Other Slow Speed Diesels / check out the exhaust note on this beauty
« on: January 13, 2019, 06:13:32 AM »

There's a Polar engine a lot like this in an old generating plant in town here, but it just has all the exhausts into a single stack & doesn't sound as good IMHO


Here's one out of the box - check it out

I would guess some poor chap has bought this figuring it'll run his house "of grid" and then gotten disillusioned with the project maybe?

Check out the chain drive!

Someone has spent a chunk of time & money on this at some point - possibly around 1940 for the original build, then later with a stainless tank etc

It seems to have something called an (Admiralty Patented) Dial Slow Motion Quick Wave Changer

The area it comes from is one of NZ's remotest parts and I suspect this may have been a "state of the art" lighting plant and a big step forward from the kerosene lanterns for some family living several days' horseback travel from the nearest civilisation "back in the day"

Maybe the "LEGTROFLATER" Black & Decker bit was 220 VDC - an output of 2.75A - and the Dial Slow Motion thingie made AC?

Possibly more use in our Museum of Transport & Technology than in actual use; but what an interesting slice of history

Possibly a little over-priced

Lister Market Place (things for Sale) / check this dude out

Second or third time he has listed them.  The first couple of times there were lots of comments like "man, I've got two of these I paid $600 for" and "what say I sell you my three old ones for $5000 each & you give them a coat of paint and sell them for $10,000 . . . " but I guess folks got tired of the sport

No takers yet

This is the CS of which I spoke


Sold for $1500 in the end

Original Lister Cs Engines / Four old CSs sold

Just a note of potential interest

I always think what someone will pay at auction is the real indicator of value of an item - regardless of red herrings such as the "asking" price of similar items or the seller's aspirations or illusions

So some chap here just sold four old CS in various states at "$1 reserve" actions.

These are the results:

Will be fascinated to watch this auction - he has maybe four CSs all on a $1 reserve auction

I always think a cash-sale auction is the way to gauge the ACTUAL value of an object as opposed to the percieved value

Will watch with interest

General Discussion / Inverters
« on: July 31, 2018, 08:47:42 AM »

Hi Guys

I know folks on here love to share their experience, and I'm interested in improving my thinking on inverters . . .

Firstly let me say I have been re-reading Starfire's excellent post and subsequent responses.  See link below:


I'm a big KISS fan.  I used to enjoy having cars with points ignitions and carburettors cos I could see how everything worked and diagnose a fault in 5 mins flat - but I have gotten over that particular Ludditery and these days have a couple of $1000 2.2-litre Toyota Camrys as they are the philosophical equivalent and may well outlast me

I'd like to own an inverter like the Camry - tough, simple, good, over-engineered and under-stressed . . .

The gentleman who has been advising me on solar stuff - and whose advice I have found to be good - suggests that the modern combination of inverter & charge controllers are the "way to go"

He is recommending this unit:


But I could just as easily buy whatever I can find that is a super-robust charge-controller and do things like managing charging/voltage myself, and maybe run two or three small inverters

Typically my households use bugger-all current as I tend not to have anything with an electric element apart from an electric blanket and a small toaster.  My norm/current setup is: solar hot water, woodstove, wetback, gas hob, low-output microwave, spring-fed water so no pumps etc etc - a familiar picture I am sure

I am attracted to the Outback inverters

I have a couple of 230V gen heads as works-in-progress and hope to be in a situation where one or other of the two CSs can be either putting 24VDC back into a battery bank and/or generating a few kWs AC if I need to run the small welder or the angle grinder

I'd be interested on thoughts on inverters and on modern complex/sophisticated equipment like the Victron units vs something heavy and simple with a big copper transformer and a steel frame and two big handles kind-of-setup

I have a couple of quiet, (one genuine Honda, one cheap Chinese) 2.4 kW generators with 15-litre tanks that can idle inaudibly all night if need be, plus a big 5kVA genset that can run the fast-acting 3.6kW 60-litre hot-water cylinder as a convenience if the sun isn't shining, the fire hasn't been going and herself wants a shower NOW . . . so no real need for a big-current inverter.  If I had just one unit (instead of a few small ones) it'd be a 1500/2000W job, I would say

I don't reckon I give a rat's about pure sine either.  Everything I own seems to run OK on a dirty square wave with a few corners clipped off and, in my luddite-ish way I figure cos the laptop runs off of a 19.5V (DC I assume) charger thingie, it probably doesn't care if the VAC going into it is a bit dirty?  Since I am blessed to not own a TV I don't care about that either

I might put a search on TradeMe (think ebay/gumtree) for small inverters and get an idea of what sells for what $$

Enough from me - this is turning into a Glort-length rant

I'd appreciate any thoughts

Cheers, Mike

Original Lister Cs Engines / 6/1 and 3.5/1
« on: July 28, 2018, 06:41:54 AM »

Hey there experts & knowledgeable folks . . .

I have a couple of 6/1s, but also the bottom end of a 3.5/1 in the yard as well (I gave the barrel and heads to some bloke for his one)

The 3.5/1 piston is a bit lighter, I guess, so maybe the counter-weights on the wheels are different - does anyone have any experience around the interchangeability or otherwise of these, I wonder?

What started this train of thought is that the mains are probably the same bolt-hole pattern so the case could be a donor "spare", cleaner-upper for one of my 6/1s

Then I started wondering about the crank . . . am I right in thinking maybe there were two sizes journals of 3/1 big-ends and maybe (a later?) one is the same dimension as the 6/1?  Or maybe that's wishful thinking?  What excited me there is one of my 6/1s has buggered Gib keys with the heads snapped-off and is going to be challenging one day; but the 3/1 bottom end has good-looking keyways and gibs

Apart from all that, it seemed to me that if you took the 3/1 wheels off and put them on an axle in a pair of rollers and cut off the balance weights carefully until they were "neutral" balance-wise; you could just about run two flywheels on both sides of one of the 6/1s as an experiment in rotating-mass and anti-flickering and stuff like that?  (After all, the one with the buggered gib keys is never going to want to yield its flywheels so I could trim what little is left of the heads of the gibs back to nothing without being any worse off - and snug-up another pair of flywheels

Just an idle thought-train of a cold Saturday evening with the fire going and peace-and-quiet here to allow the brain to wander . . .


Lister Based Generators / micro-vee PK pulleys
« on: July 26, 2018, 10:12:42 PM »

Here you go Glort

I forget how people got onto the subject of micro-vee pulleys, but this is the driven pulley for my 3000 RPM head off the 24 wheel of the CS (should run no-load 3150 at 580 engine RPM if my count-on-the-fingers is right)

Its the aircon pulley off a big truck.  I went to the local truck wreckers with a pair of vernier callipers and checked out the pulleys on lots of engines until I found one close to perfect

There were lots of those 8PK pulleys of all sorts of diameters from 250mm downwards driving water pumps and power-steering pumps and some quite big-load sort of truck stuff

This one had a clutch in the centre as it was an aircon pulley and I cut that out and filed the stubs of the lugs out of the way

I just cut a bit of M16 plate into a circle, welded it onto the end of a bit of 40mm shaft, got the local machinist to turn it to 107mm to suit the I/D of the pulley and face-up the back of it square

Tacked the pulley in place using the thumbnail-ometer to get it flush and gave it a trial spin on the lathe to check it for true it came up primo.

$80 for the pulley and $20 for the machinist
