Mystery model

[Jmk89]

I did some more work on the latest build today while waiting for the balsa to turn up, which it has now done, so this was an efficient use of time.

Today's task was to make the prop blank.  Here's a photo.


The wood is paulownia.  Since I had a block 300mm long to hand, I made the 400mm length by splicing 2 pieces 300mm x 38mm x 32mm together with about a 87mm long splice.  Then I remembered to wait for the glue to dry and to then drill the hole in the post drill before shaping the blank.  On my calculations this should give a 400mm pitch (i.e. P/D of 1.0).
