RE: catalina27-talk: Re-bedding stantions

[Phil Agur]

Hi Mike,   5200 is going to the dark side, never on a fiberglass boat. I went to change out my cockpit speakers just last week and found another bad application for 5200 by my dealer. I my actually destroy the aft lazarette covers before I’m done.   Boat Life Caulk of Sikaflex would be good. The factory uses silicone, which makes a good gasket but is a poor adhesive so I don’t care for it as much. It would be prefect for a no stress items like speakers or instruments that you know will need updating. After 11 years we’ve only seen one leak, so silicone isn’t all that bad in general.   BTW, the goal here is to use caulk to build a custom gasket no thinner anywhere than say a 1/16 of an inch. Bob mentioned finger tight until it sets but I’d go a step further by dry fitting and identifying the actual contact points. At these points I’d position the end of some tooth picks to hold up the item up off the deck a 1/16. You can use tape outside the joint area to keep them positioned.   Now when you do hand tight there will still be 1/16 of an inch of caulk at the thinnest spots. Caulk can be stretched more than 50% of it’s thickness before breaking the seal but if it’s paper thin or squeezed to nothing then the first time the pulpit is jarred the seal is broken at the thin spots.   Once the caulk is set pull out the tooth picks, fill the pinholes, and tighten.   Phil Agur                    s/v Wing Tip Commodore,             Call Sign WCW3485 IC27/270A                   MMSI 366901790 www.catalina27.org      Vessel Doc# 1039809 -----Original Message----- From: catalina27-talk@memberclicks.com [mailto:catalina27-talk@memberclicks.com] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, August 26, 2006 6:02 AM To: catalina27-talk@memberclicks.com Subject: catalina27-talk: Re-bedding stantions   Hi list, I'm getting ready to put my pullprit and all deck stantions back on the boat after a long and painfull deck re-core, anyway is 5200 above/below what I want for re-bedding? or is there something better.
