Jeanine,
I don't know if any of this would be of help;
As I had mentioned in Studio Tips, I had originally made a unit where I had framed in a flatfile (with 2 X 4's) and had a plywood top. This was mounted on casters for mobility and was also used as a model stand, matting surface, etc. When I acquired more flatfiles, I did away with this setup and just stacked the cabinets in the corner. (Gee, where did all the space go?

)
Now I just have a piece of three-quarter plywood (about four feet square that leans against the studio wall, (takes up no space) and five concrete blocks outside the studio, which I bring in and place underneath (vertically) when I need a model stand. Daniel Greene used the same method at his workshops, and it sufficed. It's not as "elegant", but since I don't use a model stand that often, I couldn't waste the space. Ken
