homemade 70mm loader

Ok so I bought a cheap SS pan with a glass lid from the store, broke the glass so only the metal rim was used (the rim had a rubber ring around it so I thought it would be good for preventing leaks) then I took a black pail (like a small plastic garbage can) who's bottom just fit inside the ring, cut off the wall of the pail and put the bottom if the pail inside the ring. I then glued that with some super glue followed by industrial sealer glue.
Then I cut a hole in the pail bottom to fit the JOBO, measured how deep it went then drilled holes in the side and bottom if the JOBO (but at the far edges) so light won't go in but chemicals can drain in and out.
Then I glued the JOBO inside the pail lid same glue process making sure the holes in the side were as close to the edge of the pail lid as possible (for optimum draining). Then it wasn't draining to my satisfaction so I took a candle, turned the lid upside down, and melted wax inside until I had it perfectly level with the drain holes. (Don't do this if you want to process C-41 or E-6 as higher temps may melt the wax).
Then I took gaffers tape and covered the outside of the pail lid just in case since the black plastic wasn't super thick.
That's it really.
I usually process at night. Once I did during the day with this and ended up with some light streaks at the edge images so it's not perfect. If I did it again I would have used a Paterson tank instead. I'll probably add light baffles to the holes to prevent that daytime stray light. But it's not so bad just doing it at night is fine with me.
The hardest part is processing, it takes exactly 2L if chemistry, hand inversion is a pain and I'm strong but still hurts my wrists by the end.
I hope I didn't miss anything... Oh to be sure the lid doesn't come off I tape the lid with gaffers tape around the edges each time before processing since the weight of the liquid when I invert it is heavy, then when I'm done I just take that off and throw it away.
The only thing that leaks is the JOBO lid, but I've never had a good JOBO that's why I canibalized it for the experiment but now wish I used a Paterson...
