I can speak with some authority on this subject, as we have old school manual machines and some high end
CNC machines along with the Patriots.
In the ad, they say the machines have " too many knobs and levers". its a funny comment, but leads me to believe that they were expecting something like those little desktop units that have no mechanical functions. I'm not familiar with the Bridgemill model, but the Patriot is fairly complex with power gearboxes on all 3 axes and the hi-low spindle brake mechanism. For those not used to the old school methods, it could be a little intimidating. The 3 in 1 machines serve a very important function in the tech ed system. They are low cost and offer lathe and mill function in one, allowing more hands-on student time. The real advantage is in the " weeding out" process. Only about 1 in 10 students who sign up for machinist training will eventually graduate. We find that if they have trouble grasping basic concepts on the 3 in 1 machines, we can get a pretty good idea if they have the right stuff to be a machinist. It is a lot better than turning them loose on a 100K machine.
