Good folks of FC. Couple quick questions.
Just received my second hand qaroma and coil. Had a few blasts and so far I'm very impressed.
On receipt I gave it a good clean. There was a metal gauze/screen at the bottom of the ruby chamber, presumably to ensure the 3mm balls don't block the air holes.
Would rather not have any metal in airpath.
Is this as qaroma designed/supplied or has this been added?
If I remove, will the 3mm rubies block the air holes?
If so, how is this avoided? I did consider a layer of 4mm beads followed by the 3mm. Is this a good idea or will the larger beads work their way up the chamber to the top ?
Cheers
