The helix is tricky, I benefitted from knowledge of two helixes on our old club layout. the first rule is to use the largest radius possible. It helps to use thick plywood, as any vertical curves (changes in the grade) on the helix will cause problems, and the thicker pieces of plywood are stiffer; and thus it is easier to keep the grade even. I'm not a math whiz, and figuring the grade , rise over run, or to be more precise, change in elevation divided my the length of the elevated track. To be sure, the english measuring system is going to put you into fraction land, so I figure my grades using centimeters. I have a measuring tape with metric on one side, and english on the other, so I can switch gears.
A problem that often gets missed is keeping the roadbed's cross section level. I have a several little levels, designed to be a line levels. as I'm building the helix (or any roadbed for that mater), I check the level, ninety degrees off the center line of the track. It should be dead level. some lean to the sub road bed you can get away with, but it is more problematic in a curve or on a grade, doubly so on a helix. a slight elevation of the outside rail in a curve is a prototype practice called super elevation. This makes the car lean inward some. the goal is to balance the force of gravity tipping the car inward, and centrifugal force, pulling the car outward. Super elevation helps a little on the model; but not as much as it does in real life. it is only worthwhile where you can see it, as it is a cool effect, but it is best achieved with tiny shims under the outside rail of flex track; we want to stay away from anything but a dead level .
The Lake house "Eagle's Nest", is awesome. It is on a steep hill in the deep woods, going down to the shallow end of a Bay on Kentucky lake (formed by by a TVA dam on the Tennessee River) The Bay be are on is where White Oak Creek comes in. I'm going to have to get a license and some fishing gear, the fishermen I know say that area is awesome fishing. We have a nesting pair of Bald eagles nearby, and we are seldom there without seeing or hearing them. If you get out on the water, you are very likely to see them, as they are fishing all the time, and ignore people in boats.
When my wife was commuting to Nashville to work on the pediatric Cardiology floor ant Vanderbilt, before she became a Pediatric Nurse Practitioner, she needed something weather capable to drive that could keep up with the 6:00am Nashville traffic, and our 86 Toyota 4 runner was imported when the speed limit was 65, and it did not like running 80 mph. I was working at a chevy dealer then, and they would sell cars to employes at $300.00 over cost. I had her come in and drive whatever the Chevy AWD station wagon was, but she didn't like it. They had an 03 6 cly Subaru Outback wagon, with the LL bean package, and she liked that, and bought it. The Subaru AWD tends to spoil you. Later she saw a Baja, and liked it. She asked me if She could get one for me, and I said she could if she got a yellow one. We are Nashville Predator Hockey fans, and I wanted a truck that would match my team colors. Ir took her a year hunting on the internet, but she found me one. My back up road vehicle is a 98 GMC Suburban, and My Wife has an 06 Red Miata for her back up. My farm truck is a 81 Toyota 4x4 truck, but it is not licensed , or insured for the road.
I painted the foam bridge pier, and put the first protective coat of polyurathane varnish on the river. the gloss acrylic medium looks beter, but has a fragile surface . when the varnish on the river dries, I can start installing foreground trees along the cliff, and making the primordial forest floor back to this corner. that is going to make this area my most most scenic spot, until I get to my upper deck. I have also shortened the bridge deck stolen from the club, and removed the code 100 rail (leaving the spikes in place, so it should be super easy to get the new code 83 rail installed); I need to cut out some holes between the ties to dump coal for the tannery. I should be able to start extending the track onto the Sander's switch block soon.
