Original Lister Cs Engines / Re: hart and lung machine

Isn’t that great 🙂

Y’know, if the piston is most of a mm different in diameter from place to place - it seems to me that if you held a straight-edge along it in various places there would be enough for the straight-edge to “rock” visibly?  Cheers

Listeroid Engines / Re: 6/1 silencing

Veg have you seen the exhaust length/diameter chart in the CS installation manuals?  Someone will be able to reference it for you.  I suspect it might want to be fatter as it gets longer?

Also the various "buried" ones?  Effectively silent

Cheers

Original Lister Cs Engines / Re: Lister CS 6/1 running to slow
« on: August 24, 2020, 08:28:30 AM »
Hey Bob just a couple quick thoughts

Am I right in thinking you’re in Australia?  I have dealt with the Old Timer Engine Spares chap there & he has been very good. A couple times playing with CSs & not being sure about the provenance or performance of injector or pump, I have simply bought a new injector, pump & delivery line from him to eliminate doubt about those items - and have had good results. I figure they are good items to have as spares anyway. Just a thought

I have a Chinese “ST” head been sitting in the shed for several years destined to go on my 6/1 or 8/1 one day. Can you tell me how you flashed it please?

FWIW I put a new piston & rings & re-honed cylinder in my 6/1 yesterday. I assembled the rod/piston/rings to the crank & dropped the barrel down over the studs & held it suspended 140mm above the block with a bit of dressed “6X2” and rotated the crank to lift the piston up into the barrel - compressing the rings with fingers & ascrewdriver & exploiting the chamfer on the bottom of the cylinder to lead them in. IMHO SO much easier than from the top if you don’t have a ring- compressor.

Just a comment. Cheers

Yeah, I'd be happy with half, that.  If I was putting 2kW into my batteries there's be something wrong lol

I need enough battery and enough inverter to run an efficient fridge & a few LEDs at the same time - that's it really

Where I was at with the Leece Neville alternators is that I hope they will be robust and over-built

Yesterday I took them of the tacked-up mounting frame and welded it fully.  Now, of course, with the minor distortions of welding I'll have to "tweak" stuff to get the two pulleys perfectly in the same plane

No hurry,  The engine concerned is sitting 400Ks away with the barrel off and the piston is down here lol

One thing at a time . . .

Hi Mike

These are truck/bus units

Think of the diesel driving it as probably having a working RPM range circa 1200-3000

Even with a big gearing, I suspect that 8000RPM figure is the safe max for the units and their normal operating speed is probably truck RPMs X 2-ish.  I suspect their output is probably good at 5000 RPM

Guess we'll see.  Thanks for the thoughts

Lister Based Generators / Two X big 105A alternators on the Lister CS
« on: August 12, 2020, 09:32:52 AM »
Hi guys

I have a kinda hybrid CS6/8 here which I'd like to use to drive a couple of big Leece-Neville truck alternators to charge a bunch of 12V batteries (Yes, I know the 12V has many limitations, but it's a legacy system with a single large-ish 12V panel and three small 12V inverters and a bunch of batteries - so it's a "use what you got" system)

I forget what I paid for the two alternators - it might have been $40, or maybe $40 each?  They were new-old-stock, still in their boxes and packaging.

See pics?  I have the two of them on a base I can weld above one flywheel of the CS and put a flat-surfaced idler between and below them (adjustable in a couple planes) to use as a tensioner

The alternators have straight-blade fans (not fitted atm - I just have pulleys on for alignment purposes) and info on line says they don't care which direction they rotate at

I don't have a lot of info on them other than what I find on line; but I think their max RPMs are 8000.  So with a 600mm CS flywheel and a driven pulley around 70mm, even at 600 revs they're gonna be fine

I'd appreciate any experience-based thoughts on mounting/belts etc.  The grooves are for an SPB belt, but will drive just fine with a B

See pics?  How do you reckon I need to wire the buggers?

