I am not bragging but I can make anything. May not be professional quality but if I do not like how it turns out, and I am picky, I will not sell it. Making a boat in O or G would be expensice. Making the origional would probably take about 15 hours and if I made a mold and casted it The materials alone for O would probably run around 50.. G would be too expensive I am guessing it would be over a hundred just to make and mold one. The plastic I use is a dollar an ounce and the mold material is a little more. I can take a shot at it if you really want me to but like I said it will not be cheep. I had done a few tubs and rides in O scale but they did not sell so you would be buying the one and only probably. I do make an O and G scale Rocking Beam oil well kit that is motorized and looks pretty good.
