I can get the concavity out when we turn the hull over……No access at the moment

Fixing the final hull side in place, to use as a guide for the tricky bow section

The final skin is quite tricky…..I could fudge it, but it might attract your displeasure!…..So…….

It would be a great help.if you could post another Breasthook layer, halfway up the remaining space?

Still!……Not far to go now, then we can stand back and give it the dead codfish look?

Fitting out will be a diddle, compared to the skinning operation

Bob

[Paul TParticipant @pault84577]

Bob

By all means fit another horizontal panel especially if it makes your life easier.

I hadn't envisaged the skins being fitted in small sections as I had thought that each piece would be 'full length' did you have a problem getting long lengths of ply?

Paul

[Bob Abell 2Participant @bobabell2]

Nice to see you back with us again, Paul

The Brutus frame was about an inch longer than 48" and the ply sheet was just 48" max

So there would have been a joint somewhere

Full length side panels would be easy enough, but the hull bottom is a bit too complex for a single sheet

I'm working on the nose area now and was hoping that you could have produced the breasthook

I'm using one inch wide twisty strips of 1.5mm ply to get the basic structure, then finishing off with P38 where necessary

I've ordered the Brushless gear for SloMo and feel sure it will do well in Brutus

So everything is looking honky dory at the moment

Bob

[Paul TParticipant @pault84577]

Bob

There are already two 'breasthooks' already detailed. one at deck level and one at the chine (drawings 9 &10)

Brushless..wow

Paul

[Bob Abell 2Participant @bobabell2]

A Breasthook above the chine would be an interesting shape?

How much hollow should the hull be, underneath?….I`ve got 16mm at Formers 3 and 4

Bob

Don`t know what it is, but it`s not from me

Bob

[Paul TParticipant @pault84577]

Bob

Sorry old friend but I don't understand what you mean about 'hollow underneath' and where the 16mm measurement is taken from.

Paul

[Bob Abell 2Participant @bobabell2]

Tut tut Paul

If we place Brutus on a table, the right way up…..What would the gap be underneath?

Bob

[Bob Abell 2Participant @bobabell2]

Paul

Work in progress on the Bow skinning

Using 1.5mm ply with twist and it seems to be progressing well?

Notice the backup lips for supporting the ply pieces

We`re getting there….eh?

Bob

[Paul TParticipant @pault84577]

Bob

Now I understand your 'hollow' question and its my turn to say Tut Tut as the information can be extracted from drawing 8, however if we do turn the hull over and set the bow down on the table (and at 90deg to the table) the distance from table to hull, excluding the skin, at F3 is 30mm and at F4 is 36mm

I don't think that planking the bow will work as when you come to sand down the raised areas the skin will become to thin and fragile, when I calculated the option of planking for this area I ended up with planks no wider than 5mm and each plank was 6.5mm deep with 5mm rebates at each end.

[Bob Abell 2Participant @bobabell2]

Thank you Paul

I`ve got page 8, but it is under the build, so I can`t see the hull curve

What is the dimension with the skins on, please?

My thin planking follows the curve of the hull and the top straight edge

It starts in line with the hull slope and ends at the knife edge

There`s not much left in between!

If it thins in places, I`ll glue a ply doubler behind it

Don`t you agree it`s not far off?

I can get more bow by flatting off the sharp edges and adding deeper knife edges and also sanding down the middle section

Bob

[Paul TParticipant @pault84577]

Bob

The dims would be F3 25mm and F4 31mm, I agree that ply doublers will help with thickening the bow but most of all I agree that its not far off.

Paul

[ashley needhamParticipant @ashleyneedham69188]

I think to work as intended this bow area really has to be knife edge, especially I could imagine when making use of the VAST UNLIMITED power provided by the gosh!! BRUSHLESS motors! or the waves will not cleave and water will stick to the skin. ??

Ashley

[Dave MilbournParticipant @davemilbourn48782]

Now, now, young Ashley! Mind your tongue or Mr Slipper will come looking for legs to smack. Sarcasm is only the weapon of the intellectual when wielded by one; in the hands of anyone else it becomes the lowest form of wit.

Now go and write out a hundred times "People who make boats from hardboard are as mad as those who drink their own bathwater".

DM.

[Paul TParticipant @pault84577]

Bob

These are the true dims of distance to bottom of hull

Paul

What's wrong with baths…….. that's where I get all of my gin from

[ashley needhamParticipant @ashleyneedham69188]

DM, I am not sure my post contained sarcasm?? my usual sense of humour perhaps..

AlI ; was making the point that the bow may be the critical area whereby a good clean and sharp water entry is whats required, especially as the water needs to slide off the curves and not be stirred up and rise up the side.

it is very odd, but my negativly raked bow HMS Midge topedo boat exhibits a wave getting higher and higher up the bow before the front lifts and things look normal, it is most odd, as one expects the apparent wave height to steadily go down on gathering speed.

Re…having unlimited brushless power…..We all know what didnt happen to the original slo-mo despite great gobs of power..

Ashley

[Bob Abell 2Participant @bobabell2]

Now then! Ashley………..That sounds like sarcasm!

The original SloMo didn't reach expectations, but it was immense fun trying!

As the new SloMo and Brutus are, at present

Brutus is only a four footer, but it looks massive for some reason?

Any suggestions for a suitable colour scheme?

I think the razzle dazzle cammo would be very eye catching and sinister?

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Bob ,

Any colour but GREEN , a nice silver , with black trim , very retro ……………cheers Larry..

[Paul TParticipant @pault84577]

Colour scheme ……Black and grey is subtle and menacing.

[Diede van AbsParticipant @diedevanabs87670]

I'll have to go with Larry: silver with black trim, or if possible chrome… Makes it look like one of those badass gangsta leisure yachts.

Gray is too bland for a bad boy like this.

[Dave MilbournParticipant @davemilbourn48782]

Colour scheme ……Black and grey is subtle and menacing.

Same colour scheme as my "menacing" Toyota Verso. Bright flame red would be a bit more in keeping.

DM

[Bob Abell 2Participant @bobabell2]

Well chaps

I suggest we talk about the colour scheme when we see the finished product?

In the meantime, here she is!…………..Brutus!………….Fresh off the blocks and looking Razor sharp!

What do you think of your new born creation, Paul?

Will look even nicer with the formers removed and mounted on a sporty stand!

The waterline btw is surprisingly shallow…….It comes below the chine?………So I`ve ordered some special balsawood batteries!

Paul, the dimension I was after is 15mm…….I`ve got 16mm….So we are ok

Bob

[Paul TParticipant @pault84577]

Bob there is only one thing that I can say.

You have got the bow just right, I honestly cant tell you how good it makes me feel.

The watchers and lurkers might not appreciate just how much work you have put in to getting the hull to this stage….but I do and I am forever grateful to you for not loosing your faith in the design or in me.

Thank you

Paul

[Paul TParticipant @pault84577]

Re colour scheme these images might help focus some of the readers imaginations.

Bob

Re the waterline…the hull is intended to be very shallow and should draw no more than 30 > 35mm at the stern, remember how I said that this would be a challenging build……….well half the challenge is getting the right kit to make this greyhound go. 

Paul

[Bob Abell 2Participant @bobabell2]

WOW!………I'm very pleased you like the build so far, Paul, very satisfying

Have I got the info for the decking etc?

I've got the sketches of the stern area

I would like to fit a strip on the chine line to separate the undersurface and the hull sides and will make painting look tidy
