Beautiful work which I could not come near to, but should the lower pipe under the sump not be routed under the mid position pipe closer to the sump which would look much better?

Hi it is routed as the plans described , I presume this is how they route on a full size engine.

Also i think the angle of the picture makes it look a little more untidy.

Hi David

I am not certain but guessing that on the full size any such pipes would be clipped at one or more points to avoid damage by vibration, same with fuel lines and electrical cables, not good to have any of those damaged.

Nice work on the engine.

Brilliant work Love it.

I milled the cooling fins on the sump underside

then drilled through for the sump plate

The sump plate and oil union made from stainless

These are the parts to be fitted to the sump

The oil feed from the pump runs through the sump before running up to the main bearing

Lovely!

While i was soldering the oil lines i cut some brass tube and made the oil filler and

breather pipe.

Casting for the carburettor was a little rough looking

Tried to tidy it up as much i could while opening up the float chamber and bore

The float chamber is a dummy so the fuel runs directly to the jet and metered by a needle.

I made these from stainless and also a brass float chamber lid and butterfly.

Carb and manifold

Spark plugs , i can buy 1/4 32 plugs but they are quite expensive so i had a go at making my own.

Started with some steel hex bar , Corian offcut for the insulator and some 1mm tungsten rod for the electrode.

I first turned the body leaving a little extra for the electrode, i would have threaded them but i realised i did not have a 1/4 32 die so i ordered one

I milled around the electrode and then undercut with a small diamond disc

I then used a flat bottom cutter to drill through to the undercut and form the electrode. The body was then counterbored using a drill and leaving a taper for the insulator to seal against

The Corian being turned to fit the body and drilled through 1mm for the electrode

The insulator is loctite'd in , i also left a slight 'lip' on the top of the body and this was pressed over slightly holding in the insulator. I soldered some brass thread to the tungsten ready for being loctite'd in place

Finished plug

While i was in the grove i made a couple of even smaller plugs into earings for the Gf.

Never made spark plugs, but doesn’t Corian start melting over 100c?

Her name wouldn't be Rosemary by any chance ?

Nicely done on the plugs, by the way.

A few pictures of building the engine up

Camshaft

Crankshaft

Rods

Barrels

Heads

End case / oil pump

Timing camshaft

Time to make a stand , i was given a chunk of alloy a while back , apparently it was used for securing power lines and i have been wandering what i could use it for.

So i cut it in half with a slitting saw

Then milled away to form the stand sides

A couple of cross braces and engine mounts and i now have a stand . A bit unconventional but i like it.
