There it is.......The name of our new paddler many thanks must go to Roderick for the suggestion. :clap2
As soon as my wife and I read the name we loved it.
For those who don't know kananook is a small creek which runs along shore line of Port Phillip Bay Victoria .The mouth of the creek exit's via Frankston boat ramp into the bay .
It seems only too fitting as this is my local creek..... :D
-
It's also a freaky train station where weird things happen! lol I've thought how nice it would be though to take Grebe up Kananook Creek...whistling her little whistle and what not...probably followed by random objects being pelted at me from weirdos but yes it's a very nice creak and I like the little private jetties!
it is a very fitting name, it's an interesting one too has a nice sound to it! Good name Anthony!
-
no complaints from you sean when I start heaving thing's at you! :nah
-
I like the name Anth. It has a good sounds to it,,,
Frankston (that is on the Ringwood side of Melb??, I dont know Melbourne very well. All I know is that there is a Connex announcement that goes Change here for Pakenham, Frankston ...)
Good work Rod for the suggestion though!!
-
Frankston is down towards the mornington penisula....south east
Port Phillip Bay infront and western port bay behind us...check your Melway.... :wink:
-
I will check the Melways soon!! :oops:

P.S KANANOOK GUIDE LINES.
One point I will make clear these are my guide line's to which I am building My paddler this information was passed on to me by a friend.
information is placed here as it is specific to my whole paddler build not "topic". :D
Bucket width will be a maximum of 1/3 the hulls beam.The upper edge of the buckets should be immersed about one-half of their height,
the out side diameter equals roughly the amount of spokes or paddles
eg 6 feet diameter equal 6 spokes with 6 paddles.
the diameter of the paddle wheel roughly equates to the height of the paddle wheel so we have a 6" paddle.
The larger the paddle wheel greater the efficiency.
now this guide line will NOT work scaled down or else you would have
eg 1 foot diameter paddle wheel ,with 1 spoke, 1" high ect :D
Hull & Engine details will be added here later :wink:

It's been a few weeks but progress is slowly been made today the crank shaft was sent off to a specialized machine shop.
The crank is having all bearing surfaces grounded down to give it a smooth trouble free life.
Usually this company grinds engine cranks ect and we all had a laugh when the job card said single cylinder steam engine! it was a first :D
The crank will be finished later this week,so some pictures will be posted,
a few more engine parts are need to be fabricated but atleast it's not too many with christmas coming up it's a mad rush!
-
IT's done,I picked the crank shaft up today!
And it wasn't an easy job ,the workmanship is A1 couldn't pick a fault and I am very pleased except for my wife having another steam engine part in the house...! :D
The next job this week will be maching the bearings once done I'm in the home stretch so to speak.
The cylinder is know complete with a finished bore of 3.1/4 inchs and with the crank ,I will have an engine of 3.1/4 by 6" :D
I will post more picture's of the cylinder and parts later. :wink:
-
Today i picked up some bronze to make new bearings to suit the newly ground shaft,they will be a split bearing with wick oil feed.
The engine bed was painted today gloss black,in anticipation for the bearings and crank.
Weight is becoming a real issue so the boiler structure/cladding exposed to direct radiant heat will be built heaver and other areas of the boiler will be built with lighter gauge materials.to help reduce weight.

Everything had a quick trial fit today. :clap
All the bearings have been machined,just require a little running in :wink:
the cross head still requires some more machining and that rusty piece of steel is just there whilst i fit all the bit's and pieces up.
To give an idea of scale the drill bit you see is 3/4 of an inch,which will be replaced by a pin when fabricated..!
For the minute thing's are progressing well but i very much doubt it will be running before the new year too many projects. :D
cheers anthony

That looks fantastic Anthony, I'm feeling very envious!
I think so far you have one of the more interesting paddler projects...building the boat from the insides out!
I also located a weighbridge today....I just some how have to work out how to take my boat into Frankston to get it weighed. Then I can finally work out displacement and move on a bit!
-
It does look fantastic - I am really jealous of the steam engine - I want one too!!!
I am going to weigh my boat before Christmas and see how heavy it is, then comes a little progression forward (hopefully)
Looking really great Anth!!!

