Devongunsmith Diaries #16 Purdey barrels for reaming chokes to standard steel

[@SimiPair]

I have seen gunsmiths in the US use reamers with pilot tails to keep the reamer parallel to the bore.

[@devongunsmith4698]

Yes of course.. they should be breech fed to stabilise correctly.. The channel premise is to work with tools easily available.. not special tools.. With sufficient skill the backwoods gunsmith can operate adjustable reamers easily..

Fascinating look at the Gunsmiths work, thank you.

[@devongunsmith4698]

Please let me know what content you’d like to see, and if the jobs come in, I’ll feature them 👍

[@dc6869]

Your videos are getting better with every one you do.thanks for doing them 👍👍👍

[@mikeproctor3664]

Would like to see a video on installing a leather pad

[@stephenhastie3801]

Another great vid 👍

Glad you enjoyed it

Thank you for a your interresting videos. Is reaming longer forcing cones the same process? I had that done in a old shotgun of mine and i am happy with the results. Less felt recoil and patterns good with most steel cartridges.

[@devongunsmith4698]

Yes very similar. More metal to remove in general.. but very similar process.

[@richardc6932]

I enjoy watching this gentleman go through the detailed procedure of each and every repair but the the amount of footage spent on reaming was a little lengthy. I got the idea fairly quickly and was anxious to see the threading process for the choke sleeve and then the finished set of barrels. I apparently misunderstood the procedure because his job was just to open the existing chokes, no sleeves.I am interested in knowing how to determine the chokes on my Webley & Scott 16 gauge with 28” barrels.

Glad you enjoyed it

Could you use the mirlon/cutting oil to remove lead fouling, light pitting?

[@devongunsmith4698]

Yes to lead fouling: if you use a drill driver or lathe to spin the rod, it will squeal like blazes with the fouling.. but it will clean up. Don’t attempt pitting. There are too many pitfalls honing pitting. You would need barrel thickness gauge and bore scope for starters

[@cjay8163]

@@devongunsmith4698 great advice thankyou, the wall thickness have been measured and are OK apparently, the gunsmith said the pitting isn't too deep, just a couple of patches of in the bores but they're black/discoloured so down to my OCD wanting them smartened up really! Thanks again

[@turbodrawspeed]

I read online that you should never rotate an adjustable reamer backwards. Thoughts?

[@devongunsmith4698]

Well, if you read it online, it must be true… 😄 what about when a reamer picks up or jams? The trick is you use lots of cutting lubrication.. I think what you’re describing is the risk of blunting the cutting edge. I sharpen mine routinely…

[@SimiPair]

The best patterning chokes I've seen are screw in types, with a conical section that transitions to a cylindrical section at the muzzle.

[@devongunsmith4698]

Yes that’s also true of the remaining portion of the choke cone in those barrels.. Guide bushes are of limited use, you have to feed them in from breech end, in order for them to function correctly. The premise of the channel, and the challenge, is to use tools readily available to the home gunsmith without a fully appointed gunsmith workshop and all the attendant tools and gear… A competent DIY home engineer should be able to carry out most jobs with basic tools.

[@snowgorilla9789]

Thank you from Canada, I assume the reamer cuts in both directions, but am ignorant on the threads ? Does the reamer miss the threaded area, or you thread later which means re cutting to a common ID ? Am a gun guy (handguns mainly) and obviously I know little of shotguns

[@devongunsmith4698]

These barrels were solid fixed chokes, hence the need to ream.. multi- choked systems only need to have different choke sleeves screwed in to achieve different choke patterns. 👍

[@snowgorilla9789]

@@devongunsmith4698 thank you, now that all makes sense

[@ronalddavis]

reamers cut in one direction only

[@ronalddavis]

backing the reamer up like he did can dull it

[@Brn-g7m]

What would the pattern deference be when using bismuth?

[@devongunsmith4698]

Comparable with lead choke schemes.. approximately.

[@GroceryGuyToo]

What brand and model # reamer did you use? Very interested in opening the chokes of my old gun choked for fiber wads…

[@devongunsmith4698]

I’ve got a video coming soon showing a honing method that doesn’t require reamers.. I keep forgetting to check the reamers details!
