Thx guys

After a lot of private problems for my colleague Zytrahus

the block is almost ready (start in november/december 2002 I believe). We wanted to try foundry to do a different project than others people with milling machine (too easy), to learn new things (injection mold and wax mold)...
There were a lot of problems with copper foundry. There were 3 different "people who do copper casting" (I don't know the word for "mouliste") because they were too sure of their experience and say 'Yes, yes I can do it. No problem!" but they don't be able to produce a good primary product (>90% bad blocks) so a big lost of time with them

. Finally we found a better firm which give us satisfaction after several months of inactivity...
A good advice for you, keep out of copper casting with "thin design" it's really really hard to make it. People with good experience of "wax mold" are very very rare :shrug: . Bigger design is not a problem at all. Copper is a sh*t to cast, to mill..
It will be a nice block from Zytrahus style but not performing as well as a Cascade, not the same flow technics and not designed for that... ZytraBlock2 reloaded (

) will beat it

(without foundry this time lol )
Make a block for people is an interesting project but there are a lot of constraints behind that, Cathar know them
