I though I would start a new thread for my machine build, especially since it hasn't gotten off the drawing board. Might as well start at the very beginning, right?
A little background...
The machine will be a 5x10 router, used mainly for cutting cabinet parts. I'll use Ahren's solutions for linear motion, rack mounting and gantry support. The electrical portion of the design is still up in the air.
I've come up with a couple ideas for a machine base. I've run the idea's past JoeSantos, CarveOne and Ahren, getting their feedback on both and adjusting where necessary. Now it's time to solicit opinions from a greater audience.
Option 1 - Steel base and table frame.
Base-
~6" square tubing legs
~4" square tubing cross members
Table frame -
~1 1/2" x 3" steel tube
Table frame would be bolted to base allowing for shimming if necessary.
Pros - STRONG, stiff frame. The way it should be done.
Cons - expensive ($1800), I haven't welded (learning curve), warping of the base from welding, can I keep it square?
Option 2 - LVL base
Base would be constructed of 7 1/4" x 1 3/4" LVL's with doubled up LVL's for legs. Epoxied and bolted together.
Pros - Strong, cheaper solution ($450), easier to work with.
Cons - Stiffness?
So there they are. I havn't even gotten off the drawing board and I'm presented with a dilemma. Do I go the steel route or LVL? They both appear to be good choices, however each has their draw backs.
I welcome any feedback, suggestions, etc.!
Thanks for taking a look, hopefully this will be a build to remember. Either for its success or miserable failure!
Bob
