Coal fired vertical boiler loco
Well, following the article in the recent SMT, i have decided to make a coal fired vertical boiler loco.
Its going to use a couple of old mamod cylinder that i have spare.

i thought you would mention the cylinders (because they are mamods right)mhlr wrote:I thought you were gunna use Wilesco cylinders?
Because i have two mamod cylinders spare, and they are smaller than wilescos, also can change directrion with a lever, not by pushing it.
This is a diffrent design, which is smaller than the previous one

Having read the comments on the 16mm e-group, about the run-time, etc... I am thinking that with two cylinders the water comsumption rises considerably, you'd forever have the top-up bottle in your hand, because you'd want a lap from it atleast, the amount of water you'd be pumping in would cool the boiler=no steam=no blower=back to the electric blower=fail.
Go for the single cylinder, it's proven it'll work.

Looking at the size of the boiler and the inefficiency of the firebox, I would have thought it would struggle to supply the double acting cylinders with enough steam, especially the extra resistance from the upgraded cylinders with the much stiffer springs and o rings.
Maybe a little twin cylinder made from regular single acting ossies would work better? especially as it'd be suitably geared down and used with the grooved 'extra power' cylinders.

Do I get the impression a mixture of enthusiasm and sheer bloody mindedness may be overpowering engineering ability and quite possibly common sense here?
Or maybe I'm just cynical.
Either way, it's an interesting project and I shall be watching carefully.

i did read it properley
you said "No matter what burner you put in it, it still won't be able to cope with the steam supply."
To me, that sounds like your assuming that no burner at all can supply enough steam.
And ok, i will use ONE cylinder, even tho i dont really want to, and it doesnt look as good.

Because from what you wrote about changing the burner implied that a change in burner would improve the possibility of a steady steam supply.andysleigh wrote:you said "No matter what burner you put in it, it still won't be able to cope with the steam supply."
