MERG Turntable system with Peco N Turntable
« on: June 19, 2020, 12:21:24 AM »
Hi all,

Extracted from On My Workbench...
__________________________________________________

A fresh project is about to land on my workbench!

Peco N Turntable and MERG Kit 79+79C with RS motor and gearbox

Anyone on here with experience in using this combination?

NB-55 Turntable Kit
MERG Turntable Controller (Stepper Motor) (Kit 79)
MERG Turntable Control Pack (Kit 79C)

I have the MERG tech info for these items

A40/01   Stepper Motor Turntable Controller   
A40/02   Putting the Turntable Controller (Stepper Motor) Kit 79 to Use

These will be used with the recommended motor and gear from RS Components.

Unipolar 12Vdc 7.5 deg Stepper Motor (RS order reference 440-262)
250:1 Reduction Gearbox (RS order reference 336-416)

Comments appreciated as would photos.

No experience but something I've contemplated, so I look forward to hearing how you get on.

Hi

I use one on my layout

It works well but you do need to read the instructions a few times before the setting instructions fall into place, well I did, but once it sank in, all was fine.

The hardest part is mounting the gearbox but keeping the bridge level at both ends, you may need to employ some shims to a achieve a level bridge.

Other than that it works well.

Good luck with your build

Hi all,

Well - the tt arrived - so I've started!

First, modify turntable to replace dummy wheels supporting the turntable bridge ends with wheels.

Surprisingly easy, carve away the mouldings, leaving enough material to act as support for the wheels. Add additional support if needed.

Ensure bridge still sits level in the well and is supported by the wheels.

Add additional/cosmetic details to the turntable bridge, air/steam pipe for engine powered operation, add handbars for manual operation.

Set to one side, ensure time for glue to set.

Paint - not yet, waiting till I find photos to show how painted.

A query on this as may be all grey or all black or more fancy - anyone know?

I see order status on MERG says dispatched - hooray!

Photo to follow - still trying to make larger images show on forum and in the post.

Thanks
Phil H

Hi Phil
What timescale are you looking at? A fellow MERG group member, (Somerset), has asked me for assistance with his MERG turntable which is the same setup as yours. I already have an assembled PCB which I am in the process of setting up and running. Once I know how it works myself, I could give you some help if you need it.

Having revisited the MERG threads on this topic, I see that the PCB firmware can now be easily adapted to work with a cheap eBay 1.8 degree stepper motor, which is a fraction of the cost of the RS motor as specified above.

Hi there,

Yes, I read that as well, but the person I am doing this for was happened to have it use the RS components.

Hi Phil

Could you share what you did to add functional wheels to the TT bridge ends? I've got a similar project coming up shortly and any advice would be greatfully received. I know from a prior, non-modified attempt that the moulded wheels cause terrible friction problems and I don't want to fall into the same trap again.

Thanks!

Hi Steve,

A fuller write up with "How To" will appear shortly.

In the meantime...

The kit requires a 12v regulated power supply.

I know I can buy a ready made power supply, but that takes up a lot of space.

Ideas appreciated for a more compact power supply.

Thanks
Phil H

Yes - I can see that, but, as I said, it's a bit big!
