This is how the mast is coming about - slowly, to be sure. But I'm surprised how well the horizontal branches are aligned after all the setbacks that are involved.
I use a hybrid method of soldering and Zap epoxy. Epoxy, whenever I feel that soldering would be too close to a previous soldered joint.
I think I got the mast too high after all - despite my conviction that in the plan the guidance was taking too high. The problem is at the bottom of the mast. So, there's no way to correct the situation without breaking what has already been accomplished.
I am working towards a construct whereby I can take the mast down backwards like in DELFI. Therefore, I made the stand one degree heavier than the weak-looking one that is suggested by Billings.
After quite a lot of work I realised that in my solution the horizontal bar that goes into the stacks - as per Billings plan - is not necessary at all. Then I rechecked the photos of DELFI and found out what the construct really is between the stacks. Now it's too late to change my solution to be true to reality and I'm left somewhere between reality and Billings imagination. After all the rod through the stacks adds to sturdiness.
The little horizontal slots are for aft deck light assemblies. The extra hole is for wiring of the lamps.
