I'm building an Envoy class tug with a TVR1A steam engine, after assembling the unit I ran it in for a good two hours on compressed air. During this period you need to give it loads of oil (it was every where). I have since added small oil cups to the crank bearings. The boiler, refillable gas tank, steam valve and lubricator along with a lot of valuable information, were all obtained from Sandy Campbell at ACS Engineering. I have now run this unit on steam for about twenty Min's (one boiler full) with no problems.
The hackworth valve system gives me no problems as I use a Sky Sport Six transmiter (40meg), I use the gear switch to reverse the engine.
The tug has not sailed yet as I am now putting the finishing touches, some electronic gizmo's from action electronics to control flashing mast top nav lights (slow on slow of flash), wheel house and engine room lights, along with some other lights to show though lower deck port holes and an electronic steam horn (cheaper than steam and easy). Will keep you updated if you require.
Hello! I'm new here and will be building a Graham TVR1A from a kit too. I was wondering how you added the oil cups to the crank bearings?
Do you have any pictures? Are these cups custom made of available for sale?
