Here is my first Sketchup project...

Sweet. It looks like you have some reversed faces (dark grey as opposed to light grey/white). Are you familiar with the concept in Sketchup of face orientation? It doesn't matter much when you're only interested in getting a model but I remember it confusing the willies out of me when I got started and I tried applying textures to components.

I understand the concept of face ort. but don't know the implementation of it in Sketchup yet...

Simply select the face(s) you want to reverse, right click and select "Reverse Faces" from the context menu. You could also select one face which you know to be correctly oriented, right click on it and select "Orient Faces" from the context menu. This will let Sketchup orient all other faces according to the selected one. It doesn't always get it right, especially when the component has particularly complex geometry but in a model such as this one it shouldn't have any problems figuring it out.

If you make that out of solid wood the grain direction of the carrier rails will split at some point from the weight of the machine. You could add a plywood gusset as reinforcement. Nice sketch though good luck.

Agree with hightron. Make the carrier rails from laminated plywood, and use through bolts to attach the casters. I would probably house the floor boards into grooves in the rails also, rather than attaching them against the bottom.

Thanks for the input. I am going to try again. I am thinking about getting a LVL trust and using it as the side rails. I would still have to double it up on both sides.

the grain in an LVL is all oriented in the same direction you want alternating grain like plywood, you would have the same problem with the LVL as you would with solid wood.

Totally dependent on manufacturer. LVL is broad based in definition and non-proprietary including various grain orientations. Good to check on though, great point.

If you look at the second design I have gone with plywood after reading about LVL. Here in the Midwest we get both types single grain and cross grain. I know this to be true of the pile at my Menards.
