It'll be good if someone would make kathy0577 understand, what we really require here. A true GVG alternative, not some workaround, more in the line of this
:
(a short self-standing j-hook pipe with a bubble
and a chamber (!) made of thick glass) At a price of $ 15,00-20,00.
Intezam apparently is a bit rusty in regard to our
guangdong angruish and our PR0C transactionist skill level is also poor
- we also lack the required
sunshine dust :x . We hope, that one day kathy0577, or anyone with 8+ guangdong
agony skill level would also pay attention to the healthstone and how these can be sourced or manufactured in PR0C. All one needs is quality 1200 F silicium carbide powder with some added black glass powder. Make a thin batter of these. Now you need
polyethylene foam (such as those used in hepa filters or some aquarium filters) with the right pore size (small) and ppi (60). The foam is soaked within the silicium carbide batter and it should penetrate everywhere (inside). These foam sheets are then hanged to dry. Once dry, they are (carefully) put into an oven and now the polyethylene foam is burned (sintered) completely at a very high temperature, leaving only the silicium carbide which is further heated until fully hardened and the added glass powder ads some glossy sheen to it. Now, the silicium carbide sheet is ready and can be cut into small discs, which are then further hand ground until the have the desired taper and form. Alternative: the polyethylene foam can be pre-shaped into (oversize) small discs prior to coating/drying/sintering/hardening process - but needs to be touched up by hand.
If such a j-hook is sold separately from the top piece and healthstone, who can say anything patent wise? Also if you look at VG company, themselves just came up with a near clone of the magic flight launch box and they call it a "generic product". If you are aquaintance with kathy0577, well, maybe stefan555
can communicate that...:thumb_up:
Apologies & cheers, Sir + :thumb_up:
