Your cleaning is definitely praying of, George @gblair
Each prepared part adds a lot to this build.

Parts are coming together and they are actually looking like something recognizable. The engine parts were sprayed with Airfix Aluminum from a spray can, then I painted some individual pieces with Vallejo metals to give them a little different appearance. I also discovered that you can brush the Vallejo Metals onto parts with good results, even though it is supposedly airbrush only. I used several Vallejo weathering products for engines to make the engine look used. Tomorrow the frame and engine will come together. Yeah!

Yes! The time came for your BMW to come together, my friend @gblair! Your fantastic job in all sib assemblies paid off. The result so far is superb!

Thanks, everyone.

Michael (@faraomike): It is an exceptional day when you can see any portion of the top of my workbench. Building models for me is more like a full-contact sport. Of course, this leads to mysteriously missing parts.

Spiros (@fiveten): All the prep work and pre-painting is finally paying off. Since I don't know anything about motorcycles, I spend a lot of time going through the instructions and online photos so that I am sure what goes where and what color it is.

George (@chinesegeorge): I am getting excited that there are assemblies that are actually starting to look like something on a motorcycle. I had my doubts for a while. I am hoping to be done with the bike next week, but that might be ambitious given my slow pace on some of the assemblies. I am trying to decide what I want to build for the Hawker Group, and then I want to get rolling on that next.

Nicely coming along, my friend @gblair!

Sorry for not replying earlier on your excellent progress, George @gblair
Had a long weekend with my family in Barcelone, so barely time left to check iModeler.
Your work on the engine looks great, starting to become an original one.

Got a little bit more done. Added the cylinders, spark plugs, and a bunch of wiring. Things are starting to fill out. Next up: the muffler and pipes. I painted them a dark steel color, and now I am adding some rust and other stuff to them. I thought it might be better to do all of this away from the motorcycle, since I don't want any errant weathering rust to go flying into the wrong place. Cheers.
