John, I'm so sorry I didn't get back to you!!! Thank you for reminding me!! I inadvertently deleted the email reminder on my phone, and didn't think of it.
First off, PT is going well. I just finished 6 weeks of it already. I am getting some more flexibility and strength, and there is less back pain. In fact, very little back pain except when I get up in the morning for a half hour or so. My sciatic nerve is a different story, though I think I am seeing progress. I had a couple nights with less pain from it. The therapist told me I won't see a steady progress, but there will be ups and downs. I am taking a challenge tomorrow in that I am going to go to the Monroeville Greenburg show. I did okay a couple weeks ago driving to see my mum at the hospital which was a 45-minute drive each way. She got a pacemaker, and is back at her personal care home. I'm going to not take Rt 8 and Turnpike, but go an alternate route that doesn't take much longer, but I can stop whenever I need to. The trip to Monroeville takes about an hour and 15 minutes. The therapist wants a report on how I do when I go back in on Monday.
On to your wiring diagram. Following along, you did the same thing I did, except I only have one major terminal since my layout is smaller. Looking at all the drops, they all make sense, unless I missed one or two. However, if you missed any on the diagram, you will pick it up when you are wiring. That happened to me; I missed one and am glad I bought 24-terminal blocks and not 12-terminal blocks. I would have been one short on the sidings.
Have you made any more progress on the benchwork or had any thoughts on the backdrop?
