I have a coarse SS mesh (for strenght) covered with a thin fine-meshed alu. plate. ( for small particles) If I understand you right, I should replace this alu. part.. ---------------------------------------------------------------------------- Atle Aamodt ---------- > From: Lee C Kresge <nssdiver@ju*.co*> > To: aaamodt@on*.no* > Cc: techdiver@aquanaut.com; rebreather@nw*.co* > Subject: Re: Sodalime and aluminum > Date: 13. januar 1998 23:54 > > Yes, sort of.
