Seeing how I can't Ich spreche kein Deutsch (Speak German). I was wondering if someone here has purchased AFV Models Leo 2A6 idler wheels (AC-16-319) and could tell me in the universal language on how to assemble them. What I'm looking for is:

1.) How do adhere the end cap to the wheel shaft. Do I use Lock-Tite or does it lock in with pressure applied?

2.) The bolt ring the sits around the wheel shaft, do I CA glue that on?

3.) For priming the metal, could I use an automotive etching primer or Tamiya Metal Prep spray, then follow-up with NATO Green?

4.) Should I prime, paint and assemble first or assemble the complete Idler Wheel and then carry-out the priming and painting process?

5.) Is there an easier way to cut the flash of the rubber wheels?

Thanks in advance for any assistance.
