The Argie 15 kit build

This came in from Andreas last week.

Hi Roy
Some foto’s




In this case we sold the Dix Design Argie 15 plans to Andreas and he did his own setting out.


The design comes out of six sheets of 6mm okoume marine plywood, so a lot of setting out and electric jigsaw work, you get there in the end though.



Check the assembly and the drawings, they take you through each stage, step by step.

Argie 15 plans or a kit and related materials can be bought direct from CKD Boats cc, they are all cheaper than you would think!
 
We have placed the order for the complete North Sails and Ronstan deck gear package for this boat and will send to Andreas when they are ready.
Check the design on the SA Yacht Blog

The boat in the picture was built from one of our CNC cut kits.

Packing the Didi Mini Transat Mk3

The export orders always go into a purpose made crate, the norm is using 16mm chipboard, cut to size to give just enough space to allow the plys and in this case the CNC shaped rudders to fit.


Due to the space such a crate takes, we had the plys loaded with the crate against the wall pending on collection day.

 
The rudders were laminated and CNC cut to shape so that the customer could do final shaping himself. The envelope is a Lucky Packet of odds and bobs we send with most kits.
 
 
Steel band strapped, our crated kits have shipped world wide like this for over a decade and allow
safe handling and when the customer receives his kit boat order it is in the same condition we sent it in.
 
The shipping lable was attatched later, this order will go to Dubai, UAE, country number 35 we have exported to I think.

A view of Hout Bays weather today

The weather is typical wintery stuff, changeable, wind and rain with heavy hail and thunder at times but
otherwise really nice when the sun comes out.


Same 1600i Ford Bantam, same wonderful view and on the way back from another boat kit delivery and back to office to check mails.

Nice job? well no complaints!

How to move a Proteus 106 sail boat by road

In this case its a larger version and with the extended transom, built in Thailand for Rick
it looks like moving was not too difficult and I think they launched off the beach?


As our plys and MDF stations kit weighs some 2600 kgs, the epoxy 150 kgs, all up and when complete this will  still be a light displacement boat, good for sailing of course.

The need to move such a load on a national highway will require a road legal wide bed trailer and licenced rig driver.

Proteus 106 kit packing

Monday morning:

This is to a local order for a customer on the South African East Coast, for all exports we pack in purpose made crates and this size order would need at least two such crates.


The trick is to pack what can be lifted by the Hyster, at over 2000 kgs this size Hyster would have none of this and just would not lift the order.



A plan was made for a larger Hyster and we then steel band the order to ensure it stayed as one pack lot and arrived in good condition.

The odd shapes in between are 16mm MDF cut outs which are removable bulkhead stations.

The load weighs about 2600 kgs? we supplied 150 kgs of epoxy with this order as well.

http://ckdboats.blogspot.com/2010/01/erminios-proteus-106-catamaran-build.html

This large catamaran is built the right way up and then becomes an easy build with no later worry about turning it over at a later stage.

News in by thursday:

Hi Roy

The kit arrived yesterday late afternoon - all intact and no apparent damage. I haven’t unpacked and checked everything yet.

Many thanks

Hout Bay today

Actually this was yesterday but the weather is much the same today again!

The view is across Hout Bay in South Africa, the Sentinal is the name for the pointed cliff on the far side and behind that is Karbonklberg.

Read wikipedia for more http://en.wikipedia.org/wiki/Karbonkelberg

Roys Foils and Rudders

Thats a new name in the yachting industry?

Having just laminated a Didi Sport 15 keel foil up and with the rudder to be done next, followed by a Sadler 26 rudder after that its clear it may be a suitable name?


Dix Design have supplied us the CNC cut files to profile the foil and rudder.

We then slot the shape into the wood on both sides with a sideways groove every 50mm, this means
we can release the actual shape in a controled manner.

Drawing # 8 says to laminate with recorcinol or epoxy, we always use recorcinol.

Applied to both edges to be laminated it really soaks into the wood, which in this case is african mahogany (khaya)


Check the link to view the Didi Sport 15 boat.

http://www.dixdesign.com/DS15.htm


One foil blank ready for the CNC works


The timber for the rudder laid out on the foil blank but not glued.


The rudder timbers are now laminated and will be at the CNC shop in the morning.


