Baseboard Construction With Helix
John has a question for readers on baseboard construction with a helix:
“If you are creating a gradient to take a track from normal baseboard level to a high level section and this gradient goes around a curve at one end of the layout (assuming oval form), then the track base is part of a HELIX!!!!
You cannot therefore use normal rigid baseboard material like 9mm plywood or chipboard.
What would other members suggest in this instance in order to twist the base material into the shape of a helix?”

I have used 3/4 inch (9mm) plywood to make the helix in my layout. The key is using a scroll saw (AKA Jig saw). I drew the outside radius on the plywood, then drew the inside radius, 3 inches inside the outside radius. I cut the circle with the jig saw. Yes it does use a bit more plywood. I discovered once into the project that I could draw part circles, cut the pieces out and get much better use of the plywood.
Hope this helps.
By the way, the jig saw is one of the most used tools in layout construction from my point of view.
John,
I really don’t believe you’ll have a problem assuming you keep the baseboard as narrow as possible thus allowing it to be ‘floppy’. By it’s own weight, it will have a tendency to form a natural grade anyway although probably not at the angle you would need. Also you will be placing support legs or brackets every few feet attached to the baseboard (I would think) to ‘force’ the grade that you need anyway. Remember that the track is also ‘stiff’ but it will be part of the helix as well.
I have seen articles is some model railroad magazines that have helix construction articles and I’m sure that there are many articles you could also find on the web if you look for them.
Hope this helps,
