Well as painful as it was to spend another $2,000 I just purchased a brand new Carvewright cx and will now have 2 machines. I'm going to fix up this C machine on the side when I get some extra cash to throw at it. Now the 10 day lead time wait and 3-7 days shipping is going to be rough waiting but at least I'll be able to catch up. I spent the last 4 years building up a nice list of regulars who contact me every time they go to weddings, baby showers, every Christmas, etc. for custom signs and recently I've had to turn away a few orders so to keep having this older machine go down is more expensive in the long run.
On the bright side I now have some time to work on the shop.
