That's how I did it Carsten, except I looked for a bucket. In hindsight there
is more variety in plant pots. I fibreglassed around a portion of the bucket
& built it up to the right shape, but an easier way to do it would be to buy 2
buckets / pots, one to fit inside the other to form a mold. Cut the bottoms off the
Buckets & seal them to a base. Then pour in resin & throw some fibreglass in
for strength. Form the edges later.

Of course it won't increase power, since that comes from your motor. If you just put a shroud around your existing prop, you will be disappointed, and a shroud that doesn't do the job is overpriced unless it's free! Key ingredients for success:
