Traverser Table FY
traverser baseboard fiddle yard
Just as a reminder, I used drawer runners - the ball bearing type - available from most DIY chains.
The traverser board is in two parts - it has its own baseboard and a running board joined by the drawer runners.
It is critical to keep the runners parallel or it will just jam. The running board is 33 inches long to take a 3 car dmu and overhangs its baseboard on the operator's left. It is 8 inches wide - enough for 4 parallel tracks or 5 at a push. This is it lying loose.
One of the reasons for having the traverser demountable is my lack of operational space. As you can see I have to pull the layout out into the access area to have the traverser mounted. This will be even more acute a problem when the boards are round the right way - the station board in the corner. This shows the traverser well in the factory board. The holes in the cross beam are to take the runners as they slide across. The depth of this well is quite critical so that the top surface of the mounted traverser is at the same level as the main baseboard across the full width of travel. Doing it this way does give the option of adding shims of plasticard (though none was required here).
The running board extends out so that it will be possible to align all tracks with the track nearest the back of the board. The input tracks (there are 4) will be offset towards the back so that at least 3 of the tracks on the running board can be aligned with the "up" line of the main.
The track and alignment pins are yet to be added - and I will update this page when that is done. However, it will be a while as the factory board will be set aside while I concentrate on the station board.
