about the "risks" -what is the point of this hobby if you dont do some things by yourself ah?
i need to know that i've build some of the gear in my model with my own hands.

OK, you go ahead, ofer. Build your air tank from whatever you find over there. Pop bottles, deoderant cans, shell casings, or soft drink cups.

There are always "acceptable or unavoidable" risks. And then there are STUPID risks. Let's all hope you continue to have hands to "build some of the gear in my model".

I'm shut.
