Hi Alex

I don't know where you live, but these guys, on the south coast, were very good 10 / 12 years back when I was working for a towing and dredging outfit in Poole.

Hi Spif

Given that the roller is not a 'high speed' part knocking one up yourself shouldn't be too hard.

Welding a couple of bits of steel out of the come in handy box to the head of a bolt of the relevant size / thread and then fettling it up with the 4 1/2" angle grinder will get you going. it's hard to say from the Photo but you could probably re use the roller and pin.

Just get the correct bolt!

Thanks for that, I've ordered one, Looks like an easy way out, with a nice display, once I've worked my way through the Chinese instructions!

I found and ordered this too

Much simpler, just twiddle the pot.

Maybe later I'll go for a double delay and have a pre heater kick in first. I'd rather keep it simple to start with tho....

VP,

Start searching the local barns for a Casal or Famel moped

Do a full restoration, fill the tank and set off for my place, you should get here in time for my 70th birthday!

Hi Glort

Maybe you've got on to something big with  backyard solar

If you set up a small to medium sized solar farm in your back yard or up your Dads place, with 'repurposed ' equipment and get it checked and certificated by a qualified inspector you could apply to the local power company to be a registered suplier.

When they start to bleat about the age of your equipment you point out that it is completely safe and the proposed connection exceeds current safety regs by far.

It's slightly less efficient than current equipment, but continues to make an environmental contribution, rather than being a disposal issue.

You then play your hole card.

I know you despise the 'greenwashed' but they will be failing over themselves to support a bloke that is using perfectly serviceable kit to save the planet rather than burying in landfill to poison it.

A month or so jumping through bureaucratic hoops and being in the local media whilst pretending to be greenwashed yourself and you'll be making money for the rest of your life.

Just don't forget it was my idea and 10% of the profit isn't very much....

Cheers
Stef

Hi VP

That's quite few questions!

To start at the top....

Yes, a lot of the fun is in rebuilding and then running an engine, however, last year I bought an off grid barn. A lot of CS Listers, as Startomatics, ran isolated farms etc, for years,

That's what I want mine to do.

Sure, I could have a silenced, modern genny, but it won't be as easy to maintain as a CS. With a few hundred pounds worth of spares, head, barrel, piston, rings .com rod, crank and bearings, along with a modest box of tools I can have an engine rebuilt by supper time.

The CS will run happily on the WVO I have a good supply of, and lots of other waste oils that may come my way in the future,

It will still be a museum peice, the brackets that hold the modern stuff to the engine are all mounted on existing bolts / studs and it will hand crank the same as ever.

I'm guessing as a policeman you live an active life, me too, I'm 6 feet tall, 14 years in the Royal Marines, and married to a small lady who worked on a bank. She knows case more about pressing buttons than I ever will, but anything bigger than a lawn mower, with a hand start is going to be a bit beyond her.

Years back, whilst working with the Parachute Regiment, I was asked why I was wearing a pullover a week before the Regiment had changed from summer (shirt sleeve order) to winter rig (pullovers) I replied that the Corps had issued me the pullover and left it to me to decide if I was cold.

That's how it is with the CS, at 65 Years old, with the start of arthritis, and the winters just as cold as ever, 1100 meters up in the Pyrenees, I'm fitting, now, the electric starting kit before I get to the stage where I can't get out of bed and have to get the Wife to go and press the button on the wall because I can't remember where I left the remote fob!

We've got plenty of wine, Carolyn makes her own bread and I can see the local cheese makers house from the barn, in a couple of years time,when you've polished all the museum exhibits, and I've got the roof on the barn, pop round for lunch, we can take turns starting the CS, just to work up an appetite!

Cheers
Stef

Hi All

So, after successfully mounting a starter motor to the CS I began thinking about a starter system. Wanting to use the fuel shut off cam to close the rack I went down the car door locking solenoid track.

The cheapest way to buy them was as an aftermarket kit, £28 from China via eBay, delivered to France.

https://www.ebay.co.uk/itm/193124312207

The kit contained 4 solenoids, bracketry, two remotes and the control unit.

Having opened the box I swiftly came to the conclusion that I may well be able to use the whole kit, remotes and all. It has connections for locking the door (s) from the inside of the vehicle that would serve well for ‘local’ control.

I fitted a solenoid to the fuel shut off lever but as it was less than positive I added an extra spring behind and inline with the lever to render it ‘bi-stable’ - ie, it flips through the central position and rests at either end of it’s travel under tension. With a bit of adjustment that worked really well.

To change the direction of pull, the unit reverses the polarity of the short ‘pulse’ to the solenoid, when changing from ‘lock’ to ‘unlock’ (now start and stop) Using a diode on a second solenoid feed meant that there was only a pulse on the unlock (start) pulse.

I tried to use this pulse to engage the starter motor

I played about with a 12v H3y - 2, 0 to 10 seconds delay timer and a standard auto relay, but as I understand it, this, and every other timer I can find, delays the power rather than supply it for the specified time.

