Reply to "(EMD) G scale engine CR (NS) SD80MAC build"

So a problem for me here, is that I have forgotten how I did some things. It's good in some ways in that I can improve a design without even knowing it. I have a vague feeling I did something a certain way and I attack it as if it was the first time.

 So I need to build the MAC's cooling fan assembly. I did something like it before

I think I overbuilt the whole section using 1/8" hard plastic. It is built like a tank! When I first started, I used a suggested glue and found some things were breaking off from handling. So I overbuilt the rest so that it could take a pounding. I switched glues and found that this section never even got a scratch after years of handling. When you have a shallow angle, the joint of the pieces is weak. If I re-enforce those joints properly, the box becomes very strong. Trouble here is something has to be cut to fit around each other and that weakens it again. If it's not removeable the glue takes care of that.

 So on this next build, I tried a sort of half cut box where the box is cut half way, and the long hood is cut half way thru. I forgot that the assembly does not need to be removeable like the O scale version is. I made my Gevo's fan cover removeable because it houses the speaker. This build has the speakers in the fuel tank.

My joints at the body are a little off so I will glue and clamp them tight to fix it. At least I got it started. I wasted some extra effort here.
