Trying to get my head round it

So I have managed to grab a few hours whilst waiting for tools to arrive and done the not very fun task of cleaning the engine up so it can be painted.

Also managed to grab a nice unit that helps with a cradle start up of the engine. But today the clutch came off. I managed to borrow an air impact driver and the propper tool that bolts on through the starter hole and locks the fly wheel, so not much effort needed. Then the locating washer fell out in 2 halves (it is not supposed to be in 2) and then the clutch came off to reveal a fairly scored shaft. That shaft would be the end of the crank shaft so tat would be a knackered boss in the clutch and a knackered crank. The boss is only a few pounds and easy to swop ...the crank is a ball ache of a game changer to the engine project. This is make or brake for this engine financially, so the father in law is lined up to come round and guide/help me tomorrow to strip a load of stuff off and hopefully split the block and gear box. At that point I am hopeing that the gear box can be checked over and the piston rings can be checked. It really isn't going to take many more broken parts to justify trying to get another engine :( or just bollocks !!!

The road is never an easy straight forward one when your restoring a car, and the part engine strip was more of a side step leading to a better quality engine. This turn of events though is more of a kick in the knackers, I have just gained a truck load more hours on the job and the parts bill is almost certainly going to destroy all of the money from the reserves for this project. A brand new crank is £250 alone plus gaskets and bearings, I have already found a second hand one that has already been reground so it is good to go saving almost £100 but if that route is taken a full new clutch should be put in and a new oil pump has been suggested as well if I have it split down that much.
The other slight problem is I am in unknown territory from this point on, there will be a lot of reading going on and also finding out what specialist tools I need to get hold of as I already know that some of the parts need to be set up amazingly accurate. Like micrometer accurate, crazy clean and balanced. None of those 3 things I an very good at and balancing the clutch I am not even sure where to start sorting that out apart from moaning about a shite design creating an unnecessary complicated process. Even the workshop manual states it was an oversight.
But the engine looks shiny and the head is now painted ..... woo hooo ! Not as excited about that as I was this morning.
