Roller steam up 

Oh Yes ; Steam roller model well known in Germany

usually just pushing some water through the pipes clears things

There are various websites where you can buy used models, however, the usual way is to build them yourself.

All the way down.

Thanks for the info. The mechanical water pump doesn't seem to be filling the boiler up very well. How can I improve the pumping and is it worth installing a hand water pump?

As far as I know they don't have one fitted as standard

There is a valve on the tender floor that can be seen at 3:45. The pump runs when ever the crankshaft is turning. This has a two outputs one to the boiler one to the bypass valve. When the valve is open water is returned to the tank, when closed it is forced into the boiler.

It is the same but I'm not sure where the valve is on a Minnie. On my engine one turn is fully open but yours will be different.

The check valve has started feeding back, this is usualy because a bit of dirt has become trapped under the ball.

@@DLRTV Thanks for the advice, how do i get the dirt out and get the pump to fill the boiler again?

A syringe with flexible pipe should do it. May I suggest joining a local Model Engineering group. There will probably be someone who owns a MInnie who will be more help than I can.

@@DLRTV thanks for the advice will try that. So basically just flush out the pipes with the syringe and pipe

Oil allows the metal on metal surfaces to move freely and reducing wear significantly.

@@DLRTV Oh yes I see good point.

@@DLRTV And what does the whistle sound like?

@@DLRTV And I like red flywheel on the steam roller! what sort of flywheel is this called? It's solid, it has 3 very small holes in it and I remember there are some flywheels like this that are black too!

@@ericspreviewshow1803 IT doesn't work very well, producing a loud hiss rather than a note

www.maidstone-engineering-supplies.com. or try ebay

Thanks have done that. Can I use high quality house coal aswell?

That will do nicely

I use welsh anthracite beans, it gives a nice hot fire and burns very cleanly. You do need a large firebar spacing for plenty of air to make it burn right.

Thanks for that. Would Welsh coal beans be good to use for my 1 inch traction engine and 3.5 inch loco?

Thanks will try that What coal should I use in a small 3.5 inch loco with a small firebox?

@@DLRTV thanks would the spacing on a 1 inch traction engine and a 3.5 inch loco be wide enough for Welsh steam coal?

@@mattseymour8637 Welsh steam coal won't work in them due to it expanding as it burns. The roller wont burn it at all, the 4 inch engine will tolerate it but it doesn't like it

1.125" bore and 1.5" stroke.

@@DLRTV Please specify in millimeters.

@@sourabhquestionpaper1260 28mm bore and 38mm stroke.

@@DLRTV thank you

Leave the bypass open when you start the engine running to let it clear the air and suck water in, after that it should be fine.

I drive it quite often, it goes to about a dozen rallies a year.

cool!!

Matt Seymour most likely welsh steam coal broken down into smaller peices

@@User76575 What size of coal do you recommend for a 1 inch Minnie traction engine?

Do you find the Russian standard steam coal is good?

@@User76575 do you ever use housecoal or other types?

Matt Seymour house coal should work fine just might not burn as hot

Nope

@@DLRTV pooooooooo yes it is s for sale!

@@1-8-6-8 Still nope.
