John, I'm glad the 7-1/2" worked out for you. I used the Westcott book for benchwork back in the '80s. My first layout around 1970 was cookie cutter from an old Westcott book, HO Layout that Grows. I learned about risers and cleats there. I learned about splice plates helping my dad repair our old 1888 homestead, dating back to before my first layout. He never was a model railroader, but handy at jerry rigging repairs of any kind and saving a dollar while doing it. You have noticed on my Blackwater Canyon, I used Woodland Scenics foam risers for my 4% grades. I thought that would be easier since I only have hand tools. However, with 4% grades the 0% to 4% transitions proved to be such a pain, I am going to finish my layout modifications with risers and cleats. I guess an old dog needs to be reminded of what worked for him when he was a young pup! 
@TomSuperO your layout is really looking great!! I was thinking of you recently, but could only recall Tom, not your profile name. Trying to search members, there are a lot of Toms here. 
I must have been called away from the computer before I cam upon your name.
