Prototype build of ELLIE

[Bob Abell 2Participant @bobabell2]

Hello Red Leader

The cabin wall hasn`t split……..I didn`t have enough ply…..So I`ve joined it!

Cutting out the cabin formers now…..And take it from there

Bob

[Paul TParticipant @pault84577]

Bob

It is essential to fit the coaming before building the cabin as the design calls for a fairly tight fit

This cross section shows the relationship between the coaming (shown in green), cabin sides and cockpit floor.

The cross section also shows the importance of the cockpit bulkheads in setting the shape of the cabin walls and roof.

This drawing is the longitudinal section and shows the location of the cockpit bulkheads and floor (shown in red)

Paul

ps I have decided to call the MTB version Red Leader all I need now is a name for the Fast Fisher

Cut out the formers, which are roughly in position

They don`t quite fit because the hatch isn`t wide enough at the moment

I agree, the hatch combing is vital to the assembly proceedure

How about….."Blue Shark" for the fast fisher?……..or……"Stingray"

For the Cruiser…………."Miss Ellie"

Bob

[Dave_PParticipant @dave_p]

How about Manic Marlin as a name for the fast fishing boat?

Do these help

Hello Red Leader

Thank you for the very informative iso's

I've just about sussed it out now and I'm pleased to see the middle area is nice and robust

You sent me bulkheads 2 and 3 today which fit above formers 2 and 3…….Your iso doesn't show this!

I've planed off the deck overhang and modded the deck opening to 20mm annulus, so the.coaming can be fitted with confidence now

Speak again in the morning

Bob

[Paul TParticipant @pault84577]

Bob

The bulkhead not being shown on the iso…just checking that you are paying attention and regarding the deck opening don't forget to do the jam filling before fitting the coaming.

Paul

[Bob Abell 2Participant @bobabell2]

Paul…….I think I'm a rear bulkhead missing?

What's this jam filling you are on about?

Bob

[Paul TParticipant @pault84577]

Bob

Rear cabin bulkhead drawing sent by email,

re the jam filling I thought that one cryptic comment deserved a cryptic answer.

Paul. you are going to produce "notes, construction for the use of" for this set of plans?? I say this not because Bob is struggling (which he isnt of course) but most if not all plans usually are just that and dont include instructions. I dont think I saw a mission statement regarding notes??

I know it is very easy for chaps skilled in the dark arts of boat construction to correctly interpret drawings which leave newcomers baffled. This is why I dont normally build from plans, Its much easier if you make it up as you go along.

Case in point my Titanic..not built from plans (line drawings).. I struggled for ages to correlate the various deck levels and wells into plywood and removeable deck portions correctly.

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you Ashley

I was struggling with the cabin, because Paul hadn't shown the formers on the GA and I wrongly assumed he hadn't looked into it, in any depth

All is well now and construction will be obvious when ! post a few pictures

Been out all day, so has Paul…..now back on the job

Bob

[ashley needhamParticipant @ashleyneedham69188]

I often find that mulling over an issue for a day or so can pay dividends. Things that are tricky in the first instance can often sort themselves out by leaving them for a day, and sometimes it is a good ploy to walk away from a problem, and come back later.

Drawing things on scraps of paper is something i do a lot when faced with an "insurmountable" problem. Nothimg is tricky really, you just have to attack it in the right way.

Of course you are proving a plan, and so have to follow what the plan says. I hope you are keeping notes!

Ashley ps. cutting windows out…horrible job.

[Bob Abell 2Participant @bobabell2]

Work in progress picture, chaps…..

The deck overhang has been planed away, down to the hull walls…..That should please Red Leader

The deck opening has a 20mm wide annulus…..(rim)

The coaming (12mm x 3 mm) has been pushed into position and will be glued shortly

The coaming will form the curvature of the cabin walls.

Bulkheads will be positioned along the hull and will need adjusting for width and height

The bulkheads will be held in position by Black Magic and Fairey Dust!….ie……..I have no idea at the moment, but we will sort it out tomorrow, when the coaming glue has set!

It`s an interesting problem…………Don`t miss tomorrow`s exciting write up!

