Diesel Outline...
Re: Diesel Outline...
It’s so confusing Dave. On the forum it shows, Fri Nov 02, 2018 8:56 pm. I posted my reply to you at,Fri Nov 02, 2018 7:54 am…Only 1 hour difference mate…
You are 24 hours in front of us up here in the Northern Hemisphere aren’t you…?
Anyway back to your loco. Are you thinking of R/C Dave. It looks a bit tight under there. But I’am sure ge_rik could help with that. Or may be your quite capable yourself.

Re: Diesel Outline...
The front looks like your best bet but you might have to make your own tank unless an Accucraft one might fit?

Re: Diesel Outline...
Here's the original gas tank, a converted steam boiler. It could be put inside a tank wagon.
Best wishes,

Re: Diesel Outline...
This afternoon I rearranged the gas valve to make it more compact. The dome on the top where the gas is drawn off

Re: Diesel Outline...
That looks better Dave, why do you need such a large gas tank though?

Re: Diesel Outline...
It was a pleasurable repurposing of the boiler Tom. And it works well with not getting too cold with the gas expansion due to its size

Re: Diesel Outline...
Thanks Dave for putting me straight.
So what are your plans for underneath, if any mate.

Re: Diesel Outline...
HI Dave I,m very impressed with your building work and your clever idea's as a newbie to steam loco's I am finding bit interesting seeing idea's put into practice
Well done

Re: Diesel Outline...
A month ago I decided to have another go at fixing the diesel. The lubricator was still unsatisfactory as was the boiler sight glass. So I took the L.C. Mason book - Scale Model Traction Engine Building "featuring minnie" off the shelf and started to build the mechanical lubricator. It is a delightful little mechanism, very little material, but lots of time. There's the lovely click click of the pawls skipping over the ratchet wheel
Here's the lubricator fitted to the chassis running on quiet compressed air

Re: Diesel Outline...
That's lovely Dave
Can you please give us some more details?
for example - how big is the body of this lubricator?
Did you build it exactly as per Mason's book or have you used the book as an inspiration and adapted the design for your needs?
Mason's book (long out of print) is nowadays costing silly money
It was also described in details in vol 135-136 of Model Engineer.

Re: Diesel Outline...
Lovely Dave, runs very smooth. I like the clicking noise as well.
The mechanical lubricator on my 5" gauge loco is of the clutch type which although works well I am concerned longer term it will fail and I will end up with seized cylinders!

Re: Diesel Outline...
Thank you
The tank is 9/16" x 5/8". I built it exactly to the plans. But the 30 tooth ratchet wheel didn't have enough teeth for my application, so I made a 36 and 42 tooth wheel next, the 42 tooth is the one being used, 36 wasn't enough either. So it's 3.5 turns of the wheels to 1 stroke of the pump. The pump delivery is adjustable, it's set to maximum at the moment
I can see myself using these on future models
Best wishes,
Dave

Thanks Tom, it's a lovely project. LBSC would call it watchmakingtom_tom_go wrote: ↑Sun Aug 23, 2020 12:23 pm Lovely Dave, runs very smooth. I like the clicking noise as well.

It's good to be able to see the winding handle going round rather than back and forth

Re: Diesel Outline...
Another brilliant build Dave....

Re: Diesel Outline...
Thank you Dave, for details and all the additional photos and explanations
BTW what solder did you use to secure cylinder cover?
Mason just says "...solder to cylinder..." without elaborating whether silver solder or just soft solder.
I can see this lubricator being very useful in other small models as well - thank you for bringing it to our attention
I have looked at "miniaturising" LBSC's lubricator... but came to the conclusion that it wasn't very practical

Re: Diesel Outline...
Thank you Rod! I call it quiet compressed air So many use those horrid noisy air compressors
Soft solder, same for the bushes and bearings mounted to the tank
Best wishes,
