These photos were taken on Thursday 6 July 2000, when Drew Devitt of Newway Bearings helped us replicate the air bearings in place on the Axtrusion Carriage. Click on the image for a much larger image. The steps indicated below are only the steps that we took photos for. They are not the complete listing of steps for replicating the bearings in place.
|Step 1: Drew cleaning the Axtrusion way||Step 2: the rough placement of the top bearings on the way||Step 3: The carriage is lower in place and the top bearings positioned correctly. Then a vacuum is drawn through the top bearings to hold them in place.|
|Step 4: Drew degreasing the surfaces of the bearing that the epoxy will bond to.||Step 5: Place side bearings in carriage||Step 6: The carriage (w/ side bearings in place) is lowered back on to the top bearings and the way. Fine adjustments are made in position of the side bearings within the carriage. Then a vacuum is drawn through the side bearings to secure them to the way.|
|Step 7: A piece of cardboard that is the correct thickness to set the air gap between the motor coil and magnet track is placed between the two.||Step 8: Our hero (me) lowers the motor coil down onto the cardboard space to set the correct air gap and place the carriage under the its actual loading condition||Step 9: Now a batch of epoxy is mixed up to hold the bearings in place|
|Step 10: Drew injects the epoxy into the side bearing pockets.||Roger continues to inject epoxy into the side pockets.||Drew inject epoxy into one of the top bearing pockets.|

The bearings can be locked in place on the way by drawing a vacuum through them. This ensures that they are accurately aligned with the way.
|The semi-fluid viscosity epoxy was used so that it would not make a huge mess when injected into the bearings and motor pockets.||Look at that cool epoxy on the carriage (subliminal message, buy Moglice buy Moglice... you are getting sleepy etc. etc.)||Drew posing with his way cool bearings|
