On the original I did smoothshade them. Just I didnt save the original...

I would like to thank all the participants for assisting me in this matter. Your help has been ivaluable. I now have a working pipe. Thank you all for your cooperation. I will not forget this...

Turns out the last bit didnt work because I messed up. But I managed to fix it. And now my pipe works just fine! Thanks everyone!
