Zee, Sam, Bob, Vernon, Dean, Jim, vascon2196, putputman, Joe, Dennis, Ron Gail & Philly, once again thank you ;D
Today's steam-up wasn't without problems...
Initially, I couldn't get Fred to even do a full lap of the track...
I finally tracked the problem down to the one big end rubbing against the wheel side, and that I'd set the clip retaining the pistons against the engine block waay too tight. Swapped over the pistons, and the rubbing disappeared while free-running. I also slacked off the retaining spring, and that had things going a lot better.
Too well in fact; at one point I got a bit reckless with opening the regulator, and that engine took of at such a rate of knots that the one coupling rod mounting pin came loose off the flycrank :-[
So I settled for a run without the coupling rods; no time to repair it today - here's the video:

During subsequent runs, I noticed that I get a lot of blow-by on the one cylinder when the loco is rounding bends; more rubbing of the big-end against the wheel because of the shaft shifting. So Fred's done for now, but not yet DONE. At a later point I'll sort out the little niggles; That's part of the fun ;D
I also took a couple of better photos with natural lighting before starting todays runs; those are below. I knew the first steam trials would take a toll on the finish of the loco; heat & water & oil drippings go everywhere ;D.
:big: - I was already asked "What's next ?" - so to preempt more of the same - a holiday, and then tidy up the shop; that will keep me busy for a while
. After that, I don't know yet; there's a couple of builds on my list; some depend on getting suitable materials, and others on some tooling updates.
