Ron I usually don't leave it in the press more than a few hours for good measure with the Bolduc glue. But always at least 2. I'm not in a hurry. Only overnignt if it's the last thing we do that day.

No noticeable leaks, and no failures (yet). I figure the caulk sealed it airtight, while the hose clamp pressed the lining into the threads for the needed grip. Oh yea. Why are some of you leaving the clamps on overnight? Is it the glue you're using? After an hour, or even as little as a half hour with Titebond, you couldn't get the rib off without destroying it. Just curious. Ron N -------------- next part -------------- An HTML attachment was scrubbed... URL: https://www.moypiano.com/ptg/pianotech.php/attachments/20080927/9c8c7142/attachment.html
