Coil winding in lathe

[Hemi]

yeah I'm with Brian on this one, I too don't think you'd need to split the PVC pipe in order to release the spring coil......... As the PVC is naturally a smooth surface so. and the spring itself could be release if "that" tightly wound, to release it by twisting the spring lightly against its coiling.. would expand it to leave go of the PVC pipe.....
