I have the same 18x48 mini Tony.
There are a couple things to be aware of, unless he's made changes.
1. you can't tighten the couplers onto the ballscrews AFTER you've installed the screws, so make sure they are already on or you'll have to take it apart again. This applies to all his machines I believe.
2. The zerks on the ballscrews are tucked away as well, so grease them before you assemble the z and y axis. The x can be accessed simply by sliding a table piece.
3. the caps that hold the end bearings should be a slip fit, not a press fit. My x end caps were machined incorrectly and George had to send new ones out.
I've also got the 4660 running nicely and would be happy to help. I made custom brackets and paid 250.00 for the REAL Molex crimper, which makes things very neat and tidy.
I can duplicate the brackets here with the Bridgeport and make up the wires, which I have plenty of as well since they are the same machines.
I apologize for being rude to you in the past, so I'm trying to take a step in the correct direction. I have spent way too much of my life hanging on to grudges.
I also have more than enough of the EXPENSIVE wires that Clearpath recommends for their machines if anyone needs them...
