Sopwith Camel, 1:16 Scale, Model Airways by Script
This has turned out to be quite an undertaking. The Rotary Engine is a kit inside the kit. I am building the engine first to have something finished when I tackle the skeleton. The engine itself has over one hundred parts....all quite small. In fact, it looks as if it will be more of a challenge for my shaky hands than was the 1:160 scale Rob't E Lee.....
This is my first experience with Model Airways.
Engine.... the valve lifters and eyelets at the crank end are brass while the rest of the engine is britannia metal...been having a devil of a time figuring out how to hold the rods in place while waiting for glue to set. I've been through a number of types of glue...still looking for the best combination.
Looks like I'll be doing the whole thing under my inspection magnifier........
Cheers,
Jim

I've been looking forward to this one, Jim. I'm along for the ride.
Hard to imagine 100 parts just going into the motor. You're off to a good start, though.... Steve

Crowie, dalboy, hermit,
Thanks for looking in......nice to know someone is watching....extra motivation...
After announcing there were more than 100 parts for the engine, I thought maybe I ought to check. Well, I counted all the parts, not including the prop, and there are actually 127! Now many are repeat of the same part but they all require installation....With 9 cylinders, there are many 9 or 18 part attachments...1 or 2 to each cylinder....rocker arms, induction pipes, tappet seats, valve lifters, etc. And they are all so small I fear losing one to the vast wasteland called.....the floor!
Anyway, this is a busy visitor weekend so I hope to make some more progress next week.
Cheers,
Jim
Oh, And thanks to those who check the 'like' box. I find myself doing that as well many times...........

Hi Jim,
I have just embarked on the self same kit myself a few weeks ago, but am already finding it hard going because of the quality of the documentation. For example the valve lifters in the manual call for 15/16"x 1/16" brass rod, but the kit list shows only 1/32" brass rod for this purpose, and 1/32" is the only item included. It looks like you are using the 1/32" as there is clearly lots of gap in the valve seats around the lifters. I am sure 1/16" would work better... keep us informed, I will follow your progress with interest

Hi R2,
You are correct in that I am using the 1/32" rod. The gap in the seats only shows,to me, under magnification and does allow some flexibility in setting. This is one of my rare ventures into metal working and I'm learning as I go. As Crowe said, it would be great if you were to start a build log. I have also been custom cutting every rod as my lifters are quite inconsistent, using the tappet seats as a way to adjust for the differences.
Cheers,
Jim

Got a few more things started.....
Finished install the lifter rods and tappet seats....in the attached photo, there is a rod and seat missing....noticed when I took the magnified pic.......have subsequently installed the missing parts.
Painted the spark plugs...white insulators...first coat. Not sure if another coat will be necessary. Notice that all 18 plugs fit on the penny........quite tiny.
Have glued the propeller parts and once it dries, will be sanding and shaping.....finally some wood work....
Cheers,
Jim

Nice work so far Jim.
Looking forward to the rest of the build.

And if you do that, you will have enough to pay for something better"

Frank, Ian, and anyone I may have missed....
Thanks for stopping by and commenting. .....it keeps me motivated to get something done when things get tedious.........like installing the 18 sparkplug wires...
Wouldn't ya know that it'd take me to the last two cylinders to figure out the best process. At that point, I realized that using cut lengths and threading both at the same to to each was the simplest way. Oh, well.....now I know how to do my next rotary engine!
My next task is shaping the propeller. Not sure how much can be done with power tools so am going to take my time and try not get over eager chunking pieces of wood.
So here are some magnified views of the semi-finished rotary engine.
Cheers,
Jim

That engine is coming along great, Those plugs are nice and fiddly especially at such a small size let alone doing the leads, isn't it always the way just as you get to the end of section of the build you go and find a simple way or someone comes in and then tells you the easiest way to do it.
Well done on the build so far.
