Smithy Midas 1220 LTD - Manual (Page 22)

Three-Jaw Chuck
1. Remove the three bolts behind the chuck that hold it to the spindle flange (Figure 5.2).
The chuck will come off. Don’t let it fall onto the ways. Placing a board between the chuck
and ways will protect the ways.
Place the machine on a strong, rigid table 40” long, 24” wide and 28” to 33” high. We
recommend you to bolt down the MI-1220 LTD machine using the holes in the base of
the bed or using the lifting handles as they held the machine to the shipping pallet.
Selecting a Location
There are several major considerations for selecting a location for your Smithy.
Operation is from the apron side, so allow at least 40” to 48” clearance in front of the
machine.
The machine should be on a 20-amp circuit, positioned as close as possible to the power
supply. Try not to use an extension cord. If you must use one, check with an electrician
about the proper size.
Provide ample working light over the operator’s shoulder.
Figure 5.3 Check along and across the bed to make sure it is level.
Place the machine on a solid foundation, concrete if possible. If you must put it on a
wood floor, make sure it is adequate. Brace it if necessary to prevent sagging or settling.
Make allowances at the back of the machine tool as at its end and above it for later
additions, attachments, and/or accessories. Provide clearance on the left end for bar
stock to be fed through the spindle. If you are considering placing more than one machine
in an area, allow enough floor space to feed long bar stock to each machine.
Notice
To check bench and bed level accuracies,
successively place level at A, B, C, D
(longitudinal positions) and E and F (transverse
positions). Bedways alignment in the longitudinal place
should be better than 0.0016/40”; alignment in the
traverse plane should be better than 0.0024/40”.
