5 months ago, i repeat, 5 months ago i sent the us distr. for omas a ftn. pen for repair.it has been sent to me 4 times still leaking...this included a 2 month trip to italy
What pen did you send? What's the leaking problem?
I've had a leaking problem with with a couple of my very recent production Omas celluloid piston fillers. What happens is that when I carry them in my pockets, whether on their own or in a pen case, they dump a certain amount of ink into their cap. Odd thing is, when I store them in a one of my 12 or 24 pen cases they don't do that. And when I carry them in my coat pocket it still happens but not nearly as badly. And it's not nearly as bad in the winter. I finally figured that it had something to do with heat. Body heat to be specific. When I put the pens in my front pocket, they heat up a bit. When I have them in a case that's to big to be carried and it has to go in a briefcase or backpack, no heat, and no leaking.
I mentioned this to Jon Mottishaw at a pen show last year and he said the ink reservoirs on the newer piston fillers are so large that the problems associated with the air in the reservoir (expanding, pressure changes) can be exacerbated. So the problem can't really be repaired, just mitigated. It's a design flaw, not a manufacturing problem. My take on it is that I just can't carry these pens in my pocket. I'm not nuts about it but I can live with that.