Released from the clamps,the phenolic glue is in the plastic container and plastic bag, the curled black thing is what was left over from the keel foil glue up.


The two blanks are now ready for CNC works.

How easy is this? sort of when you have done it this many times.

Yamaha turntable and audio feed back

Hi Roy,

Earthing via the mains electrical earth is possible but not advisable. If you do encounter an earth leakage situation from another appliance it will be expensive....   This is almost a guaranteed outcome unfortunately, unless you also have a very sensitive surge arrester or similar.

Cheers,

J

See http://www.ehow.com/how_4896756_ground-stereo-receiver.html


Please read the above at least twice before copying what I have tried below!

Thanks Justin.

The service of a Yamaha turntable was posted some time back.

http://ckdboats.blogspot.com/2012/06/how-to-service-yamaha-p-320-turntable.html

There is a series of pictures in the link showing the opening and cleaning of the turntable that I bought new from Hamrad in Cape Town.



However I have continued to be wondering why there is feedback when the clear plastic lid is lifted and a record is playing, its fine when I am not touching the player.

This is what the trouble was caused by:

These sets and the audio amplifier by Sony are both connected to 220v electric supply with a two core wire, so positive and negative, there is no ground or earth wire, why?

The turntable has an earth wire which is part of the white and red audio wire loom, the back of the Sony amp has a ground connection which the earth wire connects to but when handling that earth pin with the set powered up gives a lot of noise, why?

The reason was simple, there was no continued earth or ground wire  feed to the buildings power supply.

I took a single wire from the amplifier and then to the power plugs earth pin, unused as there were only the two wires to connect, positive and negative. With the single earth wire connected to the buildings ground system the feedback was gone, simple fix!

How easy was that?

Roy

Note, I would suggest that if your not qualified to do such connections or have doubt in your ability to employ someone who is qualified, at all times make changes and connections with the power switched off and with the power supply wall plug removed.

I was going to delete this entire posting as I have obviously made a mistake and posted an error but on thinking about it the post may just stop some person from making the same mistake?

I have removed the ground wire to the domestic power supply earth, next I will run the ground wire to the domestic water supply copper pipes which are in the roof space close by.

The Sony amp and Yamaha turntable were later grounded to the Akai music center, we use the audio tape and CD side on that. This seems to have acted as a large enough ground and so far the feed back has stopped!

Etch primers for rudder painting


Rudder etch primer coating.
 
We used a special twin pack etch primer on this rudder which would make a great bond to the tie coat before antifoul application.

Irwin 54 rudder etch primed

This is always a nice part of the job,it finishes the process as far as we are concerned too,the next step is to hang the rudder and apply International Paints Interprotect primer.The paint we have used is also an etch primer and a twin pack,two coats with a foam roller covers just about anything,it will etch to metals,epoxies and GRP.


The job needs two more applications on the otherside,I can then close for a bit of a break having worked through the Christmas and New Year holidays,there was little choice if yacht Chessie,the Irwin 54, this rudder will fit, was to have a chance of starting the next leg of the ARC Around the World Rally next saturday the 8th of January 2011 starting in Hout Bay.

The Irwin 54 rudder kit



Yes, we have this in our CNC files now!

The Irwin 54 rudder glass work


Next will be sanding and  filler coats of  more sanding epoxy to fill up the grain from the biaxial weave cloth,we then fine fill with our Pro Fair fairing filler.
Each section of a build like this is a series of processes,all repeats  in many ways,its time consuming for sure,here we are applying the biaxial glass cloth and our own brand of epoxies.

Rudder and foil manufacture



 
 
With three orders to either rudders and foils now on the go we look to be accepted for such work?
In fact we have been making such items for years, with a 316 Stainless shop as a sub contractor we
can often supply the stainless fittings also.

Rudders and Foils from CKD Boats

Made to order and often as extras to the boats base kit, we can supply foils in a basic CNC shape format or fully finished and ready to fit.


These are to the Didi Mini Transat ( mini 650) one rudder is on the bench.

We can supply to other boat designs, such as the Irwin 54, Holiday 23, Didi 26, Sadler 34 and others.

Proteus 106 CNC cut panels

These are just three of some 120 panels that go to make the Proteus 106 catamaran kit. This one is special to South Africa as it will be assembled on the east coast and we will soon have a series of build pictures.