One pic shows a label with the + and the - and the instruction "observe polarity" and the = and - terminals on the casting at the other ends from those on the sign.  I suspect the label may be generic

I have no idea at all what the various other small terminals are for.  Possibly I can ignore most of them

The brief, generic guidelines on several Leece Neville installation blurbs say the installation needs a switch/key in the circuit and also a 6W bulb (so there's a wee current for excitation, perhaps?)

Expertise welcome :)

Alan if you search for Lister CS electric start - here or Google - you will see several vids that are simple & good. They are always an option if you aren’t confident with the starting components of your SOM and don’t care about keeping it original

Yes. Doesn’t like the wind. Seems to not make any smoke at all on a still day when the oil/air is consistent. Check out pic/vid of flue against the gum trees & the sky on a calm day

Waste Motor Oil / Waste oil burner Mk11 prototype working reliably-ish
« on: August 01, 2020, 03:36:27 AM »
See 30-sec video YouTube link if anyone is interested

https://www.youtube.com/watch?v=JrPAqyuBNcI

This is a Mk2 version of the prototype and it seems to do the things I'd like it to do:

Burn clean-ish and consistently with no energy input other than oil.  Start and run pretty much without smell or fumes.  Put out lots of heat and provide a "cook-top" with hotter and cooler surface areas.  Use a reasonable amount of oil

Pictures & short video tell the story, really

It burned 1.2 litres of oil in an hour and eight minutes.  I got it warmed-up, filled the little oil reservoir, set the flow to a pencil-lead sort of cross-section, set the timer on the phone and wandered off to do some other work.  It ran steadily and consistently for an hour and eight minutes without any intervention from me

I have made the "up-draft" burn chamber thingie with a 100mm BSPTM thread on top so it can just come off to be tinkered with

The flue thingie is on a flange so I can change it at will.  I put in a TEE with an 80mm drain bung on the bottom to facilitate cleaning.  It's 100mm flue atm - I'd anticipate going to conventional 6"/150mm flue sections if it works well-enough to end up in the shed

My observation, fwiw, is that this thing and its ilk are basically just one big draft/flue - it doesn't like interruptions such as a baffle I trial-fitted; but I have been starting it by tipping in about half a coffee-mug of a 50/50 diesel/petrol mix & lighting it with the butane torch.  It lights with a bit of a "whump" and the expanding gases shoot through and up and out the chimney with an immediate "roar" and it establishes a solid draft which continues as I turn on the oil a couple of minutes later; and it just burns happily away

Next step is to try it on various dilutions of the heavy oil of which I have tonnes - and then tinker with a Mk3 that might look a bit "nicer".  Might

Cheers

Other Slow Speed Diesels / Bryce injectors
« on: July 29, 2020, 01:11:25 AM »
INJECTORS

Because some of the older big machines such as Blackstone/Miirlees have fallen under the “Lister” label in recent decades – I might just put these in “Lister” and in “Other”

I wonder if someone has a use for them?

I have four large Bryce/Lucas-Bryce NTDOB injectors – complete and still sealed in plastic-wrap and original boxes from what looks like a factory overhaul.  They were part of a larger auction and I would say they have originally been “spares” inventory somewhere like a municipality or a hospital where a large Polar engine or something like that has been working

I would guess the pictures tell the story, really?

Perhaps these would be useful to someone restoring or working an older large machine – I think this NTDOB (and possibly related/possible overlap NTCLB and NTDLB) series of injectors are from large individual-cylinder two-stroke diesels – but I stand to be corrected

It also seemed to me that injectors such as these in good condition might represent an opportunity for someone to machine an adaptor-sleeve to use them in a non-original application?

Stamped into the injector is the Bryce code:
“BRYCE WZ NTDOB175HO464

The boxes say “99-5367-7241” and that’s a coding number for parts that have had a military application in some way – perhaps a marine engine or a large generator/power plant?

