Chapter 27

Removing the Apron from the MI-1220 XL

Please have the manual at hand when working on the machine and when calling Smithy

Co. for assistance. The apron is removed with the leadscrew still installed in the apron.

This prevents the worm gear inside the apron from falling out off place.

Procedure:

1.

Remove the taper pin from the left end of the lead screw. This is a tapered pin and

must be driven out from the small end.

2.

Remove the 2 screws from the right support of the lead screw and remove the

support.

3.

Slide the tail stock off the machine.

4.

Remove the 2 screws from the fromt support of the crossfeed screw and slide the table

back away from the front support far enough to be able to get the 4 screws holding the

apron on.

5.

Remove the 4 screws that hold the apron to the carriage. The apron will drop down

far enough to allow the apron gears to disengage from the toothed rack on the front of

the machine and let the entire carriage to move freely left and right.

6.

The apron will not drop down far enough to come free from the carriage because of

the two taper pins that would go through the carriage inot the apron.

7.

Loosen the two carriage gib adjustment screws to allow easier removal of the carriage.

With the assistance of a helper, slide the carriage, table and apron assembly off the end

of the machine just enough to be able to remove the apron then put the carriage back

onto the machine.

8.

Tap the two taper pins up and out of the carriage to allow the apron to be reinstalled

without removing the carriage from the machine.

9.

To remove the leadscrew, turn the apron upside down and remove the cover. Pull the

leadscrew from the apron and watch the position of the worm gear so you will know how

to reinstall it properly. There is also a key inside the worm gear. Make sure the key is in

place when reinstalling the gear and screw shaft.

10.

Reverse the above procedure for assembly.
