Here you go Keith Running with exhaust nozzle #3 and with the wagon cover over the gas cylinder to keep the hot sun off it - 40 deg C max



The other day I tried the original "coal firing" exhaust nozzle in the loco. It worked fine but makes a lot of noise rustling the flames, much like the blower does. It made plenty of steam when running without the blower, and didn't pull out the fire. The exhaust note is the quietest of all nozzles and there is no exhaust plume, as is the case with #3 when the blower is on, There was no plume even when the burner was off, coasting back up the line on the residual steam

#3 Exhaust enhancer exits exactly at the base of the chimney and doesn't make steam. #1 is the correct height and size to make steam

So when are you going to run it on coal?

Had a great run this morning. The loco trots up the tight return loop like a welsh pony, this is normally difficult for a non-geared loco

It looks like a ride on loco in that pic.

So when you going to coal fire it!?

Great photo Dave, I love it.
The line there looks a brilliant spot for more photos...

Here's the video clip that goes with the still. I put these on my fb story to give my non-steamie mates a wink

Thanks Rod! It's a great spot for viewing returning trains:

The display case was delivered this morning. After a 4 year build a display case is a must! I've used this company many times over many years, this is the 7th one I've had. They do a really good job. I always go for the same style

Test fitting. Need a longer piece of track
The intended home
Happy customer

That is a great display case Dave, no frame to get in the way of the view. Very clean and crisp looking.

A fine collection of locos.

I hope the shelf is not the final resting place for the Hunslet though!

Certainly not! But it has released a nice bit of room from the workbench and is now safe from knocks and swarf

The final aesthetic, replacing the clear silicone water tubes with black coloured

A beautiful finished product Dave. Thanks for sharing the journey with us mere mortals who can only dream!

That final picture shows what clean, solid work you've done on this engine. That is true industrial art.

Thank you Keith!

Tom, before the forum goes *poof*, yesterday I ran the loco on coal

I had to come up a method of keeping the grate and pan in position
Ashpan knob below the buffer beam
First dump

I hope you enjoyed the smell!

Did you film the run?

Fantastic bit of engineering there Dave. Well done...Brilliant.

Thank you lads! The smell was lovely! No filming yet, it was very stop and start, building up pressure, and running low on steam. Not helped by pumping too much into the boiler - the crown sheet was well covered Very little ash came through into the pan. I need to learn how to fire it. Not too much ash came into the smokebox either, I may need more blast

Had a great run on the rolling road yesterday. It's a good way to observe what's going on. I've downsized the exhaust nozzle from 2.0 to 1.5mm, but I may go further as exhaust is not as effective as blower at my speeds, and it's a shame to run the blower all the time. I'm using coconut based BBQ briquettes as fuel. The first run on the line a few days ago I filled the firebox and then lit with the blowtorch for top down burning. This time I lit individual pieces with the blowtorch and dropped them into the firebox (it's deep) for the first layer on the grate. With this "charcoal" very little suction is needed for them to catch alight and my weak little homemade fan is fine. After a while the blower can take over and this generates a lot of heat. I'm getting ash out of the funnel
Thank you Aussie!
