thanks ray, I love your machines, will be interested to see the advancements. I love how the carts work with your present system too. I use your lighter return spring instead of the red one, and I know everyone says to take out the return springs completely but, my machine still starts at 4.8v no problem. and its mega quite because of it, which is one thing I always loved about your machines. anyway, cant wait to see what you have in store, brother.
