Hi Guys I thought you might be interested to see my treadle chicken feeder that I built from the plans that Gallo del Cielo posted here https://www.backyardchickens.com/a/building-a-treadle-chicken-feeder the detailed plans were a great help to me though I have used some different materials and wood that I had on hand.
I have it mounted on two permapine square posts a bit under 100mm x 100mm or 4inch x 4inch

I have made some changes, one I used aluminium rectangular tubing 10mm x 20mm or 3/8inch x 3/4inch and I was worried about the chickens feeding from the sides so I put some side panels on but in hindsight I should have made them wider to cover part of the treadle as they can still access the feed without standing on the treadle. I also didn’t include the divider for two types of feed. I was not able to access the linkage bolts so I used 1/4inch x 1 ½ inch what we call gutter bolts http://www.lbsbuyersguide.co.uk/polythene-film/sheeting-film-accessories/gutter-bolts-100.html they come with a square flat nut, I also used flat steel (zink plated) washers and nyloc nuts http://en.wikipedia.org/wiki/Nyloc_nut Below is a pic of one of the side panels.

Below is the feeder with the side panels on.

Here it is below with some temporary boards to extend the side panels and I find that they are now standing on the held open treadle to feed. Later when they are trained and the side panels are proven a good thing I will make them a permanent fixture. I tried the bricks in front of the treadle to create a level platform from the ground to the treadle but it is debatable if I need them. Time will tell but it stops them from scratching dirt under the treadle

Below is a pic of one of the aluminium rectangular tubes note the steel tube (bush) I have glued in with epoxy glue so that it is a bit more resilient to wear. I made these from tubing from 100mm x 8mm (4inch x 5/16inch) Dyna bolts http://www.mitre10.com.au/Hardware-and-Building/Nails-and-Screws/product/22886// I was able to get 4 bushes from one Dyna bolt. I drilled a 5/16inch hole in the aluminium tubing and with a round file enlarged it slightly. As the bushes have a longitudinal split in them I spread them slightly so that they were a snug fit in the aluminium and then tried a 1/4inch bolt to see if it fitted. If it wouldn’t go in I then filed a little more out of the aluminium. I then glued the bushes in place with araldite a two pack epoxy super adhesive that cures overnight. http://www.selleys.com.au/trade/specialist-products/epoxy-adhesives-fillers/araldite-super-strength/
Once cured I filed the sides reasonably flat. I cleaned any residue of glue out of the bush with a round file and not a 1/4 inch drill bit as I found when I tried that the drill bit caught in the split in the bush and spun it free of the not fully cured glue and I had to glue it again.

I may later have to add a little weight under the treadle to slow the closing of the cover. I see Gallo del Cielo has his taking one second to close which sounds nice mine is a bit faster but the cover is not too heavy for them.
To keep it open while I train them I have a length of cord tied to one arm of the cover going up through an steel eye above (a pulley would be nice) then to the outside with a weight on it. When I want it open I let the weight hang and when I want it closed I put the weight on the roof so that it is not pulling. I will use it like that till after Christmas and then I will start to train them to use the treadle.
