That's a great use of a weight rack.

I never did update on the flat tracker build. I finished up all of my parts for it a couple of months ago.
Started by simplifying the design and cranking out a set of offset rake triple clamps:
I don't want to press bearings into the steering tube until after the frame is powdercoated, so I turned some temporary nylon bearings just to get it rolling:

That looks great!!!!
You've definitely got some skills.

Unfortunately, the steering stem I turned out of some chromoly tube is too short for the thick nut I bought for it, so I'll turn that nut down to be shorter when I regain some giveashit:

The rear end of the bike was a more complex problem. This bike had drum brakes and a completely different wheel, so every part back there had to be designed from scratch. Started with capturing a point cloud of the existing swingarm ends to model from:
Was able to use that to get the whole setup modeled:
Would have a modern chain adjustment system, disc brake. Oh, and a Harley Davidson front wheel in place of the old Yamaha spoked rear wheel, so adapters both side for the sprocket and brake disc.
-
Started with the base of it all, the chain adjusters. These pictures show temporary flat head socket screws holding them on. I've since faced those screws to be flush on both sides. There are tabs on the bottom for later attaching swingarm spools for a rear stand. The tab on the back of the right adjuster is for preventing the caliper bracket from rotating. Kind of like a stock sport bike setup.

Sprocket carrier:

When are you going to design the Hardcore Husky motorcycle?

Brake rotor carrier for Galfer rotor that I had laying around:

All the parts put together:
Unfortunately, I had the same problem at both ends of the bike in that the custom parts require longer axles, so I had to turn a pair of them out of some more chromoly tube.
