I ran my 3" Ritalea river launch today with the Graham Ind single cylinder engine it. I have been playing with props, gas jets etc to get it going to its best potential. I keep increasing the prop size and blade area and it just loves it, today I thought it was going to get up and plane if I had not throttled it back! This was on 30psi so I turned the gas down and it ran well all day on 15 to 20psi. After seeing how well the single goes I dont know if I will bother with the twin, might just get another single and run it with a reversable prop so the engine is always running forward. Cheers, Ian

 :-)Don't know if I have it right but thought that the little clamp on top of the steam chest actually compressed the "0" ring and hence seal the slide valve rod.

Hello Gents,

I am assembling the TVR1A and ran into the binding linkage problem with the bushings filed flush. I was inquiring and got directed to this thread.

Is the overall opinion that we must simply use Loctite and hope for the best?

I was thinking that replacing the filed bushings with another set of un-worked bushings could solve the issue as the extended portion would allow the screw to seat and be tight, whilst the linkage pivoted on the bushing.

Hi Tom,
I'm using Loctite.
Just a Small amount (Use a toothpick) on the various screws.
This also makes it easier for you to undo them later on.

Going back to post #5, the bush should not pivot inside the Alluminininium linkage. Technically, the screw should have a plain part that the bush pivots on.

Mr. Graham answered my e-mail overnight, and this is what he said:

There is usually a little bit of binding initially. What I usually do is snug the bushing slightly, put a drop of oil in between the parts that are moving so that the oil runs into the sliding surfaces and then rotate the part in the direction that keeps the screw tight. I do this a couple of times and it usually works out.

I performed this operation tonight and it worked a treat, a real treat! Two or three revolutions and the links freed up completely. 

Cheers,
-Tom

Gentlemen, I have all of the engines that they produce and had only one that gave me trouble and Mr Graham made good on the replacement parts.  By the way this happend 6 months after I received the engine.
