Okay I am thinking about raising my Z axis even higher. I presently have the 12" Z axis but can really only do a total of 13 inches on my 12 inch indexer. I want to do more which I feel the indexer is quite capable of doing. I know I will have to raise my bed so the axis can cut accurately but that is quite simple. I am thinking of purchasing two pieces of 1.5" by 6" by 14' of aluminum side rails and extending my top V rail so I can cut on the Y axis versus the X axis as I now do. The price quoted by ShopBot took me by surprise but was wondering if I have another company as a alternative. Not that I don't want to buy from ShopBot but am curious. Any suggestions out there?
