Derek,

I am actually planking in 3 directions! 2 directions towards the turn of the keel, and one from the line of the main deck towards the superstructure deck.

The wood is cedar, cut from stairway supports, cost I think £20 for 4 lengths, and this is the third boat from that wood. :-))

I use this glue:

Derek,

Your comment about cardinal rules - I was wondering what you refer to?

I plank and build in a way that I have developed and works for me.

Could you post the setup you use when resawing the cedar into planks?  It might help those of us who want to mill our own planking in the future.   O0

The cedar was originally in 100mm square by 1m long pieces.

I asked the woodyard to cut the pieces into 10mm thick planks, giving me 36 planks at 100x10x1000mm and 4 small offcuts.

I then used my bandsaw to cut these planks into 2mm x 10mm x 1000mm planks. So, with mistakes and wastage I got about 180 planks at 2x10x100mm.

Ian says.....

Your comment about cardinal rules - I was wondering what you refer to?

1) start with one plank at deck level.......
2) one plank to one side then....install a mirror reverse to the other
3) then one plank butted into the keel plate
4) progress evenly toward the turn of bilge
5) be logical as each hull design is different

These may sound simple  O0 but many forget..... >>:-(... Derek

A few more planks fitted and the profile of the bow is starting to emerge.

More progress on the planking. You can see the planks working round from the keel have now met at the bow with the planks coming down from the deck. I alternate the required taper where they meet at the bow between the upper and lower planks.

It looks a mess at the moment, but mine always do at this stage :}

Looking good Ian, should be ready for the water in a fortnight at the speed you go  :-))    Oh is that ladder in the first pic to enable you to gain access to the work bench   {-)

Right then, I have now almost closed the hull, just a couple of stealers to fit in the turn of the bilges. Still a couple of rows to fit to get to the bridge deck level.

I have also cut and glued balsa into the stern ready for shaping, the bow will get the same approach.

Looking great Ian  :-)) ...the next cardinal rule is..........


Add glass fiber cloth & epoxy resin to the full internal hull surfaces between each frame x as many coats as you feel is necessry for the required strength

NB...this is prior to any external hull sanding

In OZ we have a 50 mm wide woven glass cloth that is self adhesive on one side only........works well in positioning & holding the cloth prior to the epoxy resin during the model hull building etc....Derek

Derek,

I can understand where you are coming from about glassing inside before external sanding. Its not an approach I have used before, I usually sand and glass externally before taking off the building jig and glassing inside.

I will give this some thought, as this hull is very different to any other I have done before, it may well be the way to go.

Thanks

Ian

Ian..... {-)...I suppose there must be 127 %% Cardinal rules with planking  <*<........

The stresses induced into the hull when planking should be minimal if Cardinal rules 3 to 12 inclusive are applied.....so I also understand your build/planking philosophy....Derek :-)

A little progress report, I won the first round battle with Col. Orbital Sander and his 120 grit troops, the pics are below.

But now, I am working at the bow where the hull meets the deck. The bit above the deck - sprayrail? is a nightmare, its a compund curve. The pics show the plywood template I had to develop to get somewhere near.

In case y'all thought I had abandoned this project, I haven't!

Been a bit busy with other stuff, including that delftship tutorial - all takes modelling time away <*<

Anyway, had some progress, but its just sanding, filling, sanding, filling....... so I wont bore you with pics.

When the hull is somewhere near it will have to come off the building board so I can locate the position of the main deck to allow work on scuppers, ports, anchor hatches etc

Looks lovely! I want one!

Such a pace you're working at too. I do that sometimes, then have big lulls where nothing happens :(

Hello

Very nice job. 

What about your Springer : where are the forward and aft side ?

Spent today shaping the stern and cutting holes for the scuppers and accomodation windows.

Hi Ian
Hi Xtian
and all other friends of the NOSES

Until now I thought I am the first and only man on the moon...
But what I can see here...  :-)) :-))
RESPECT!

Let me introduce my project:
Building is an AX102, one of the smallest BOWS in the fleet of noses (1,55m in 1/50 scale)
Start was in autumn 07 and now project grows on.
 
Your problems with drawings of UL are well known, this Model is a scratchbuild too.
Maybe we can complete some information here?

Ok, I'll try to upload some pics - empirically it did not work the first time...

greets
Pete

Your project is coming along very nicely, very impressive  :-)) How does it handle on the water with the shaped nose???

Very nice Peter.

What running gear do you have in her?

Also, I would be interested to hear how you have fitted the cargo deck, allowing for access to the running gear.

And, have you got removeable superstructure? If so, any chance of some pics of how you did it?

Hi

It runs well ;-)

Heavy wheather isn't testet at yet, but it runs well on normal ambient conditions.
There is less swell than with conventionel hull of my ABEILLE.  
It looks not as sensational as the typical "dent" at midship of normal hulls, but at same speed. There are only ~3 smaller waves,  probably  a better degree of efficiency?

In fact, we should scale down the characteristics of water in 1/50 to get a realistic effect of the nose...

The hull is powered by 2x35W (effective power)  Bühler engines at 75mm Raboesch props.
That will suffice to a upper scale speed but only less reserves to pull sth.
Be aware of the Gr...ner Voith-Schneider (as i mentioned to read above?). I've seen a Bow (about ~25kg) here in Germany with this propulsion,  but it didn't run well.  <:(

Pete


-in the meantime-
Oh...
Hello Ian
lets see...
-runinng gear is descibed above, that's what you mean?
-cargo deck is a "dummy". It's only a 0,5mm GFR with a under-contruction and wooden sheeting. I can lift it off complete, sealing of inner life is a level down.
- I can lift off the bridge (seldom used), and can pull out the rear wall of superstructure  like a drawer (?)

let's see if I can find some pics (and to wangle this d.mn javascript upload....)

Pete
