Thanks for this well detailed repair story.
Although my WB (122) has the outside pins, your sawing-operation gives a good sight of the inner of the WB.
Greetings Barend

So I got the board out. As previously mentioned, I couldn't rotate the board far enough down-wards to draw it out of the slot forwards, since the back end of the board came into contact with the top of the casing before the front end was low enough to pull out uinderneath the trailer crossbeam. The answer was to remove the crossbeam! I was a bit nervous to do this, but looked at and thought - well it's just a couple of steel tubes and a u-bolt.
I suppoerted the front of the boat with jacks, used a sharpie to mark the crossbeam and the frame of the trailer to show where it needed to go back, and got to it.
It came off fairly easily - and the board was easy to slip out forawrds after that. The weight of the boat deforms the trailer slightly and the crossbeam was holding that in place, so once I got the beam off, the trailer moved about 6mm. On replacing the crossbeam afterwards, a bit of persuasion with the rubber mallet while inserting the u-bolt did the trick.
So now I have the board out and the trailer re-constructed, it's time to break out the grinder (and goggles, proper respirator, gloves, long-sleeved garment and masking tape to seal the gloves to the sleeves - yes, I have ground grp before, lol!)

If the mods are watching, would you like me to write this up as an article? Once I have gotten the board back in and Jeny hasn?t sunk, of course!

« Last post by RogerH on August 19, 2021, 09:05:32 PM »This was ?crunch time? Would I be able to drive the pin out? Drascombes have a groove round either end of the pin a little way from the end, to help retain it athwartships ? if this were the case with the Winkle Brig, I might need to exert a bit more force that possible in such a confined space. As it was, no shoulder on the pin and it came out very easily.
I went back underneath and gingerly began to back off on the jack supporting the board, but it?s quite light at that end ? no need to worry ? and I lowered the board by hand, anticipating I would be able to lower the forward end to the ground and then slide it out underneath the trailer.
This is where things went a little awry!
As the forward end of the board went down, the aft end went up and came into contact with the top of the casing. The trailer crossbeam stopped me from getting the board far enough forward to pivot it further, so it?s not coming out that way!
The solution I can see is to support the front of the boat and remove the crossbeam with the forward rollers from the trailer. The boat will be well supported at the aft end and unable to topple. That way I?ll have a clear space to draw the board out forwards.
T seems a bit drastic to start dismantling the trailer, but I can?t see any other way. However, some of you may have done the same thing and found a better solution ? anyone got a solution to dropping the board out of the boat while on the trailer?

« Last post by RogerH on August 19, 2021, 09:03:53 PM »Well it?s taken me a couple of days but I got the board out ? well, almost (see later)
I cut another access hatch this time in the side of the saloon berth ? giving direct access to the board retaining pin. This hatch was far more difficult to cut as I couldn?t get any kind of saw into the small space between the hole and the floor (and the hole and the aft end of the Vee berth) to cut. I got the jigsaw in from 9 o?clock to 3 o?clock but after that it was chain drilling and a Chinese rasp.
I was then able to get my power file into the hole and dig around for the pin. A bit of guesstimation ended up nice and accurate and I exposed the inboard side of the pin at my first try! Chuffed.
Further measuring and guessing bore equally satisfying fruit and I got the outboard end of the pin exposed in quick time.
I went back outside and supported the board at the pin end ? I have no idea how much it weighs and I didn?t want it dropping out of the casing wioth the pin partially removed, potentially deforming the pivot hole in the board or the holes in the casing. I also made register marks on the board and hull so I would be able to line it up to re-mount it.

Even better, the pin is retained by glass patches over the ends of it, so removal of those patches will be (relatively) easy and I'll be able to expose the pin.
Driving it out might be an issue - I intend to support the weight of the board from underneath the boat and drive the pin out from the side. I'll need to cut a further access hole on the seat-front, but it's looking promising.The inboard side of the retaining pin is visible as a glassed-over lump on the inboard of the casing - I need to remove the foam on the outboard side to check it's the same - I see no reason why it wouldn't be.
Photos will show what I mean, I hope!

« Last post by RogerH on August 17, 2021, 04:15:49 PM »Once again for the benefit of anyone following the post, I?ve managed to answer at least one f my queries.
The bottom edge of the board is somewhere between 12? and 13? from the centreline. Allowing for the fact that they are angled off vertical I estimate the top edge could be 2? - 4? inboard of that, so between 11? and 8? from the centreline.
The inboard side of the saloon seat is about 6? from the centreline at the approximate location of the pin. This means I?ll have somewhere between 5? and 2? clearance with which to work between the board casing and the seat front
Depending on how the pin is retained, 5? or a bit less could be enough - if it?s glassed over either end like a Drascombe. So the current plan is to cut a round access hatch over the area and probe through the foam to find the top of the board casing. With luck that?ll tell me what size of cutout I need to make.
Fingers crossed!
