BUILDING
FRAME - Epoxy glued and bolted the building frame together. Glued
in some additional cross members and chipboard gussets to stop
twisting and racking.
Intend to level frame up by adding some 50mm high 4x2 legs.
This will give a reasonable working height of approximately one
metre from the ground to the top of the keel. |

22 May 2000 |
DECK MOULDS - Started cutting and polishing the foredeck mould,
got around a 1/4 of it done before getting back into the building
frame.
BUILDING FRAME - Squared the frame up and screwed chipboard
gussets into the ends to stop it moving. Have also coach bolted
the ends to really stop it moving. Cut out a couple of "ladder
rungs" for the middle to stop bowing. Will hopefully dry
fit everything tonight and then epoxy glue it in place. Have
borrowed some clamps, spirit levels, and a builders dumpy (theodolite)
level to line up the frames, hopefully, on the weekend. Many
thanks to Bob Vernon for the tools. |

DECK MOULDS - Sanded back entire mould surface working down
from 120 grit paper, to 400, than 600 grit paper. Test polised
a small area, and left rest to complete curing over night.
BUILDING
FRAME - Picked up some 250 x 50 mm kiln dried Pine for the hull
building frame. Have tack nailed it together, and will screw
and glue it together tomorrow when we can level it in its final
position in the garage. Far end is 1200mm apart (to stop mould
rocking) and 400 mm at small end to keep it under the mould and
out of the way. Total length of frame around 4300mm, or about
50mm longer than the final hull.
TIP OF THE DAY - When picking the timber choose something
really straight, with enough grunt to stop the frame bending
as this will affect the rocker of the final hull. Never trust
your garage floor, the beams in this picture are 1 inch off the
floor at the camera end. Legs will be fitted to ensure the frame
is level in the garage and the frame will not be moved again
until the hull mould is complete. |

DECK
MOULDS - Sanded back Duratec using an 80 grit paper, found a
few low areas (see picture) that needed a bit more of a build
up. Tried a small 80mm mohair roller and it definitely gives
a much better surface to sand back against. Spot painted foredeck
and left to dry.
TIP OF THE DAY - Sanding with a pair of the latext glove we
when painting etc stops the finger tips wearing out quite so
much. |

Friday Night - Not a time for working on the boat |
|
18 May 2000 |
DECK MOULDS - Test sanded a small area in the morning before
going to work, looks like it will sand back and polish up really
well as the coating is now really good.
HULL MOULD - Collected another 15 odd sheets of Chipboard
for building the hull mould. This stuff is HEAVY, had to chuck
some more air in the trailer tires and jack the drawbar up to
get the trailer off the car at home. Also brought 2 more sheets
of plywood for sheaving the hull mould. This time have a 3mm
Hoop Pine instead of Meranti which should take the bending a
lot better.
No more work on the boat tonight as we are writing another
article for Sailing New Zealand. |

17 May 2000 |
DECK MOULDS - Sanded back the Duratec primer with 120 grit dry
paper. Found quite a few areas where the brush strokes were a
bit hairy to work with. Ended up giving it the once over and
applying another layer of Duratec to form a complete surface
to work against. |
|
16 May 2000 |
DECK MOULDS - Got two pretty heavy layers of Duratec sanding
primer on the foredeck and side-deck moulds. Applied the Duratec
by brush and roller (until the roller spat the dummy and fell
to bits). Ideally Duratec should be sprayed on as it achieves
a smoother finish quickly, but without the spray gear a brush
was the next best. Will have a bit of sanding to get out the
brush marks, but a quick test showed that it should sand nicely.
The moulds are now a battleship grey colour, sort of reminds
me of my last job...
Part of our reason to work on the deck moulds first is to
make all our mistakes on the less sensitive areas before we start
dealing with the hull. We might try and borrow some spray gear
when it comes time to Duratec the hull mould. |

15 May 2000 |
DECK MOULDS - After lots of longboarding yesterday, and another
coat of bog, and sanding tonight the decks are looking pretty
close to being ready. Next step is for coating with a sanding
primer, and then sanding back, cutting and polishing. Hope to
stick on some Duratec (sanding primer) tonight if I can only
figure out how to open the tin...
Planning for the Hull Mould is progressing, Unitec have the
frame plans and are re-formatting them for CNC cutting. We have
another supply of chipboard coming this week so hopefully should
get the hull frames cut ready for assembly this weekend.
Decided that the garage was a little lacking in light, 2 x
150 watt bulbs were replaced with 4 sets of twin 5ft flouro tubes.
The light difference is amazing, with some irrigation we could
grow a pretty effective cash crop after the project is finished.
Thanks to Javelin sailor and electrician John Wilson Electrical
for the wiring efforts. |

 DECK
MOULDS - Made up a couple of ice cream containers of Polyester
Resin and Dera Lite fairing powder to make a bog to smooth out
the mould surfaces. Used a slightly higher 3-4% MEKP catalyst
ratio to allow for the powder and get the bog hard enough for
sanding later in the afternoon.
2 hours later - Started sanding off the Bog using a Sureform
Rasp, seems to cut it back pretty quickly. |