So, please can anyone point me towards a timer that, on receiving a short 12v pulse, latches on and supplies 12v for between 0 and 10 seconds, (adjustable, to allow for summer and winter starting) and then unlatches / resets until the next pulse.

I realise this is an ideal Arduino or Raspberry Pie situation, but as I’ve mentioned in previous posts, I do to electronics what grit does to clockwork, (Terry Prachett) So I’m looking for something off the shelf, with two wires (+ & - !) for supply, and a switched contact capable of operating  the starter solenoid. If this means feeding via a relay that's fine.

As usual, all comments, help and criticism, positive or not, are welcome!!

Cheers
Stef

Thanks for that, Listeroil.

Exactly the answer I was hoping for!

Looks like I'd over estimated the CS compression by around 20%, I guess that makes it a bit easier on the Landy starter, dropping the ratio to 17.5 to 1 would help a little more, again as Glort has said, if it cranks over for a few turns before it runs up it's not going to hurt and slinging the oil about before ignition can only help.

Next step then, is to pull the top end and and add a spacer under the cylinder, hand crafted from the traditional breakfast cereal packet.

Here, in France, Lidl's cheapest beer comes in a 24 bottle 'slab' and serves just as well, it feels a little bit more 'compression resistant' than cereal packets. We seem to have more of it available, for some reason......   

As a further aside, the over spray between the teeth on the flywheel
Gives a good indication of how well the starter motor teeth are meshing when it comes to setting the alignment up.

Hi All

A couple or three nights back Glort posted something to the effect that the stupid mistakes that one makes are the hardest to detect but, once found are the easiest to rectify..........

Whilst gazing at the alternator drive shaft yesterday it occurred to me that it looked shinier  than I remembered, yep, it wasn't the belt slipping, it was the pulley spinning on the shaft.

Guess who, having put it all together to see how it looked, forgot to tighten the pulley taper lock? The schoolboy error was compounded by me not fitting a key - both flywheel, pulley and shaft have key ways.

As the pulley is a smaller diameter than the flywheel and on the 'inside', it wasn't easy to see what was going on, well that's my excuse!

The flywheel pulley key way is a little smaller than the 3/8" one common to the shaft and pulley so I knocked up a hermaphrodite key from a scrap of 10mm steel AND added witness marks to the flywheel and pulley. If it moves again I'll know.

The upshot of all this is that the starter will now turn the Lister over with no trouble, even from a standing start, with the crank at BDC, just before the compression stroke, and with the compression on high.

It starts easier on high (as was the original intention) but 7/8 'firing strokes' and it fired up the lower compression.

Again it was around 15 degrees in the barn, but I feel colder weather will be far less of a problem.
 
I believe from what I've read (on here!) that the Startomatics had a blanking plug in place of the change over valve and thicker gaskets (or maybe a spacer) under the cylinder to achieve a compression ratio somewhere between high and low, If anyone can point me in the right direction I'd be grateful.

In conclusion I'd say that the experiment is a roaring success. with the exception of the water jetted boss (I didn't have a lathe at that point) everything was done with hand tools and MMA - stick - welding, £50 / £75 down the scrap yard, maybe even less, depending on what you go for, and there you go.

If you can find something with a larger diameter flywheel and get the starter between the Lister and the alternator it's going to look neater and more compact.

Bleeding is going to be a lot easier too.

Add a 12v car alternator or a 220v ac / 12 dc charger to top the battery up and reliable push button start is yours.

It's definitely spurred me on in the direction of solenoid operated shut down system and a remote watch keeping panel, I suppose that's well on the way to re inventing the 'Startomatic', all suggestions gratefully received...

Cheers
Stef

Hey Bob!

Welcome back, nice to see that you're moving ahead.

Ref the heat exchanger, didn't Ed Dee post up quite a bit on the subject a while back?

All the best

Hi Mike

I'm not sure what the advantage of driving the motor via the gen head is either.

When I started collecting bits my plan was to mount the starter between the alternator and the Lister, but as I said above, it won't work without a larger diameter flywheel.

Quick, adopt plan B.........

That was the entire rethink process!

I looked up the compression ratio for a 2 1/4 Landy engine and it seems to be 23 /1, much the same as a Lister on high compression, so I'd guess (happy to be corrected here) that the force to pass TDC is the same, more or less, regardless of the volume. (unless the bore / stroke ratio comes into it, somehow) however there must be a far greater amount of inertia to overcome, given the weight of the Lister crank, flywheels, conrod and piston, not to mention the Stamford alternator, pulley and Landy flywheel.

It does take a few seconds to get up to full chat, 190 rpm, but at that speed it will keep cranking over compression with the fuel rack closed.

The gearing is approx 2 1/3 to one, I can only guess that driving the Lister direct would result in a lower cranking speed, but more torque to pass tdc on the compression stroke.

