Shop floor to top floor

You'll swoon with shear delight, when you see it!

I'm on a roll now

The formers are taking a lot of time and effort…..3/8" ply takes some shaping!

Pictures in about one hour!

Ha! ha! Ha!…..(.Insane laughter)

Bob with arms going like Bee's wings!

[Bob Abell 2Participant @bobabell2]

Here we go, Paul

All the formers located on a central spine!………Like it?

The first set of pictures show work in progress, with the semi finished formers roughly in position

Bob

More following…

[Paul TParticipant @pault84577]

Cracking idea Gromit

I like the spine its a brilliant concept………..wish I had thought of it.

Paul

[Bob Abell 2Participant @bobabell2]

This set of pictures show the formers with temporary stringer material roughly in position, to show Paul how it will look eventually

The keel will be fitted as soon as the formers are finalised

What`s the verdict, Paul?

Bob

[Paul TParticipant @pault84577]

Looking good to me Bob but I will be a lot happier when the keel is in place.

[Bob Abell 2Participant @bobabell2]

Thanks Paul

Need to know how the stringers meet the keel prow, please

Bob

[Paul TParticipant @pault84577]

Hi Bob

Remember those instructions that I sent you……that you said you wouldn't need, lol

There are two horizontal frames in the bow that take the place of the stringers, you will find them on drawings 9 and 10

Thank you Paul

Can you show the transom in position, please

Is the keel flush with the top of the formers….ie….No keel?

Should have the keel on by tea time

Just got in from a campervan trip to Etherow……Very mild today

Bob

[Colin BishopModerator @colinbishop34627]

Lovely looking work Bob.

Colin

[Bob Abell 2Participant @bobabell2]

Thank you, Colin

I am enjoying the build, as the finished result is a complete mystery at the moment

We are expecting to be surprised with the performance…….Hopefully

I am impressed with Paul's CAD skills, especially predicting the former shapes and associated calculations

Bob

[Bob Abell 2Participant @bobabell2]

Hello Paul……You can stop worrying now!

It all fits together ok……But I don`t really know how the keel and formers should be?……The keel is almost flush with the hull surface?…….I think you`ve just sent me a cross section, I`ll have a look

The transom has a very sharp pointy bit……..Does the keel match it with a filler strip of some sort

To be honest it`s a bit too early to be asking these questions

Study the pictures and report back?

The first picture shows how the keel is almost flush with the hull bottom….ie……No keel?

The third picture shows the transom pointy bit, as mentioned

Anyway, Paul……..The build is great fun!

Bob….R & D Dept

[Paul TParticipant @pault84577]

Hi Bob

It looks very good and everything seems to fit as intended.

No keel showing but the keel timber will have to be shaped at the bow and stern to suit the hull profile.

The flat top of the transom fits flush with corner (straight meets curve) on the aft end of the keel.

Paul

[Bob Abell 2Participant @bobabell2]

How about this fairing for the transom crest?

Bob

[Paul TParticipant @pault84577]

Hi Bob

I'm sorry Bob but I didn't make this connection very clear on the drawings as the pointy bit of the transom fits flush with the base of the keel and the two stringer cutouts are for the deck stringer.

The keel to the rear of Frame 7 has to be shaped to accept the curved skin so the keel stringer will almost disappear.

Paul

[Bob Abell 2Participant @bobabell2]

Paul

The depth of the transom pointy bit is about 1/2" deeper than the land on the keel

Send a picture worth a thousand words!

Bob

[Paul TParticipant @pault84577]

Bob

You are right (as usual) the pointy bit is 12mm lower than the keel. The following image shows the relationship of F7 to the Transom (in red).

Sorry for missing that detail Bob, my excuse is that I am busy working up a set of sketches for a nice chap who wants to build a multi hulled, sea axe style futuristic warship (project Triton) currently the rough design is 2m long  and 0.5m at its widest point

Paul

[Bob Abell 2Participant @bobabell2]

2M long!……..Wow!

So….Is there a filler strip in front of the famous pointy bit?

I`m working on the Upper and Lower horizontal panels

Upper seems ok

Lower……If it`s supposed to line up with the stringer height…..Then the tenons are too wide

Picture to follow

Bob

Can you see what I`m on about?

Note, I`ve taken some weight out of the middle….We need the rim for clamping the ply

Edited By Bob Abell on 09/01/2014 15:09:39

[Paul TParticipant @pault84577]

Hi Bob

2m is the reduced version but not to worry as knowing the client has a restricted workshop the model will be designed to split into four pieces.

No there isn't a fillet piece as the transom and skins have to be 'worked' together, its a difficult detail as the transom is so slender but it should look super when finished.

The lower horizontal panel should line up with the chine stringer cut outs so please trim the tenons to suit.

Paul

[Paul TParticipant @pault84577]

Drawing Office to Shop Floor

I have just had the MD on asking why I was playing around with futuristic warships and not writing up the Brutus building instructions.

But when I explained who the client was and how much he wanted a statement piece for the next Haydock show I was given the nod to continue so the instructions might take a couple of days whilst I sketch up this Trident project.

The hard working designer is having his tea now.

[Bob Abell 2Participant @bobabell2]

That's very flattering, Mr Chief Engineer, sir

But don't you go working too hard!…..There's no need to over exert yourself

I've got my hands full at the moment, as you know

Sounds very exciting though!

I think a 3D illustration would be nice to look at first?

Bob

[Bob Abell 2Participant @bobabell2]

Shop floor to him upstairs!

The upper and lower panels fit ok, Paul

I`m clockin` off now

Bob

[Amy jane SeptemberParticipant @amyjaneseptember49770]

You're really flying along there Bob, A nice work shop, plenty of time, I'm sooo jealous!

[Bob Abell 2Participant @bobabell2]

Thank you, Amy for your kind comments

Finally got the structure set up to my engineering satisfaction!………lol

Everything lined up and dead square etc……..Note the steel rule clamped to the spine, to eradicate any bowing.

The problem now is that I`ve not used the glue yet!

Can`t possibly dismantle it all, so I`m going to "Tack weld" all round with glue seams and reinforcing where necessary with balsa strips

Bob

[Andy CParticipant @andyc56856]

Looking good Bob. I like the holes in the frames for added lightness. Was that done with a router or drill and sanding?

Andy

[Bob Abell 2Participant @bobabell2]

Hello Andy

Thanks for your comments

Cutting those slots out was quite a big job, in 3/8" plywood too

I drilled a hole at each end then cut the slots out with a fretsaw and cleaned up with a file

Can't see them doing much good, but they do look technical?

Now in the process of applying the glue

I'm really enjoying the build

Bob
