Re: Installed a helix mooring anchor last weekend...
Sean, there are also helical mixing "screws" used in industrial mixers. To mix up paints, foods, cement mortar type products, all sorts of things in huge quantities.
Most of that stuff is fabricated in stainless steel, so if you can find a local shop that fabricates stainless for large machine parts, for industrial customers, food service, etc. they may also be familiar with fabbing up "helixes". Except in the anchor, you just need the bottom disc of the helix, not a whole screw of it.
