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 tank
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.......
