Helix construction, part 1: Roadbed

[battman5]

How didi you get the first layer at the right incline all the way around?

Can I ask how it rises up with each full circle of the helix - thanks

@slendersausage Hi, the wood blocks separating the levels are about 3" tall, so combined with the 1/2-inch plywood subroadbed, that's about 3-1/2 inches of rise per turn. That may not be enough clearance for modern equipment such as double stacks, but for our 1920s-vintage steam era equipment, it fits just fine.

Great video, very well presented you have given me the inspiration required to have a go and make a helix on my small British layout. Thanks a lot!!

Great video and very informative. I really like your idea with mixing the glues.

Jeff, might want to use the 'Link Video' function, so that the viewer can simply 'follow the link' to Part2?

Very nicely demonstrated and narrated. Looks professionally produced.
