Hi

I'm into customizing motorcycles and I'm currently building a new rear end for my Kawasaki H1.
Early in the project I decided to use a rear wheel hub from a 78 KZ750. After a while I decided that this hub is uglier than a monkey's armpit, so I set out to modify the hub just to make it look better.

Here are some pictures taken during the process.

First the "before and after" picture.


I used the big press at work to get that ugly flange off.


Flange removed and hub sand blasted.


I made a two-piece mandrel for chucking the hub in the lathe.


Mandrel fitted.


Center drilled in the other end.


This is close to maximum diameter for my small lathe.


Finished hub machining.


In this mosaic picture I'm making a new flange to replace the one I removed. The flange is made out of 20mm thick cast aluminum plate.


The finished flange.


I made an interference fit between the flange an the hub. The flange will be heated to 200 deg celsius before placing it on the hub.


A guide pin was used to "synchronize" the spoke holes.


The finished hub, drive side.


The finished hub, brake side.

.

Great job. Very nicely done.

Mike.

I went to pick up one of my 1-2-3 blocks.
It was rung to the block under it.
They stayed together just long enough to get over the concrete and the bottom one fell on the floor.

When I went to pick it up, I managed to drop the other one

Well, at least they're still a "matched pair" ;~)

Got some of the vehicles put to bed for the winter. There is a 66 Mustang buried under a mountain of detritus in front of the Subaru and another motorcycle in front of the T-Bird along with the Bridgeport, all my welding gear, etc., etc., etc. Now you can see why I'm building a new shop. One more week and will be heading south for the winter, and only three weeks worth of work to due before we leave. Situation normal. Mike

Yup, you need a bigger shop.

Looks like you got nailed with the weather! I hope that doesn't greatly impair your new shop activities.

It's blowing and snowing today so I'll be working inside till it lets up. How's your shop organization coming along? Cheers, Mike

Mike,
looks like my old situation prior to expansion. You'll be a working fool again once your new shop is complete hahah.
You have organization skills and apparently want access to the Harley first!
Stay warm.

Making progress slowly. A new Hobby Machinist friend surfaced & is soldering my air system in the "big" shop. He lives on center drive a couple of miles south of the Norris School facilities. "Hippie" Bob has been helping to temporarily disorganize things so he can paint the walls. I have been assembling & hanging new 4' T8 fixtures in the little shop.
