Whats the best way to finish the worktop? I was thinking of numerous coats of danish oil, but is there a better more robust option?
You have chosen an oily wood for your worktop - a timber which can give problems in finishing. A worktop is a working item and not just for show and therefore needs to be something with a repairable finish. To my mind that makes oils of some description the only sensible finish.

.........Leave in stick for a week or so
But where? In the shed, or in the environment it will be living in subsequently? If there is any major variation in RH between the two you'll potentially have problems down the line

SWMBO is quite taken with the Iroko look so I don't have much choice, unless I use something like beech and stain it - not sure how possible that is - anyone done that?
I don't think it would turn out all that consistent - and you're not going to save a lot doing it, either. I've seen it done with oak and it didn't look right to me. I'd also be concerned with any potential problems down the line if the finish ever needed to be repaired.

I did check the cost of already made Iroko tops and apart from the time factor it works out about half the price if I make them myself. However, there is an added cost involved for me to process these as i'll need to purchase a decent dust extractor and a biscuit jointer and a bunch of clamps.
Just how do you intend to get a consistent thickness over a 9ft x 24in run, though, without access to a 24in wide thicknesser (what the factories use)? My experience (with the one and only worktop I ever tried to fabricate) is that you'll get variations in the thickness across it's length and width so you need to be prepared for quite a bit of hand planing, i.e. jack plane
then smoother not just a couple of passes with a smoother. And iroko isn't pleasant stuff to plane, IMHO. Apart from the peppery dust it can be ruddy hard work without a power planer. Have you considered that you're also going to need a 9ft long solid bench to cramp up this lot? There will be a tendency for the worktop to bow slightly along it's length if you attempt the glue-up on trestles.

If I don't finger-joint the end-to-end grain joints, how else can this be done to get a nice strong and tight join within the worktop?
Butt joint with a loose spline across the joint. After all finger joints are a modern manufacturing solution and I for one find it slightly farcical that folk want to emulate what was introduced as a continuous production technique meant to allow the use of short offcuts..... As Paul says if you end to end joint you'll need to ensure that yoeu can end to end cramp - so add some cramp heads and bars to yout list.
In any case if you look at the best quality
manufactured worktops you'll find they generally use wide staves which run the full length of the worktop without any end to end joints. I'd say the solution is to buy 10ft iroko and use 4in to 6in wide staves.....
One last point, Byron, do you have a helper (or helpers) to work with you on this and in particular to help ytou install it? A 9ft iroko worktop is a very heavy item indeed, so you won't be carrying it on your own.
