I just found the note about composting toilets, I recently got a Sun Mar excel from a friend, it won't fit by an inch or so, I'll make a work alike look alike one from a 55 gal drum, and extra parts I got.

Hi,
Just read your post today. Don't know why, but I haven't been on the forum for a year.
If you still want to know about my composting toilet/head, I'll watch for your name.

If you have any pictures or details about your construction of your composting head, venting, etc. I would like to consider them, I plan to build one myself using 5 gal pails (20 liter), I was wondering if you did anything with urine collection and disposal. my e mail is jheld at ksu dot edu , thanks Jon
