me too, that seems to be the trickiest part about the whole setup. i'll share everything when it comes in, should be by the end of the week.
Screwgreen, you might have won this little contest to find working plans. http://www.astrosafari.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=21471 only a pic but i bet with my grandpa;s brain and mine working together we could get it done then ill try a write up. wont be for a few days though. EDIT: didn't see that Dark had already bought the book. Ill let him do the write up cause i agree mounting the diaphragm will be the hardest part. Ill be waiting...........
it came in the mail yesterday. i'll look at it when i get a chance and will definitely have it scanned in my computer by the weekend to share with everyone.
i read through it real quick and it looks pretty cool. the diaphragms are easy and the tuning is just changed by the length of the funnel or the 3/4" or 1" pipe before the funnel. he included a message in the pamphlet that said to email him to get more info about tuning and vids to help with the build.
Heck yeah. I couldve used these so bad. Me and my friend road up on some people gettin it on in a little dirt road in there car.lol
