R4-D4 Dome work progress 2.3

Last week, the last two panels have been worked on (17.11)

Panel 5 received a PVA wash, rasp work to take off the edges and sanding with paper (repeat until smooth). Wood filler was then applied, then once dried, this was sanded smooth.

Then it was onto the last curved panel. Trimmed it to fit along its edges (the clamped edge), then glued and clamped into place. First side.
Once dried, I glued the second edge down and then trimmed off the excess along the bottom edge. Then it was back onto rasp file work, and sanding smooth.

Friday I glued up the first edge of curved panel no6, I took the dome home and at the weekend I was able to finish glueing the second edge. Then a PVA wash and some wood filler, ready for work on Monday.
After sanding the filler and wood smooth, I gave the whole dome a spray with primer/filler.

Then on the lunchtime, I gave the whole dome a smooth sanding.

This process helps pickup areas that need small amounts of wood filler.
I also started on making the lid.


I had some luck re: on/off relay circuits. Thanks to pointers from fellow builders, it lead me to one which is now in the post to me. More on this when it arrives.

I have also been working on drawing up a circuit board panel to mount the trigger board, voltage regulator, digital volt meters and once it arrives, the on/off relay circuit board.

This is the second design. The on/off circuit board doesn't have mounting holes, so I'll have to attach it to the board via clips glued on perhaps.

Well, I wasn't happy with this version, so I re-designed and drew up another.
This has the fixing bracket already fitted with a screw location hole too.
