This isn't actually a problem per se, though it may be and I just don'
know it yet. I have a Grob Bandsaw at work, it is a 24" vertical mode number NS24. On the front of this bandsaw at the lower right corner i a foot pedal. This foot pedal is all the way down and won't come bac up. I got to looking inside the "cabinet" on the bottom half of the sa that houses the motor and pulleys and this pedal is attached to rectangular bar that runs horizontal from front to the back of th machine, though not out the back. The bar has one pivot point, and a the end of the bar opposite the foot pedal is a vertical rod about 3/ diameter. It runs up through the top of the lower "cabinet". Also i this assembly, right behind where the pedal bar enters the front of th "cabinet" is a hydraulic shock absorber, I don't know that that is wha you actually would call it but that's exactly what is looks like, lik a strut off a car. It is attached at the bottom to the bar and at th top to a solid mounting point. So, it looks to me like when you step o the pedal that rod in the back moves up and down, going in and out o the roof of the cabinet, and the shock absorber is there for the retur to bring the pedal up. Hope you followed all of that. I have already determined that the shoc is no good, I disassembled this entire assembly to get the shock out an it doesn't move, it's seized. My questions before I go any deeper int fixing this would be:
- What does this thing do?
- Would it be of great benefit to fix it? (I have been using th machine for 6 months without it)
- Where can I buy parts? (I tried Grob and the machine is too old)
First off, this pedal is not for any type of blade speed adjust, I hav seen that before and this saw is not that type of saw, this one has ste pulleys for speed adjust. I was thinking maybe this is some type o brake to stop the blade when you shut the motor off? I am pretty sur that there may be pieces missing if that is the case, because I don' see any brake mechanism. Any help would be greatly appreciated
