Mikes shop activities

Here's a list of all the current activities. Like others, I jump around too much to have a dedicated thread for 1 activity, so I'll toss them together in this word salad of all things going on in my hobby shop.

The longest "active" project is the radial. Started it 10+ years ago. Didn't know squat about machining, cnc, etc. Been a learning experience. Lots of parts and need to remake a lot of them, but its getting closer. Optimistically - maybe a year or 2?

Next on the list is the B1 Springbok 5" gauge live steam locomotive. Bought as a chassis running on air. I've so far built the tender body 80%, and soldered up the insides of the boiler. Next up is boiler assembly, going to be a big job and waiting on spring weather to have a go.

After that is a Worthington duplex steam pump. I got distracted building the B1 boiler and needed some machining time, and the radial was at a difficult place for me so I started something new. This one is about 90% done. I may actually finish it...its all small but time consuming parts left (tube fittings, check valves and some silver soldering.)

Then its mostly either new things I shouldn't start yet, or tool / workshop fixes / upgrades etc.

In the list of things that I've started the mental exercises but really should not start until the above are done:

Gauge 1 (45mm between the rails) live steam "Green Arrow" locomotive (2-6-2) - fair amount of CAD done on parts I'd CNC
Some design work on making a functional direct injection diesel in small scale (~22cc - 28mm diam piston x 35mm stroke) - because I like a challenge...
I also have castings for a 1/4 scale Wright Whirlwind 9 cylinder for when I'm bored
A 3.5" gauge Britannia Duchess part built chassis as received by my dad, who gave it to me to finish as he's smart enough to know when he has too many things to do.

Hopefully I'll be sharing some progress and wins along the way.
And pictures, always pictures. After this week at work I have had it reinforced in my head that nobody reads words

Which radial is that ?
Guess you didn't think a three or a five cylinder might be a gooder starting project. ;)
Yeah, I know, one of the more difficult engines out there to build..
Its a Pratt and Whitney Wasp Jr. (R-985) in 1/6th scale. If being 9 cylinders wasn't enough its a smaller scale than most making it more like watch making at times...
 
Thanks, I think it looks nice cause alot of the glamorous parts are castings I bought (cylinder head and front crankcase). Doing my best to not mess them up as they are no longer available. I'd love to get one of the heads 3d scanned so I could make a new one, drawing it is such a pain...

Nice. I think I've seen your Wasp pics on one of the ME forums. What's the history of yours? When did you get the parts? Were the plans 'serviceable'? (I seem to recall you did a CAD re-do).
I think Bruce Satra was one of the the Wasp casting guru's, but I also seem to recall others have modelled the Wasp in other flavors. I wonder what became of his wax casting dies & such?

Recently I was digging in my storage box for some obscure magazine back issue & found a handwritten reply letter from Bruce when I was contemplating his single as a starter project. I think I had just got my lathe around then & didn't know which end was up, never mind taking on a jewelry casting. So I passed. Probably made sense at the time, but OTOH it would be nice to have a small piece of model engineering history. Well I hope you keep pursuing yours. I am familiar with the 'its almost done' syndrome, there is a lot of work in those little buggers.

Cool, only familiar with the 1:1 scale and those are great. Very impressive job Mike.
