Original Lister Cs Engines / Re: CS Crank Keyway: 14mm not 9/16"
« on: June 16, 2021, 08:23:14 PM »
Thank you sirpedrosa.

Thanks for looking into this. I agree that It makes no sense for Lister to be making a metric keyway in the 1930's given the imperial system was widely used. My engine was built in 1939 based on the serial number information. The only parts on the mine that have metric components (as far as I have seen) are the fuel pumps that have a metric banjo. However, I have seen other folks mention the confusion around the crank keyway and 14mm.  It appears you were able to machine your own keys and fit them accurately using the 9/16" stock you purchased. So at least I have one other person that has done this :) 

I have come to the conclusion that the Keys that I purchased are useless paper weights given how far below 9/16" they are. I placed a new order to get a set from the UK. They are actually 9/16". It may be helpful for those CS owners who are looking to replace their Gib Keys to ask for the measurement of width before purchasing. 

The specifications for tapered key design are clear and a wide gap in the keyway is not acceptable. I have cross checked this across many references including DIN, British and US standards of the past and present.  A key without correct tolerances on the width will be problematic independent of how well the taper is matched. Any forces that arise due to slightest flywheel imbalances will cause the key to come loose unless it was driven in by excessive force which caused deformation to the hub.

Hey Moe

I guess any new Gib keys are mostly ex-India

Certainly excessive force & distortion of the hub is their normal method when it comes to installing.  Have a look at a vid or two lol

Waste Motor Oil / Re: 3/4" needle valve
« on: June 15, 2021, 08:24:39 PM »
Hi Yes, I have a 4 micron filter drum.  But my oil is effectively "new" anyway - I've had no issues to date with blockages

What I have is gearbox oil with no combustion by-products or casual mixing with engine filter bits or brake fluid or whatever - and then diluted a little with diesel as I establish what works & what doesn't.  Its only contaminants are metal particles from gear wear - and I'm hoping that by letting 200-litre drums stand for a few years and then just using the top 80% or so, that these will simply "gravity out".  It seems to be very, very non-hygroscopic - when we drain gearboxes there tends to be a teaspoon or two of "clean" water in the bottom if the water-trap diaphragms have failed; but there doesn't seem to be mixture

I'll bring the feed assembly home this weekend and fit that valve below the existing isolating valve.  I'm keen to see if I can get an improved drip consistency within the limits of temperature/hydraulic pressure etc

Mihit - no, no question.  Just an observation - there had been some conversation around the use of needle valves.  But good-looking ones are expensive - so I'm keen to have a play with this Chinese cheapie

Cheers

I don't think I've measured a key or a keyway in my life!

I Just hand-fit (file and emery paper) and there should be no discenable slop. This goes for everything from high-torque (like large flywheel) applications to fast electric motors.

Mihit, these tapered Gib Keys are potentially different to what you might see in motors & drives?  In that they aren't held "down" by a grub screw but by the taper.  So some of the "fit" is in the force needed to hammer them home until they are "tight enough"  If you watch a vid or two of the Indian blokes assembling them with a big whack from a big sledgehammer - you'll see what I mean.  It wouldn't surprise me if they are expanding in two dimensions under that force

Just a thought.  Cheers

Waste Motor Oil / 3/4" needle valve

See pics?

I have been looking at needle valves and they're not cheap

But gravity-feed isn't demanding and so a cheap Chinese one might do the trick?

I attach a link - should be easy to google

Nice find. I'm still looking for a good CS.

What are you wanting the groovy startomatic flywheels for? You driving stuff?

They're a bit heavier and should smooth out starting loads.  Yes, got a couple genset heads I'd like to drive one day

Whereabouts are you if you're looking for a CS?

Cheers

Bought this fellow the other day and collected it this morning

Came from the estate of a chap who collected old engines and whose widow was clearing out the shed

Described as a "good runner" - might be true

Prices are funny . . .

