installation of new eyebrows

[crazycarl]

i purchased new teak eyebrows from compac and i'm ready to install them.

i no longer have the original screws and i filled the original holes some years ago knowing the new eyebrows wouldn't line up with the existing holes.

before i do some exploratory drilling, i thought someone may have an idea as to how thick the side walls of the cabin are?

thanks in advance,  c.c.

Carl: The thickness is about 2 1/2 feet. Go ahead and use lag screws!!! 
I remember penetrating the glass about 1/8" when I reinstalled mine...I wasn't comfy going any further. But, my 23 has wood on the inside so if the screw poked through the glass, I never would have known it. I think it's thicker up there near the turn where the cabinside meets the top. Have fun...and report back, wouldja??

I've replaced the eyebrows on a 19 and a 27. The original screws were cut off to limit the penetration to about 1/4", which is enough to hold securely without punching through the interior trim. I used 4200 sealant, and put the outermost screws as close to the ends as possible (about 1/2" from the end). Countersink and fill holes with teak plugs, then varnish in place.

On the CP-19's that are XL's meaning a fiberglass cabin liner, even the shortest screws of 1/4 inch [below the head, actual threaded shank length] are dangerously close to popping through.

It has a cute little R/V red LED light with a shade and pull string that I found at a garage sale for a buck that I screwed onto the inside of the liner where one out of three 1/4" mounting screws popped out through the vertical wall just aft of the porthole ~!~!~! now that is close. I should have just glued the lamp up there. The wiring is hidden behind the liner.

And that my friends is why the 4 inch ports on XL's stick out over the deck's cat walk so far. They are not 'embedded' into a wood surround inside the cabin.

I have wondered why the eyebrows are not screwed on from the inside.  It would seem that the screws could be sealed with 4200 and it would save all the plugging problems.

To replace the eye brows and screw them from the inside means that the glued in place XL fiberglass cabin liner would need to be removed.

Believing that is not possible.

And anyway wouldn't we want the head of the screw to pull the eye brow onto the fiberglass cabin and not the screw/threads pulling the wood to the fiberglass?

I have a little problem with my port side eye brow where the standing rigging got under the eyebrow's end and loosened that last screw and eyebrow up as the mast was walked up. Was in too big a hurry and didn't watch what i was doing.

I dug out the wood cap and backed out the screw and Marine-Tex'ed under, around and into the hole, cleaned up the drip and then wedged with my Port-O-Power cylinder the eyebrow back onto the glass and re screwed that screw back in tight. A couple of days later ... no good popped back to where it was. About 3/16 of an inch off the cabin.

Will clean the area up and try again. Can't use a longer screw without penetrating the inside liner.
I don't really want a second hole and screw and plug installed again next to the present one. Maybe a fatter screw?

Anyway the XL liner looks like this inside. Bright and white.
