I don't think I explained myself well. I used the heyco cord grip at .865" to 1.260". It must be just a hair to big. I have the next size down already, but the problem is the bushing for the large cordgrip has already been glued in, so it is either start the project over or find a fitting that can reduce the thread size of the existing bushing. I found something at Home Depot this afternoon that I think will work as long as my guess on the new thread size is right. I assumed 1" since the fitting is at home. I hope that is right and I hope that fixes it.
