I apologize for this silly, simple question. I see some folks use something that looks like a copper tubing thats crimped on the end and then bolted to the neck cavity. That seems like a smart idea, and I could suspend it from the ceiling and thus have easy access to the body while spraying in an upright position and be able to go around it 360 degrees. Went to Home Depot and Orchard Supply hardware looking for some crimped aluminum or copper tubing, but they look at me like I am a fool for asking. I cant imagine crimping the end myself - I dont have tools with that kind of force! Any help or suggestions would be appreciated.
