	Because of the long travel and the servo being on the right side, you need to offset the mill to the left by 9" (with X-Y extensions 12") and in by at least 2" from the Y Servo to inside of the front edge.. We place the mill on 2x6 sleepers at least 5' long. . We do this for a few reasons: Keeps the mill from piercing the liner. Distributes the weight of the mill better. Allows chips to fall out from under the machine. This center line shown lines up with the stringers below.

	After drilling the holes, inject as much silicone caulk as possible in them.

	Coat the threads with silicone. This lag bolt will go about 2 1/2" into the stringer below. Try to get the 4 mill bolts to line up with the stringer also.

	Securely tighten down the bolt. You will need 2 bolts to hold it down at about 5" from each end.

	For coolant we placed a 15 gallon tub under the drain.

	We used a bar to get the right cut markings

	Cut out and installed. We cut a matching hole in the tub lid and installed the coolant pump.
Now that we have the sleepers in we can put the mill close to where it will go, but don't bolt it down yet. You now have to cut your hole for the wires, at least 12" up so the wires angle down and the coolant can't run uphill. You can also go over the top with them. Now you fire up the mill and check the travel limits. Make sure you have room on both ends and the front then bolt it down with the lags. Get them in the stringers if you can. Now you can start on the front and doors. This photo shows how to cover the wires going out of the enclosure. Just use a piece of the rubber material left over.
	The 1/8" plexiglas can support it's own weight, but use the 1" x 1/8" flat aluminum to protect the edges. As you can see here on the left it is riveted to the outer angle and a piece of aluminum. use caulk on the 2 ends and bottom only. The center mount is just 2 pieces of 1" flat mounted to the top and bottom with the plexiglas in the middle The slider is a 18" drawer slider bolted to the top angle. The door is 24" wide with the double 1" aluminum all the way around. Bolt the other half of the slider to it. All the connections are 1/8" pop rivets x 1/2" length.
	This photo shows the door and center mount. The doors really work easy.

	This photo shows the doors together. The angles in the photo are from how the picture was taken. They are very square to each other.
