Internal coning tool

[David Rase]

Not wanting to violate the ALR rules and clutter up the for sale post with none related comments for a big bore internal coning tool I thought I would share a couple photos of the coning tool I made years ago.  Way simpler/cruder tool consisting of hand filed brass gears and a steel frame.  I can cone down to a .40 caliber bore.

Dave, I’ve seen these but been skeered to try to make one. I gotta say your application of “crude” to this work kinda makes me squirm. Looks very nice.

At times I think I am impaired.

Can you do an explanation on how it works?

Thanks

 Really neat and nicely done. If I had one it would be on display for all to see.

Super cool.  I'd like to know how it works too.  Crude!!!!  Crude only applies to things I make.....

[P.W.Berkuta]

I remember when you first posted it and I thought it was cool then and I still think it is cool now - nicely made.

That is an amazing piece of machinery, Dave.

I seem to remember Clay or maybe Wallace making one in the Colonial Williamsburg shop, David.
Yours looks a masterpiece!

You might think it's crude. I think it is very nice, indeed.

I don't want to see it unless you're gonna start marketing them Dave.

David: is there anything you can't make and make very well? Love you work.

That is so cool David.  Functional art.  In the best sense of both words.  God Bless,   Marc

Dave that is very nice. The one that was recently up for sale was also very nice. My question is how is this better than the interior coning tool that Tom Snyder makes. Tom's is a way simpler. I have coned three guns with it , takes very little time.

For the questions on "how it works", the simple answer is "very well".

In use, the end with the coning bit is inserted into the breech of the barrel, and the tip of the cone fitted into the touch hole.  The crank or handle is then turned, causing the gears to turn, transmitting the rotational effect to the cone itself.  It then cones, or widens the interior end of the flash hole.

With most barrel steel, it does not take long to accomplish it's purpose.

David, as usual, your workmanship is very impressive.  I reckon that the Naval Academy had classes in fine machining!

That is a slick bit of work David.
