I use the Small Shop Bug Workstation Hold (2"), it goes well with my PE parts for 1:48 scale aircraft model - this Bug Workstation Hold is delivered with a direction of use, very easy to fold the PE parts.

I also use the Small Shop PE Part Rolling Set. A great assortment of tools for the radius, U-Shape, and cylinder shaped parts! The machined rolling channels are perfect for almost all my rolling needs.
