Hello Bob

Now that you are carrying the mantle of Chief Designer you will have to be more precise about your measurements,

Four laminated layers equal 12 mm

You haven't included the glue between the laminations

Paul

[Bob Abell 2Participant @bobabell2]

What are you on about, …Chief Designer.,……..I haven't got any wood at all now, and hardboard is keeping the build going

It looks OK to me

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob. The hardboard will be fine, just make sure it is well sealed. Use thinned undercoat first etc.

In theory, if you steam it, it will bend to fit some of your curves. In fact, if you had a mould, it is just possible that you could press it into shape(s)…..?

Ashley

[Bob Abell 2Participant @bobabell2]

Thanks Ashley

I`m quite happy with the hardboard strips, the Evostik is doing a great job and it sets like concrete

It`s quite rewarding building a boat out of recycled materials

I`m about to order the 1mm plywood now, then it will take off!

Bob

[Bob Abell 2Participant @bobabell2]

Latest picture of the epic stringer build

It feels very strong now and looking forward to the ply sheeting exercise shortly

Bob

[Bob Abell 2Participant @bobabell2]

More progress pictures. I realise they all look the same lately, but progress is slow but sure!

Now we`ve come to the Transom area, going off the last build, I recall, we had a problem at this end Mm?

Will to get the old pix out

Paul…….Is the latest Transom frame correct?

The stringer notches look suspicious

Hi Bob,

I think you maybe building a Thames slipper launch, it looks similar 😄

Keep going you will get there 👍

Regards Ray

Bob

I'm sorry to say that I am not sure as it was so long ago

But after extensive research on the dark web and at great personal cost I have found part of an amazing and mystical archive that is full of construction photos and might just be the answer to your problem.

These images clearly shows the part in question and how the builder overcame these problems, if only we knew who this master builder was as his full archive could answer all of your questions.

[Bob Abell 2Participant @bobabell2]

Thanks Paul

I already have your photos

I'll just struggle through and sort it out

Bob

[Paul TParticipant @pault84577]

Bob

I do remember some discussion about the transom when you built the first one, in retrospect I should have given the stern greater depth but at the time I had a fixation on making the stern appear to slide into the water.

Like Ray said it was very much like a slipper launch.

There is a possibility that I changed the design of the stern in order to overcome construction problems but these changes would have been picked up on the drawings that you are using.

I will go back to the thread that covered the original build and see what was said and done but meanwhile could you explain what you mean by The stringer notches look suspicious? Are they too big, too small, in the wrong location or just baffling

Paul

[Bob Abell 2Participant @bobabell2]

Hi Paul

I`ve got it sorted out now

Not much of a problem, the problem was caused by me thinking the sponson shape was correct

The notches on the sponson were such that they rested on top of the upper stringer

Anyway, see my latest progress photo

Bob

[Bob Abell 2Participant @bobabell2]

The frame is just about finished now, needs a bit of trimming here n there, but….

It has turned out better than expected, considering that it is made from Hardboard mostly

Now for the sheet covering, now that the shops may be open again?

Bob

[Paul TParticipant @pault84577]

Hello Captain Bob

It is looking very good and a lot more substantial than the original, where are you planning to fit the forward rudder (between frame 1 and 2?)

Paul

[Bob Abell 2Participant @bobabell2]

Thanks Paul, I like it too

Got the Transom sorted out now, I just removed the outer tabs and it was kinda obvious after that

So you like the idea of a forward ish rudder, afterall?

I think it will be ok between Formers One and Two and will be nice to see how she behaves?

I`m hoping to fit a cannon, in line with the rudder shaft so that it can rotate with the rudder?

At the moment, we`ve got a tremendous rain storm here with buckets of Hailstone too!

Keep safe, out there and all the Forum readers too

Bob

[Paul TParticipant @pault84577]

Hello Captain Bob

Yes I like the idea of a forward mounted rudder especially when used with tank steering. One problem though could be protecting it from damage as it will be very exposed, There is an obvious and simple modification that would protect the rudder and help with straight line stability but I don't want to interfere with your super build as you could already have a better idea.

We had hailstone last night, big bug-ers and sounded like someone was throwing gravel at the windows.

Paul

[Bob Abell 2Participant @bobabell2]

Hope to receive the thin ply today…….From SLEK

Got the hull bottom in a ship shape condition

The workshop is looking very busy once again….See picture

Bob

[Ray Wood 3Participant @raywood3]

Hi Bob,

Your going to need some more shelves for your models soon 😄👍

Regards Ray

[Bob Abell 2Participant @bobabell2]

Hi Ray

I do have another play room next door, but no shelves and no wood either!

Have you noticed how the shelves are all held together with an assortment on clamps!

Look after yourself

Bob

[Paul TParticipant @pault84577]

Good Afternoon Captain Bob

How thick is the ply?

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

I've ordered 1mm, 2 mm, 3 mm 4 mm and 6 mm

I'm hoping the 1 mm my will do the job

I know you won't agree but wth suitable supporting strips, the 1 mm wil be ok?

If it looks a bit too thin, them I'll get some thicker stuff

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob. 1mm should be fine if supported by ad-hoc supports. It may bow a bit but this is very realistic, google pictures of warships in the sun and you will see the wobbliness of the plates nowadays.

If only Bob made some boxes for his boats they would stack nicely on the floor (upwards) and having cord or rope handles on them would make them much easier to lug about.

Bob. Please remove the clamp and fix the shelf properly please!! You are an engineer….

Ashley

[Paul TParticipant @pault84577]

Bob

You have built a substantial frame with plenty of stiffness so 1mm ply might be thick enough, the only downside might be impact damage when the hull hits an obstruction.

Paul

[Bob Abell 2Participant @bobabell2]

Thank you Ashley, for your concern……

er………Which clamp are you referring to?

I`ve got ten clamps usefully employed holding stuff up

Just to please you though, I`ve fitted a strut under the Slo Mo shelf

Boxes?…….D`yer think wood grows on trees?

Bob

[ashley needhamParticipant @ashleyneedham69188]

Now don’t give me that Bob….you should have had 4mm ply in AGES ago to box up yer boats!

Its the only way to store and transport them.

Yes the Slo-Mo shelf!

As the boat you are building is another whopper then perhaps 1.5mm ply might be used especially as PT says, better resistance to unintended impacts.

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you, Ashley, for your sound advice

The boxes will need to be very big and hence…..Very heavy too

At the moment, they look very on the rickety shelves

Back to the real world………The plywood failed to materialise yesterday, just as I thought

Bob