hello all paddleducker's :D
I was able to put some solid hours in on the engine this week and today it's starting to look like a steam engine.
A few set back's it will need re-painting but i new that before i put the first coat on. Oil has a habit of seeping in every little place there fore it had a quick sealing coat of enamel makes painting easier later.
The second major set back was the piston being cast iron and 3 piston ring groves it doesn't take to well to impact hence falling off the work bench fixed that! A new one has been made and thats the end of that subject...!
so we know have a complete engine that know requires the valve gear manufactured and I am still not sure which way I will head..?
slip eccentric or stephensons
Most single cylinder Aussie paddlers used portable steam engines to power them very little of them had adjustable cutoff or direction.
In order to get reverse they had a fixed slip eccentric,by undoing a bolt slipping the eccentric the other way and tightening it up again they had reverse,this was a lot of effort and most of the time they used the current to do the work of turning the boat around.
so once decided we will have a running engine fingers crossed.
a few progress pics

Wow Anthony that looks fantastic!
And I think we need to finish our boats, I was looking at a picture in the local paper and reading an article about Kananook creek having a lack of oxgen and as such growing algae!
Now at the Melbourne zoo they use paddlewheels to churn the water (at amazing speeds) and create oxygen! I have a photo somewhere, I wanted to hijack one you see!
Now we finish our boats, have a few races and on my books we should have put a lot of oxgen back into the water!

Decided to tidy the garage today....but as usual I got side tracked...!
The result of this was the valve gear of the steam engine has been decided.
A compromise between a fixed slip eccentric and stephenson,it's a modified version of walschaerts.This version doesn't give me any adjustment on cutoff (either did a slip eccentric) but will give me forward and reverse at the throw of a lever which is what I want.
Below is a picture of the reversing link that stopped the garage being cleaned.....! :wink:
P.S I hope to start the hull in the next few weeks.I will work between doing the boiler and the hull.The way the weather is it will allow me to either work onone or the other and who knows I may even have her ready for june (doubtful)

Another day out in the shed and the return crank has been made not finished but in place on the crank shaft.
It requires a little dressing up but that can wait. :wink:
Also started to bend up the eccentric rod,which was hard work as I didn't want any twist's in the steel nor did i want the metal to be scared from the forming as I would like this rod to be polished bright.
The previous picture of the reversing link has had it's wear pad machined and will be welded to it later.The bracket for the reversing link was welded and will also be machined later.
I will post more picture once all these pieces are together on the engine.
The hardest thing about this project is making it seem some what original even though it was built in 2006 and not the 1900's .
regards Anthony
-
after many hours of conversation, over the new years break,once again a change of plans,the valve gear that has been started has been made redundant before use.
So the engine will have stephenson's....this willbe interesting as I have never made parts of this size before.
will keep you all posted.
-
it has been a while since my last post so sorry to all who have been following... :oops:
I was able to machine up the eccentrics and they have massive rollerbearings instead of the normal bronze bearings normaly used,
i did this to reduce maintance. :wink:
I had to wait until I had access to larger equipent because of the size of metal being turned and the vibrations caused by the two eccentrics being off centre.
I am happy with the result so far
cheers Anthony

Looking good Anth!
You're going to have a fine boat when she's finished, expecially in the engine department!

G'day all,
after some months of costing and designing once again our original design has been scrapped.
we have shown the design to many but the efforts of keeping it to a unique aussie design is extremely hard when your design is limited to trailer size.
The hardest thing is scale as with the models it has to look correct and the one thing that does not scale down is human physical size.
It's also difficult to have a side wheeler although our design overcame many problems it didn't overcome the problem of a paddle shaft running from one side to the other......many sprockets and chains could over come this but the complexity and maintance would be high!
we have purchased some more engines on the way home from echuca steam rally but alot of work remains on them and the size maybe to large for our needs.
So we are researching some original aussie sternwheelers that once ran along the murry eg captain stuart,melbourne,lady daly,kelpie ect and seeing how they would scale into a paddler.....
cheers Anthony
