Hmmm, what's that noise? some kind of begging and bothering....
Progress is being made! Still only one shutter exists, but with a modification, and a mold plan has been drawn (the tube and the outer door are a bit finicky). Still no pricing, but a mold has been made for ANOTHER project, so in a way closer.
Excellent decision not to rush. Personally I have worked on some projects a looong time (real life interferring) and byt he end, shortcuts happen. It's just not right!
hang in there, soon we will have test castings...and who knows, you might even get to participate in a free evaluation...
