Next was to drill the cam tunnel out, one drill size under so it could be reamed out

Then drill the crank shaft tunnel out, one drill size under and then ream the hole to size

Looking very cool. Are the new castings machining as nice as they look?

 

[michael-au]

Hi Cogsy
Yes the new castings are good and easy to machine, no holes
Very happy with them

Nice work, still havent had any time on mine, got the ignition bench tested the other day distributer spun by hand and fires all four plugs, earning a living keeps interfering with progress.
Great work as always you are getting close now to.

Started to get the block setup so cylinders can be bored
The block is mounted on a rod going through the crank shaft tunnel

The dividing head will be set on zero, so it can then be rotated 45 in both directions so the top of the cylinders will be at the same angle from the Center line

View attachment ImageUploadedByModel Engines1471867005.996027.jpg

A dial gauge was used to make sure the rod is parallel in both directions ( from the top and from the side of the bar)
The bar is 1/2inch silver steel with a Center hole drilled in each end

 

[michael-au]

The way the block is setup now will be how it will stay until the cylinder bores and head bolt holes are drilled
Also the top of the block will be machined to the correct dimensions ( from the center of the crank shaft to the top of the cylinders) a small amount will left to machine off after the cylinder liners have been installed, so that the block will be flat all the way across

I made an expanding mandrel to holed the block in the lathe to turn the water cooling passage around the cylinders

Managed to get a little bit more done this week
Made the cylinder just need to put them in the block
I will put the block in the oven for a couple of hours and the cylinders in the freezer then hopefully they will slip in to place

Finally got the cylinders install and machined off level with the block

View attachment ImageUploadedByModel Engines1497252314.963689.jpg

View attachment ImageUploadedByModel Engines1497252330.617021.jpg

Put the block in the oven for an hour at 250 deg and the cylinders in the freezer
Installed one cylinder at a time put the block back in the oven for around 10 to 15 minutes between cylinders
The cylinders fell in the block with out any pressure and when the block could they were tight
Now I need to hone the cylinders and then make the pistons and rods

 

[Cogsy]

Looking sweet! It'll be running in no time...

Piston blanks ready to machine out the inside of them
