My Archaeological Sieve
Posted October 20, 2012 - 12:12 PM
This year's mix of ashes was questionable enough (a lot of old painted stuff and who knows what's in the paint) that I just dumped it with the clay fill so it will get buried and covered with topsoil and then grass.
Anyway, burning scrap lumber creates another problem...nails and screws and old hinges. The kind of things that damage tires. I've been trying to find a good way to separate those from the ashes.
Mrs. Rev also likes to get the lumps and rocks out of the compost and topsoil when she's potting plants.
Finally, I'm always looking for something to do with all of those fence boards I have stacked behind the shed, and like carpentry.
So I was watching a video on the internet and these guys were digging up a Bronze Age village in Britain and shovelling the dirt into a sieve. I realized it was what I wanted.
They showed a close-up of an old knife or something and you could see the wire and part of the frame. I figured out the basic construction from that. I looked up some videos on the internet and discovered the pivot portion is usually just bolts riding on wood. That seemed a little shabby to me, so when I went to buy bolts I picked up a couple of bushings as well.
I built mine a bit bigger because I don't have a power tool for cutting wire mesh, and I'm basically lazy, so I decided the sieve should be the same size as the mesh I had. The increased size made it a little more wobbly than I liked, so I added a cross member. I didn't see any with handles in any of the videos, but the boards I was using were long enough, so I cut those in with a jigsaw.
The basic construction is easy: Cut the boards to build a box the size you want. Cut in the handles. Cut an inch off the bottom of each board. Build the box. Stretch your wire mesh over it. Attach the one inch pieces back to the boards with screws to hold the mesh in place.
Tack the legs on. Drill a hole the for the bushing and whack it into place. Untack the legs and put a bolt (I oiled it first) though the bushing with washers on each end. Double nut the bolt so it isn't too tight.
Use a plane or sandpaper to break the edges on the handles.
I took me a couple of hours, including the trip to Princess Auto, and has given us about three hours of use so far.
Here's some pics:

Nice job Rev. Looks like you turned excess stuff into something usable. What will you do with all the nails.
I keep them until I have a load going to the scrap metal place or one of BILs has a load I can throw stuff in.

"In December, Wisconsin’s environmental agency fined John Menard, owner of the 200-store Menard’s home improvement chain, $1.7 million for burning CCA scraps to heat the company’s lumber production facility. Menard was caught carting the ash from that facility to his home, where his disposed of it with the family trash.
In Minnesota, 22 cows were killed when a farmer spread fireplace ashes from CCA-treated wood in the field where they were grazing.
Polaski’s review cites two incidents, reported in 1988 and 1990 newspaper articles, of people harmed by using treated wood for fuel. In both cases, the people developed neurological problems, numbness in the arms and legs, loss of hair, skin rashes and gastrointestinal upsets.
“Burning any of the wood in a fireplace or outside is a bad thought, and presents a clear exposure route to toxic chemicals that should absolutely be avoided,” the EPA’s Rotenberg said."

CCA is not real good to burn, and poses some long term ill effects.

Truckloads go to the landfill every day. Is that better? And if one were to take them to a Hazardous Waste Center, how do they dispose of it?
Since I don't have John Menards money, I wonder how it would be profitable to Prosecute/Persecute me?
Not trying to be a wise guy, just curious as to how it should be handled?
Rev I like your sifter!

In regards to disposing of CCA treated wood, most likely your solid waste hauler would like to see it in the landfill. Is that better than burning it ? Well, I am not sure, but that is how it is regarded here.
The EPA thinks landfilling it is better than burning it, as the Arsenic binds to other molecules, and gets passed around our environment , wildlife, and children. Here is their take on it.
Having been a carpentry contractor for a couple decades, I have used tons ( literally) of that wood, and have never had any ill effects from it, but am always leery of it's properties.

And I do burn small amounts of treated lumber in an out door pit, but the ashes and debres are bagged or boxed and taken to the land fill.

T think I want one of those in our bedroom LOL. Though , I think this thread still needs the vid of the upside-down trailer drag...
Why not I'll get flaimed again, oh well. This was before the 38" blade, and I needed a way to clear rock and catus, and break in the newly rebuilt 18 hp briggs. Be kind....
