Being a marine fabricator, I deal with it all the time. Really don't think it's going to be an issue, I guess I could slide some delrin shims between, I'll do that if/when the time arises. So, how far are they supposed to be?, I don't remember exactly but I think they are 22" on center, wouldnt be a big deal to hack them down and reweld, if that's what the experts think, I'm learning as I go,with a pond as small as mine (.165 ac) it's got to help no matter what, Thanks for everybody's input.
