It's going very well.
At some point I'll have to build a small engine like this.
Maybe a set of castings from Torsten Schür.

I've only machined flywheels from him, some of the nicest iron I have ever machined. He has some quite nice engines too.

With the engine now proven to run it was time to think about how to mount it, I've done a few on wooded sleds and a few on 4-wheeled carts so for a change I decided to do a 2-wheeled "sack barrow" type similar to what you see the IHC Tom Thumb mounted on.

The wheels seemed the obvious thing to start with. Some ERW tube provided the rims, some 16mm round bar the hubs and some 8mm S275 black bar was cut into circles and the spoke profile milled into them.



They were then silver soldered together after which the hub was bored out to final size which ensures the hole is true and concentric to the rim should anything have moved during soldering.



The axle bolsters were fabricated from some steel angle and rectangular bar, hub retailing collars turned from 16mm bar and the handle bent up from 5mm steel solid bar.



A box was needed for the ignition and battery so some maple wa smachined down to 4mm thick and the mill used to cut the finger joints



Who needs glue with a fit like this

Always nice to see a new engine running Jason.  :ThumbsUp:

I was wondering if you were going to minister to the water hopper logo? As you’re aware that was an early casting from the  Rhuddlan foundry. Some 30+ years ago. Later engines had a new photo etched pattern with the Alyn diamond having a raised border.

The barrow frame will definitely make it look a nice authentic exhibition piece.

For the benefit of our readers what form of ignition have you employed for this project?

 :cheers:  Graham.

Thanks Graham

It was tempting to machine off the cast name plates as there were some areas where the detail was a bit soft but I decided to keep them. There is still some additional "signwriting" to be unveiled, just done the last item - drip fee doiler so should have some photos later in the week.

I have gone with my usual S/S CDI ignition from Roy Sholl. It looks like these will continue to be available as someone new has taken them on as Roy retired. I will use a simple adjustable timing bracket clamped around an extended main bearing and a "peg" on one of the flywheel spokes to male contact with it.

I did also buy one of those spark generators you posted a video of on FB but will try that on something else. Maybe you could do a youtube version of that video to post here?

Thanks for posting this. Who is the manufacturer please? are they currently available? I don't use Facebook, so it would be great if you could ID the unit here. Thanks.  :cheers:

With the woodwork completed and some paint on the metal that is another one finished.

Still needs some tinkering to slow it down, it is making a lot of compression and really has a kick when it fires. Also want to get it picking up faster once the governor latches out.

Marvelous work and quite a fine runner!

Did you make the cylinder oiler or is it off the shelf?

Words fail me at present Jason.  It will take me some time to take in all th nuances….   :ThumbsUp:

As usual your workmanship shows through every detail.

The R.L.E was designed to be an engine simply built by the average machinist but your vision has taken it several levels.
 :cheers: Graham.

Thanks all

The oiler is similar to the one I made for the Robinson, I like the cup shape more than the usual flat brass bottom and straight sided glass.
