Prototype build of ELLIE

[Paul TParticipant @pault84577]

Hello Bob

The bow clamp is an excellent idea and, if you don't mind, I will include it as a professional hint within the building instructions. Perhaps I should entitle them Bob the Boat Builder hints and tips.

Shop floor to drawing office…..

Thank you, Paul

Similar ideas are really obvious when doing the build….Necessity is the motherhood of invention, you may recall

When we start on the 6 mm square stuff…..Where does the strip each side of the keel end at the bows?

Hello Paul,

What cad software are you using..?… cheers Larry..

[Paul TParticipant @pault84577]

Hello Larry

Its TurboCad 19Pro Platinum, I have used TurboCad for years and find it a lot easier to use than AutoCad

How are you getting on?

Paul

[Paul TParticipant @pault84577]

Bob

If you start fixing the stringers from the stern they naturally fall into the correct position when they meet the bow.

Paul

[LARRY WHETTONParticipant @larrywhetton68737]

Hello Paul,

THank you asking more tests tuesday, cad software looks good,

i have draftsite on my pages use it no and then ,

but to a bit old school still use board and compases and set square and of coures no one tee,

tend to do the old ismetric scetches,

old site dodges for the the lads who can not understand the drawings,

build looking good shop floor is catching up ..……….cheers Larry…

[Bob Abell 2Participant @bobabell2]

Nice to see you back in action, Larry, CAD is quite easy really. I use it whenever possible. It`s great fun and so precise

Shop floor is doing ok too

Reached the stringer stage, and of course they don`t quite fit!

Got some very tight bends to get round now, The Drawing office suggest cutting the back edge every 5mm, as they do in violin making, then bending round a suitable template

Sounds a good idea, could also use laminations or cutting the curve out of plywood….All food for thought

All part of the fun…..Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hello Bob,

Surgest you build up stringers with several lamnaitions of required stringer ie/ 1/4 x1/16 layers

bend easy this the way i do it .no saw cuts just glue the first one ,have a cup of tea then a nother

then repeat untill happy this is a strong stringer, timber of chioce is yours i use Ikea blind ,

strip cut on the trusty band saw, hope this helps,

watching with interest, like a site forum ………cheers Larrry…

You have another customer here Paul and Bob. I have just read through this thread and thoroughly enjoyed it. Love the idea of funds going to charity.

Due to personal problems with family, health and work I have been in the modelling doldrums for quite along time now with a few false starts including an embarrassing episode with a plastic hull and a bottle of EMA plastic weld.

The bug has slowly been coming back and this project has really sparked my interest. My modelling den or man cave as SWMBO calls it has been sorted the desk has been cleared and tools are ready for action.

Thanks for your hard work and regular posts, it is a great insight into drawing and testing model plans.

All the best

DaveP

Hello Dave

You will have made Paul very happy with your very kind words of encouragement!

He has worked hard on this project for many months now and as we all know, Paul is not in the best of health

It will be very nice, once the design stage is over, to see member's models being produced, with questions being asked….and we are here to answer your queries

Some stages of the build are now appearing to be quite tricky, especially the stringer and hull cladding.

I've actually been spelling doom and gloom, every time a problem has cropped up, but good old Paul has not batted an eyelid and come up with some Golden Words of wisdom!

Some of you , like me, will be surprised at the unusual shape of the hull! It seems to have a few very aggressive contours to tax the skills of the builder!

I am very pleased and in a way humbled to be invited to build this very important prototype of Paul's model

Thank you, Paul and thank you, Dave

Bob….Up to his neck in muck and bullets!

[Paul TParticipant @pault84577]

It is very encouraging to see so many people becoming involved with this thread I only hope that my design lives upto everyone's expectation.

Bob is testing the design with gusto and whilst he is more than skilled enough to build this model without asking questions he has the wisdom to look at the design through the eyes of a beginner and is raising queries that a first timer might be to embarrassed to ask.

The ultimate result of this exercise is to enable me to fine tune the designs and produce a set of building instructions that will allow a beginner to tackle a moderately difficult build.

I firmly believe that a picture is worth a thousand words and with Bobs practical help I have been producing a series of step by step drawings that cover every step of the build.

Our recent discussions have been about how the chine stringer forms a compound curve between frame 2, frame 1 and the bow. As Bob says this is a very tight curve but as its shape is essential to the finished model we have been chatting about which is the best way to make it work.

There are easier ways to build a cabin cruiser hull but this model has 2 other variants and it is these faster boats that require this particular shape of hull.

As always this thread is open for comments and I do appreciate everything that is contributed by forum members.

Workhouse to Powerhouse

A lovely set of drawings, Paul……….and so Abelly done!………They`ve come in the nick of time!

Now then…… I have a cunning plan, my Lord!……….And what`s that, Baldrick?

