Kelvin F4 rebuild

[tom_c]

I spoke to willie earlier in the year, but he only really has poppet valve spares not ricardo ( e,f and g) I was trying to source a block for a 6 HP paraffin engine then.

Stone the crows. I don't mind a challenge but that block......

[tom_c]

More paint, and a glow plug to vaporise paraffin when the vaporisers are cold

 

Just need to fit it to an engine to try it now, hopefully the F2 will be back together in the next couple of weeks.

Some photos of the second cylinder block, thanks to Billh for donating this block

Hopefully more to follow if I get any time to work on it!

Finally had some time to start looking at the crankcase and start to remove the flywheel.

hoping to start on the gearbox soon,also sorted some new bits still in their packaging

My word...... excellent work. Great skills.

Flywheel removal- unscrew the flywheel nut until it's flush with the end of the crank and hit it end on with a sledge hammer, one blow should do it. 

For those unfamiliar with  Kelvin Fs, the flywheel is on a taper with woodruff key, different from  the bolted on Js and Ks. Good work Tom and I'm envious of the new gearbox parts.

We tried a big hammer......several times.....

[tom_c]

I have a bigger hammer! 

[tom_c]

The flywheel is off, a bigger hammer sorted it!

hopefully more to follow later today

Starting to go back together now, hoping to get it in the boat later this summer

[tom_c]

Here are a few more photos of recent progress, more paint and the crank is back in and a new oil drip bar fitted as the old one was damaged. I hope to have cylinders fitted soon 

And a photo of a rebuilt E2 with the F4 in the background

hopefully more to follow soon.

To position the engine in the correct position on the existing engine beds, I have had new engine mountings cut  ready to be bolted to the crankcase 

hopefully more to follow on return from Panto land

Curvy!

As well as the usual jealousy I now have workshop/shed envy

[tom_c]

Now that the panto season is over, I've had chance to continue with the rebuild, this engine is slightly different to the other F4s out there in that it has the optional governor fitted to it.

The propeller and shaft are now fitted too, hopefully it won't be too long before the engine is in now

Looking good. Hope to see it running in may?

[tom_c]

Hope to have it running before then, how about a tug of war in may?

[reveriecanaltradingco]

Looking forward to seeing it.

Our boat does go backwards well haha

Looks brilliant, I thought I was the "patron saint of lost causes" in the words of my pal!

One question: where on the canal network do you think you will be able to buy paraffin in "engine size quantities", not just in 5 litre containers? The canals are very much set up for diesel boats!

We had a similar consideration with a coal fired steam boat - 20kg sacks don't go far and are an expensive way of buying coal in large quantities!

[tom_c]

I'm planning on fitting a very large tank, and having a tanker delivery every year, kerosene is a good fuel or the mix of diesel and petrol from people misfueling their cars! 

Tom

[D. W. Walker]

Sounds like a good plan, and if you have a route to the "misfuel" stuff that would be great - and probably cheap!

I have a "recipie" to make up fake Tractor Vapourising Oil if you want it, petrol/paraffin tractors seem to prefer it to straight paraffin, as they don't usually work hard enough nowadays to get hot enough to run well on paraffin

[Ray T]

Brilliant work. After looking at all this "engine porn" I'm off for a cold shower.

Is that a metal clad glove you  just chucked on the floor in front of  Kerosene Castle? Might still have 3 or 4  working pots by then. I found another  'E' bit for you in the latest tidy up.
