stripped. I glued them in, with thread-lock, a couple of days ago. We still need a new drive shaft.
wrinkles, but not so many
The October 12th blade has started to show some small wrinkles, but not so bad as before.
Maybe the foam was not well enough mixed? I mix it with a pencil in a cup for 20 seconds.
Maybe there was not enough foam, therefore not enough pressure.
I will mix more foam next time and release from mould after 3 days.
I want to see the weight lift a little, so I know there was enough pressure.

Left handed prop
I have built the old "DanCAM" software I wrote to design my prop blade.
I was hoping to cut a plug for the other blade direction, the left-handed one. The piece of wood I bought has twisted a bit, after being left against the wall, so I will need to measure the twist to take it into account before printing the paper profiles for it. It would be nice to rewrite the propeller part of the software as part of my HeeksArt software http://code.google.com/p/heeksart/

Another blade
I've got another blade in the mould, with foam in. I'll leave it for two weeks before touching it again. That will be September 12th.
