I've read a few posts where it appears people have purchased shotguns and then built DR up from the action.
Can someone tell me (Briefly - i guess) what is involved in picking a suitable shotgun and building it up to a double in .416 rigby or .470.
Who is a ggod gunsmith in Australia that specialises in this work...
cheers

This website tells all the steps of making a best quality sidelock double: http://www.londongunmakers.com/
It takes about 800 hours of labor.

I think that anyone interested on hte matter of double rifle making should read Ellis W. Brown's "Building Rifles on Shotgun Actions". It has detailed explanation on the selection criteria for the actions, sleeving, regulation process and calibre selection, too. I greatly recommend that you read it. Most of your questions will be answered.

To my knowledge, the only gunsmith in Australia who has made SxS double-rifles from shotguns on anything like a regular basis is Rolph Bachnick, I think his Melbourne shingle says 'Safari Arms'. Dunno whether he will still do this though. I have one of his efforts, a .577 Light Nitro double on a Greener Empire action. I have posted the story of that gun before: newbies can read it here.
Ron Webb made a couple of U/Os on the Ruger Red Label action years ago, chambered in .375 Flanged Magnum. I'm told they were good, but I believe Ron is long retired.
Ellis Brown favours German shotguns with a cross-bolt third fastener, however my advice fwiw would be to forget the .416 Rigby and the .470 Nitro, they are fat cartridges and wouldn't leave much meat around the chamber. Back-thrust on the standing breech can be quite high with full-nitro loads in fat cartridges. Slimmer cartridges or lower pressure options should be selected IMO, despite Ellis Brown's enthusiasm!
Remember, you are dealing with shotgun actions proved for service pressures in the 3 to 5 ton range, and proposing to fit them up for 14 to 18-ton loads!!! 
While the pressure calculations are much more complicated than that, of course, I hope it still offers some sobriety to your proposal!

The "African Hunter" site has an excellent 3 part article written by a machinist who built his own 4 Bore double and then went on safari with the gun.
I think it is titled "Rebirth of the 4 Bore". Dave

"MAKEING A DOUBLE RIFLE FROM SCRATCH-WHAT'S INVOLVED???"
Not much! You simply gather some steel, and wood, and cut away everything that ISN'T a double rifle, and there you have it!
