I had a party run through Long Arm of the Hutt and my Technician would like to assemble the droid parts found in the cargo hold of the Krayt Fang to make an astromech droid. I know the text says that the characters shouldn't have the resources to do this, but my player is insistent.
For now I'm allowing him a hard mechanics check every 3 hours representing 3 hours of dedicated work to make or hinder progress on the droid. How many hours of successful laboring should it take to put together an astromech droid? Or should I put different rules into place? Any thoughts would be greatly appreciated.