[Paul TParticipant @pault84577]

Bob

Start by building the cockpit

Then position the completed cockpit within the hull.

You can now use the cockpit, whilst sat in the hull, as a fixed point around which the rest of the superstructure can be built

The sequence of build is 1: Cockpit body. 2: Cabin sides. 3: Cabin internal bulkheads. 4: Cabin front & rear windows. 5: Cabin roof.

As you are using 1.5mm ply you will also need to add joint support / strengtheners to all intersecting joints such as the cabin walls / roof. You will also have to make some adjustments to the build as you progress owing to the design being based upon 4mm ply

On the positive side I found this to be the easiest part of the build and completed the entire superstructure in under half a day.

Paul

[Paul TParticipant @pault84577]

Dear all

I have been considering the motive power for the cabin cruiser and decided to re-introduce the single motor / prop combination as an option for this variant.

The thoughts behind this decision are that as a cabin cruiser the boat doesn't need a twin engine high speed power plant and it also allows the less experienced or those building on a tight budget a more acceptable alternative.

The layouts for the single engined design will be included within the the final set of drawings.

Paul

[Bob Abell 2Participant @bobabell2]

Morning, Red Leader

Coaming looking nice this morning

That's a good idea!………….Make the cockpit first!………..Roger on that………A good positive starting point

Need dimensions or words of wisdom to position the cockpit and formers along the hull?

If we knew where the formers go, we could glue pairs of strips on the inside walls and it would be a doddle!

I like the idea of a single motor for the cruiser……..Need dimensions, where to cut the keel

Bob

[Bob Abell 2Participant @bobabell2]

Paul

Former omitted on your iso

I'm using 5mm ply for the bulkheads

Bob

[Bob Abell 2Participant @bobabell2]

Paul

On the subject of Cockpit assembly…..

Would be nice to have tenon location with bottom and side walls?

(Put the tenons on the bottom and walls as they are not made yet)

er……..We could have done the same for the bulkheads too?

Bob in the Ideas dept

[Bob Abell 2Participant @bobabell2]

Latest state of play…..and Play………is the operative word!

I am really enjoying making this model……..It`s a sort of ………."Voyage of Discovery" !…….Into the unknown

Can`t do much at the moment…..Waiting for dimensions from Head Office

Hurry up, Paul……..Get that Wheatabix eaten!

Bob

[Dave_PParticipant @dave_p]

I think it is a good idea to have a single prop variant for the cabin cruiser for the reasons Paul has suggested. Plus I have an idea to make a slightly smaller version for my granddaughter so single prop would be ideal.

I have obtained a Stanley block plane like Bob's from the earlier suggested Old Tool site. It has been well used and the decorative finish is little tatty but I only paid £26 including post. The important thing is the blade is good and, as Bob has said, it is a lovely tool to use.

Build is looking good Bob.

Bob

Drawings sent by email.

Re tenon joints, don't you think this is a little ambitious given that we are trying to keep the design simple.

Paul

[Paul TParticipant @pault84577]

Dave

A smaller version would be possiable by simply reducing the size of the drawings on a photocopier but some adjustments would have to be made after the reduction to make allowances for frame and skin thickness.

Paul

[Dave MilbournParticipant @davemilbourn48782]

Dave

3/4 size would be a ten second operation on CAD and give a model 27" long. 6mm liteply keel; 3mm liteply frames and deck; 2mm liteply skins. Single 540/1 motor with 7.2v pack running a 35mm 3-blade prop. For grand-daiughter start with a 6v or even 4.8v pack! Easy peasy.

Dave M

[Paul TParticipant @pault84577]

Now Now Mr Milbourn

Dave might not have access to a computer running a compatible CAD programme so reducing the downloaded drawings on a photocopier might be the only option.

Paul

[Dave_PParticipant @dave_p]

Thanks for the advice Dave and Paul. I do have access to CAD program and had in mind to reduce the scale using such.

Dave, I like your suggestion for sizing etc. thanks. I do plan to build full size but wanted something for my little one to sail and call her own, that's if granddad gives her a chance of course

Dave
