Re: For the surfboard guys

Unless you have a 4th axis to rotate the board you'll be wasting your
time with CNC. You will find two things to be true.

1. Once you go from a block of material to a free form shape you
will never be able to hold it in the proper position.

2. The second you unclamp anything or remove it from a referenced
axis you will spend a huge amount of time getting it referenced again.

The key to any CNC application is to let the machine do as much work
as posible in a single shot.

so, back to the design part.

Ditch the "table" and mount a rotary axis in it's place.

We're wandering into off-limit take though, if you want contact me
offline at admin@... and we'll continue this.
