Stavanger by mikegerber - Scale 1:15 - RADIO - Colin Archer design

[mikegerber]

Hello again

 

Thank you all for so many likes and visits, especially Nils, Bob and Dimitris - well, I like to thank you for appreciation and encouragement!   

 

... Nils, your right, it is intended that hull and keel can be disassembled for transport or working and I am really pleased about the fact, that hull and keel fits almost seamless together.

 

Below you will find a gallery with the current state of the build, hull and keel have received their final finish and were fitted with primer. The somewhat rustic-looking appearance is quite deliberate (local polygonal running lines of the planking) - it is but an “old wooden pot“.   

 

Until the next ...

Mike

Very smoothe finish! Looking forward to see more of this build.

Hi Mike

 

Great job! Looking at your hull, you can see just how powerfully built those Colin Archer designed hulls were. Double ended. Powerfully proportioned.. Straight, long keel for directional stability. All of which indicate just how well designed they were for the conditions they sailed under.

 

I can't wait for the next update.

 

 

Cheers

Hello everyone

 

Thank you for your workshop visits and all the like-buttons - each time, it gives me a little pleasure. 

 

Kees, Patrick, Lawrence and Michael - all your appreciation means a lot! - thank you.   

 

... Patrick, It's effectively what you saying and with the build of the model I'm more and more familiar with Colin Archers design. Every detail makes incredible sense to me - here, Colin Archer has left nothing to chance.

 

... so my first attempt on detail work (see below) - brazing is yet to come!

Hi Mike

 

Wow! That's some beautiful metal work you've got there. Built to last, as they say...particularly as you're going to be sending your ship out into some pretty stormy waters (scale wise), that is. So, a dependable and robust rudder mechanism is definitely worthwhile.

 

As an aside, this is a lesson I learnt 25 years ago. I had built an RC scale model of Bruce King's Whitefin yacht; fully detailed inside, right down to the sinks, doors, etc. She took over two years to build. One day I took her out for a sail in the local river with a strong sea breeze. Off she went, beating into the wind against foot high waves. I moved the control stick on the transmitter to tack onto the other leg, and no response! I tried to bring her back by turning away from the wind and gybe. No response. All I could do was sit on the river bank and watch as she literally sailed off into the sea breeze away from me. Straight as an arrow. Sadly, I never ever saw her again! $1000 worth of sail winch, servos and batteries destined to never ever come back.

 

I can only surmise that something happened to the rudder, hence why she never responded. Therein lies my sad tale, hence why I'm impressed with your strong rudder mechanism! She'll be a strong as an ox.

 

Even to this day, I'm still traumatised!!!

 

Cheers

Mike, exquisite work on the rudder pintles.

 

Patrick, so sorry to hear about your loss, so unexpected I would be traumatized too.

[mikegerber]

Hi Patrick

Hi Michael

 

Patrick, this is a real horror story! It is not surprising that you have a trauma of this - I would also be shocked.

 

Actually I have already thought about such a problem and especially because "Stavanger" has no auxiliary motor. As old canoeist I will probably keep a canoe in position - but it's still a long way ...

 

Michael, thank you for your nice feedback. I must confess, that I have observed this approach on metal work in your pilot log - I will call it: "The Principle to cut and mill as much as possible - to solder as little as possible". I think, that this method works ideal for my options, since I am not very familiar with soldering technics.

 

Below:

Some little progress ...

The hinge pins are brazed

Still dry trying ...

Reminds me of the time I almost lost my footy (inexpensive beginners model) Voyager. I was getting ready to bring her in when she slipped out of receiver range and took off strait into the wind towards the center of Lake Elsinore; luckily I was able to flag down a person on a SeaDoo to retrieve the tiny vessel.

Excellent work as always Mike!! The metal work is perfect!! :)

Mike,

 

I read once that the Colin Archer hull- and sail design allows a perfect ballanced straight (even hard at wind ) course even without giving reasonable Support rudder, asuming the common sail lateral Center is set right......

