With a very solid steel down rod on the prototype I sincerely hope that it does not 'bounce' when returned to danger (although it might realistically sometimes be a bit less than playful coming off :) ).

I'm definitely interested in how it works - all such material is bookmarked for future reference :)

With thanks in advance,

Hello again :D

I hope this helps...

I started off by making all the parts of the return mechanism as you can see. The spring (4) was wound on a short bit of studded rod (as shown in a previous picture) and was made to be the same length of tube (1), the small disk (5) was also turned on the lathe, it was made about 1mm thick and was a sliding fit inside the tube (1) with a hole in the middle to fit the small tube (6). A small hole was hand drilled off center for the wire that is connected the the signal arm (3). The short tube (6) is a sliding fit over the signal post (2) and part (7) is a sliding fit inside part (1).
To start with I soldered part (5) half way down part (6). This is the part which one end of the spring (4) rests against. The spring (4) was slid into tube (1) with parts (3) and (2) inside. The soldered parts (5) and (6) were then added over part (2) and pushed against the spring (4) inside tube (1), making sure that the operating wire (3) was passed through the small off center hole. When everything was in place part (7) was then pushed up into tube (1) until it was flush with the base of the tube (I was lucky and didnt have to solder it in place but was planning to). When the hole mechanism is together I then made sure the signal arm was horizontal then soldered the wire (3) to part (6) being careful not to melt the join between (5) and (6).
Once all this is done if you push against either (5) or (6) the arm will change to all clear and when you release it the arm then returns to normal (danger in my case).

And there you go! Not quite upto Airfix standards but I hope it makes some sense!

A very neat mechanism! Thanks for posting the explanation.

What do you use to drive the signal? (Apologies if you've mentioned this earlier)

Hi Missy,

It was good to catch up with youat Bedford yesterday, and congratulations again on your award.

A minor point, but I know you are a stickler for detail, the base and the spike on the finial should be white only the ball being red. Unfortunately this is not easy to pick up from photos as they are often taken against the sky.

Cheers,

Wren

I'm sure Mick Simpson would appreciate this as a short article for the 2mm Assoc. magazine. I know many members who would be interested that don't do the interweb thing!

Missy - Congratulations on the Cup - When you place it on the mantlepiece, be sure to leave a space adjacent as me thinks that signal is going to win one next :wink:

Inspirational work as always - My MSE signal kits were going to be static...but you have just raised the bar again for us to aspire too :D

On WR tubular steel signals with the posts painted aluminium the 'spike' at the top of the finial and the 'stem' between the flange at the bottom of the casting and the ball itself were/are painted aluminium too.

Me again :D

Yes Mike, you are correct. I will redo the top bit when I get round to it. Just for proof...

Looks like some replacement loco valvegear. Awful small as ever. :) Love the signal. Real miniature engineering.

Cheers
