They made barrels for a long time before the "gundrill" was invented.
Look up D bit Drills. Or Half Round drills.

But gun drills are pretty cheap, and suitable pressure pumps are in almost every car or truck (power steering pumps) if you don't mind running slower than the guy that has the proper gun drilling machine.
All good info. Thanks. Really the project is about doing it on the cheap to get SOME kind of success then to add $$ to improve quality and turnover (as in speeding things up) btw home job not for customer.
But maybe make the jig to push oil down a used gundrill maybe the way to go on this one. Leads me to the question of running these things at lower speeds ei 1600 rpm. Will this still work?
Thnks in advance
Yes.
Being careful. Accepting that you will lose the odd one, esp. at first. Spending a LOT of time backing out the drill to clear chips.
I have read that Harry Pope used twist drills on an extension to drill many of his barrels. Much care and attention in setup.Much of his gear was said to be crude and simple. But he learned to use it to his best advantage.

I see from your location why you are asking.....a $100 barrel in the US magically becomes a $400 barrel out here.......and thats if anyone can be bothered to import it,with all the paperwork....lots do use powersteer pumps,but many pumps have complex valving in the pump body to reduce power drain at no demand........but steer pumps are also tolerant of slight swarf,roller type anyway,which hydraulic gear pumps arent.Pressure cleaning pumps are also pretty cheap,and should handle soluble oil solution ,or a non oil water base no problem,and pressure rating is ok........the flow is mainly to wash out cuttings.....oily compressed air has also been used at times.......anyone quotes the Pope claim has never tried,its a major PITA......fancy taking a week to drill a barrel........incidentally,Howe claimed the cutting should come out as a single ribbon,puled out by hand.....if the ribbon broke,start again.
Thanks. Vid explains alot.
I didnt see much cutting oil coming out, are you running some sort of mist coolant/oil ect? Or am i plain blind.
