wow that got me going Larry! prior to my retirement, i worked in a wind tunnel and i just happend to be working on building a device that i used on my dredge to pulsate water into a fliudbed . and i asked one of the aerospace/wind tunnel engs. about my porting for this device and that is exactly the port design he gave me. i later removed this device from my dredge because of a poor location on my dredge! you can imagine what would happen if i did get a load of gold/blacksand in my fluidbed chamber............HIHO Silver!