I suppose a neat arrangement could be had by having the vehicle flywheel on a jack shaft, with the driven pulley in between the Lister flywheel and the crankshaft, keeping the cranking speed inline with the starters original application. The starter motor could then be tucked away on the centre line of the bed plate. 

I've only got a narrow serpentine belt, it's about 2/3 the width of the Landy 200 tdi belt, maybe that's the next plan?

Cheers

Thanks for that, Veggie, he's amazing!

That led me onto this...

https://www.youtube.com/watch?v=Y-szy7TrlpQ

Which must be the first of the series.

I wish I could speak Russian, I've picked up a few words over the years, working with east block engineers and in Kazakhstan, where Russian was easier to use that Kazakh.

If we could clone his DNA with that of Bert Munroe and Butch - 38ac and gave the baby a Whitworth spanner to cut their teeth on it would be welding before it could spell Lego.

If it was a boy, even better!

Seriously, he's discussing crank balancing and building, bearing alignment and then doing it, after knocking up 'knife and fork conrods.

Ok, it's not going to be a highly stressed unit for cracking out sub 10 seconds over a quarter mile, but the use of a basic workshop and tools is a joy to watch.

He even welds whilst wearing flip flops, for crying out loud, what are heroes made of?

Hi All

At long last and thanks to the lockdown I've finally assembled the parts for the electric starter.

It's quite a simple affair, I got a friend in the UK to get me a 12mm steel blank knocked up - water jet, to fit the centre of a Land Rover 2 1/4 flywheel (left over from when I changed the engine in my Series III for a 200 tdi from a Discovery) onto a weldable taper lock bush sized to fit the shaft on the Stamford alternator, alongside the serpentine belt pulley (there's just enough free length), that took a couple of years or so.

So, in the middle of last week I dragged the Lister from under the covers in the corner of the shed and set too.

First problem was rotation, it's not possible to fit the starter between the engine and the alternator, the body of the starter motor fouls the body of the 220v alternator, so it had to hang off the rear, on the other side. A shame really, it would have been a neater installation. This meant turning the alternator round and running off the other flywheel. The other option was start again with a larger diameter flywheel, but that could take another couple of years....

Obviously the alternator, apart from the direction of the air cooling) is indifferent to direction of rotation.  As the alternator mountings are not symmetrical it was out with the disc grinder and start again.

Once it was re aligned I shaped a short length of 3" of angle iron to take the starter and aligned it to the flywheel with a square and tacked it to the chassis. I set it up to be adjustable in the manner of a vehicle alternator, to allow for the Stamford alternator moving slightly as the drive belt is tensioned.

First results, with a set of jump leads were a bit disappointing, it wouldn't get over compression, even winding the engine as far back as possible to give it a run up, but with 8 /10 rotations there was enough momentum fire up a cold engine when the decompressor was released - at 15 degrees ambient, I doubted if it would at zero!

Anyway I carried on and made a decent job of bracing the fitting up, well, as decent as my welding allows! and once I'd connected the battery with a couple of short leads and decent terminals the results were much improved.

There was so much more torque that the serpentine pulley was spinning inside the belt until the engine speed picked up and then it was far faster, I turned the rev counter on (it's supplied by a PP3 battery) and it was clocking 190 rpm after a few seconds. the best I could manage with the handle was 165!

With the slipping belt problem out of the way it might well get over the compression stroke from a standing start, on 'low' anyway.

I've sent off via eBay for some belt dressing as I feel the belt is tight enough already - it doesn't slip under a 3 kva load - should that not provide a cure I'll get a longer belt and knock up an adjustable idler pulley to get more 'wrap' around the driven pulley.

I suppose the next task is to set up a control panel for 'stop and start' with solenoids to get just a little bit closer to a Startomatic.

There's probably enough time left in the lockdown........

Cheers
Stef

That's certainly taken a beating!

For what my six eggs is worth, assuming you don't want the machine to run at the max 24/7....

I'd get an infra red thermometer and warm the rod with a propane torch up to somewhere around 650 degrees c and hold it there for half an hour or so then wrap it in an old fire blanket and let it cool slowly.

Make up a couple of dummy shafts, for the big and small ends and then take it down to the local fabrication shop on a Saturday morning and slip the boss a tenner to push it about in a brake press until the dummy shafts are as close to parallel in all aspects as you can get.

Clean it up, give it a good thick coat of inspection and if you have access to the kit, crack test it. The guy in the fab shop will probably let you have a couple of squirts, to save buying the whole kit.

https://www.ebay.co.uk/itm/Flawtek-Weld-Metal-Crack-Flaw-Detection-Complete-3-Part-Kit/141181661281?hash=item20df153061:g:KIQAAOSwHfxdlzbk

As an side, you don't half get a lot of interesting stuff when you check eBay for 'Crack testing kit'!!

Based on a good outcome I'd be tempted to run the machine at half then two thirds power and if the rod doesn't let go then I'd live with half power from then on.

That would give you a cheaper start up and if you are happy with the machine and want more from it you can swap the rod out at your leisure.

Cheers
Stef
