Hopefully now i have the boiler sorted out the real problem was the the burner wick first time the dia was too small tried another burner with a wick dia of 6mm and it seemed to work except it stopped once after 5mins

Thought i would try out an open framework this time [ Guests cannot view attachments ]

Holding it square was a little of a problem but after the first corner not so bad rest of the pics just to give me an idea [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

P.S. silver soldered still to clean up

Tried some templates today and think i will make a wooden mock up first [ Guests cannot view attachments ]

You will see that model H has a longer bonnet/hood which will really suit my boiler want to increase it to 1 1/8" dia where as Model M seems to have a higher cab [ Guests cannot view attachments ] [ Guests cannot view attachments ]   Size wise frame is 185 x 64mm --1/ 4 x 1/4 x 1/16"  Wheels are 2" Wheel base 5 3/4" don`t know it that will stand as a mini car

Made the mock up out of card instead of wood but there are some things i really need to think about [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Will post pics first [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

You can now see space is going to be a little tight boiler will be made from copper end caps i was going to spin on reflection i think i will just visit the plumb centre and buy a couple if nothing else i at least know the size to make it

Some extra food for thought [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]


Size wise it`s not exactly 100% but not far off
[ Guests cannot view attachments ]

Here you can see another option using larger wheels ( 3 1/2" ) could also make a locomobile .  I think i will start again and make a steam platform even if it`s only an oblong sheet with a wheel at each corner that way the engine could be fitted as you see on the test bed or it could be turned round and fitted side ways belts and pulleys used for transmission although i would prefer to use worm drive so you see i still have many things to think about
P.S.  larger wheel 2 1/2" NOT 3 1/2"

Not sure what to suggest, but really enjoyed the mock-up

Frazer yes twin tube boiler could be used ( some of the French boys have gone down that route ) if i had just stuck to the title i.e. mini steam car i would have been ok  the fact i wanted to make it scale is really the problem and the fact i mentioned Cadillac made things worse at that period no mater which model you choose they seem to be the car with the smallest  bonnet/hood.  For those of you find it hard to make a bonnet have a look at this

Fail Legano A6 paint scorching would be the problem but it lets you see there are hundreds out there let`s wait and see i think i will come up with some thing.  Would be grateful for some info on silver soldering the test boiler i made used up the last of my s.s.rods which were 1.5mm i have since bought 0.5 and 0.7 s.s. wire ( don`t know why maybe price ) and bought the smallish type torch Danny suggested (still to arrive  ) Torch i have too large for sheet metal so any info on that will be helpful. Now i will try and put pen to paper towards the end of the week something will happen

I also love the mock-up, it certainly shows a lot of potential.

Scale is the problem factor I find in many of my builds. When trying to keep something fairly small, you run into all kinds of problems of fit, function and finish. Generally the larger scale you build to, the easier that build will be to accomplish, but then material costs / weight / handling / storage issues start becoming major factors as well.

Somewhere there is the perfect compromise on what scale to use for any given build, but for us mere humans, perfection in anything is most always unachievable!

Frazer many thanks for your input small torch arrived this morning
Stoker what you say is 100% correct this morning i was going to build the Cadillac carriage drew up the frame to cover in 1mm plywood the windows in the doors open up and down just like the old loco doors in the UK railway and not in and out then i stopped to think how would you protect it from the burner flame same with the wheels the smaller the scale the nearer the flame

Scale is a problem ( hate to keep mentioning the French boys they start with the wheel ) i don`t think there are enough days left on the planet for me to make such things that`s why the size came out as it did wheels i had already.
[ Guests cannot view attachments ]
Bought two of these many years ago for the great grand children for the princely sum of £3 and they have just lay unopened on top of a cupboard forgot all about them kids today seem to prefer there smart phones or computer. I think the road i have to go down is to make a steam working platform to iron out the transmission worm drive preferred how many people can tell you the ratio for a 1" or 2" or 3" wheel NONE then there is JIm`s vertical/horizontal drive on a smaller scale would help to find what pulley sizes would be required so you see still many things to think of.  Would be nice to see some of your own builds even failure or otherwise that way we can all learn
Thank you for your input
