Thanks guys! 


Lots more holes to drill, got a start down the sides of the spokes....

Do you ever get where you look at what you’re doing and declare “wow man, this thing looks like an excellent candidate for the scrap bin?”, only to perceiver and have everything come out ok after all?

The destination motivates us toward excellence, the journey entertains us, and along the way we meet so many interesting people.

Not too many, though there are a bunch where halfway through I realized that I was doing it the hard way, and could have been done if used a different way. Usually the ones that get turned into RC boat ballast are the ones with a fatal mistake, something the wrong size or broken off, holes in the wrong place, things like that. Still have some partly made models that still get scavenged for parts.


I do recall one ship model, got a quarter of the way done with the rigging, and I just stopped. Didn't have any inspiration for it anymore. Took a while to realize why -  the size thread I was using was too thick, everything looked chunky and out of scale. Cut it all off and started over with finer thread, was much happier with the results. Few weeks gone, but learned a good lesson.

Continued on the spoke shaping yesterday and today....

finished them up this morning

and got all the bolts out and the plates numbered for where they go on, since that many holes will never quite line up in any orientation

Next step is to put the aluminum center sections back on the mill, and enlarge the openings so that the plates will overhang like on the front wheels. Then put all those bolts back in....

Put the inner spoke plates back in the mill, and started by taking the rim width down - the one on the left is cut down, one on the right still to go:

Then went around and took .075" off both sides of each spoke, and took the inner arc back to match. Lastly set the rotab up vertically, with a spacer block underneath so the plates would clear the mill table, and drilled/tapped 5-40 holes in the end of each spoke:

Likewise drilled clearance holes in the rims. Note that the holes are offset from center of the rims, the spokes are set back farther on the inside, which gives clearance for the leaf springs later on.

Then, spent a while putting all the bolts back in to hold the outer plates on, and used the belt sander to shorten the ends above the nuts. Lined up the spoke assemblies with the holes in the rims, and bolted them in with some loctite 638. After that sets up will cut/file off the screws flush with the rims.

After trimming the screws, I can bore the center holes out to final dimensions, holding the wheels on the faceplate again. This will ensure that the hub holes are concentric with the outer surface. After that, still need to cut the tread slots in the outer surface of the rims, and can start work on the hubs. I think I am going to use taper-locks on the inside of the hubs to hold them to the axles - will be useful to be able to easily remove the wheels from the axles when working on the differential and suspension parts.

So, while the loctite is curing, good time to head out on the porch for a read/nap in the rocker!

Thanks Don.  I've never made a flywheel quite this way, the MEM Corliss one was close, but the spokes slipped through the rim. This seems like a good way for large diameter ones, as long as suitable pipe for the rim can be found. This A36 steel cuts okay, not great but good enough.

After letting the Loctite set up, got the screw heads trimmed off, then set up on the mill to cut the slots in the tread. Just like with the front wheels, did one wheel with the rotab angled one way on the table,

then turned the assembly the other direction to do the second wheel, so the treads are opposite angles.

Next will be to move back over to the lathe to bore out the hole in the center to final size for the hubs...
