[pure-silver] Re: bad vibrations

don't have that model but on an L1200 the fan is in the head. The fan is mounted on a rubber block to absorb vibrations. There is a transit screw which needs removing from the fan and reduces vibration dramatically. Don't know if there is something similar on your enlarger but if there are tubes then it sounds like fan is not mounted in the head. In which case, is the enlarger mounted on a solid floor or is it standing on boards. If its on boards then try stamping on floor to see if it causes vibration because if it does then it could be you moving about that causes the problem.


The air pump is on the floor. It may not actually be a fan per se, but just a thing that sucks air out of the head. The enlarger is standing on a concrete floor.

The ducts vibrate quite a lot, and so does the head. I have never noticed this causing problems in the prints before, but until now, I only used the 4x5 mask. It becomes a lot more obvious the larger the mask is, for some reason. I think this may be because the pump sucks air across the surface of the glass.
