A comment I've seen on 'other' web pages seems apt here.

Topsides Topcoat
The temperatures are still cold but to move things on a bit I needed to stop the wind disturbing all the dust in the rafters and elsewhere in the shed. The solution was to buy some cheap foam and stuff it into the top of both roller doors. To save some money (I’m such a scunge!) I also purloined my son’s pool noodle and stuffed that in as well. Pool noodles are exactly the right fit for the gap I had but Clark Rubber and all other such places where these are available during summer had none in stock hence the foam. It all worked much better than I had expected and was able to get the two final Topside top coats on this weekend.
I forgot to mention that I had attempted the topsides earlier and was very happy with the Off White Brightsides I’d chosen. Great finish - much better than the Black on the bottom. Unfortunately, the second coat was ruined with the dust! I had to find a solution so had to fix the roller door issue which is done and in addition I wore one of those throw away Zytek suits and also put our backpack sprayer to good use and wet the floor down before doing anything. The great thing is it has all worked!
Unfortunately, my masking tape work was a bit remiss and some white has run onto the epoxy surface of the Transom but this will sand off OK - no harm done.
Now I have to decide if it’s worth redoing the Black. The problem with it was not so much the dust but the brush marks. It appears, after some experiments with the Off White, it has gone on too thick and didn’t get a chance to level out and has run in a couple of places. I had originally comes to terms with it but after the success of the topsides I’m rethinking it. I’m only going to get this one chance with the boat upside down to get the job done properly. I need to rationalise the extra work to sand it back and redo it for the second time. I guess it’s one of the vagaries of being an amateur.
You will notice that I have left an area at the Sheer for a different colour. My thinking at the moment is for a colour that will not be too stark but subtle enough to highlight the line of the Sheer. I’m thinking a light grey with a tiny touch of green in it. I cannot describe it exactly as it sounds awful but I have picture of a larger vessel with it and it’s impressive. The Gunwale Guard is NG Rosewood and with another run of it, albeit half to three quarter the size, on the lower side of the Sheer stripe I’m thinking that it should look OK. I will leave this until after the interior is complete and we’re into the tiddly bit stage as I may need to adjust its width when everything is together. I’m thinking it’s the one thing that should set everything else off and if I get it wrong it will look awful so …some patience on my behalf with this bit. In the meantime I will have to experiment with some paint mixing to get the colour I’m after.

Huh?
I don't quite understand what has happened but my posts have all gone astray somewhere. As ever it will inevitably mean an error on my behalf. I could have sworn I posted a large note with maximum number of pics.
Oh well, I'll try again.

Some Bits and Pieces
I decided to redo the Bottom (what the hell). It is better than before so it’s complete and another pic below just in case (not that you can see any difference). I really think the problem with the black was the age of the paint. I had it from my last build which was completed in 2004 (see the pic).

I have been working on the Centreboard Case in an effort to finish the construction part of it. To that end I have made the Centreboard Pin Covers, nothing spectacular but time consuming nonetheless. Using a large plug cutter I cut out an area in the centre and filled it with a 50/50 graphite epoxy mix with the intention to inset the Pin ends there. I shall seal it with a rubber gasket. See the pics – I haven’t cut the Pin insets yet.

While all this is going on and in those very short moments when the temperature was 15 degrees or above I set about reinforcing the Centreboard Case sides with glass (the insides were done prior to assembly). It also provided me the opportunity to try the peel ply I bought that haven’t used yet. Was supposed to go with it on the hull but chickened out. However, I’m now wanting to use it on the interior to save time (I hope). Anyway, it went OK and didn’t have to add any more epoxy after it had gone off. My learnings are this…….
· Beware any puckers in the cloth as they fill up with resin
· Might be worthwhile ironing it if the size is small enough
· Getting it on takes some patience
· Attack any deformities with a nice sharp scraper after peeling while the epoxy is still a little green. It comes up a treat.

I have also completed the internal cheek pieces to the sanding and painting stage. Refer post #103. I have since cut the stick into 4 pieces, more epoxy coats and shaped them. I will dry fit them to the CB Case and epoxy coat the holes ready for final installation. I’m thinking to paint the CB Case sides first and use RH bronze screws from the outside to provide that finishing touch and make them all the more accessible when the need arises to replace the cheek pieces as and when required.

CB Case Cheek Pieces
Now I’m back in business I shall carry on from where I thought I’d left off!
These are pics of the Cheek Pieces being dry fit. I have since sanded them back ready for paint.

I have also have been working on the modification of my old boat cradles in readiness for the anticipated turn over. The pics show them finished and ready except for the chocks that will fill the turn of the bilge spaces.

Note that at the back of any furniture store you can get these great huge heavy duty plastic bags that once were used to protect Big arm chairs. Slit down the seams you get these great boat covers!!
Work commitments are hotting up with the working weeks to be spent away so not much will get done over the next month or so.

Tomcat Turnover
Well things have certainly slowed down with working away during the week with maybe one day to get anything done whilst I’m home.
BUT…….I have turned her over! Smooth as glass with nary a thing to report about going wrong. All on me very own without a finger being lifted by others. You can tell I’m chuffed! So, where to start the story.
First of all I built a full frame around the boat using some framing timber and by cutting up Mould 4 used the chipboard to make the corners that took the weight of the boat during the rolling process. Super Cheap Auto had a special on chain blocks (half price! couldn’t have come at a better moment). I also purloined a couple of tow ropes from my emergency car kit to complete the package.
The frame was constructed by attaching the bottom two athwartships lengths to the Moulds at the height of the Strongback. This ensured clearance all round. I then added verticals so that their height just cleared the Keel. Two more athwartships lengths completed the box frame with the added chipboard pieces on the corners that were to be used to roll the whole thing over onto her topsides, then onto her Keel. Additional strengthening pieces were included to take the wracking forces I thought may be there. To ensure everything stayed put on the Keel side I added two T-pieces that protruded thru the CB Slot and were attached to the turning frame outside and the Moulds inside.
The sequence went something like this……
· Attach the lifting ropes to the opposite side of the radiused corners
· Hoist away until she becomes light on her feet then gently push sideways to keep the topsides under the lift point
· When happy lower away to gently rest her on her topsides
· Relocate the lifting ropes to the opposite side and lower away whilst gently pushing her in the right direction so she rolls thru the radiused corner and begins her descent.
· At strategic points stop lowering and push or pull her so that she ends up in your position of choice. (I say all this because I was short on space and was rewarded with the knowledge that she was going to be light).
· Finally once on an even keel I moved the lifting ropes once more so that I could lift her straight up and roll the Strongback underneath.
· Place the Hull supports in their strategic location and lower away.
· Dismantle the framing and there she is
· Next remove the moulds after ensuring you have transferred any critical lines from the Moulds to Hull
· Last but not least, make sure you have plenty of pics of your process for prosperity and have a well deserved drink or 2 (or 3 or whatever) of something that will help you remember the great day!
· I hope the pics tell the story

Sorry...ran out of space for more pics. See some more below. From here its back to the drudgery of sanding and filling prior to sheathing on the inside.

Nice job. Looks like the turning was well planned and went without a hitch.

Laurie,
It looks really great. There must be a great deal of satisfaction even at this stage of your project. I hope you toasted your achievement with an equally great drop.
John
