I like it, will it have a fixed keel ?

I’ve always had great service from the prop shop and their products are second to none

Another pleasure to watch progress Brian !  I learn so much from your builds, thank you for posting.

And me 👍. The colours just make these boats jump out they look great

Had some good weather so took the chance to paint the hull.


I’ve still got to paint the transom which I’ll do once I’ve got the info as to size , shape of the stern trim tab.

Would it not be possible to simulate the pressure by fitting a narrow outlet to the pump outlet. This should create a resistance to flow and therefore back pressure in the delivery. Ideally you would use a machined nozzle with a fine hole but a length of brass or copper tube with the end crushed nearly closed might do. The silicon tube used here however would need replaced as it will just balloon under pressure.

The second trial run with new tyres were carried out successfully in the large park spending about 3 hours.
With these new tyres, the car width has been 1 cm wider reaching 30cm and very stable in steering at a bit higher speed.
This car is a version 3 type by which it has been modified to be much lowered and front-heavier CG for a better crawling performance.    I could have you shown a video, if I recorded it....A working model is to be recorded by the video to report it precisely, isn't it, if possible ?...
The park we have walked is famous for its beautiful rose garden but it was a bit earlier to enjoy the flowers to our regret...
There were very few already open ....

I have just realised that I drove past Prop Shop's premises on our way back from Northumberland a couple of days ago. Luckily, it was less than an hour before we reached home.

You are going to need a MUCH slower motor for that pump.
Your steam engine will consume about 5~15 ml of water per minute and that most likely comes down to less than 30 pistonstrokes per minute.


The engine (assuming you mean the M30 by that) has a displacement lubricator for internal lubrication. refill that one before every run.
External lubrication (rods and shafts) either manual or by wick-oiler.
The pump, just an occasional drop of oil on the moving parts, EXCEPT the plunger. Do NOT oil the plunger.

The only way to simulate boiler pressure is by hooking that feedline up to the boiler, and pressurizing the boiler with a bicycle pump or similar.

Here is a link to the microcosm P71 pump running

Sorry but more questions

• How should I lubricate the engine?
• Any suggestions on how I could simulate boiler pressure, without actually connection to the boiler?
• I will need to work out the rpm the pump needs to run at to make a pully wheel from back of the engine to the pump - any ideas or do I need to by an rpm meter?

Again thank you in anticipation.
