We have a Westsail 32 here in Annapolis that just refit with bronze chainplates. Southbound Rigging
http://www.voyageundersail.com/ Call them and ask for Mike.
They use a waterjet cutter and it sounded pretty reasonable.
I can shoot you pics also. It is bronze chainplate to Collage deadeyes and Dynex Dux rope rigging. We termed it the "Wireless Westsail"
It is Bronze chainplate and Titanium mast tangs, the Dux took 125 lbs. off the rig......:-)
