Ken, go ahead and start bring parts over and organize them in my living room, then set up a bed in your pool house... because that's where I'll be sleeping

I love this thread.

I did like the tail a little higher though, because streetfighter

Oven is for tempering plasticine clay. Tools are for carving clay. No idea what the horse hair looking stuff is for.

Hey Mike, good to have you jump into the conversation. Any cool Ducati projects going on with you?

Not sure what you mean by "tempering plasticine clay". I've never heard that exact phrase used. Please explain?

Correct on the clay tools

The "horse hair" looking stuff is actually Sisal hemp.

You'll be going with the Rizzla paint scheme then?

That took me a minute to figure out... but no, its not THAT type of hemp.

Rizla does have a nice team paint scheme though.

The missing ingredient finally arrived today... all 50lbs of it! That's much more than I will need for this project, but it was a great deal from a private seller who needed to unload a bunch. And it doesn't go bad, so it can be used on a future project (tail for my RZ500 frame project maybe).

Meanwhile after work earlier today some woodworking happened...

I've gotten a bit behind on updates, so hopefully this will get us up to date...

Last weekend (10 days ago) I built a removable sub-frame-like structure that will be used to support the tail buck. The buck is what I will be using to shape the new tail form. It is designed such that it can be attached and removed from the existing sub-frame via slip-fit joints. This is such that the majority of modeling can be done on a modeling board (grid layout) but then the buck can be installed onto the bike for visual reference. I hope that makes sense?

Anyway, here's the fabrication of the sub-frame/buck support structure.

I will be cutting the seat surround surfaces off of an R6 tail and adding that to the buck so that I have an accurate surface where the seat resides.

The final buck support will get layers of plywood, then built up with clay. The clay will then be shaped and become the mold buck for the new tail. Hopefully begin that process in a few weeks.

Here are the wood supports that will be used to support the buck. The tall support is angled to the correct angle as on the bike, while the lower support will be used when detailing the final shape as it will hold the buck close to modeling board thus being more accurate when translating reference points from side to side. That should make much more sense later on.

Some time was also spent last weekend to re-install the dual shock specific swingarm back onto the prototype bike. This required adding brackets to the new sub-frame that has been started for the that bike.

That same afternoon I made the left side exhaust brackets. Remember the CAD images of the three brackets ganged together... this is the laser cut part.

20210905_140828 by andbike, on Flickr

Then a little lathe worked followed by cutting apart and final edge cleanup on a sander.

20210905_150556 by andbike, on Flickr

Note the shims added under each jaw so that I could machine to the edge of the part.

20210905_153021 by andbike, on Flickr

The part is kinda flimsy so there was some bad chatter, but the chatter was worst on the throw-away area so not too worried about it.

20210905_153115 by andbike, on Flickr

I put the part back in the lathe for one last pass only removing 0.005" of material to clean up most of the chatter. They came out nice!

This past weekend I spent Saturday replacing the brakes on my wife's car, so this update is very short. I did get a little bit of time on Sunday, so made a fixture that will be used for locating the upper sub-frame mounting tabs on the main frames. Hopefully the process is self-explanatory.

Started with a crossbar that bolts into the mid-frame and connects to the shock mount.

20210912_135538 by andbike, on Flickr

Then arms added that locate the sub-frame mounting tabs.

20210912_150024 by andbike, on Flickr

Very simple fixture is done.

Stay tuned, lots more to come!
