Making a little more progress. This is the inner primary plate. It's 1/8" 5052 alloy, and my first experience at aircraft style riveting. Still have to make the outer cover. I'm debating whether to try fabbing it up out of alloy, or make a plug, pull a mold off it, and make a glass fiber, or maybe carbon fiber, cover. Always decisions.

Got sidelined a bit by back injury, but back to work again. Finally got the wheels painted.

This is a bare wheel that's been cleaned and prepped with brush-on Iridite conversion coating, with the Rustoleum gold paint beside it.

Image

And this is my high quality paint studio, with the front wheel in process.

Image

And this is the painted pair. After they cure for a few days, I'll do a 2-part clear coat, and that's it.

Image

Time to order some tires next. The wheels are both 18", with 3.5" rear and 2.5" front, so I have some options.

Other than the wheels, I'm working on the plug for making a mold for the primary cover.

New tires mounted to wheels. Finest kind Shinkos in 100/90-18 and 130/90-18. I've used the same style Shinkos on several other bikes, and am amazed at how well they stick. And they last, too. I decided to go ahead and run them tubeless, even though the rims are meant for tubes, so they are now sitting for a day to be sure they will hold pressure, before balancing and mounting disks and such. If they don't hold air well enough, I'll use tubes.

Image

I also have the oil system ready to make hoses and install. Sharp eyed listers might notice that the hose ends are not new. I'm doing my best to uses up old race bits wherever I can instead of buying new.

Image

Still working on the primary cover, but it will take a while. Worst part is making a good plug to pull a mold from.

Love the aircraft fittings, properly done.

It's been a while, but I finally have a little more progress. These are pictures of the finished oil lines. I decided to go with the newer hose from Earl's, instead of the stock I already have. The newer stuff is still the same steel braid hose, but now has a black braided fabric protective layer. The 90° fitting I needed was on backorder for a long time, but finally came in, and allowed me to finish the lines.

Image

Image

Image

I've also managed to finish the rear brake rotor adaper, and am just waiting for some flat head countersunk titanium fasteners to come in to finish it.

This is the rear wheel with rotor and adapter. The rotor is from a TZ250 race bike.

Image

This is the wheel and rotor with the Brembo caliper I'm using. It's from an Aprillia, which has a slightly larger disk, so I won't be able to use the bracket in the picture, but will have to fab one to fit. The style bracket I use is pretty simple, so that part shouldn't take too long.

Image

I've been working on the fork yokes, so I can get the bike up on wheels. It was going well until I had a senior moment and bored the fork holes too large, so now I'm waiting for some more 6061 plate to arrive so I can start over. It's a bitch getting old.

I haven't forgotten about the primary cover, but decided I wanted to see the bike with wheels and such attached first.

Hey, it's all gotta get done. At least you're making headway. I'm at an impasse until the first of May or so.

Time for another update. I've been working on getting the for yokes done. This is a shot of the lower in the mill with the basic holes finished.

Image

And this pic shows the upper and lower with the fork and spindle holes finished. Also shows the location of the bolts holding the two bits together. It's made for 52 mm offset with no spacers, and can be adjusted to a max of around 68 mm if needed. 52 mm offset gives a 97.5 mm trail with my current choice of tires and chassis dimensions,which is just a bit more than a stock Commando. I think that should be pretty good as is, but if the steering is a bit too slow, I can add spacers to get it to suit me after the bike is running.

Image

Now it's time to get the rotary table out and try to make them lighter and prettier, as well as machining for the pinch bolts.

That's some nice work.

One of these days I'll get a lathe and mill...
