Thanks blokes.
Yes Jim, I'm more or less working in imperial myself, as well as the x1.5 size and reworking some parts as I go along.
I seem to be spending a disproportionate amount of time on these beams, but as they are such prominent features I want to get 'em pretty right.
So the paint in the recesses looks like taking forever to dry, so I'm held up. Make a start on the crank arms. I wanted to do these in cast iron, but no suitable bar about, so ....
.. a slice of 3" bar and some creative bandsawing,
.... gives us a nice little block to make the bits out of
This is a turning fixture, I have accumulated several of these over the years, it will come into play shortly.

It isnt always about 'the most convenient' way, its about making do with whats available, this is exactly what got me into casting in the first place (was that really 1983? wow).
Looking good bloke, you certainly dont muck around..... I do enjoy your no bullsxxx posts. After the success of your twin I would think you could have been forgiven for takling a rest and basking some.... but nooooo.... Onward, ever onward....

OK, with the block still in one piece the various holes are dealt with
And then sawn from the 'parent'. The top hat bush in the foreground is an adaptor to fit the blocks to the turning fixture - it kills two, nay three, birds with one stone - takes up the difference between the 4mm screw in the fitting and the 5/16" hole in the block, holds the block to the fixture and serves as a guide for the turning.
A block is mounted on the fixture
and half the thickness turned away
One down, one to go
Now out with the trusty file -
We still have the crank pin ends to deal with, which will involve another bush and more filing - perhaps tomorrow.

Pretty much a lost weekend as far as progress goes. Got the crank arms finished
.. and put on a couple of rough, temporary rods to check clearances etc. At thi stage we have a rather elaborate finger engine ;D
Made a start on the real rods

The Rockley Mount fire is about 3km away, as the crow flies - been a bit of a worry all night, but the wind is somewhat in our favour and it's burning more across us than towards. Last (oral) report is that they think they have it under control, but the roads are still closed and large policemen are enforcing the closures. To top it off, the fire bought down the power lines last night, so we were without electrickerty until the early hours of the am.