Hi Lextin...(Mike I hope you don't mind - I don't mean to hijack your posts)

 

Hearing that your story about your footy Voyager had a nice and positive ending was good to see. Unfortunately, in my case, I can only surmise that the rudder linkage broke, causing the rudder to somehow jam in the midship position. Then, because the lee deck was completely awash, water must've have entered the hull and flooded the electronics because the winch did respond intermittently before it gave up with the sheets stuck in the close-hauled position. The wind was so strong (approx 30 knots), that it didn't matter what I did, it was just pushing the yacht further and further away from the shore.

 

Anyhow, such is life!

 

Cheers

Incredible work as always Mike, those pintle & gudgeon pairs look fabulous - I'm still utterly astounded that this is your 1st scratch built boat!

 

Looking forward to future posts, keep up the excellent work,

Hello everyone

Thanks to all visitors of the workshop and all assessments with the like button.

 

At the moment is some slack in the shipyard – for this, I was working on another project, as you can see below - a new vehicle for ... ?!

 

@John, Dimitris, Nils, Patrick and Row

I am very pleased to welcome you in “Stavangers“ workshop regularly and I appreciate your nice feedback - thank you so much! 

 

@Lextin

It's good to know an other RC sailors aboard! – and thank you for all your likes. Again and again, I am pleased about your "Byzantium" workshop. I follow it with great interest.

 

@Nils

... Yes, the ability to climb hard at wind was one of the main demands of these rescue boats and definitely, an appropriately balanced lateral plan is one of the keys to the main characteristics of a sail boat (see below: Derivation of CLR).

 

In case of “Stavanger“, the location of CLR is about 12% (measured in relation to the length of CWL) behind CE. Such a offset backwards of CLR (to CE) is considerable and prevents hard at wind a strong yaw to windward (luv). In this context another effect is, that in case of heavy heeling, the slender stern of a double ender hardly developed a affect to the location of buoyancy. This looks quite different for boats with a “fat rump“, since increased buoyancy at the stern means luv yaw.

 

After all my studies I'm convinced, that Colin Archer has highly perfected the mentioned properties in his RS boats.

 

@Patrick

... I mean, hijacking for this reasons is no problem - I appreciate all contributions - that shows the range of discussion topics.

 

@Row

... Indeed, it is a premiere - I know, with this build I got into something what frankly developed an unexpected dynamic. For example a veritable machine park has accumulated ... The extent to which this build in the meantime adopted, was not predictable for me - if I would have realized the magnitude of this project from the outset – I don't know ...  - I mean, the whole thing is a little bit crazy – It's not rational, but it's fun ...

Hey Mike

 

That's a glorious Sunshine, I must say! I hope she has many, many happy hours soaking up the surroundings and enjoying the ride.

 

All the very best.

Hello Mike

 

Well done, she is looking amazing; I am enjoying this & learning a lot. Archer was remarkable & is a hero of mine.

Thanks to all visitors of the workshop and all your support with the like button.

 

@Patrick and @Bob

Thank you for the warm words - Yes, we really have a lot of fun with the cargo-bike and while driving, our little girl gives comments about what she sees - chattering like a book.   

 

Maybe you like to check the cargo-bike on: http://larryvsharry.com

 

@Mark

I thank you for this nice feedback ...

 

... I allow to quote you in our mail exchange - you got there on the point:

„Reading about Archer as a person, he sounds obsessed by the technical, but beyond that he had an artists eye.“

 

I completely agree with you, Colin Archer had also this special artistic side. I think that is the fact of which makes his designs so fascinating and distinctive - the sober functionally-minded engineer paired with the artist.

 

till soon ...

Mike

[mikegerber]

... and what's happen in the workshop?

 

It was a great moment for me: To see her released from the jig!

 

 

Best regards.

