TEMPLATE KIT

The purpose of the TEMPLATE KIT is to permit cutting of elliptical and
obround holes. The manner of accomplishing this job involves dragging the
torch barrel against a template which is made 11/16" (18 mm) larger on the
radius than the cut-out desired (when using standard US machine torches).
The TEMPLATE KIT consists of a master layout template (aluminum sheet),
which is used to locate the bolt holes and center on the actual template which
should be made from 1/8" (3 mm) masonite or similar material.
A full-size drawing of the shape to be cut, should be made showing a center
point, then add 11/16" (18 mm) to the radius. (Because the torch body drags
against the template, adding one-half the diameter of the torch to the drawing
will put the center of the torch tip in the right position.)
MAKING THE TEMPLATE
Lay the aluminum master layout template on the masonite board. Transfer
the holes from the master by tracing with a pencil or use a quick-drying spray
paint. Next, position the oversized drawing, so that the center point is directly
over the center on the template and the shape is located symmetrically be-
tween the 'leg holes' (see sketch Page 17, number 8. Trace [or spray] the
outline onto the template.)
Next, drill the holes in the template. Then, cut-out the outside circle (outside
of the template) and the shape to be cut (on the inside).
MOUNTING THE TEMPLATE
The four CIR-9031 spacer legs should be screwed into the ring gear. (Remove
existing 2" (50 mm) legs.) The template is then placed on these legs and the
2" (50 mm) legs, or 5" (127 mm) legs, when using the recommended CON-
1040 leg and foot assemblies) are screwed - through the template - into the
CIR-9031 spacer legs, which clamp the template under and parallel to the
ring gear. Insert four round head screws (see sketch Page 17, number 12)
through the template - into the alignment bars (see sketch Page 17, number 7.)
SET UP
Place the rod [see sketch Page 17 number 5 in the base post on the carriage.
Slip the tensioning assembly (see sketch Page 17, number 6) on the rod.
Install machine torch in torchholder - make sure torch is straight up-and-down
in both planes. Adjust tensioning assembly so that torch maintains firm contact
with template when carriage is rotated. Connect hoses. Place machine on
work - locate feet and lock in position.
STARTING THE CUT
Lock tensioning assembly so that the torch tip is over scrap area, piece - or
start the cut in starting hole. When preheat is complete start motor (carriage
travel), release tensioning assembly and let it gradually swing to template -
(this action 'feathers' the start into the cut.)
