This is my second Fineline Automation router...My first was a 2x4, and this one is a 4x4 with the addition of a built in 4th axis rotary attachment...The rotary is a gear drive unit with a 4 jaw chuck, that has the head stationary, and the tail stock is movable and slides along the 4x6 aluminum extrusion..The actual working field of the rotary is 8x42...I have not as yet used it because I have been busy trying to make guitars...The rest of the info on this build is that it has a Vital Systems Hicon Integra 6 axis board, and yes I intend to add another axis as it is a simple matter now..It also has a 3HP 220V air-cooled spindle...It is running on Mach4 on a Dell Inspiron tower computer with a 24" Acer touch screen monitor …..I do not have a vacuum system hooked up to it yet, but I do have a vacuum system...I have a complete Pepperl + Fuchs Proximity Sensor Kit, but have not hooked it up yet and have not needed it, because of the way I am doing it now....
Back to the machine now..At least for me, I have found the Fineline units to be rock solid in use, and is built like the brick house you hear about...So far I have cut out 3 bodies and a bunch of necks with mistakes on my part, not the machine and it does so with ease....Like anything else that is related to this, what you put in is what you get out....So there is mine......