[Omega1234]

Hi Mike

 

Wow and congratulations! She's looking beautiful, which is a credit to your workmanship and attention to detail.

 

A major milestone out of the way, that's for sure. Onwards and upwards now.

Hello everyone

Thanks to all visitors for showing in and all the assessments with the like button.

 

@Patrick

... „Onwards and upwards now“ ... – Yes!   

 

After long back and forth I decided to attach a waterproof epoxy layer only inside the hull - I've to much concerns, that by a external application, the wooden nature of the boat will suffering. Either way I hope that now everything is tight - a leak test will be done.

 

Best regards.

Mike

Hi Mike!

It looks great!

[Omega1234]

Hi Mike

 

Beautiful hull! I think you've made a good decision with the epoxy because it doesn't take much for water damage to occur; so a protected hull is definitely worthwhile. Having said that, have you decided what you're going to put on the outside of the hull yet?

 

 

Cheers

 

Patrick

[captainbob]

I used to mix up the epoxy and then thin it 50 / 50 with rubbing alcohol.  That would thin it to about like water and it would soak into the wood but as the alcohol evaporated it would leave a thin layer of epoxy.

 

Bob

[mikegerber]

Hello again

I would like to thank for all the many likes, which has received the last post!

 

@Igor

Thanks a lot!

... and of course I am pleased repeatedly on news from your RS1 shipyard.

 

@Parick

Many thanks to you too!

... In addition I have embedded a thin glass fibre tissue in the epoxy layer - I think that will hold. In the meantime the primary color concept is finished (see below) - there will be water resistant acrylic-based paints.

 

@Lawrence

Thanks a lot for the great feedback/comment and so many likes! - It means a lot.

 

@Bob

Thank you Bob, for this valuable tip with the rubbing alcohol (Isopropyl alcohol?).

 

Again and again I'm amazed about the vast of know how that is cumulated on MSW- there are answers to so many technical questions here! I should get used to ask more questions about unknown topics of mine ...

 

Best Regards.

Mike

[Omega1234]

Hi Mike

 

Many thanks. The colours you've shown will, of course (as in the full sized ships), really show off the beautiful Colin Archer lines.

 

Additionally, as you've said, the tissue paper will definitely add another layer of security and protection against water damage.

 

Can't wait for your next updates, because I can feel the waves beckoning for your ship to set sail.

 

Cheers and all the best

Yes, Isopropyl Alcohol.  A few year ago I said Alcohol and the response was "Vodka?" 

Another trick was to use nylon stockings instead of fiberglass in the epoxy.  It's not as strong as glass but it's plenty strong enough for models.  It is also lighter,  more flexible and easier to work with.

[mikegerber]

Hello everyone

Thanks to all visitors for showing in and all the assessments with the like button.

 

@ Patrick and Bob

Thanks a lot for your feedbacks! – Bob, I suspect the question concerning "Vodka" came from Russia, yes?  

 

To the shipyard ...

 

There was much detail work in the past few months concerning the preparations of the deck - I will report in the next logs. Among other things I spent a lot of time to gain clarity about the RC installation - or at least an idea of, before the deck gets closed. This is the reason for the long silence on “Stavanger's“ Log.

 

First of all, the marking of the CWL (respectively painting line) was necessary. Second was the first swimming test ... it was a full setback!  I had to realize that the hull was not ready for water at this time ...

 

 

 

 

 

 

 

... about my corrective measures in the next log.

 

Till then and all the best,

Mike

Hi Mike

 

I've been wondering what's been happening with your Stavenger, as she's been a bit quiet lately! It's good to see you back with this update.

 

I can sense your disappointment after your floatation test, because the same thing happened to one of my RC yachts a long time ago and I was not impressed! But, at the end of the day every problem has a solution.

 

I'm looking forward to your next log with the corrective measures you've applied.

 

Cheers and all the best!

 

PS - She looked really good floating in the water!