Let`s give the stringers a reference?………K for the keel supports……..M for the middle…..and B for the bulwalks?

Stringer K is no problem and will be lovely to fit

Stringer M will stop at Former 2 ……….The short piece from Former 2 is very nearly a straight line and can easily pass through Former 1 and meet the keel prow where it will be chamfered off accordingly

Stringer B will go as far as Former 1, a "little back" sawing will be required

(Paul will make a little sketch, showing his method of "back sawing" as a neat method of achieving stringer bends)

Stringer B end piece, from Former 1 to the prow, can be a short length of shaped plywood

The nice feature of this last loose piece, means that the nose clamp can stay in position, for rigidity during the fitting of the top hull sheeting

Stringers sorted and Bob`s yer Uncle!

The above master plan, came to me in a flash of genius, this morning!

Feeling very pleased with myself now……..Uncle Bob

Hi, Bob and Paul…

>>As always this thread is open for comments and I do appreciate everything that is contributed by forum members.<<

Thanks for that, I don't feel like I am butting in now…..lol

I have been following this thread with great interest and will gather all the info and ply wood to start this project at a later date.

Best regards, with the project.

Ian

[Bob Abell 2Participant @bobabell2]

Thank you, Ian

Your comments are very welcome

Now for some exciting pictures to waken up the jaded pallette?

A mock up of the prow area!……With a few noteable tit bits to talk about!

Stringer K is no problem and will make a good foundation for the top sheeting

Stringer M ends at Former2

Look how straight the final piece of Stringer M is? We could use an extra deep piece of 6mm wood and simply shape the slight curvature….ie…..No need for a bend!

Also in the picture are a couple of fresh sharp sanding blocks for adjusting the former notches…….You could be making a few of these in the mean time?

You`ll have to wait for Stringer B

Now take a look at this little ditty…..

These are my "fit anywhere" S Hooks!

Two pieces of wire, bent into shape with one or two lacky bands? Perfect for holding the stringers in place

Something else to make while we are waiting for the drawings being issued

Good morning Bob,

Nice to see production is on the way and you solved stringer bend problem,

the bow finish looks a little sharp , are useing solid block here ?,

cheers Larry..

[Bob Abell 2Participant @bobabell2]

Morning Larry

There`s no need to use block now…..We`ve solved the bend problem now…..Hopefully

The bows are very sharp in certain areas……..Paul is fully aware and quite happy

The cruiser doesn`t need such a shape, but we can pretend the Broads Cruiser was built on an ex MOD hull?

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hello Bob,

Thank you for reply , when are plan plans on release..?…

cheers Larry….

[Bob Abell 2Participant @bobabell2]

Hello Larry

We don't know at the moment, when the plans will be available

I would think that Paul will release the hull as the first issue, followed later by the various options

We must be sure that the hull is well and truly sorted before the plan goes on sale

Things are looking good chaps. Latest pics are very encouraging. Like Ian, I was a little concerned about the bow section and had in mind to use jelutong or balsa block but will wait and see what you chaps have in mind now.

I have checked my very small timber store and found some nice 6mm ply for the ribs but not long enough for the keel so am having a look around. Shock, horror, I may have to buy some. Also found a sheet of 1.5mm which I will use for hull skin.

Dave's Dock gates are closed and basin is being pumped dry ready for keel laying.

 

Like the S hooks and lacky bands Bob. Great idea.

I recently purchased a bag of bands containing lots of various sizes from 99p shop now I have a use for them.

[Bob Abell 2Participant @bobabell2]

Hello Dave

Glad you like the latest progress report

The next step is to make sure the general skeletal frame is correct with no lumps and bumps

Got to admit, the hull skinning is not straight forward in the bows area

Only time will tell

Bob

[Dave_PParticipant @dave_p]

I will be away from home working this week and may not be able to logon to this site via company laptop but look forward to catching up on Friday.

Keep up the good work chaps.

Dave

[Bob Abell 2Participant @bobabell2]

Hello chaps

At the moment, Paul is temporarily indisposed

I will be trueing up the structure next, but there are a few formers, slightly out of plonk!

The plan is to record any formers with special disagreeable features for future reference! And can be referred to, as and when the plans are released

One particular oddity is the depth of slots in Former 1, where Stringer B fits….(Bulwalk)

The slot as drawn is only 2mm and should be 6mm?

I can see that Paul is on the thread at the moment, so things may be looking up?

Bob

[Paul TParticipant @pault84577]

Hello Bob

The reason behing the slot only being 2mm is to allow for shaping the stringer, the sketch below shows a section of Frame 1 and better explains what I mean.

The frame section is shown upside down and the blue dashed line indicates the extended line of the hull, the black dashed box show the stringer before shaping.

Paul
