Re: Hornby Elite Powering Lenz LS100s?

Do you mean providing power, or operating? For providing power, I would suggest using a separate power supply such as the Lenz TR100 available on Ebay for £20.

Re: Mainline crossing track question -

It was a safety requirement that facing points on a mainline required point locking mechanism. To avoid this expense at smaller stations, railway companies configured access to sidings in the way this diagram shows, I believe. It's a single slip providing access from the opposite side to the sidings...

Re: 3 WAY REED SWITCH

Certainly SPDT (Change over) reed switches are commonly available. But not 3 way!!!! Unless the OP means it has three connections? Which is of course the SPDT change-over type! I think invalid URL referred to above is actually this one, and it indeed refers to 3-reed change-over switches: http://ww...

Re: split chassis locos - how to tell b4 purchase

For a particular model it's worth looking at the assembly diagrams, which are listed here and which can show if the chassis is split:

Re: electric short

Could this be some sort of insulating plywood with a thin aluminium sheet buried in the middle? Does the problem go away when the rails are not connected to the screws at the edge of the board? Yesterday my wife brought me a mug of tea, and a Kit-Kat which she placed on the track of the lift-up sect...

Re: electric short

Surely the rails are insulated from the plywood by the sleepers anyway?

Re: Ply vs. MDF and is bracing avoidable??

I just used the planed softwood. Don't remember seeing the redwood and it looks as though it just has a better finish, but as you're not going to decorate it I don't see it's necessary. The main thing is to check that the wood is straight and true.

Re: Ply vs. MDF and is bracing avoidable??

Most people use 2x1 bracing, which roughly equates to the 44mx18mm size. That's what I've used throughout.

Re: Ply vs. MDF and is bracing avoidable??

I'm now thinking: http://www.wickes.co.uk/Exterior-Birch-Plywood/invt/164521 with bracing every 12-18 inches Yep - that's the stuff I used although the 9mm thickness. It has 7 layers bonded together, rather than the 3 of the cheaper stuff. This item is an 8ftx4ft board and I don't believe Wickes wi...

Re: Ply vs. MDF and is bracing avoidable??

Ook, so I think instead of just 6mm ply with 12mm MDF, i'll go for 9mm MDF with some nice bracing. I really would recommend you spend that little bit extra and use 9mm Birch ply instead of MDF. It will be half the weight, but because it's several layers bonded together internally it is much stronge...

Re: Ply vs. MDF and is bracing avoidable??

9mm Birch ply, braced at at least 18inch intervals, will give the best foundation. Bracing will keep the board stiff. An 8ft long board will be extremely difficult to manage, assuming you can get it into the house! If you compromise on your width a bit, then three 4ftx2ft 8in boards can be cut at a ...
