Very nice build, looking good.  .

Thanks Dave,
Black Marker pen, it will stain the wire surface, virtually no thickening.
Rac > Yes, my last build followed Rolfs model, the 10' F5. This build I've picked up the wire spider ( I may modify the 10" as well, I bought extra Machine Heads and 'E' strings)
If you are referring to his swivelling pivots for the machine heads, yes, I was aware of them. But another comment he made was how stable and rigid the secondary was in the wire spider. It holds collimation and under normal use shows no movement at all. By coming through the UTA rings with the spindles and matching the alignment and wire clear side on the spindles of the machine heads they all align and free float without the need for any more mounting hardware. My UTA is therefore shorter and lighter. Also this is a 6 strut build rather than 8. Saves weight again and aesthetically it just looks better matching with the mirror cell bolts which always bugs me with visual alignment of all the nice hardware. Yeah, I know, a bit OCD ..
I may need to adopt his method if I convert the 10" as the build specs are different for the UTA.
Hopefully this weekend I'll get the upper trusses done and assembled and you can see the whole beast. I'm kind of impresssed with how nice it looks and how well it has come together myself. A rather satisfying project.
And if this version of the spider doesn't work as expected I can easily build a conventional 4 vane, more fun workshop time.
