Hi,
just bought the kit for a mimic panel using Alpha Mimic LED switches for points. The track plan mimic will also have push-buttons to drive DC servo uncouplers.

I’d like to use a laser-cut control panel unit as advertised by various baseboard suppliers; these are constructed from 6mm ply. I note that the advice from DCC Concepts is 3 - 5 mm MDF. 

Will 6mm be too thick for the LED button shafts to bolt into?

If so, maybe the solution is to drill larger holes in the ply, and overlay it with, say, 3mm MDF, and mount buttons in that?

Any help much appreciated.
thanks.

It might be worth actually measuring the thread on the buttons to see if there is sufficient length to go through the 6mm ply + 2mm for the nut to grip.  {3 to 5mm does rather sound like not.}

Failing that, it might be worth contacting the makers of the boards, to see if they will make the Control Panel from 3mm ply.  Most are well up for a discussion on requests from customers.

Or you could simply counterbore the rear face of the holes yourself to a diameter to clear the nut.  I would use an end mill for the job to prevent snatch and arrange to set it up in some sort of moveable stand.  This is not as difficult as it might at first seem.

Then you only have to touch the rear face of the hole with the end mill to reduce the depth enough to clear the thread.  End mills are surprisingly cheap and easy to buy and, at that diameter, would be a parallel shank so would go in a small hand tool easily.

The button needs no more than 3 mm or you won’t be able to operate it. 

what you could do is fit the buttons to the 3mm msg and then mount it on a thicker material with holes for the cocker below

Thanks guys for the suggestions.
Given the physical size of the Alpha LED buttons both above and below the panel, what would you recommend is the optimum spacing (centre to centre) of parallel tracks on the panel itself?

On the site we have some stickers that are the same size as the switches great for panel planning

The DCC Concepts look pretty good.

I did a mimic in AnyRail, before the stickers, from DCC Concepts, were available.  The mimic [through rail] centres are 14mm apart, which leaves a space between the inner edges of 10mm clear [Blue and Orange].  The lines for the sidings are a couple of mm wider spacing [Cream & Green].
 The whole thing isn't particularly large, at 30mm x 20mm, so I just adjusted the width of the lines until they looked clear to see.  The spacing was simply applied so there was clear room between the switches, lights and the Text Boxes.  I also took the Ahjay's recommendation and took it to a company who could print and laminate it in one piece.  [The nearest, was a Staples shop, but not the only one.]
