The reason I went with it is because there are plenty of other repairs I have to do in the coming weeks, such as, fixing a delaminating portion of the deck, on which I plan on using nothing but the West System; therefore I just bit the bullet and bought everything I need for the further repairs as well. <br /><br />During my rudder repair process I did some testing with the 3M resin and hardener sold at big box stores and I can say it works fine for some minor rudder repairs. The price is about a third of the West System epoxy. <br />However, there are some considerations to have, I can honestly say, the West System is a lot easier to use due to the mixing ratios and the pumps which make it really a foul proof method, the other resin has mixing limitations depending on the amounts needed for the repairs, I will not go into details (you can find them online) but you get the idea.<br /><br />Good luck with your repairs!!!!<br /><br />Willy.Anonymoushttps://www.blogger.com/profile/08362039639564184951noreply@blogger.comtag:blogger.com,1999:blog-6387010524904144756.post-21796773561546775162012-12-15T13:22:29.995-05:002012-12-15T13:22:29.995-05:00Thanks for your fast answer

I guess you work on one side first and place some kind of backing material until the fix sets in and then it would be easier to do the other side. Did you use West System fillers?<br />I will attempt repairing it next January. Will take pictures and post them<br />Again, thanks<br />Anonymoushttps://www.blogger.com/profile/04945955873799711041noreply@blogger.comtag:blogger.com,1999:blog-6387010524904144756.post-81565318285175620792012-12-14T20:07:00.023-05:002012-12-14T20:07:00.023-05:00Hi Jim, thanks for looking !!!
Your idea sounds go...Hi Jim, thanks for looking !!!<br />Your idea sounds good, that's basically how they build rudders for bigger boats so, if it works in a larger scale it should in your repair as well. Just make sure everything is water tight to prevent rust on the wires.<br />Another thing you can do is taper down the edges around the missing "chunk", fill the void with foam and glass at least two layers of woven mat on top of the foam and into the tapered edge. That should also give you a strong repair.<br />Whichever way you go, I hope it turns out good and you can be back sailing soon !!!<br /><br />Good Luck and please come back to report on your experience.<br /><br />Willy.Anonymoushttps://www.blogger.com/profile/08362039639564184951noreply@blogger.comtag:blogger.com,1999:blog-6387010524904144756.post-13052394153672329562012-12-14T15:27:53.875-05:002012-12-14T15:27:53.875-05:00Hi Willy!

As you can guess the ...Hi CJ, thanks for looking !!<br />As you can guess the weakest part of the rudder is where you found the crack on yours and where mine broke. After seeing how the original rudder was build, I don't know I want to spend the time and effort to rebuild/fix the one with the crack and probably deteriorated plywood core. The reason you are not finding any wood on the lower part is because there's very little plywood on the blade portion of the rudder, most of it is some kind of filler, not sure what it is, it's white, very brittle and heavier than epoxy, the rudder is wrapped with, what appears to be, just one layer of Chopped Strand Mat glass which is not the best choice for the task. Actually woven mat is stronger due to the length of the fibers and, if you add a second layer in diagonal it will be much stronger than two, even three layers of the chopped strand mat.<br />As for as re-glassing, I think it will add some good strength to it, but, if the core is gone, you will be only relying on the shell to give you all the strength you need. I'm not an engineer but I don't think it will last long. That's why I built mine with a good plywood core (1/2") plus one more strip on each side and two layers of woven glass mat on the outside. I do not want the rudder to break again. <br />Hope this helps. Let me know if you have any questions and please stay tuned for the completion of my project, almost done....<br /><br />Willy.Anonymoushttps://www.blogger.com/profile/08362039639564184951noreply@blogger.comtag:blogger.com,1999:blog-6387010524904144756.post-87270900603981361422012-11-14T18:58:06.520-05:002012-11-14T18:58:06.520-05:00Hi Guillermo!

My new to me 1974 Catalina 22 has a kickup rudder, but I found a blade style rudder on a boat that was about to be demolished. I have nted a crack in the rudder in way of the lower pintle and drilled some holes and found a moist core that appears to be wood. I will grind down the cracks and then reglas and epoxy to build it back up. I was curious what is the core material for the lower part of the rudder. Any ideas? I drilled into the lower rudder and did not find any wood.<br /><br />Thanks again and good luck!<br /><br />CJ<br />Covington, LA<br />s/k 3198CJnoreply@blogger.com
