One end of the large and the medium spreaders should be slit about an inch with a hack
saw or a jig saw, if available, as shown so that later, when telescoped together the clamp
can be slipped over the slits and tightened. An unslit end goes into a slit end.
Drill a 9/64 inch hole through the end of the largest section at the opposite end of the slit
end. This hole should be 1 1/2 inch from the end and will be used to insert a pinning
machine screw into the base plate where the section is U bolted.
