Osmotor using Mamod Cylinders
Osmotor using Mamod Cylinders
Has anyone built an Osmotor type device using mamod cylinders, or has any one seen a plan for such a device?
If at first you don't succeed, use a bigger hammer!

After recent comments on the forum about Ozmotors I had wondered if this was a possibility. I think the main problem would be making it narrow enough to fit between the frames for 32mm gauge. I think a home made port block is the answer but I have not yet measured it up. I am sure someone somewhere must have made one.

Sorry, it isn't the port block that is the problem it's the bit from which the steam goes into them, which in a mamod loco is the reverser block. That would need to be narrowed down. Mamod do a twin cylinder marine motor which gives some idea of how an osmotor using standard components would look.robc_wa:116636 wrote:After recent comments on the forum about Ozmotors I had wondered if this was a possibility.

For railway usage the power take of gear would obviously be between the cylinders

Have a look at Dave Watkins' drawings for "brick"

Hi Jim,
I designed and a friend made an Osmotor type steam motor using a pair of Mamod cylinders. The engine is fitted to one of the bogies of a model of Monarch which is now at the W&L. The model is G1 there isn't enough room for a pair of Mamod cylinders between the wheels in '0' gauge. The model of Monarch isn't finished but it has had a test run when it worked really well. I don't have any photographs but if any one is interested I could take some when I see the chassis again in a couple of weeks time.
Below are two photographs of one of my steam motors fitted to a '0' gauge test chassis. They work OK but really are a bit small and have to be quite well made to work well.
Regards Tony.
