Master Bodge for Gn15 Layout (or Maybe Gnot)

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Master Bodge for Gn15 Layout (or Maybe Gnot)

Postby Gerry Bullock » Wed Jul 20, 2011 1:07 pm

As Andy A is the Gnatterbox recognised Bodger I thought the time had come to challenge that title.
The following mock-up will feature in a Pub Garden featuring a Wibbly Wobbly Gnomy with child on board.

Yes it does work but, currently I've run out of hands to apply power and run a video shot.
So little time, so many ideas!!!!! GerryB.

Looking forward to seeing it in motion once you have it all wired up.

Ah but when you get to Gerry's age Courage and Bravery count for little.

One simply does stuff with abandon :wink:

Great Idea Gerry, very creative.

Thanks for comments, not sure about the "Abandon" bit Michael. Hopefully the "Hell" bit won't apply either. :lol: :wink:

I did say it worked and here's the proof, now have to complete basement railway before cracking the assembly of this unit onto the upper baseboard.
I plan to make it removeable to preempt any potential failure.
It will be switched and thus powered by batteries. Haven't decided yet whether to let the kiddies operate the switch.

It does run more smoothly than the video seems to show.
I claiming this animation as a first for any Model Rail layout.

:lol: Brilliant Gerry :D
I think you can blame the jerky video on photobucket, their servers are not really fast enough for video. It is a lot smoother playing for a second time.

Gerry I thought that the machine would not only go up and down but wobble a bit side to side, perhaps it does that but not apparent in the video. Still brilliant by the way.

The wheels seem to be in line and not quartered on the drive mechanism.

G'day Gerry

Just seen your video and loved it. :D

Just the sort of thing that I would love on one of my layouts.

Although I must agree with Michael that a little side to side motion would add an extra dimension ..... maybe you could rotate one of the drive wheels a fraction :?: :?:

Regarding the control of the motor ..... if you decide to let the little kiddies control it, might I suggest that a simple time delay (like a 555) would be a good thing to install.
This would stop the little horrors from trying to control the speed of the motor with a crude form of pulse width modulation by 'pulsing' the button :!: :!: :!:
(Don't even think of asking how I know that this will happen.)

Cheers

Thanks guys. There is, in fact a slight variation in the con rod position as I didn't get them exactly in line. The Loco does therefore wobble slightly from side to side.
As the Gnomy is only located at the front using a masonry nail through the coupler it does tend to tilt to one side as well.
When making up the final assy I'll have to restrict the conrod apertures to ensure that any tilt motion is minimal.
Many thanks Adrian for that suggestion, my Electronics Wizard is au fait with 555s and has already used one in the control system for the basement railway.
I'll post a photo of that box of tricks on the Gneiss Cider thread.
So little time, so many ideas!!!!! GerryB.
