The Work Continues - Composting Toilet

Work is progressing nicely on the composting toilet. WAIT!!

 Perhaps I should discuss Why a composting toilet.  My future plans would have me staying on Wind Wager for extended periods of time.  A portable camp toilet really begins to smell quickly, even if emptied daily.  So, after much research I decided  a urine diverted composting toilet would be the way to go...Pun intended..  Now when I began looking at cost on manufactured toilets I was in sticker shock.  Ranging from $550 to $1300 to do your business seems a little crazy to me.  Plan B is to make my own, so here we go..

Make a cardboard mockup

Need 2 holding devices

I decided on a C-Head type shape and built the base and top portion out of 3/4" plywood.

I ripped some 2 by 6 in half to use to support the 4 points.

The measurements was to find center of the bucket because I will need that later.

I cut the top plywood to gain access to holding devices leaving a 1" rim.

  

I had to carve out clearance to remove bucket.

Fancy diverter eh!!

Ok,  so now I start working the mount for the poop stirrer...  details sorry.

Cut plywood section to cover back half of bucket and hinged to back 1" section of top

Mounted a PVC endcap to bottom on bucket

Made adapter to fit bottom of mud stirrer

Mounted mud stirrer with copper strap to hold on center

Seat is mounted to hinged plywood section

Now to cover the sides and so forth.  I used 3/16"" plywood  for coverings and nailed and glued to frame

Front drop down is there to fit Wind Wager's space

I stained at first with a Mahogany stain but painted white to help keep the small insides of the head appear little bigger

Made crank handle from Mahogany and a 3/8 socket driver.  Fits through hole onto stirrer.

I spent 5 days on Wind Wager this week and gave it a good test..  I LOVE IT?  No smell!  I do need to make a couple of changes.

1. Make front panel hinged to remove urine container.  A 1 gallon jug last 2 days.
2. Crank handle failed.  Develop a better mounting of 3/8 nut drive to wood.  The wood stripped out on 3rd use.

Well that's it for the DIY.  I will post on the 1st trip 2017 next.

Take Care,

Tom
