Unless you have the equipment available to dynamically balance it properly i would leave it to the experts (they aren't really that expensive)

James,
I got burnt Sunday eve tacking bits together. Face was hurting for 2 days! 
I've just ordered my prop from this guy:
http://www.autoprop.co.uk
Seemed really friendly/helpful and best quote I got. He's on holiday this week though.
These guys were recommended to me by someone at Mclaren:
www.propshaftservices.co.uk
but took me 3/4 attempts to get them to answer the phone and then they weren't too helpful/friendly. (or cheap )
HTH,
James

Volvo is your friend!
I have a volvo breaker near me and they have perfect donor propshafts for becs (off a 2 litre 740 or 840 or something i think).
Joints are rebuildable meaning you can easily replace the rear yoke with one that fits a ford diff/axle. It has a centre bearing that fits nicely
near the front of the tunnel, and a sliding joint. It's then just a case of chopping the front part of the shaft for length and fitting your
sprocket adaptor. Did this ourselves on my mates blade westy by hammering on a cds sleve. It can only go on straight - had no vibration problems at
130 mph on the track. Alternatively get the volvo prop modded by a pro, but that'll still be much cheaper than a custom shaft.

DIY Props
Unless you know what you are doing then leave it to the experts. Dunning And Fairbank in Leeds are also good.
A good source of 2 piece props is Ford as as all the service bits are cheap.
It is actually possible to do your own props, a lathe and clock makes the job very easy but careful use of a hacksaw, grinder and a pen will get the
job done.
Also if the job is done correctly then 90% of the time balance wieghts are not required, but you do not know this until it has been on a balancing
machine. However if you check the shaft for true running after welding and total run out is less than 0.1mm on the tube I would be confident not to
balance.
