I obtained these plans from another engineer in our American division. I've never built fully in wood so I'll be asking questions as I go. The frames and keel were lasered out by SLEC who did an excellent job.
The keel and hull frames are lite ply and the chines and planking are medium grade balsa as specified on the plan notes.
The frames as delivered are on another thread the build will be posted here.
Initial keel and frames pieced together.

I screwed some blocks onto the board to keep all square and tacked them all together using aliphatic resin wood glue.

It's a slow start I'm finding the temperature in my workshop slows the glue going off, my little fan heater warms the place up eventually.Shark boat Img_2048
After a bit of planing and sanding I'll be having a crafty plank starting at the keel.

Planking starts 1/2" by 1/8" the plan states 3/4" but I can't get them I've got medium grade but I think soft would have been better to go round the curves.
Shark boat Img_2049
I've put a false piece in to space out from the keel so I can shape it down to fit the curve, I've got the art of putting my little heater on while I do the washing up Embarassed so my sheds warm and my glue sets and grabs nicely.

Swab, I heat my workshop with a little 600 watt convector. I have put it on a timeswitch so it comes on an hour or so before I expect to start modelling. It also goes off before lunch so I don't forget to switch it off Rolling Eyes

The model is coming along nicely.

Added a few more planks after teaching myself how to bend them without breaking them.
Shark boat Img_2050
I'm wondering if I should have started at the deck and worked down Neutral
I've got both cellulose sanding sealer and Z poxy finishing resin what do you think I should use for the outer hull? i'm fairly sure I'll resin the inner I've not got any cloth to glass the outer hull.
I've packed up for the night and not took photos but the inside planking looks chippendale quality smooth and needs no sanding but the outer hull levels is as rough as a bears backside and needs quite a bit of rubbing down.

If you are not going to use glass cloth then I would use Zpoxy. Balsa is always subject to 'dings' unless you protect it, and sanding sealer doesn't really give enough protection. My Pilot boat has balsa sides and bottoms and I am trying to decide whether to use Zpoxy or aircraft tissue and EzeKote. The latter is easier to use as its water soluble until cured. I have some Zpoxy, but not very confident using it.

I've just found a bottle of EZE Kote i bought ages ago for this project I'm going to use that with some fibreglass cloth for the outer hull. I'll use a thin coat of sanding sealer to prepare the outer sand it down and glass coat it I want this to last and I'm the worst helmsman ever.
But I'll tidy my bench first orders are orders!

Initial sanding I've got some small gaps to fill but I've not had to shift too much meat.Shark boat Img_2051
Shark boat Img_2052
I've just ordered my prop shaft the props already here the plans stipulate a motor & gearbox but I'm thinking just straight coupling it to the shaft.
There's a bit of trimming to be done to the planking to bring it to deck level but hamfist snapped the deck supports and I need to replace them to give me a level to trim to.
I'm to photography what Johnny Rotten is to the Pope.

I can't see much wrong with that planking. 2thumbsup 2thumbsup 2thumbsup
If you can avoid a gearbox I would as they tend to be noisy. If you really need to reduce the revs a belt and pulley system is quieter.

I've not done much tonight I've cleaned up and vacuumed up a serious amount of dust and generally tidied up all the offcuts and shavings cluttering up.
Shark boat Img_2053[/url]
I had a bit of time left and mixed up a bit of Z poxy and coated the inside of the bow, I've been a bit liberal in the fore part as the planks had a bit more abuse and bending to fit so I think it needs an extra coat, I may add some fibreglass cloth to the inside to help it further.
I've also replaced the starboard deck support that's snapped in the photo.

Bit of progress because I missed a night owing to a grouse a famous grouse in fact!

Battery tray and fore deck.

rudder tube
that's a 5m pirat m rudder shaft in a 5.1mm i.d. tube I've got the tube and locknut supplied but it's 8mm diameter through a 9mm keel made of 3 laminates of 3mm ply i don't want any more doublers i can grease and seal the top of the tube it rotates easily with no drag so I'm going with this.
EZE Kote tomorrow as I don't fancy a 12 hour columbo marathon!

I've EZE Koted and glass clothed the outer hull and I've left it to dry before I rub it down and re-coat it there's some rubbing strakes i need to apply later, I'll take photos later once I've done all the rubbing down.

