Paddlewheels

mmmmmmmmmmm........PD's....sort of what I was eluding to Stuart.........a length of 1.0 mm brass wire & a 12BA die nut .....only problem here in OZ is that we cannot purchase 1.0 mm diameter brass rod.....

We are still imperial with 0.03125" diameter wire = 1.23 mm diameter ............

I like 10 BA...as that is close to 1/16" diameter........... Derek

Hi All,
Many thanks for the replies Stuart & Derek.
Stuart - I had never heard of a Capstain lathe before, allways learning

I think i will probably go with your idea of threaded rod ends.

Derek your spot on with the size to cost ratio
I have some time to give to this project tomorrow so hopefully i might have an idea re cost of etching which is the the make or break costing - fingers crossed their costing methods are sympathetic to model paddle boat makers

I have three complete sets of design drawings all in 1:24 and 1:48 scales prepared and still trying to sort the maths for reduction / enlargement for 1:32nd
Might get this project off the ground soon will know more tomorrow.
Many thanks again
Kim

Hi all.
Today i received a costing from one of the larger photo etching companies and in the amounts I'm looking for their price puts commercial production out the window.
Not put off i widened my search and have found a very enthusiastic engraver just down the road and i have an appointment with a local photo etcher on Tuesday.
Will keep you posted,
Kim

Keep trying Kim, I'm following your exploits with interest!

Sorry PD's....I stand corrected ....[only problem here in OZ is that we cannot purchase 1.0 mm diameter brass rod] = incorrect...all good model stores sell the K&S range of metal sections & sheet....... from USA - naturally 1.0 mm brass round section is available

If you do go down the path of attempting to thread the 1.0 mm diameter brass, you will need the appropriate sized 3 jaw pin vice, the die nut & best to secure the pin vice truly vertical in a larger bench vise...see my mock ups for 10BA = ~~~~~~~~1.6 mm diameter

Brass or bronze material technically does not need any tapping or threading paste......... ...however on such small section material [1.0 mm diameter] any additional lubricity wetting agent will help & minimise the potential to shear the material...... ..... but ....

I would shear 1 in 10 small 10 BA studs that I attempt to thread ....... as you can see I am firstly using a die [with the split] which provides the highest tolerancing major diameter as I do not constrain the die which would effectively produce a thread form with a smaller major diameter  

If you searched the extensive posts here you may find that 'bogstandard' recommended "Trefolex" green cutting paste [for small brass diameters] ...however I suspect that kitchen olive oil or automotive mineral oil may suffice

.....& just remember the old teaching.....1/4 of a turn clockwise.......then 1/8 of a turn anticlockwise.................this is to 'break' the chips being formed ....... ....Derek

Hi All,
Many thanks to all that have input on this thread it has been a great help.

I have now sourced suppliers for all the components to make the wheels complete with drive shafts.

1mm Brass rims
1mm Brass Floats
12ba Brass fixings
6mm silversteel rod

The first set of wheels to be produced will be the 1:24 rimless feathering wheels and allowing a very slim margin should have a retail price of £149.99.

I'm pretty sure i have done the best i can to keep the cost as low as possible.
Your feedback on the cost or materials would be most helpfull.
Many thanks again,
Kim

I found this on one of my many trawls for information may be of use to someone -

Lets be honest, it isn't cheap, but having said that it's a LOT better than I thought it would be!!

I bought a set of the 1:48 paddlewheels that Mike Mayhew makes at Waverley Models, and they were over £160 5 years ago! So 1:24 at £149.99 is nothing short of amazing when you consider how much metals have risen in price over the last couple of years alone!

I would like to build a paddletug to use for tug towing - Simply because I've never seen one used in competition before.... So I'd certainly be interested in a set of rimmed wheels at 1:32 scale.

Please post photos as soon as you get the first set produced Kim, I'm sure it would whet the appetite of a few of our members!

Yep it is a lot better than i had imagined it to be!

Perhaps my margin is to slim

Did you have a tug in mind Eddy?
I'm Considering building an Old trafford / Reliant.
This is a project long overdue as my Dad built a plug for her  when i was about ten after a visit to the Maritime Museum.
 

Please post photos as soon as you get the first set produced Kim, I'm sure it would whet the appetite of a few of our members!

As soon as i have the first batch i will post some pics.

Going off topic a bit, but in answer to your question Kim, I think maybe the tug "Lingdale" which worked on the Tees.

Hi All,

A quick post to round this thread off.
First of all a Huge thanks to all that have voted, given advice & support.

I have started to put together the first wheel in our range and have to say that I'm very happy with the results.

The final component  (the hub) will be with me on Monday and kits will be available for dispatch thereafter.

Another thank you has to go to Barry for allowing me to stock his range of paddle wheel kits. I believe this now gives me an extensive range, if not the widest available.

I hope to grow the range over time and also include hulls of some of the well known Steamers of the Clyde.
Again,
Thank You All
Kim

Hi,
you sure you have right price for Barries paddlewheels
sturt standard is one pound more than the deluxe
kiwi

.... If it was easy everyone would be doing it....

A mentor once gave me this piece of advise ... not until i started Clyde Model Boats just over a year ago did i fully understand it !

I have had a most interesting year since starting this post and have to thank a lot of people for their help, support and advise in particular i have to thank Eddy  & Stuart who have both given encouragement and technical support... To both of you a big thanks!

So looking forward to next year..

I will be continuing with Paddlers ... just because i love them! However i have to face up to the fact that it is a business i am running and again , as my mentor kept telling me ... the only reason a business exists is to make a profit... so with this in mind i have decided to branch out into Turbine Steamers. Again they are a niche market but offer model boat builders an alternative to what is currently available in the market place.

One of the biggest compliments I feel i have received this year is an invite to display at the Mobile Marine Models Christmas Cracker Event  - 4th December 2010 ... If you plan to go to the event please do come say hello.

So here's to next year !

Thank you all again and my sincere thanks to all that have helped to get Clyde Model Boats to this stage!
Kim
