Choc blocks vs Snap lock connectors

Relocated the wiring beneath the test board today and soldered the connecting wires to the points motor - which formerly had been tied to the terminals of the motor.

Underneath the test board.

Underneath the test board.

You can see that I have used choc blocks to connect wires. I think I will stick with this method rather than use snap lock connectors; and for the following reasons.

a)  they always work and are easy to use.

b) if you change your mind about which wires should go where, you simply unscrew choc blocs and re-connect accordingly. Snap lock connectors cannot be undone because their blade cuts into the wires AND they completely encircle the wire so to remove one you have to slide it along to the end of the cable. But if that cable is joined up to anything else eg a points motor or another cable then that has all to be undone.

c) despite what certain people say, I still find snap lock connectors  unreliable. The blade within them either cuts through the wire entirely or doesn't penetrate its plastic coating sufficiently to make the electrical connection.

And the nice tidy top of the board now looks like this:

Schuberts's Moments Musicaux

I cannot imagine anything more beautiful than Schubert's set of 6 Moments Musicaux. Have been listening to Radu Lupu gently pawing them out of the keyboard.

The second of the set is particularly heart-breaking.

The Scottish Book of Common Prayer (1929)

Also known as the Red Book.

I opened it at random yesterday and found these words: "Regard not our sins, but the faith of thy Church ...................."

It put me in mind of Purcell's: "Remember not, Lord, our offences."

Henry Purcell (1659–1695)
Remember not, Lord, our offences,
nor the offences of our forefathers;
neither take thou vengeance of our sins:
spare us, good Lord, spare thy people,
whom thou hast redeemed with thy most precious blood,
and be not angry with us for ever.
Spare us, good Lord.

Here is a clip of a choir singing the piece  in Leeds Parish Church.
