Memory is a strange thing especially with the passage of time this project has taken. I guess some of it is too hard to bear so i must have blotted alot out, its only when i've returned to a part of the project and as is now the case, i've forgotten to take any note of the measurements or the methodology that i have had to sit down and figure it back out.
Not a problem as thats essentially what've been doing for the last 9..................(memory block...............err i mean) last couple of years. Now that i have settled on a design for a couple of storage pods to be fitted up under the foredeck on either side of the forecabin - one end going to the anchor locker but the other finishing two-thirds along the length of the v-berth i wanted a resolved-looking design which naturally included a curved end seeing as it wouldn't meet the new bulkhead the other end.
Problem was i couldn't remember how the hell i got 12mm ply to behave like spaghetti, so i took to my own blog using the search widget to find pics of the curved galley modules i made over two ye........... a little while back.
Turns out if anyones interested (i doubt it) in 12mm you need to cut a kerf 10mm deep at 5mm intervals, so with my table saws 2mm blade you get a 3mm gap between each kerf, fascinating isn't it ....not.
Also because of the angle of the forepeak i didn't want a ninety degree corner but a 120 degree one instead which meant making half a dozen 30 degree add-ons to bolt to the former i made two and a half y..........................recently.
I still have a heap of joinery i've made that needs to go back in which is nice as i don't have the ballache of making many more bits to get the insides upto muster. Another bit i had made a while ago then this weekend started playing with was the ornamental bulkhead that sits over the structural one to finish the anchor locker.
This - in the interests of weight is made up of 6mm ply and framed up with 18mm to take a hinged door so access is available, this will be either screwed in from behind or the front seeing as the insulation and subsequent liner will hide the attachment.
Just need to topcoat it in the spray shop and that can go in, another job off the list.....................

Still spent the weekend bolting in the first of many pieces now made forthe inside, namely the locker doors and ironmongery. Didn't go quite as planned even with each screw hole properly piloted and even some copper slip on the screws, i still managed to grind the heads off of a few of them.
What else? The keels. The keels - what can i say i'm still crazy after all these years to get them right, took the advice earlier given about 'crisping up' the trailing edge and did the same to the leading edge and the top of the trailing edge too.
To finish i gave the keels a quick coat of epoxy and pigmented it black to see the full horror of my fairing attempts from a few years ago and it is terrible but now know where to make the corrections, needless to say never get your boat gel-peeled!
I have a few days off as works slack (surprise surprise) so gonna push on insulating the forecabin and start fitting out the space.
Also nearly forgot, i have the anchor locker all done complete with foredeck reinforcing, a sub-assembly to take the forestay loads a bit better than the original that showed to be pulling slowly up through the foredeck, no really.
It looks quite '50's sci-fi but will spread the load better than the six 20mm penny washers that was the previous method. I found a bew way too of pulling glass round corners and that is to mount the piece you're glassing up on vertical plates inside the bag and then apply pressure, works a treat.

Its been a while, one thing and another has conspired to limit my resources for this project the last 12 months, that said i'm still pretty skint but what i want to get on with i have the materials for - things like ply, decorative veneer and epoxy.
The insides coming along but thats a closely guarded secret which i'll reveal at some point as i don't want to post too much before i get back to where it was before i destroyed the last iteration.
Having spent a good few days in the shed doing maintanance i realised how awful the keels profile were when lit from the one working light at the time, so made this the first order of business not before building myself a new table saw courtesy of ibuildit.ca and equipping the shop with a complete set of tools and machinery largely made up of old 110V kit and a few bits bought on ebay.
This way i'm completely independent of the day-to-day kit i previously had to keep removing from the van everytime i worked on the boat plus i'm not putting mileage on the tools i use to make a living with.
The profiling of the keels was always on the cards seeing as the gelplaner had all but iradicated any detail of that area of the hull so after sorting the trailing edge i thought it timely to consider the leading edge.
The original plan was to build up with fairing compound and shape but i know from experience putting the hull back together you end up chasing ghosts via the light and shadows cast. However while assessing what to do with three of the four flood lights in the shed dead that i saw an absolute howler on the port keels front edge.
Due in no small part to me piling on the kevlar and glass i had eventually lost the original fine profile, infact the shadow cast by the one working floodlight implied my fine naca profile replaced by an almost semi-circular shape instead.
This may seem excessive considering it is only a Centaur after all but they're slow enough already without putting the brakes on further with mis-shapen keels and seeing as the finer detail at the stubs top forward-most area was gone lead to the decision to sort it.
Cue hot-glue gun - bought for just four quid on ebay i can't recommend these enough for temporary or permanant bonding depending on application as this attached the ply to the boat with all checked before, during & after with the laser - another tool in the box thats proven its worth. Once made i glued and screwed mdf plates either side of the ply patterns so as to hold the profiles shape.
Once happy - and this is where the hot-glues properties come in - a sharp jerk of the plate and the whole assembly broke free from the hull with the glue on! So no clean up of the boat, happy days.
As is the case this was the easy bit, got there though using correx and then getting super itchy routing lap joints in the glass. All done over a couple of days so a good start back, just need to sand out the lumps in the glass and cut the profile before bonding to the hull.

Just getting my body clock round the right way having had a few weeks in New Zealand then i should be good to go again. In the meantime i think i have figured out google photos and have got all the albums sorted back in date order on my Google + page called 'collections' all accessible by clicking on 'Project Photo Album' in the right hand margin.
Highlight of the NZ trip was nerding out once more in Auckland, at the viaduct - this time around it was seeing two of the late Sir Peter Blake's Whitbread boats, Lion from the '85 / '86 race and Steinlager 2 from the '89 / '90 race although i couldn't get anywhere close to 'Big Red' as the gate to the pontoon where its parked was locked but still impressive to look at both nonetheless.
Lion New Zealand
Steinlager 2 'Big Red'.
Work and pictures of my project will resume shortly, at present its too cold for bonding so bear with me while the weather warms up. Have got on making a few interior bits but have decided to get things finished before posting the pictures
