Will you still make a cap for the filler?

Here you are Lorenz, a chunky filler cap.

At last we had a break from the rain and I was able to test the cooling fans for the first time in use.  The fans appear to be effective.  After the run, (the tankful was consumed after 17 minutes) fans were left running for a while, and the cylinder head was just warm.  The bonnet / hood rattled at times.  From analysis after the run, I found that the motor was running 30% too fast, and the loco was doing about 6.5 scale MPH.



Best wishes,
Dave

Hi Dave,

How did you figure out that the engine is running 30% to fast?

Thank you guys.

Lorenz, I timed the axle speed on video play back.

---

A while ago I bought a small LED torch/Flashlight on eBay.  I thought I'd use it for the headlight, but it was rather small.  I've just finished converting it to use as the rear light for shunting and reverse running.

Here's what I bought:


I'm just using the LED, reflector, and bezel.  This was a single AA cell torch.  Interestingly there is a small PCBA that steps up the voltage to 3.7 V.  I'm not going to use it as I'll be using the blowers 12 V supply with another step down module.





This light is very bright, and a cold white.  But it responds well to the PWM dimmer.  The wiring still needs arranging.



Best wishes,
Dave.

Finally I have started painting.  I bought a bench top convection oven, on special offer, to bake the paint after initial drying.  The setting I'm using is 90 deg C for one hour.  The paint is coming out nice and hard.





Because I'm not using a undercoat, the red is coming out quite a nice dark shade.

Best wishes,
Dave.

Update from July 12th
-------------------------

I've finished the bonnet, and cab.  The electrics are all reassembled.  I'm putting all the various bits and pieces all over the place, I've got some shelves.



I like the brass / red contrast



I've just removed the footplate for painting, it's going to be black.

Best wishes,
Dave

Update from July 20th
-------------------------

I've started to dismantle and paint the chassis one side frame at a time so as not to disturb everything too much.  I'm only going to paint the outside of the frames.  First thing is to fill all those excess holes that were used in the earlier set-ups.  I've used small slices of 1/8" K&S brass bar to fill the holes and slots, soft soldering over them and smoothing it off.





Best wishes,
Dave.

Here's the reassembled chassis on the surface plate for quartering of the cranks.

Welcome back to CGT Lorenz!  I think all the painting is finished now.  Reassembly is fun, I've got the footplate back on now.  There's some adjustments to make due to the layer of paint on the cranks.

Best wishes,
Dave.

Hi Dave,

Will you do some lining or lettering too?

Ooh no, a nameplate would be nice though.

It is finished! 

This project was started in the latter part of 2012.  With the test chassis running in early 2013.





The basic dimensions of the loco are:
340 mm long (over the couplings) x 150 mm wide x 240 mm high from rail head to top of exhaust stack.  Weight: over 5 Kg

Best wishes,
Dave

Congratulations Dave. A real beauty. The red colour looks nice.

What next? Any ideas? Maybe an engine shed or a refueling station.

Thank you Lorenz.

My next project is to rebuild my diesel outline steam loco...

Here's the box of goodies that weren't used in the final iteration of the loco...



They aren't for sale Wink

Hi Dave,

I've already seen your steam diesel loco. Very interesting and an amazing sound. Why do you wanna rebuild it?

Interesting spare parts box. Reminds me on "I got a part left but it's running" 😆.

Do you have a new video of the Big Red one?

Hi Lorenz,

Click on the "Rebuilding the diesel outline" link above, all the answers are there.

No new videos yet.

Best wishes,
Dave.

Here we are, the first proper run, and on the new track.  Plenty of smoke; the garden was bathed in the sweet aroma of castor oil.  Most of the run was in first gear, but the last bit was in second.



Best wishes,
Dave

Hi Dave,

Congratulations to your really cool loco. A true piece of engineering. What do your neighbours say to all the fumes, smell and noise? How long can you run with one fuel tank?

Hi Lorenz,

Thank you.  The smoke smells so nice, how could anyone complain.  It's actually quite quiet, the exhaust is very quiet, there's a lot of mechanical noise.  The tank lasts about 15 minutes, but I was topping it up during the run after five or ten minutes.

Best wishes,
Dave
