After reading your message I realized that I must have remembered just
enough info about that article to be dangerous. Sorry. So I finally
found the original article. It is in Ceramics Monthly March 1990, and
was a suggestion contributed by Ira Merrill from Wrangell, Alaska. It
reads as follows:
"It's easy to make your own sieves if you have access to a wood
burning stove or some other hot, flat surface. Simply cut PVC pipe(6 to
10 inches in diameter) into 2-1/2 inch (or more) lengths, then cut
squares of stainless steel or bronze screening with dimensions slightly
larger than the PVC pipe. Lay a piece of aluminum foil on the wood
stove (or alternative hot surface); spray with a cooking oil (such as
position a square of screen on the foil; and press the PVC pipe down
onto the screen until the plastic starts to curl at the bottom edge.
Remove the pipe (screen will be attached) and place it on a piece of
cold steel; press down (hard) until it cools. Use tin snips to trim the
outside screen edges, then sand the burrs off and you've got a new
Don't know if it would work with the bucket. If you try it, let
me know. Sam

Sam: I tried the melting sieve cloth into plastic on woodburning stove
just like the article said. I may be a klutz--perfectly possible-- but I
had bad luck with it, leaving aside the process smelled bad. I piped up
ONLY becaue epoxy worked /works much mroe easily for me....

Dear all I get my sieves from a local potter's supply store (my opposition).
As far as I can make out he takes the 12" polyethyline pipe and puts the
sieve material and then takes either a slightly larger diameter pipe or heats
up another piece of the same diameter pipe and slips it over the material
and the original piece of pipe. He makes terrific sieves and they last for ages.
Hope this helps Ralph in the "Friendly City"