The order will be collected next week and will be transported to the build site for home construction.

 

Imagine setting this out by hand then cutting it out with an electric jig saw!


With spot on accuracy from the CNC machine and being repeatable we can make one designs time after time and once the first boat produced has been measured there will be little point in measuring those builds that follow?

Roy

A new Sadler 26 rudder

I say new and it will be but this original Sadler 26 which was GRP moulded here in Cape Town by Fortuna Marine needs its first rudder made. Even some thirty years on, this boat is still a top design in this size of boat.



We will make the rudder to sizes as supplied by Dave who has circumnavigated in his Sadler 26, with ownership still and after some thirty years, thanks to him we now have the original 1986 rudder and pintal design and can construct to the designers drawing and instruction sheet supplied.

How easy is this, keep watching and you will find out.

Rudders and foils are nothing new to us, check the link and date that we worked on the Irwin 54 replacement rudder.

Update:

We now have the rudders dimensions and will bond the 12mm okoume marine blade together this week for shaping next week.

Yacht Voortrekker, an update by Frans

The way news comes in often amazes me but it does come in, we may wait months even years but then someone reads my blog and then makes contact as he or she have news on the subject which I am then pleased to add.

This is from Frans Loots and sure brings us lots of insider information on South Africas most famous sailing yacht named Voortrekker, my thanks to Frans.


 
Maybe just clarify for readers.

Ketch: Mizzen mast stepped in front of the rudder post.
Yawl: Mizzen mast stepped aft of the rudder post.
 
On Trekker the mizzen was stepped in front of the rudder post. On pictures one would see the helmsman in front of the mizzen and would then assume it was a yawl, not knowing where the rudder stock aft of the mast or about the linkage.


Frans
Morning Roy,
Re the pictures.
The first picture is the original Voortrekker, vd Stadt designed ketch built fot the 1968 OSTAR. Built in Knysna at Thesens. Dr Anton Rupert of Rembrandt Group underwrote the project and thus owned the boat.
After the OSTAR the South African Ocean Racing Trust campaigned the boat for a short while. The boat was then donated to the Navy by Dr Rupert. The mizzen mast was removed and the boat sailed as a rather undercanvassed sloop. Brian Lello, the editor of the now defunct SA Yachting designed a taller sloop rig for the boat. At the same time the navy built a new larger cabin top for the boat. In its first format the rudder was on a linkage system from the cockpit to the rudder shaft. Remember it started life as a ketch. The mizzen was in front of the rudder (ketch). Many folk would look at pictures and say, that was a yawl, not knowing about the linkage.
When the mizzen was removed, the tiller was put straight onto the rudder shaft and the lazarette opened up and turned into a steering well/ cockpit.
Back in 1975/1976 the old mizzen mast hung in the loft of the Navy sailing centre. The old main mast was donated to the merchant navy to be stepped as a mizzen mast for the Howard Davies their sail training vessel. 
Interestingly enough we raced the boat on a windy day in 1976 in table Bay and blew out most of the headsails. They were getting very old and the Navy was in no position to order new sails. Dr  Rupert got to hear about the blown out sails and the Monday morning phoned Bertie personally to give him the go ahead to place an order for new sails. I can remember Bertie coming out of his office. The smile! Dr Rupert was donating it to the boat. That was the nature of Dr Rupert and also the type of person Bertie was. People wanted to support Bertie. He was that kind of man.
Many years later, about 1981, the navy re built the cabin top into what the boat looks like today.
My sources: SA Yachting magazines 1967/ 1968/ 1969, and Bertie Reed who was my Chief in the Navy. I did national service at the sailing centre and Bertie was our Chief so I picked up lots of bits of info from him.


The second picture is the Lavranos deisgned 60 footer Voortrekker 2. In the picture she is sailing with a sugar scoop which made it a 65 footer. As a 60 footer she could be sailed in the OSTAR and races like the BOC Round the world s/handed races. Then for other fully crewed races the scoop was bolted on. This boat was built in-house by the Navy and launched at the end of 1981.


The last picture is the original Voortrekker on launch day. Although built in Knysna the boat was road hauled to Cape Town for the keel to be fitted and to be launched. Launching took place in the Navy dockyard.
There you have it.
Regards,

Frans.
