Dean, Bill, Arnold, Jeff, Jeff

Thanks for the comments; its been a bit of a journey. Having never done anything like this before I had no idea what the end result would or should be, so my expectations were exceeded with every step of the way. Each little tweak mostly improved things, sometimes it went backwards.

When Dave suggested putting on the extra trolley, just by itself, I fully expected it not to go anywhere so I was as surprised as anybody else when it pulled the load it did.

Bill; I know what you mean by Last of the Summer Wine. It seems to be a bit like that in these model engineering clubs. Is it just we are boomers with a lot of free time or a case that we've slowed down to the point where we are patient enough to spend the time needed to do the job properly. Although Compo would have would have been an unlikely club member.

Now I'm building my own riding trolley and there will be some minor tweaks to the loco, none of which is really relevant to the this forum. Then its on to another project which has yet to be determined.

Anyway I hope you have all enjoyed the virtual ride with me.

Dear - all who have followed this thread and given Pete their support along the way.
I've only just seen all this, though I knew Pete was working on the little engine that Dad started to build all those years ago, in his workshop in the UK. I can recall him talking about running a track around the garden for my children (his grandchildren), when they were quite small. Well, Dad is 90 this year and my girls (and now Pete's children) are all grown up - there are also five great grandchildren and one great grandchild.
I just had to join this forum to say how thrilled I was to read about Pete's efforts to get the little engine running after all this time. Like father, like son, nothing would ever be good enough until it was pretty well perfect. I've now read every page, and I just wanted to say how proud we all are to see 'Harry' finally on the track.
Well done Pete!

Thanks Trish

At least four of the great grand children still have the opportunity to take a ride on "Harry", as not only did "Harry" emigrate to NZ before they were born but they now live in NZ as well. Of course the grand kids also can have a go at driving him.

Pete, I just saw your 'shout' about this being your last post.
I think that your Ride Trolley is also relevant to this build - well, it will have a Welltank Waterpump Motor in it, won't it?

Bogies have arrived from oneinch railroad and are now installed, the well tank, battery box, pump, switch, piping are all installed. It all just needs wring up (today's job). I'm going to look into the cycle computer install as well.

Other than that its ready to go but tomorrow looks like a non starter weather wise.

One minor tweak to the loco. To the plans, the bypass valve for the water pump located on the front of the right hand tank.

The when the bypass is open it provides a path of least resistance to water from the pump on the crosshead so the water goes back into the water tank. When the valve is closed the pump pressure can open the boiler clack and water is pushed into the boiler. So the valve connection to the tank is the bleed back to the tank and not the feed to the pump (if you follow?)

Its a real PITA, especially when the time you need to operate it there's probably plenty else going on and you have to lean forward and grope around trying to adjust it. All the recommendations are to move it into the cab, so today I set about it and removed the tanks and cab (again) and rerouted the pipework through the tank, into the cab and then back into the tank.

There is a space in the cab to the right of the boiler which is ideal for this.

So here it is all done. It would be ideal to have a right angled valve but I reused what I have hence the loop of pipe.

For now I even reused the original pipework at the front of the tank rather than make new so I just included a replacement piece for the old valve.

That's the latest
