Monday: While I ponder the cladding of the dome I am pottering around the octagon looking for earlier oversights. I replaced one larch plank where the original had ugly cutouts for an earlier trapdoor's hinges. The plan now is to hinge the trapdoor beyond the top of the ladder/stairs. Which meant I could close off the obs. floor sides close to the sides of the ladder. More larch sawdust and splinters later and I found I had to add two more floor joists to pick up the added planks nearest the pier legs. My timber is round shouldered. So I was able to slide the joists in on their sides and then bring them upright with a long Bessey F-clamp. Not without some effort I should add! Then the joists just needed a hefty tap with a lump hammer to set them to full depth. Now I just need to screw the flooring down onto them to finish the job.
Tuesday: Another warm and sunny day with hours of H-alpha staring at a rather indistinct sunspot. I am still waiting for the arrival of a low profile T2-T2, helical focuser. Plus a 2.6x GPC to tame the focus shortening of the binoviewer.
Apart from a little glue escaping sideways this went well by the time I had to put the saw away overnight. I need a sled to make repeatable miter cuts on the sides of the trapezium covering panels. Since the angles are all very similar, though right and left handed, there will be a need for small variations in the cut angle.
I shall have to arrange an adjustable push bar and a fence for the sled to make repeatable, angular cuts without waste. The panels are all under 60cm wide but will have to be laid [mostly] to one side of the saw blade for cutting. I'm hoping the 2'x2' sled top will be enough to support the panels without getting in the way.
