Re: Helms 25 Centerboard restoration

That sure is purdy.
I believe Caleb is right insofar as the most economical way to approach this. Pulling the board and grinding it clean would be the place to start. Then having some material added by welding on to the most damaged sections and regrinding to shape. As long as most of the original thickness is present, the board should have sufficient strength to be repaired. Ospho or Naval Jelly treatment and the refairing with epoxy as mentioned would probably give you a number of years at much less cost. Btw I noted the estimate you sent for the new board; Fairing, coating, surfacing, paint and delivery were not included in the cost and could easily come to several hundred more dollars.
A quick calculation indicates that the board should weigh about 310 lbs +/- 20lbs, so it could be removed in the yard with use of a scissor jack and an extra hand or two. Pounding out the old pin will likely be a bit of a pain, but very doable.

Let me know what you think.
