That is very impressive, and it shows a high level of creative tinkering. Thank you for taking the time to share your projects with us.
Thank you, this is kind of tinkering is a compensation for my work - where I have to work with lenses but most times are not allowed to tinker with them :-)
Only need to add newer projects to my webpage, like my three Petzval projection lenses that I converted to Canon EF:

There is some risk involved. But I changed the filter many times with no problem up to now, especially the first months I sometimes chnaged the filter a lot. And I donīt work very carefull, on location, the camera probably on the backpack, or on my lap. Need ~one minute for a filter change.
But for sure, I know this would be nothing for most photographers. But with a gasket for the filters it would be much more easy with nearly no risk but dust.
