Bob,

So, have you decided to grind your own needle, or get yourself to a sewing shop and find a darning needle?

I love the brass carby!!

Thanks Guys for all your kind words and continued support. :bow: :bow:

I am very happy with the new camera and I am thrilled that you guys like it too ;D ;D

Jack - Of course I don't mind, I am more than a little flattered.

George, at this stage I will take the darning needle option. :

Best Regards
Bob

Hi Guys,

Today saw the main body of the carburretor completed and boy did I have some fun cutting the external threads

The first outside thread.

Tapping the internal thread for the feed pipe and needle valve.

Operating the lathe by hand to give a good start to the external thread.

The finished body

Knurling the lock nut for the engine/carby interface.

The body fitted to the engine.

And that was it for today.

That's not just engineering, it's art! I continue to be impressed with every post, can't wait to see it run.

On another note, thanks very much for the PM re the rotary table chuck mount, I bit the bullet today and picked up the 8" version of the Vertex table and I picked up an old cast iron chuck backing plate on the weekend for $5 which I'll modify along the lines of your plate so I can mount both my 3-jaw and 4-jaw chucks.

Move that file a bit to the left, it looks like a propeller!

The engine looks great, the carb is excellent, worth the effort making it from solid. So when will it be running? You should stream the start up live!

Great looking carby. I was just thinking of all the ways I could have buggered up such a (for me) complicated part. Congratulations on a great job :bow:

Cheers,
Phil

"That's not just engineering, it's art!" - Gavin have a look at some of the work by guys like Cedge, Paulo, Metal Mickey etc and there you can see art. Glad you went for the 8" rather than the 6" RT. Good luck with the backing plate.

"The engine looks great, the carb is excellent, worth the effort making it from solid." - Nick thanks, I was very lucky it did not turn into a propeller.

"I was just thinking of all the ways I could have buggered up such a (for me) complicated part." - Phil, I very nearly did bugger it up hence the 2 different thread diameters on the X piece. Could not get the tap to start and chewed off a good 1/8" of the original. That's when I hit on the idea of a hand cut before trying the tap. Just saved my bacon. ??? ??? ;D

Bob as you well know :bow: ........... that's the difference between a "Fitter" and an "Engineer" .......... as an Engineer you find a way to make it work .... even if it means making it again, ..........and again ........err ........... etc 8)

Nice work ........as ever .... 8) , now ........... who was it that suggested streaming the video of it's first trial run, :

CC

 

[Maryak]

Thanks CC,

Your comments as always helpful, complimentary and amusing.

At its' 1st run I am sure there will be considerable streaming, but I doubt you'd want a video of this particular stream.

Best Regards

Hi Guys,

Despite our site problems, which I know our admins are working night and day to try and fix it,

the show must go on.

Disaster with the fuel pipe, ah well, "Life was not meant to be easy," (quote by one of our more observant Prime Ministers).

Brass for the fuel pipe and valve seat

Threading the fuel pipe.

Test fit to carby body

Drilling the valve seat.

The valve seat

A poor mans collet for the fuel pipe

Disaster the fuel pipe snapped - What did I learn ??? ??? The fuel pipe 1/16" hole must not extend up into the threaded section of the pipe.
I made the collet too long straining the pipe when I removed it

Gave up at this point and took me and my micrometer to the ladies sewing shop. Received some very odd looks when I miked the darning needles.

Ah well tomorrow is another day and another fuel pipe. : :

I can just see some old ladies now in a corner of the store... "Hey, what's that perv doing with the needles over there?"

I am sure they had a head scratcher on that one for sure!!

Sorry to hear of your set back! I am quite certain that you get 'er done!! It looks great!!! :bow:

 

[Maryak]

W/E,

Thanks for your continued support and input, Friday was a dead duck, paperwork and more paperwork.

I should be grateful that it does not happen very often.

When that was done an afternoon nap

seemed far more attractive than a fuel pipe.

Things will slow now as we are busy making all our selections for our new home, (taps, baths, tiles etc.etc.) and we need to be sorted by 15 Dec.

Best Regards
Bob

Hi Guys,

Today saw fuel pipe No2. actually finished without any drama.

Here's a bit of a run down.

Attempt 2 - Note the big lump at the end for the centre.

A shorter poor mans collet.

The completed fuel pipe in the carby - (and that's where its staying)

Knurling the Gland knut.

Threading the gland nut.

A view down the carby to check alignment.

The gland nut in place.

The darning needle at the darn right length to become a needle valve, (I hope).

Hope you had a great weekend.

We spent the rest of the day selecting bricks and tomorrow is tile day wall and floors in the wet areas.

 

[wareagle]

Bob,

I am glad to see you have the fuel pipe sorted! It is looking like this will be a runner here pretty soon!!

Best wishes,
W/E

 

[Philjoe5]

Bob,
Nice work on that carby. Thanks for the update,

Cheers,
Phil

 

[Maryak]

W/E and Phil,

Thanks as ever guys for your continued support and encouragement

We (I) have had an exhausting day selecting all the wall and floor tiles for the kitchen, bathrooms, Toilets and Laundry. Early on there were a couple of tense moments. But I must say Galina's sense of style, colour and proportion is much better than mine and she only strayed from the spec by $200. A damn fine effort by Mrs M. :bow: :bow:

Tomorrow should see me relaxing making a needle valve

Best Regards
Bob

 

[Maryak]

Well, blow me down the needle valve is finished and I made a start on the fuel tank

Knurling the needle valve handwheel.

Threading the needle :

Test fit of the needle in the body.

The needle in the stem before soldering in place.

The gland is packed and the needle valve is in the carby.

A view down the inlet to show the needle valve on its seat.

The carby and engine.

Aluminium for the fuel tank top.

Counter boring the tank top before threading.

And that was that - Tomorrow is hummer the plumber for all our taps, baths, basins, sinks etc. - Wish me luck

 

[Philjoe5]

Looking smart Bob. A real engine is taking shape

Cheers,
Phil

 

[Maryak]

Phil,

Thanks again. :bow:

Best Regards
Bob

 

[CrewCab]

Knurling the Gland knut.

Bob .............. are you sure that's legal allowed :

Joking aside though you are really on a roll now .......... absolutely brilliant thread and it's just going to get better I feel .......... thanks for taking the time to document your exploits 8)

Happy plumbing thingie's ;D
