The body of the mill is connected to the base by four through bolts accessed by removing the rear belt guard and the ventilation grills in the base. However you will also need to remove the two drive belts (easy job) and of course the knee elevating screw. The nut for the elevating screw is fastened with three cap head bolts easily accessed, but once you remove it there is nothing to stop the whole knee and cross slide assembly from sliding off the bottom of the column when you lift the body from the base. There are some knee locking bolts but I would not rely on these holding since they are only designed to take out the "play" whilst machining. One other thing to be aware of is that these mills are inherently top heavy and if you are moving them by road they need to be very securely roped to stop them falling over. The machine weighs aprox 500 Kg with most of this in the main body and very little in the base, so little will be gained from a weight point of view from splitting the machine although you can reduce the height required which is obviously your question. If I were to move one of these I would leave it in one piece, secure it to a large pallet with ratchet straps and stick it on a pallet carrier with tail lift, it costs a little more but saves a lot of hassle.

If I had to move that I'd lay it on it's back on a pallet.

Chances are if you don't it will be on it's side or front anyway at the first corner.

Also, putting it on it's back on a pallet will cause any coolant in the reservoir in the base to pour out, potentially all over the main motor, which would not be pretty. Rigging straps can keep it stable on a trailer while upright. Needs to be a class 3 trailer hitch on the vehicle, as the machine is very heavy. Mine was injured by the seller when it fell off the substandard trailer which collapsed under it. Note that fixing the machine in its present state is not a small amount of work, depending on your level of skill and available tools, hoisting capabilities, etc… Which is why repair is still underway. Good luck, E

There are three 3 phase motors on a Harrison: The main spindle motor which is in the base, the very hard to get hold of power feed motor and the suds pump.

If you lay it on its back you will break the back cover as it only fibre glass and the base is not very wide so it will probably be unstable and end up leaning on the end of the table causing damage. The lifting point is in the over arm and there are tie down points in the base designed to help keep it upright when it is moved.
