Over the years have collected a lot of various glass lens elements. Now seems to be the ideal time to put together some of these elements and create a few usable lenses... hopefully a Petzval optic, but any final lens with interesting Bokeh would greatly satisfy me. Where to start fabricating the barrels? PVC plumbing tubing or ? Published cross sections of lenses are a good place to start. Not looking to put together a "sharp" optic, just one with interesting Bokeh. Looking for any tips on physically constructing some of these optics. I have a good collection of lens barrels, spacers, adapters, etc... of course none of them are matches to each other. Using a hot glue gun seems to be a very necessary tool. So far I have discovered that slowly using a chop saw to cut PVC pipe makes for getting very accurately cut rings of PVC pipe, if the final cut of the last 1/8" of the pipe is made by hand.
thanks in advance
