hegner multimax 2 issues and questions

[BubblySoup]

Hello there,

I am new to the whole scroll saw world, got a used hegner but heck I have just been having issues so far even before working on my first project !

I have been adding some light oil as per the manual recommendations on the base of the upper and lower arm but here are my issues.

Initially, it seem to be quite noisy and kind of vibrating as soon as some tension is put on the blade.
I took off the moving arms, to see if there was some things missing (I did see a small piece of the edge of the thread from the C arm falling when i unscrewed it.. I guess old age) and I am wondering if maybe I over tightened them when putting them back... how tights should they be ?

I then changed the blade to a new one to try to have the best material to try it out with and heck, the piece that links the motor to the lower arm broke...
how can that even be ? (piece 21 on the hegner 14 parts drawing)

Tension wise, I put 3/4 of a turn after the slack point and the top screw holding the blade holder doesn't touch it (to prevent blade flying) as the manual recommend

I feel like I did something I obviously shouldn't have done because the guy I brought it from swear it ran smooth and wonderful when he used it (even with passion in his voice... but on the other hand, he didn't knew where to lubricate it).

Other question... when you look at the top of your hegner is your blade aligned with the open line on the metal base ?

I did contact AM but I am waiting for an answer... I can take pictures if need be... any advices welcome !

The plastic connector arm was probably already cracked and failing as was mine. That caused excessive vibration, then once it completely broke and was replaced, the saw smoothed up considerably. From what I can tell, the connector is the one piece that is most likely to break on old Hegners. I'm guessing the plastic chemically breaks down over time (like dry rot).

That's good to know, did you replace it including the bearings or just the connector per say? (price difference, $30 to $50)

Interestingly, I was having a similar issue. I have an AWFS18, from Axminster in the UK. This machine, as far as I can tell is almost an exact clone of the Hegner. It was just the bearings that were the problem for me, as the 'link' part is made of solid metal. just wondered if you could purchase the part intended for the AWFS18, and then you wont have any issues with breakage in the future? Not sure if Its available outside the UK though?

Seems odd that a machine which Is made predominantly of cast iron uses a part which is evidently put under a lot of pressure, that is made out of plastic... and it sounds like the breakage is not an isolated incident.

The bearings are pressed or molded in on the Multimax 22 part. The bearings come with the connector, so I just replaced that one part. The good thing about the Hegner is that it is not complicated, so these kinds of repairs are pretty straight forward.

The one concern I would have is that if the prior owner used this saw a lot, and did not oil the pivot points, there could be excessive wear there. I oil mine before each use.

I agree with Randy...keep it oiled..both of my saws have zirt fittings...not sure all Hegners came this way or not.

I am curious what model Hegners do you own, how old are they, and did you by

them new? I have never seen a Hegner scroll saw with zirt fitting. My five

year old Multimax 22-V has bushings at the arm pivot points. It sounds like

your saws have unsealed greaseable bearings.
