Our pool is several, well, many years old and so is the diving board. The base finally cracked and needs replaced. It is so old the bolts and nuts have rusted together. We are having a terrible time just removing the base. I believe it can be replaced with a La Mesa dive stand and matches the jig perfectly. Problem is the protruding jig bolts are so rusted. My assumption is, though, the jig is in the concrete and it ain't coming out... is this correct? My father-in-law has suggested welding new bolts to the jig as this should be as strong as the original. I assume only other option is to cut out concrete, insert new jig and pour new concrete? Anyone have experience or thoughts on this issue? I know a lot of people are staying away from diving boards these days, but we love ours and would like to save it!
