PS Bellarine

[Doonie]

Hi PD's & well done on the build Doonie   ....but as other members have mentioned 

1. O-rings will slip when driving in the water.....those little segmented V belts will solve this
2. ideal model motor shaft speed can vary from say 100 to to 150 RPM max
3. your tank steering will have the vessel rotating on it's axis length
4. the paddle shafts when rotating I water will deflect from their current point being outboard of the shaft bearings......you could consider mounting a small plummer block outboard of each wheel & mounted on the sponsons

These are available as scale pieces from Small Parts & Bearings in QLD....small to scale & fitted with 316L totally enclosed [ZZ] miniature ball bearings.......I will be using them in my build....here is one fitted to my 5/32" stainless paddle shaft....I also have a 4.0 mm metric version for the auxiliary boiler feed water  pump

Some good thoughts.   Thanks Derek.

1.  I don't doubt you but will try them before changing to belts.

2.   I should be able to attain those revs with the up and downing of the pulley diameters.

 3.   Yes it will be able to do that but the amount of power going to left and right motors is infinitely variable and controllable with the joy sticks.  I want to be able to rotate it in its own length in case I get it stuck some where.   Most of the time it will steam in a straight line with a little bit of left or right to change direction.   If it fails to work  properly, I have a standard esc and servo for the rudder.   Just in case.

4.   Excellent suggestion re the bearings.

Thanks again.

Doonie.

Did not know them until now, but that`s one of the most worthful sites for model builders!!
Thank you DEREK!!
Hope they ship worldwide!!

More done.   Cubbla pics.

...sorry to pinch the thread Doonie........

Gerhard......Small Parts & Bearings are I understand originally US based, but have branched out to Australia & UK via a franchisee system

I cannot see any link to a German franchisee/distributor........but the UK link is closer to you than my link which is 1000 km from Brisbane to Wollongong...... or 20,000 km from Australia to Germany................Derek....

she's coming along verry nice .
i like the looks of her , can almost smell the oil and grease by just looking at the pictures
are there plans of her here on the downloads ?
verry nice steamwinch , where is it from ?
and where are you from Doonie ?
could'nt find it in your profile
greetings from The Bombus

Thank you.   I bought the plan set (2 sheets) from Floataboat.   The plan set is the Bellarine but I am building the Dispatch, or a facsimile of the Dispatch which is the original boat before eventually becoming the Bellarine.   The steam winch is a kit available from Floataboat.   It is not perfect, parts don't fit as the exploded diagram that comes with it suggests but the end result is enough I believe.

I'm from Briagolong, a tiny town in East Gippsland, Victoria, Australia.

Thanks for the comments and interest.

Cheers Doonie.

Got the chimbley nearly done today.

Hi Donnie...

It appears that we share a common interest in the PS Dispatch.

I live at Meningie, SA on the shores of Lake Albert where the PS Dispatch was the first of two paddle steamers, the other being the PS Jupiter, that serviced the town from Milang across Lake Alexandrina. This was one of the early transport routes between Adelaide and Melbourne.

 It is my intention that we will build two models of PS Dispatch, the first, possibly 10-12 metre in length as a playground item for the kids to play on located in our town park on the lake edge.  In the near future we hope to also build a large new visitor/interactive/cultural centre in which I'd like to place two large, accurate models of the two paddlers that meant so much to our town from 1860 to 1930.  If you consider down the track that you wish to sell your Dispatch, our council may be interested in giving it a good home.

I note that you have a number of pics of Dispatch and possibly further information on her, I'd be interesting in obtaining similar for our visitor centre. I also came across an on-line pic of her showing her bow nameplate and that forward "cabin" that you've mentioned.  This cabin was more of a solid canopy or bimini.

PS: Love your youtube extracts, the top edge around the boat side is referred to as the gunwale

Hi Paddleducks.   My head is back in a good space.   It wanders every now and again.   I have started building a 1.2 metre Racing yacht which is now nearing completion and is off getting a couple of jobs done on it.   The Dispatch is back on the work bench.   I have it hooked up to a 6 channel Radio so that I can have a few extra things happening.   Today, with the help of a real nice bloke who lives in this area, I solved several electronic problems.   The boat now operates as follows.   There are two geared 12 v motors, each running one paddle using "O"rings to drive them.   The drive seems OK.   It's not a race boat by any means.   I can't stop the shafts from spinning by squeezing them between my thumb and fingers.   Time will tell, but it will be an easy conversion to belts.   I have the machinery to turn up belt pulleys. Meanwhile, the right hand lever thing on the radio controls the throttle, forward and reverse is up and down.   Left and right on the lever will spin the wheels forwards and backwards at whatever ratio of speed I have on to go from gentle left and right to spin on the spot.   I can also spin on the spot from barely moving to flat out.  I read somewhere that this method is fraught with danger and I can see that it would be if I was a ten year old and did everything flat out.   I have no intention of doing that but I would like to be able to turn her gently in her own length to get out of trouble.   Time will tell there also.
The speed controller is a complicated piece of hardware which works very well doing the above mentioned stuff but has some quirks.   When the throttle is in dead stop, there still seems to be power at the motors because the smoke generator is hooked up to neg pos on the motor and runs freely even though the motor don't turn.   I solved that problem by installing an rc switch so that I can isolate the smoke thingy at the flick of a switch.
Time to get on with painting but first I think I'll plonk it in somewhere to see how it rides with all the rc stuff and the big lead acid battery aboard.
I'll post some pics or a vid when that happens then I'll get back on with the detail work.

Cheers,

Doonie.

Good news Paddleducks.   I plonked her in today.   First, I was gunna put her in my mate's bath cos we don't have one (got two showers though).   Anyway, plonked her in a little puddle just up the road from me and the paddles didn't even touch the water.   We loaded her up with shit out of the back of me mate's car, oil bottles, spanners, heavy things.   Whatever we could find to get the paddles in the water and the boat down near the water line.   Fired her up and away she went.   Doesn't answer the rudder, just sails serenely along wherever it wants to go but the caterpillar system I am using soon sorted that out.   Works perfectly to change direction gently or spin it on the spot to go somewhere else.   The "O"ring drive is perfect.   No slippage, just puddles along noice.   Absolutely no moisture in the hull.   The system of "O"rings I have on the outer side of the paddle drive shafts, with a dot of grease, worked perfectly.   I have a double action radio switch in the electronics to turn the smoke on or off and I will also have lights connected to that switch.
I weighed all the stuff we stuck on it to get it down in the water and I'm gunna need at least six kilos of lead to get her down.   Even with all that extra weight, it just paddles away picking up speed and looks sensational.
I gotta work on the fiddly bits of the superstructure now but I'm not that far off.   I'll post picks when I get it done.

Cheers,

Doonie.
