Clock

In the absence of the thicker wire, I wondered what would happen if I put the "twisty threads" balance on this escapement:

Answer: it doesn't work, flutters badly, loses energy. There are 2 obvious reasons:

1. the cotton thread stores energy so poorly that it's like having a super duper weak spring
2. the cotton thread has a natural twist in it, so the centre position isn't even with the thread completely untwisted!

I think give up on this idea. Maybe try taking all/most of the weights off the balance to see if that helps. But this is just an interesting side track anyway, because I already know this balance is nowhere near isochronous.

Other ideas are:

• connect up a normal pendulum instead of the torsion pendulum, shouldn't be too hard
• try to make a grasshopper escapement

A bit more on the loft:

Still needs:

• chimney holes connecting up
• chimneys should stick out above roof
• roof
• locating features for putting the loft on
• boxing around pipes etc.?

A start on the roof:

The texture on the roof is bringing FreeCAD to its knees, very frustrating.
