Hobart 6614 Bandsaw for Meat Cutting
When I installed the bandsaw and hooked up the three-phase power I ran it just long enough to demonstrate that it worked. But that wasn’t long enough to discover what we found out this week when we went to do our dry run in our new butcher shop.
After we did the wash down and sanitization we did a much longer run run of the bandsaw and discovered that the blade is not tracking properly. Instead it is slipping forward on the pulley and biting into the metal with it’s teeth. That’s not good for the blade and not good for the pulley. In fact it was spitting micro fine particles of steel all over the nice stainless steel of the saw, the walls, the floor, me, etc…
I check the manual but it has nothing about this problem or how to align the blade. I tried YouTube videos and Googled intensely. I called the sales guy and he didn’t know although he had a few things to try. Unfortunately none of those worked and the tech he talked with didn’t have any ideas.
Disassembling the saw such that nothing was touching the blade except the pulleys proved that the problem had to be either the blade itself or the pulleys. My bet was the alignment of the top pulley was off but given that this is a brand new machine I hesitated to start hacking it without talking with with someone who might know for sure. $7,000 is $7,000 and I decided I could wait a little before taking it apart further.
After a little calling, phone tag and messaging I finally reached that right person, David at Hobart, and he said that while he had never seen this happen he thought the three alignment bolts on top of the shaft for the upper pulley might need adjusting. He said they take only a tiny movement, perhaps a quarter to a half turn. Unfortunately these bolts are not labeled in the manual and he couldn’t describe where they were – it was one of those very rare things that just doesn’t come up much.
So, I’m going to tell you this secret information just incase your meat saw ever goes out of alignment and starts eating bandsaw blades! Hush-hush, top secret – tell everyone! :)
Alignment Bolts for Upper Pulley Shaft
When I got off the phone with David at the cottage I hiked on down the mountain to the butcher shop. After some poking around I figured out which three bolts and reasoned out, correctly the first time(!) which two of the three to adjust. The odds were in my favor.
David’s suggestion was to use a 4′ level to bring the two pulley’s in line but the housing of the pulley’s made that difficult so I just tried it by eye a quarter turn at a time and hand spinning the pulleys – with the power disconnected of course! This worked like a charm and after 3/4 of a turn on the left most bolt and half a turn on the middle bolt the blade was happily tracking in the middle of the pulley.
Yeah for David at Hobart!
So, if you ever have your Hobart go out of alignment and it starts spitting carbon steel at you now you’ll know how to fix the problem.
May your pulleys ever be in alignment…
