One of my scores this week is a 7" Emerson horizontal bandsaw. Anyone
heard of them?
Its big, fairly beefy, and appears one step up from the usual
Taiwanese import. Ive not cleaned all the spooge off it so havent
found out where it was made. I do see a lable on the leg that says
Reliance Electric under the spooge. Which is a bit odd......and it has
a GE motor on it.
The aluminum step pully on the gear box was flopping loose and
battered out of size, so I chucked it in a 4 jaw, indicated it in,
then bored it out to .750.
Removing the entire chuck and setting it aside, I then put in a 5C
collet and a piece of 1" aluminum stock and turned it to .752 and
over length by several inches.
I then stuck it in the freezer for an hour.
When it was cold, I placed the 4 jaw chuck in my hydraulic press, and
heated the bored pulley with a heat gun, then pressed in the 1"
aluminum stub. Then I put the chuck back on the lathe, parted off the
over length bit of stub, then drilled and bored it to .626 to fit the
gearbox shaft (which badly needed clean up with a file)
( I was surprised on how close the aluminum stub ran, before parting
it off after I reinstalled the chuck and pulley)
Since I dont have a keyway broach, or a boring bar small enough to
slot it on the shaper (making a note), I took a long setscrew, and
turned the end to fit snugly inside the gearbox shaft keyway.
Drilling the old setscrew hole through the new bushing and threading
it, then rolling it 90 degrees and drilling and tapping another
setscrew hole (which will get a brass tipped setscrew) completed the
repair of the pulley.
When I plugged in the saw yesterday...sparks flew and I found the
power cord had been broken and shorted at the entry to the motor
terminal cover, so after I install the repaired pulley here in a
little bit, Ill replace the wiring completely, add a second switch for
the coolant pump and tank , replace all the rotted coolant hose
using hose from my piles of Stuff..and see if this thing will actually
cut, and cut a straight line.
If this thing is good, I may have my
Dayton/Grizzly/Import/Rebadged/Generic 7" horizontal bandsaw
available for someone.
Unless anyone thinks it would be better than the Emerson..in which
case..Ill sell off the Emerson. (but Ill keep the coolant pump and
Though..there is a nice old Kalamazoo horizontal sitting in a corner
of a clients shop thats not been used for many years I might be able
to trade em out of.......