I missed out on a not-particularly-good 3/1 a few months back that had sat in a shed and hadn't been run for 20 years - it went for $1500 to some insane person

This one I paid $600 for - which seems fair

If this is OK I should have two good runners, and two dismantled-but-probably-useable units and a bunch of spares

Apart from a set of grooved SOM wheels, I reckon I have all I need

Waste Motor Oil / Re: My new "Roger Sanders" style waste oil burner
« on: May 27, 2021, 08:31:46 PM »
Hi, yes, I am only playing with this because I have a few tonnes off free oil - and can see myself being too decrepit to cut a lot of firewood in a few years

Last year I played with a 30% diesel mix - perhaps less will work?  We'll see

I have just made a new top-plate for the stove with a removeable "element" that has fins hanging down into the hot airstream from burner to flue.  I see myself sitting with my feet up near the stove while a coffee pot simmers & bacon makes frying noises and appetising smells . . .

The shed where I have that burner is 400Ks from where I live - so I'm only there from time to time.  But I hope to have some more play-time with the burner this coming (southern hemisphere) winter

Goals are: refine the drip-feed (possibly a needle valve).  More heat from the top element.  Refine "clean" around the operation - no smoke, no drips, no spills

Regardless of all that detail stuff - there's a great deal of heat energy to be had from not very much fuel.  You can see the attraction

I guess we'll see.  Cheers

I'm not sure there is any cracking of the water to produce/burn hydrogen?  That might be nuclear?  I think we're just talking about a wee smidgen of steam in the combustion chamber to looses/softer the soot?  Cheers

Hey Cseyfert

If you've been looking at waste-oil burners on here - you may have looked at mine?  of course you may not have too

I've been playing with drip-feed - on the basis that I'm not building something you can fire up and head out and leave (and come back to find your shed burnt down) but rather something that you have to tend a little while you're in there doing something else (even if it's only drinking tea and warming your feet by the woodstove)

I've had pretty good results in a low-tech sort of way.  certainly lots of heat to be had . . .

I built about three prototypes out in the open air - to get my head around the process

Since then I have built three iterations of one to bolt onto (and be easily removeable from) my big woodstove.  Apart from anything else, I wondered if a MEAN, open-throttle, chimney-fire-generating burn of the woodstove with dry, hard wood, occasionally, might clean out the accumulated soot from the oil-burning

I have access to several tonnes of clean, new, gear oil with no combustion residues, antifreeze or other contaminants to speak of.  As a 66% oil/34% diesel mix it burns like wildfire in the woodstove

Because I have an off-grid shed, my objective is to not use pumps/injectors/blowers - and hopefully achieve a good result without them

I recently modified the top-plate of my stove with a bunch of fins that hang down into the flame path to try to harvest a bit more heat into the top-plate - hopefully I'll get some trial runs this winter coming

I just have a simple low-head oil feed with an inefficient valve (need a needle valve some time soon) and a small tank only a metre above the burner (if I have to top it up out of a larger container every half-hour or so, I will have no issues with changes in viscosity due to temperature - maybe)

Anyway - see link

I took it at night so you can see the red glow - that's a 5mm wall 125mm diameter steel bend glowing there

Hi Daryl

i hadn't realised you were in the Chathams - great spot

i was hoping you were on the mainland somewhere somewhere and could just come and dismantle the old case and help yourself.  I'm currently about 400 Ks away from where the motor is - but next time I'm there, I'll have a look

However do you know about the spares chap in Australia?

https://www.oldtimerengines.com.au/lister-engine-parts/lister-cs/valve-rocker-and-timing-gear/lister-cs-cam-shaft-assembly.html

See link?  Or google oldtimerengines

Really helpful chap.  Has mailed me all sorts of things

Cheers

Hi Dayle. Yes. For sure. Id just like the flywheels really so well see

I bid $300 a while back on a nice complete 3/1 hadnt been run for a few years (being sold by the widow of a collector of course) and it went for $1500. Jeez

I guess well see lol. Cheers

Hey Daryl whereabouts are you?

I have the entire bottom end of a 3/1 sitting in a paddock here.  I don't see why the cam gear would have any more than superficial rust on it.  I would imagine it's the same as a 5/6/1 - maybe worth looking at?

Get back to me if you like?

Cheers, Mike

I have put in a bid and will chase these along.  I suspect they're worth having just for the couple of pairs of SOM flywheels . . .

I'd be interested in any observations, thanks
