Default Show and Tell , Newest Project, OddRocs

OK So I've been feeling nostalgic for the southwest lately since that was where I grew up. That is why I built the wagon wheel. Also Can you guess which scifi television show that i have been binge watching lately ?

I really do believe that Foam-core is a very under utilized material for building odd rocs and science fiction based model rockets. It is incredibly cheap, and light , For the last 3 projects i have used less than 1 full sheet apiece from the DOLLAR store.

Can it be laser cut?

I only had 1 opportunity to laser cut foam core, and it didn't include any time to tweak the cutting speed and intensity. It does cut great, but the foam between the card stock shrinks back from the heat of the laser leaving a noticeable concave space, almost an eighth of an inch deep.

So that might promote gluing on something like this. Please disregard that this particular part is cylindrical not flat.

I suppose it does provide a space for glue to be, but I'm used to using elmers which shrinks. That extra space would be good for epoxy, but that would be overkill, for this light cheap material.
