Thanks Michael. I am heading there tomorrow cause the parts I have on hand don't seem to work the way Eddy's do. I really want a VERY flexible hose, hopefully similar to the one that came with my NSK pen style. I am thinking that I don't want to be changing tools on and off the hose for fear of getting dust or grit into an unattached hose and cause heck with the turbines. I am still doing my piercings in my shop where dust is everywhere!
