replace shortwave aerial insulator with spare porcelain unit and reseal tank overflow with

I’m replacing the shortwave aerial insulator with the spare porcelain unit from the shed — the old one’s cracked from salt spray and frost, and the signal’s been fading on the 49m band since the last storm. I’ll take the mast down at low tide, clean the threads with vinegar and a brass brush, then seat the new insulator snug but not forced — porcelain’s brittle, and I’ve seen too many crack from over-tightening. I’ll wrap the base in self-amalgamating tape before rebolting to keep moisture out of the threads. After that, I’ll tackle the tank overflow. The concrete pad’s been eating away at the base where the runoff hits — oak shims soaked in linseed oil, then packed tight with marine epoxy under the lip where the water spills. I’ll chip out the loose grit, dry it with the propane torch, then build up a little dam — just enough to kick the flow away from the foundation. Not pretty, but it’ll hold till we can get proper drainage laid in spring. Two jobs, one tide. If the wind holds, I’ll be done before dark.
