I have a Hegner scroll saw that I've used off and on since I bought it used a few years ago. Lately I'm noticing a whole lot of vibration from the machine. On closer inspection I found that the top and bottom arms are not aligned properly. They are not parallel. Even if the blade is properly seated in the top and bottom clamps, the blade itself is not perpendicular to the plate -- it is diagonal. The top arm is sitting just to the right. I can use my finger to bend it to where it "wants" to be to be aligned with the bottom arm, but I can't find any adjustment on the underside of the machine to try. I tried adjusting the two tension spring screws towards the back of the arms, but these are not really for repositioning the arms.
I read through the manual, which didn't say anything about left to right alignment of the arms. The Hegner has a plate with a notch cut out of it in the shape of a "T". In the manual, the photos show the blade sitting just at the joint in the "T". On my saw, the blade sits in the right fork of the "T". This seems to be a separate problem from the arm alignment, because when I push the top arm into alignment, the blade still does not sit where it should. It seems like the blade is supposed to be able to move back to front and not hit the plate, but on my machine it is almost touching the plate, and occasionally does during use.
I'm not sure what to do as I live in Los Angeles and lost my paperwork for the machine many years ago. I am stuck fiddling with it or mailing it to Delaware for service.
Any Hegner owners out there with advice? I've got some photos below.
