Sorry to just bang photos up with no write up, but I lost the text when I was halfway thro uploading the photos, so I'm doing it in two halves now. Still can't get used to the tapping required on the ipad.
There's a couple of drawings which may be of interest.

I've spent ages just making multiples of various things, locknuts, valve guides, head gasket rings, etc.
Then I made a start on the cam drive system. This will all be mounted on the steel plate set into the front of the block.
Hopefully the drawing of the belt arrangement will show better how it works. One side is shown on full advance and the other on full retard.

I made the plate from bright mild steel, but it bent like a banana after the first cut off one face, so I've been fighting it all weekend trying to machine it to size and leave it flat. I'll use ordinary black bar next time.

Amazing stuff, Keith! Black bar = hot-rolled from the hardware store?

I'd missed this thread. Awesome project. And awesome parts.
I can't wait to see this one run.

I suspect the ref to black bar means hot rolled the stuff with the scale on it

Being hot rolled it will not warp as the internal stresses have gone with the hot rolling

But as usual I may be wrong

BTW great work on the engine way beyond me and I have been at this game a long time but never done a IC one

Wow8-)

I opened this thread on the last post above and thought you were using a cnc machine! Fabulous machining :D

Yes, black bar, as in the hot rolled stuff with the black, or dark grey, scale.
I realised the bright bar would bend, but I thought I'd be able to machine both sides and bring it back flat, but it didn't work. Won't use that stuff again in a hurry.

Bill, thank you, yes all manual. I need to get some cnc stuff one day, I've just about reached the limit of the manual machines.

Doesn't time fly?
I've got a fair few pics to upload over the next few days, to bring me up to date.

Firstly the cam belt drive gear train is in....





Then I fancied trying the cam covers. I wanted some better lugs on them this time, compared with the V8 ones, so ended up with this design,



Here is a list of co-ordinates needed to do the lugs on one side. So I had to go thro this lot 4 times, but I think it was worth it.

With the cam covers roughed out I could then line bore the camshaft bearings. I'm using the  lathe to turn and power feed, but the alignment is taken care of by running the boring bar in the end bronze bushes. Any misalignment in the drive is taken up by the  hex. allen key shaft drive..




Then I wanted to cut the combustion chambers in the heads. To get the block volume I filled the gap with plastacine modelling clay, cut it flush and then pulled the clay out. Then the clay was pushed into a tube and measured, and the volume worked out. It worked great, far better than messing about with liquids.

I ended up with a comp. ratio of 8.3:1. No pics of head yet.

Hi Keith,
Great work as usual. Where did you come by all the helical gears for the cam drive? Did you make them or were they off the shelf items?

George, I bought the gears. I didn't want to use loads of time up making them. They were from HPC in the UK. About 75 for the 5 gears.
Cheers.

Hi Keith, every time I see a post of you I have to clean my Ipad, there is drewl all over it. You are a true artist  :praise2:you brain must smoke when machining this parts, keep the mill diameter on the correct side etc. so easy to make a wrong movement and ruin the part. Keep the pics comming, although way beyond my skills I am learning and enjoying them a lot! Thanks for sharing.

Keith, I have been following your work for quite some time and I, like most, love your work and attention to detail. I know you're probably busy ornstuck on something but I was just wondering about progress. Also, have you done any thinking or research on the type of forced induction you might do?
