Good cast iron won't bend; it's kind of brittle, actually. When the foundry delivered CB's to us you wouldn't believe the way they treated them; they just dumped them out on the concrete, and we never had one bend or break. Measure the thickness of the CB (should be under 7/8" if I remember correctly, then make a wood spacer the same width and stick it up in the trunk. Good luck!

Hi all,
I've had my M-17 on the hard for about 2 weeks now. I had the pox so I did the 4 coats of epoxy (interlux) on the entire hull and the keel and trunk are fine. I decided, since I could, to pull the centerboard, get it blasted and coat it with epoxy (only 3 coats) and 2 coats of bottom paint.
Now the board will not go back in.
Here's the interesting part: It looks like it has a warp in it. The starboard side is concave and the port side convex...minutely. (I did not look at it closely when I removed it) I did not think that cast could bend, and I hung the board the whole time I was painting it, not leaning or on it's side. It did not even rub coming out.
The pin end went in fine, but the tang end will not go in at all. I'm going to sand my painting work off a layer at a time to see if that will work.
My question is: Have you ever heard of cast iron warping? Has this ever happened to anyone before?
Thanks,
Michael Ray
