In fact I'll be doing again in the future but for a different Enfield...... and a different thread.

Barrel vice and action wrench are easy to produce but as your starting with just the body then the hard work is done, if you go the Savage lock nut route then you can get away with heavy duty stuff, all depends on your metal work skills, best vice I made was lots of plates that were bored out to a Enfield No4 barrel shape at the Knox form, (think of slip friction) but even with that I needed a long cheater bar to remove No4 barrels......

There was a link somewhere to Surplus rifle, there was a very good article on a No4 converted to .223 someone may be able to find it.
Your locknut idea is interesting. Would it be safe to make it a takedown rifle with that method? The thing is I'm trying to keep the external appearance as close as possible to the original jungle carbine, hand guard and all. I have a scanned copy of the .223 jungle carbine article from shotgun news which seems to have some info on the rebarreling procedure.