Thats 2 coats of EZE Kote and a very light sand over with 400 grit wet and dry. If I press too hard i could go through the glass  cloth to be honest I'm not impressed, the grain of the glass cloth still shows. I'll coat it once more with EZE Kote otherwise a good filler primer may be needed the surface isn't too bad at all i just expected a bit better.
As a side question do you think Z poxy would go over EZE Kote?.
Prop shaft & upper works soon.

Yes you can put Zpoxy over EzeKote 2thumbsup . I found out by accident. After modifying the inside of the Police Boat for my motor, I needed to re-seal an area. Having some mixed Zpoxy left from the outside, I used that. It went on OK, and is still OK Thumbup

I've Z poxy coated the outer hull it's dried but I'm giving it another day as I've been a bit liberal in covering it. I've started cutting out the upper works.
Photos to follow after a rub down ( the boat not me!).

Th hull has been rubbed down and I've fitted some decking, the new rudder tube, rudder servo, battery tray, mast mounting,  prop shaft and started carving out the mounting for the motor so that's just rough positioning.

I've fibreglassed in the prop shaft with some repair paste which is vile to work with and treated the deck with EZE Kote next will be rubbing strakes.

I've not been too idle but progress is painfully slow.
Shark boat Img_2059
interior with prop shaft and motor mounting plate.
Shark boat Img_2060
The window frames are made up of individual pieces I'm going to pin in place for a while as I'm bound to knock them off Sad
The cabin front windows are not yet finished I'll fit them next.
I've miscalculated and not got a speed controller to fit but I've got an old one I may give a test to if it's okay I'll extend the wiring as it's going under the decking aft of the cabin and what's there doesn't reach.
I'm going for a full lighted cabin and running lights but I've not got any to fit so I'll source them after Christmas.
There's little access inside owing to the main cabin being fixed in place so everything has to be threaded underneath it and given the large windows I've got to do a reasonable fit out to do it justice.

Slow progress but it's freezing in the workshop despite my little heater.

rubbing strakes started to fit the black blobs are pins holding them in place.
Shark boat Img_2062
motor in place I've got to get the wiring into the bow for the speed controller which I've decided is better there as there is a bit more headroom than below the rear deck.

A bit more progress:
Shark boat Img_2064
The bow has some of its pieces in place.
Shark boat Img_2065
The interior and foredeck is slowly taking shape.
I've not been idle but it's been cold and I'm scared of getting I'll plus work has been awful as I'm really not in the mood when I get back.
There's some filler needs sanding down on the deck as I couldn't get a good join hence the ragged white stuff along the deck edge.

Interior started, this needs to look at least presentable as the large windows make it visible. I've followed the plans too closely and the motor protrudes through the deck enough to make it noticeable. I've made a cover that goes over it which won't be too much but there's so many pins in it I'll clean it up first before I photo it.
The louvre door may well convince me to build model cars it's so fiddly.

And another view of the foredeck just because I'm amazed i made it fit.

Shark boat Img_2072
Remember my comments about not making much scrap- utter rubbish I've mis measured cut off square and broken more wood than ever over the last week.
The barrel back in the cabin floor is to cover the motor which is protruding i can't come up with any better solution. There is a table to be made which may distract the eye from it but it's there and I'll have to live with it.

First night in over a week as it's been way too cold and I don't want to get ill.
Prior to the freeze I listened to an online programme about landing craft and the way they handled owing to the flat bottom, as this is a shallow vee i did a bit of cutting and fitted a short keel which is similar to what I've seen on other versions of this boat.
Shark boat Img_2073[/url]
I've also fitted some fake strengthening plates that are on the original.
Shark boat Img_2074
hopefully a coat of primer will tone them down a bit as I don't like them.

A bit of slow progress and the start of priming I'm using a filler primer for the first layer. There's method in my madness as I was talking to a chap who restores cars and does up old boats and knows of my interest in model boats. There's a prominent red band around the top of the hull so yellow gives it a bit of a faded look right off if I don't slather it on, the rest of the hull is black which I can cover the yellow with and the upper works are a cream/whiteish tired looking scheme which yellow can be worked down from. I'm not convinced but he's shown me some work he's done and I think I can make it work.
Shark boat Img_2075
I can't spray anything this big in my workshop so I'm waiting for some good weather i did the first passes last weekend and got distracted by clearing up my bit of garden after winter.
