How to Layout Hold-Down Rails
« on: March 18, 2022, 01:01:02 PM »
The attached pictures show the table where my new cnc will sit (this is the support table). This top is 42”x30” but the top of the cnc will be less, approx. 34”x27” and the cutting area will even be smaller.

The 3 small aluminum rails shown are 19.5” long each and the single one is 42” long which I will cut to make 2 more 19.5” long rails, so I will have 5 rails each 19.5” long.

The question I have is which way will be more practical to lay these rails, front to back as shown in one picture or left to right as shown in the other picture. The space between these rails will be filled with 1/2" plywood which is the thickness of these rails

Thanks

Nicolas

Sorry, I forgot, how about the spacing between the rails, should I space them evenly or have them closer to the cutting area?
