Ahead with caution..

Greetings.

 

I have spent this week doing a bit here and there on the railway board; mainly adding droppers for track feeds and attaching the cobolt point motor to the station entry section - though it is not as yet wired up to the turnout to supply polarity switching.

I used a double sided pad to initially locate the motor as advised, then found I only needed 3 of the fixing screws, partly screwed in, to make it a firm fit. I can't say it is exactly "quiet" in operation - though I have nowt to compare it with.

The motor at present continues for a couple of seconds after the blade has fully travelled - is this something I should be concerned about?

I wonder if it is something which can be adjusted via the slide plate which the actuator passes through?

I really am ignorant on turnout motors and wiring, I must confess.

I have some memory wire which I intend to play with regarding point operation, and also have been contemplating building a (scale) manual point lever for the yard points, which would be switched manually as the real thing would have been from the shunting frame.

Quite a challenge in terms of size and strength, but not impossible I hope! Sounds like a Missy challenge, n'est-ce pas?!

 

I am happy to have different methods on this one board, the intention was always to experiment with the unknown to some extent( I have always used wire in tube with peco points).

 

In the meantime I have some coach bogies to build to replace a right botched job in my first coach. It's funny how much more competent you feel after building a few association kits!

 

Regards

Chris not used cobalt motors but the similar tortoise motor will run until it stalls . If the point is free running it will move across and then bend the operating wire until the tension stalls the motor hence the overrun. Nothing to worry about. In 0 gauge I used a stiffer operating wire - no need in 2mm. The fulcrum for the operating arm is moveable and will adjust the amount of motion, moving towards the point should decrease the movement and hence the degree of overrun. The setting is not critical so long as the blades reach home before the motor stops.

Yes they are a little noisy at home but at an exhibition you don't notice it.

Thanks fro the information Don. That is a relief - something layout-based I don't have to go back over for a change!

Nobody warned me that actuator wire could be dangerous- when cutting it off and having it spring into ones finger...!! :(

Ouch, won't do that the same way again...
