Wow, takes me back 50 years! We had a slightly more production based set up but single ovens, we were doing up to 30" diameter tubes.
Our glass worker was a lot better at re-necking, you could not see the join, and we pinched off by hand which was a bit scary. No roughing or diffusion pumps, too dirty, we had cryogenic and getter ion pumps.
We had a screening room which was kept clean, some of the phosphors are dangerous to heath, and we produced our own gun assemblies in a very clean room and never handled them.

Me to, we had a firm quite locally that we got our tubes from and I used to stand there watching the process - no health and safety then of course.

That's quite something.. I assume you bought in elements to build them with- coated cathodes, getters, etc? CRT building seems such a black art, and yet not that long go, companies capable of re-gunning and re-phosphoring seem to have existed in every major town.

Yes there were Re-gun companies just about everywhere. & as previously stated Health & Safety was not priority.
There was one company that I remember well, In Mildmay Road East London, where there was a young lad tasked with cutting the necks off the duff crt's. This he did using a piece of nichrome wire fed from a 12v car battery. Most of the time he got it right, but when he didn't there was a very large guy next to him who would give him a clip round the ear if he damaged a tube!
Some of the ovens had holes in the side where the odd crt had decided to give up & implode. All good fun. I've just remembered another little known fact; some of the girls that used to fire the getters developed odd marks on their thighs.
This was traced to those who were wearing suspender belts with metal clips, that formed a 'shorted turn'. The heavy cable with the loop on the end, that was placed in close proximity with the getter, would occasionally be pulled across the girl's lap. There was sufficient stray coupling to give them a nasty burn. Those with plastic clips of course didn't have a problem!

Anyone else having trouble?

SBW Tubes Silsden West Yorkshire comes to mind they used to call at our shop every Friday!

My early days in the Trade i would call at Kirkwood road Cambridge to collect a van load of re gunned tubes from Solus. Then spend the afternoon fitting them to our rentals.

As a child I recall going to a Merseyside industrial estate to pick up a tube for our TV (either a Pye twenty-six /CT204 or GRUNDIG 6010 ) and there was a huge skip nearby piled to the brim with old tubes. Presumably they were the ones that weren't worth regunning?!
