making skis?

[zachjowi]

has anyone ever used a cnc router to make the profiles of skis? is it possible to use a cnc router to cut the whole thickeness of a board even in multiple passes? using it like a saw?

another question is if I make a large 4x8 cnc router will it not be very precise for small projects

More money = more precision.

Yes.



More money = more precision.

but in general will a large mill be less precise? I have a sherline that is very precise but if I wanted to do something that is about 1'x1' on the 4x8 mill would it work ok?

thanks

A large mill can be every bit as precise as your small mill, it's the amount of precision that you build into the machine from the start.

So If you start with high quality parts with tight tolerances, you will be able to manufacture more precise parts in the end. With precision comes cost.

It's kinda like comparing a ballscrew, to a threaded rod (Hardware Store), it all depends just how tight a tolerance you need to hold.

Are you building a cnc machine to build skis, only? If so, you could save money by keeping your cnc machine working area just a little bit larger than your largest ski.
