Hey man! Nice job! I'm thinking about doing the "moving" parts of my build in foam. What are you using for glue, if you don't mind me asking?
I just use a high temp hot glue gun from walmart both a large one for high volume and a small low temp one for really small parts with regular glue from there as well as it is relatively cheap and when it comes to how to cut and glue the parts together there is a really great video tutorial here: http://www.405th.com/showthread.php/37261-Foam-Technique-Tutorials Which will help keeping your cuts and seams clean when using foam
