Me too, I can make 1 set on my CNC for me but it would be a nightmare to make 40 sets. Hopefully more people are interested, I will send a PM to everyone once I have the pricing for the cards. This is why I setup this thread, for the combined buying power, so this is a group purchase. The cards are custom sized and I doubt anyone could have made 1 or 2, but since there's about 40 of us, we were able to get the best in the business to make them (Slothfurnace).
When you get something CNC'd or waterjetted you're paying for the setup costs, which is understandable since it takes awhile to get the machine zero'd, material clamped, design loaded, etc.. Once its setup, the labor is minimal on any additional units made.
For example, one set of rails is like $90 cut from the waterjet, qty 2-9 is about the same. So 9 sets would be like $800, but 50 sets (100 rails) would be around $250.
I will also check the cost with my local waterjet guy, he is usually a little cheaper. Not sure if he can beat online pricing for something with such a high quantity.
