That's very interesting. Shows and individuals inventiveness.
But, line boring like that is nothing new under the sun. The steam locomotive builders did something similar. They would bolt what was called a spider to the ends of the cyclinder that would hold a boring bar and they would bore out the cyclinders.
I wish I could find a photo of the procedure. I do have a write up some where of the device used. When I find it I'll post a pic.

Hi Darren
great idea the principle has been used for many years the video brought back memories of a few years ago when i worked at a steelworks in nearby scunthorpe on the maintenence side and we had a similar device. It used a similar bar on a "portable boring machine" it was powered by an elctric motor and reduction gearbox mounted on the end of the bar and was used to line bore bushes on the plant when it was too costly to dismantle machinery to do the job ( downtime is costly in a production enviorment) i usually ended up doing the job on nightshift .I have done a similar job on my own lathe recently with the job mounted and packed up on a table bolted to the cross slide the boring bar between centres driven with a lathe dog and catchplate and the feed supplied by the saddle. There are a lot of old practices out there with regards to unusual machine setups and work arounds that are slowly being lost in the mists of time as sadly machining becomes a dying art .
Cheers Paul :beer: :beer:
