Dome bogged and sanded
So, since yesterday the dome joints have been filled with builder's bog and allowed to set. From lunchtime today I have sanded all the joints down to a nice smooth finish ready for fiberglassing, may wait for the holidays before I start that process.
Other than the fiberglassing the shutter is the next major task. So, the plan for this stage is to cut out the appropriate quantity of plywood arcs to form the frame for the two shutters, top one rolling and the bottom one connected by a hinge, simpler to the Sirius observatory dome.
For the tracks which the top shutter will run on I plan to lay aluminium flat bar along the shutter frame opening, then a strip of timber then another layer aluminium flat to create the track for the shutter to roll on. As for the roller, I have a quantity of 20mm Flat rollers for the job.
Cheers