99-5367-7241 is an American NSN (National Stock Number) in Federal Supply Group (FSG) 28, and Federal Supply Class (FSC) 2815 & FSC 2910
NSN listing part number 99-357 also references a listing #U1614

99-5367-7241 is also on the NATO Parts list in categories DRN2910 & DRN4780 as: part #2815-99-536-7241 “Injector assy F” also mentioning parts numbers OD28674 and K8098

In Britain they’re referenced with part # “8715” which is a Defence and Aerospace listing under the UK NIIN (National Item Identification Number) 995367241
UK NIN also references part numbers OD28674, 2815995367241 and 995362741

Bryce says applications include Miirlees Blackstone and Lister Blackstone engine-type ERS MGR two-stroke diesels and Wichmann AX engine-type diesels

I’d be relaxed about mailing these anywhere they may be needed.  I guess each box might weigh two or three KGs?

I guess anyone interested could message me?  Cheers

Waste Motor Oil / Re: waste oil burner "ozzirt" type. Works well
« on: July 12, 2020, 06:19:36 AM »
Okey-dokey

I realise this isn't a subject in which there's a lot of interest - so my apologies to anyone who feels his time is wasted by it.  But it's only really my time wasted

There are lots of simple draft-type burners around and they're capable of immense heat, limited only by one's personal courage, as far as I can see

I must have watched 50 or 100 YouTube vids of burners ranging from awful to unbelievably efficient-but-complex.  So a while back I posted some pics and a short video or two of my iteration of an "Ozzirt" type drip-feed burner - it was just proof-of-concept, really, but I was encouraged by the fact it would respond to "tuning" the air intake at bottom, midpoint and top (primary, secondary & tertiary burns - if you like) and the fact that was repeatable.  Plus it was easy to have it burn "clean" - at least in terms of exhaust output

So I'm 2/3 of the way of building Mk11 as mentioned a couple of weeks ago.  See pics attached?

It's still rough, still proof-of-concept.  I wanted to see if the Ozzirt drip-feed design would burn through a big chamber and around a baffle - to capture and dissipate a chunk of the heat - and also if it would do that with a "cook-top" top section which, in an ideal world, would incorporate sections that were "hot", "bloody hot" and "simmer"

So here's some ugly cut-and-shut construction.  It's a hunk of 300mm (12-inch nominal bore) pipe with a 12mm (1/2 inch) wall - should accumulate a bit of heat with a bit of luck) and the top is made out of some scraps of 12mm flat too

There's a base (not shown cos I forgot) which incorporates a stand etc . . ,

The intake/burner bowl/burner tube is a re-use of the one in the previous post - but I welded a section of 100mm BSPT male thread onto it and welded a 100mm BSP socket onto the bottom of the intake part of the big "stove" chamber - so the burner tube and air intakes assembly hangs off the elbow shown and is removable to play with as long as the thread lasts (not long I suspect)

At the exhaust end of the stove chamber thingie there's a 125mm flange welded in place two-hole-square, so I can attach whatever I like to it, flue-wise, simply by building it on the end of a suitable flange with two-holes-square orientation

Like any piece of amateur cut-and-shut, it's ugly - although it'll clean up with some weld-grinding.  Basically I tacked stuff together, heated it with the gas to bash into shape in the join areas and filled the gaps with weld,  It'll work well-enough to prove/disprove the concept

My aim is to have a "stove-type" burner which is safe-enough to put in my shed and which will radiate a chunk of heat and which has a "cook top" function.  So this is a first step towards that.  I wouldn't anticipate building anything that one would leave burning unattended

The base (not shown cos I forgot to photograph) incorporates a steel "tank" for want of a better word, made from 8mm plate, and with 40mm BSP sockets at each side - because I'd like to see if there's a safe way to "pre-heat" the heavy oil of which i have several tonnes available

So there we are.  Excuse long-windedness
