Maybe you forgot to seek?

Note also, taht "f.write tlf.read" will slurp the whole file into mem
before writing it out again.  This may or may not be a problem, depending
on the size of your file.

Taking this together you might want to do this:

# reset file position of the open Tempfile
tlf.seek 0

# copy in chunks
open(@lg,'a') do |f|
  while ( data = tlf.read 1024 )
    f.write data
  end
end
