Great...

Thanks Morne and Xair.

I've found it surprisingly difficult to find much info and/or vids about making your own pipes - single or double walled.

I've entered various permutations of single walled, double walled, RC Turbine etc etc and about all I get coming up in RCU and RCG threads is people mentioning them, but not actually posting any build info. I've Googled the same key words, and tried in YouTube, but nada - not a lot comes up.

Maybe I'm holding my tongue wrong? LoL