13 May 2000 |
DECK
MOULDS - Primed the timber mould surfaces with a Styrene/Cobalt
mixture to give greater adhesion to the polyester resin. Layed
a single layer of 450g Chopped Strand Matt on the Foredeck and
Sidedeck moulds with Polyester Resin. This soaked up a lot of
resin, probably around 6 litres for 5 square metres of deck area.
As for the rest of the day, in the early afternoon we were
showing a prospective Javelin Owner a few of the excellent second
hand boats we have in Auckland ($3500 - $4500 range). At evening
went out for dinner, and found that I brought my first Javelin
of one of the guests uncles, small world... |
|
12 May 2000 |
Purchased
lots of materials (resins, powders, cloth, solvents) and a few
consumables. Most of this will be enough for a couple of hulls.
Many thanks to Grant Beck, and Chris Timms and Adhesive
Technologies for their excellent advice on materials. |
|
9 May 2000 |
Rang around and found some good sources of material for the
moulds and hull laminate, will pick some stuff up today.
No progress on the boats tonight, went to the International
Comedy Festival instead. If you Aussies think Steve Irwin (the
most well known Australian in the world) is funny, you want to
see a Pom taking the piss out of him on stage... |

FOREDECK
MOULD - Removed around 400 staples, and 50 screws from the foredeck
mould. The Epoxy glue set well, apart from a couple of small
areas where the ply sprung back a bit. Bogged all screw and staples
holes, glued down the "sprung" areas. Mould should
be ready to sand tonight, and hopefully glass and bog later in
the week when I can get the materials.
SIDEDECK
MOULD - Re-bogged some areas where the glue attaching the Mast
section has sagged. This mould should also be ready for glassing
and bogging this week.
Pricing out some Polyester Resin, and chop mat for sheaving
the mould surfaces.Trying to decide on the curvature in the false
floor. The aim is to have enough curvature to get water out of
the boat quickly, but not too much so that you are climbing the
floor during roll tacks. Currently looking at around a 5 degrees
rise from the centre on each side. |

7 May 2000 |
FOREDECK MOULD - Planed and faired up stringers. Tortured
some 4mm ply over the stringer mould, this was glued down with
epoxy glue, and held while drying with some grunty 2 inch screws
and lots of staples.
NOTE: Photo updates will appear later
this week, someone else has borrowed the Digital Camera. |

6 May 2000 |
FOREDECK MOULD - Epiglue still a bit rubbery, so left the
mould alone for a while.
SIDEDECK MOULD - Started building a sidedeck mould, used a
piece of broken 63mm mast tube to get a fair curve along the
inside edge where the top of the deck transitions into the vertical
section. Mould was made using 6 x 16mm chipboard frames built
into a solid box. These had a 63mm hole bored in them to align
the mast section. Frames were then cut to final shape. The top
and inside surfaces of the mould were bevelled to fit around
the tube, and the gaps were filled with some spare HT9000 resin
and bog powder.
Did a bit more shopping in the morning, more screws, some
heavy duty staples, and picked up some old stools from the Navy
Yacht Club for "Saw Horses". |
|
5 May 2000 |
FOREDECK MOULD - Got the final stringers on the mould after a
visit to the Navy sailing club for a beer. Epiglued (Epoxy glue)
all the foredeck stringers down. |

FOREDECK
MOULD - Not much progress last night, had a friend round for
dinner, so worked on increasing my sailing weight with some Pizza
for Wellingtons windy conditions.
Got the final stringers onto the mould. Have borrowed a second
12V cordless drill, keyless chuck, 20 torque settings, life is
sweet again, I love power tools... |
|
3 May 2000 |
FOREDECK MOULD - Cut 9 frames
out of 16mm Chipboard, and screwed them to another sheet of chipboard
as a base. Have attached about 1/2 the stringers so far. Stringers
are 15mm square Redwood, and will be spaced appoximately 70-100mm
apart across the mould. Stringers are screwed in place for now,
but will be eased off and glued down after they have been fitted.
TIP OF THE DAY: Make sure you have lots of cordless drills.
Changing drill bits, countersink bits and screwdriver bits with
one drill is a complete waste of time. New drills arriving soon.
Purchased 4 sheets of 3.6mm Meranti plywood for sheaving the
moulds. Might not quite be enough, but the supplier is within
visual distance of home. Running out of screws fast. |

2 May 2000 |
Bit more work on the new Class Rules Ballot with Dave. Have a
final draft and will be sending it off for voting soon.
FORE-DECK MOULD - Managed to grab 1/2 hour to cutout paper templates
for the fore-deck mould. All set for doing some woodwork (at
long last) tomorrow night if the ballot gets sent out ok. |
|
1 May 2000 |
After a complete anhilation at indoor cricket with the work team
(100 vs 279) and a late return home only had time to work on
the upcoming ballot for the changes to the Javelin Class rules. |
