Default Plans And Drawing

I'M wondering if there is a site that plans and drawings can be bought and email to the buyer
I have found a few that seem to be grossly overpriced or the have to sell the casting to (not just the plans)

If you can provide a little more information as to the types of project plans you are interested in, you will get lots of specific answers.

There are many engine plans available for sale, and many can be downloaded for free.

Just about all the traction engines that I know of you can buy just the drawings separate from the castings. Its then your choice to also buy castings, fabricate or cast your own.

In the smaller sizes you could also look at Rudy's tractor, that was covered here a while back, this would also give you a US style engine and is all fabricated. The 1" Minnie can also be made without castings but it may be easier to buy just the flywheel and cylinder for an easy life, thats the engine in my avitar.

Give an indication of size and I can point you in the right direction for drawings.

Around a 3" scale Traction Engine would be good

Hi Nev,
I guess it depends on what you consider grossly overpriced. I have designed parts and made drawings and in the end have many, many hours tied up in the whole affair. I try to get a reasonable amount for them when I sell them. If you have never done anything like that it's hard to realize the time and work involved. I have found that most people who offer drawings are very gracious with their work, either offering them quite reasonably or in a lot of cases for no charge at all.
I don't think I have seen any 'reasonable' drawings for a 3" traction engine, or for that matter any detailed traction engine. Like Jason said you could start with Rudy's engine and scale it up somewhat but a 3" engine would have an entirely different boiler setup.

Given that the current engine I am building has 14 drawings of approx AO size just the copy costs would be around £40GBP and you have to expect the seller to make a living and cover the costs of developing the design I don't think that what they charge is unreasonable.

At 3 " you have quite a choice

The Model the other Australia guy is doing is the 3" Fowler A7 by MJ Engineering, as I said a lot of this can be fabricated so you don't have to buy castings, this is his photobucket album with some pics of the engine. and this will show what a near complete engine involves just mine is 2". Plans, construction manual and castings available from http://www.mjeng.co.uk/ They also do a Wallis in 3"

You could also look at the 3" or 4" Little Samson, the 4" is not much larger than the 3" Fowler
http://www.littlesamson.co.uk/ I strongly suggest getting Edwards book if its your first traction engine

Bridport do the Plastow designs though the drawings can be a bit hard to follow
http://www.bridporttractionengines.co.uk/index.php

LSM do the 3" Marshall
http://www.livesteammodels.co.uk/Home.html

The 3" Maclaren is a nice compound engine, contact Terry at Double B Design
double_b_designs@btopenworld.com

Con'd

If you prefer a US style engine then try New West Live Steam
http://www.newwestlivesteam.com/noflash.htm

Jon Rex does a doubled up version of the popular Alchin which builds into a nice model
http://www.miniaturesteam.com/Tracti...n_engines.html

You can also treble up the 1" minnie design, as this is a freelance engine you can do things as you want to some extent and incorporate dits of different engines that take your fancy.

There are a few others but may be problems shipping to you.

I would suggest you spend a bit of time looking at posts on a specialist model traction engine Forum, this is the best by far, there are builders of all the engines I mentioned above except possibley NWLS and also several of teh suppliers also post there, go to the miniature section once you sign up.

Not at all, in fact a pittance. I once produced a set of Cad drawings for a Gauge 1 logging locomotive which took around 600 hours and I didn't create the design, all that was done by a chum, my part was to transfer his sketches into working drawings, so imagine how much more time a larger more complex project would consume - 1000s of hours, yet there are always a few who expect the drawings to be free. IMHO many of the drawings we have going back many years were essentially sold for the cost of printing and the designer or draughtsman simply did the work as a contribution to the model engineering world and to accompany the castings being sold. I will agree that there are now quite old (and long ago amortized) design drawings being sold at what IMHO are excessive prices (by the usual suspects) however I also know that some of these older designs are still held in copyright and in a couple of cases a heavy royalty is being paid.
