Saw this for sale on ebay they said it is a rifling tool but it looks like a old push screwdriver
to me do you guys think someone could make a rifling tool from one of the old screwdrivers?


This was the description.
barrel rifling tool manton london made
barrel pistol musket rifling tool two twists in seven inches cuts rifling grooves inside barrels very old brass steel and walnut.







 
I dont have much of an answer to the question, but 2:7 twist is 1:3.5 ... seems a lot fast for anything.

Looks like blastattack beat me to it!
 
Ha. Neat. I was going to make something similar this winter for my potato gun. I figured I'd use a piece of wraught iron railing to get a half decent twist rate, then pull a plug through with 36 grit sand paper a bunch of times. I'll probably have to breech load it afterwards. Dunno if it'll stabilize the tater, but figured it'd be fun to try.

Oh, and if that contraption IS a rifling tool, it's from an era before they knew how rifling worked.
 
Presumably you held the floating collar tight against the muzzle and pushed the handle in and out a few dozen times .. then re-indexed the collar.... thats just about the right state of technical advancement I would have expected of the British firearms industry .....probably used until they banned pistols.
 
Its a drill.
agreed .. looks like someone has ground off the thread that held the collet nut .... and slipped something thin into the collet . BUT ... being reasonably familiar with the low state of British technical achievement (I owned a 1950 Anglia and a 1961 Sunbeam Alpine) I imagine at least one of the old "London Gun Houses" has a similar tool sitting in drawer somewhere!
 
We used to call them yankee drills.
Not that pos you didn't.... a "Yankee" drill or screwdriver is a lot more sophisticated than that piece of Limey crxp....... sorry but even the Indians have proven they can build a better mechanical device than the Brits... look at the new Jag...
