Many thanks F1 Madness.
P.M.sent.
Will add the spray rails anyway, as I think you are right in your observations.

Mike.

I would,be a shame to finish it then if it did need them you'd have to add them after all the work getting a nice finish on it.

They are for deflecting displaced water outward and away from the hull. The picture shows 3 below the chine

Hi there, sadly the answer given to spray rails is only (partly) right.  The most important one has bean missed out in that:

Is number 4 spray rail this one?

 

(As I tried to point out ina earlier post) –this is the main one and it can come in many forms.  The rail in the photo above and in the aquarama photo the sprayrail is built into the hull as a flat area - that is at the chine between the V of the bottom and the side of the hull. This spray rail’s job is to prevent water climbing up the side of the hull and creating a grater wetted area there for generating more drag and a wetter top deck

 

hope this helps

 

aye

Hello all.

Work done today. Roughly finished the after "Slipway" as the Italians call it, not glued up yet as it may need altering when the transom is complete.

Fitted the first of the Mahogany planks with the two chine guide planks and then the first keel layers, did soak the keel ones before gluing just to get them to lay flat.

The other pictures are of my facilities really, I don't have many tools etc. but do have a lovely sanding table which I made many years ago from an old washing machine motor and some left over Formica worktop.
It is 9" diameter and with the 3/4 H.P. induction motor, cannot be stopped no matter how hard you push, just replaced the  abrasive with new 80 grit alu oxide.

The other bits are self explanatory, including my Pool Noodle sanding thingy's which are absolutely great, just wrap around the grit of your choice, stick with gaffa tape and you are ready to go.

Hope this thread is not becoming too boring, please say so if it is.

Mike.

What about these little devils.

40mm x 28mm x 30mm high with on/off switch, cooling fans and 60 amp constant. Fwd / Reverse etc. with BEC.

Have changed the power feed to the fans as the can't tolerate any more than 2 cells Li-Po, although the controller can take 3 cells.

The prog card saves a lot of time and for a fiver you have to have one.

Sorry Mad Mike, I think fans are the way to go, although, I will still water cool the motors.  ;)

Am going to fit a larger fan, extraction mode to the "Engine Room" so should work out O.K, if not easy to revert back.

Mike.

Some more work on the model today.

Bottom planking progressing nicely, absolutely love working with this Mahogany, very hard and holds a very sharp edge.
Pleased with the bow so far, joints seem quite tidy, although a lot of sanding to be done later.
Trial fitted the running gear on the finished layer, opened the prop shaft holes with the aid of a home made tool and they are quite acceptable, very little filling to be done.

The picts show both the 40mm and 35mm props, have set the shaft angle to accommodate both sizes.
Need a couple of posts to accommodate the pictures.

6 more planks fitted today, it's taking about 15 mins to complete each plank, what with shaping, sanding and bevelling them.
Going to be quite a little while on this stage.
Anyway, needs must so have to get on now.

Mike,
Excuse me if you've already said but...what method are you using to attach the mahogany planking? The last time I tried this I had a awful time getting it to stay flat.
Looking good, by the way.

Hello Robert.

I am using the yellow Aliphatic Resin glue, there are some other yellow wood glues out there but nothing comes close to the real stuff.

Do you find that the planks try to curl before the glue dries?

Haven't had that happen yet. My planks are 1.5mm thick so maybe that helps, mind you, I do pin each plank down using 0.5mm brass pins using a pin pusher.

Ah. That probably would help, yes. The ones I was using were very, very thin indeed.
