>epoxy to fill holes.   Garolite  is an epoxy laminate sold by McMaster- 
>Carr in various sizes.
>  Over the course of a year I had to use a dremel tool with a flex drive

>damaging useful areas.  At first I balked at taking out the pivot slots but 
>early in the summer I realized they were also bulging inward with bad 
>cement behind them.  The pivot slots had to be reinforced from behind at 
>home and carefully evaluated for any severe permanent damage before I 
>decided to fix them.  I actually considered making my own copies out of 
>wood and fibreglass, but just reinforced the original ones.

>bad laminate and in most cases,  dry cement would fall out.  I figured I

>are extra pieces of  fibreglass on the back sides of  some of the larger 
>panels which have been wetted out by injecting thickened epoxy through a 
>DUNCAN DONUTS straw attached to a West System syringe.  Only DD straws work 
>for this job!  The extra fibreglass attaches to the tie layer and the extra 
>injected epoxy to help create a strong bond.  After pouring sand there will 
>be much room for more thickened epoxy until the voids are filled.

>I am now up to sanding down the walls with fairing sticks, using regular 
>80grit and 100grit paper.  In some places i will be able to use my dremel 
>tool with a sanding drum but since the drum is only 3/4" wide at most, its 
>not an efficient way to get most of the job done.  Dremels tend to leave 
>tracks anyway.  But in the narrow sections of the aft taper on the trunk i 
>will need the dremel tool.

>board with new a custom SS bail which holds my pennant.  I opted for this 
>bail because the pennant now takes up less space as it connects to the 
>board.  The bail is a flat piece of SS I had laying around which is about 
>1/ 1/4 " wide and only about 1/8" thick.
>  I also bolted a  Harken double sheave to the top of my cap.  The sheaves 
>are in line and separated by enough space to re create the mechanical 
>advantage of the original design. The Harken bullet sheaves, I believe they 
>are called, are complimented by two new sheaves on the board, also with new 
>SS mounts.  I tested  the sheaves on the system before I installed it.

>more of my restoration!

>R22 Arhives for future boaters who may have a similar issue. There will be 
>pictures, and illustrations, but if you think about the angle one needs to 
>see into the CB trunk, a picture is not really going to show the details of
