Then as soon as everybody who is in on this build is happy with the end results I will put out drawings for the different parts.:)[/QUOTE]

Good pickup dave.
As yourself and Herb both seem ok with this I will put out some workshop drawings soon.:)
 
How's everyone getting on? I've been making some slow progress with the flywheels.
 
Gears are done, but I've had no luck getting to the spark plugs yet
 
Hi all,
Tel, probably a good idea to wait on the plugs until ausdier gets back to us
with the new design heads etc,. May be a slight change perhaps.

Hi guys,
So sorry for taking so long.
I wish I could say I was so buzy that I couldn't get to it, buuuuuuut, truth is I simply forgot about it, sooooo sorry.
Here is what I thought of for the head.
If you want any changes let me know and I will make them so other people can build a working engine at the end.
I was thinking that maybe there might need to be a small boss on top to give the sparkplug more thread ???
I will post the rest of the parts I have changed within this week.
Cheers.

Is anyone else doing the pistons and cylinders? If not, I'll take them on. I'm asking since I may need to get yet another boring bar to do the cylinders.
 
Hi Guys
Photos Please :)

Great, thanks ausdier, now I have something to read on the plane at 5am
this morning! :)

Got 4 of the flywheels done in mild steel. I'll be shipping out once all of my parts are done. Looks like I'll be doing the pistons and cylinders unless someone else wants to make them.
 
How's everyone getting on? I haven't seen any updates for a while.
 
Hi Kaleb. All my bits are done and ready to go.
 
The flywheels are done. I've made a start on the fuel tank support columns, but will need a boring bar for the cylinders.
 
Hi guys,
I have been inundated with work since xmas so progress is a bit slow, however all
heads are machined up, just need threading.
Valves, 10 done
Guides, 4 done.

Having fitted the guides to the head (as pic), it is hit and miss that they line up
squarely with the head, of 4 giudes fitted, only one lines up nicely with the
head allowing drilling of the exhaust/inlet ports.
I have machined one giude to get correct fit, very time consuming, this thern makes
each head assy a matched set, so parts will not be interchangeable.

Perhaps shims under the guides might work?

Also had to machine the hex back from the end by 0.5mm to stop the corners of
hex from marking the head on assembly.

hopefully get some machining done today, unless shed is an oven!

Hi Guys
Im really looking forward to seeing this go together:cool:

Hi Gabby,
Piston is from Cummins Signature engine, approx 137mm dia.
They are hollow crown, (can faintly see oil hole on left side) for
better cooling. This one done 1.4 m k's at 600hp.
It is a bit techo looking I spose. Cat use the same piston too.

Hows the harbour today? full of boats I spose. I spent 20 yrs
cruising the Hauraki and further in our boat, great place!

Dave.
