More work on the point(s) today, the new one is now complete bar the spacer blocks between switch rails and stock rails on the slide chairs, which I forgot about(!)
I earlier mentioned tiebars, here is my wheeze for a simpler tiebar (yes, I know its not called a tiebar in the real world).
Brass wire bent up, filed to suit switch rail which has had its foot filed away to accept end of brass wire, part soldered in to brass tube, both sides done:
Piece of styrene drilled through and filed to resemble tube, this forms a central insulator. The two halves are then joined by supergluing multicore wire which goes up inside the brass tube on both sides. Pictured here before gluing.
The drive rod will be soldered to one of the pieces of brass rod. This is quite a good solution as there is a bit of "flex" in the tiebar structure which eases operation.
Next is strengthening and electrically bonding the crossing and wing rail assembly, first of drilling in to the rail, for which a sharp drill is handy as the stainless isn't very soft.
Next I drill out some scrap metal strip and having soldered brass wire into the holes drop the strip over the resulting pegs and solder together. This picture is actually the earlier point, I did the same job to that one the afternoon after completing the "new" one.
Next the switch rails have to be electrically bonded to the stock rails.
So I now have two useable points for the "quay line". I am feeling moderately virtuous in the having "got off my harris and done something" department...
Maybe more progress tomorrow....
