Foam XL hot wire cutter

[Boyan Silyavski]

I started drawing my thoughts up is there any difference running the linear rails on the side rather than top of the extrusion?

I think there is not absolutely any need the foam block to be supported by the structure . It could easily be simply on the floor or lifted by rests of foam. or a bed formed from foam leveled by the wire.

Same could be said for my design, but the cross bracing supports the smaller alu profile i am using against twist.

The problem comes when you have to move the blocks of polystyrene around, the blocks are not all that light and I'm dealing with 16' x 4' x 2' blocks so having a smooth and flat table to easily side them on to make it posable just about by myself were your method I probably could not. I allso will be putting mine in a 20' shed that has a wood floor so I need to build some extra strength into the design so it is self supported.
