I've just built a table top for a cnc mill using 1x3 of the lite. I guess that would be 1030 and am completely satisfied with it. I also have some 2x2 of the light and am completely satisfied with it. Obviously the non lite will be more rigid, however, the light shouldn't be looked at as being an inferior product. If you're looking at whether the light or regular will cause racking or flex, I'd look at the design of the machine first. Either of them will work fantastically in a well designed machine. Neither will make a bad design better. I've seen 80/20 builds that have had some racking and flex problems using the thicker version.
I just looked at the top and realized that this thread is over a month old. So what did you end up with? |
