i am going to have to agree with this point over foam filling. i never intended to have E.G. be the main structure of the build but wanted to gain the dampening and stiffness gains from and assist to the steel frame work. extra weight is a good thing when it comes to machines in general.E,G. is nice because you can do it pretty much anywhere and nothing special is required for the most part.
