Dave,
Regarding a form for bending the rails, I initially considered buying a special track bending tool. However, most of them that I looked into were either fairly expensive or not suited to the Scaletrax-size rail, or both. I think Dave Hikel and his team use and recommend the Llagas Creek bender. I came close to purchasing a bender made by Norm's O Scale several years ago, but production stopped before I bought one. In the end, the hand-bending technique worked fine for my needs.
Regarding RRNEWBIE's points, I agree with him to avoid the Scaletrax lockons--just solder the connections and you'll be happy. I spent most of my life in Northern California and didn't build a layout until moving to Virginia several years ago, so I have no insight re Scaletrax availability in NorCal. I've ordered all my Scaletrax items from retailers here in the Mid-Atlantic region or found needed pieces on eBay. I have never found what I needed track-wise on DASH, but per CSam, there are apparently some Scaletrax items available on occasion.
Yes, I used the Woodland Scenics risers. I had some experience with the cookie-cutter method of elevating track, but it was going to be a challenge creating the grade I needed by cutting the 1/2" hardboard base. I had never used them before, but I found the WS risers easy to work with and a perfect choice for what I wanted to do with the elevated branch line (to what will eventually be a logging camp operation). WS makes a wide variety of O scale-size products that are easily mixed and matched to suit your project. At 2.5" wide, the risers work well with O scale track and the Midwest cork roadbed I used. I will definitely use these risers in the future.
I would still use Scaletrax again. It certainly has the drawbacks cited by others, but there's no perfect track system out there. While I really admire what can be done with handlaid track from a realism standpoint, I don't have the time or the skill to attempt that--even for a small layout like mine. What keeps me in the Scaletrax camp is the realistic rail height; the general ease of use, especially of the flex track, is also a plus in my view. As long as MTH will produce the line with #4 and #6 switches, I plan to stick with it. One of my winter projects is to install ground throws on my switches.
Let me know if you have other questions--it's an interesting discussion.
Tony
