Sonny, if you could take a close up picture of the crown and post it here, it would be easier to comment.  The answer to your question is "yes, you can recrown a barrel right on the rifle" by hand.

These have been posted before, it has been a while ago.
 
The cutter is a old broken center drill split and shaped.

I cross drill [45 degree] a pc of brass [360] and set screw for the cutter.

Thread the stem for some type of knob to spin it with, also thread the body for an adjustment nut.

Use some sort of bushing with clearance for the cutter.

I have made them from .32 to .875 diameter..........simple and work great.

The crown is always on center with the bore.

Lynn,

Glad to hear they work for you!

It helps to have use of a lathe, but I made the 50 cal in the bench top drill press.

I use a round carbide cutter available thru MSC. They come in different sizes that will fit any caliber.

That cutter looks real slick but all I have used for years is a ball stone. Willie Boitnot (Now there is an old time gunsmith) showed me 25 years ago how he did them. Just a round ball stone turned in a hand crank drill. Start straight on and the revolve around slightly as so the same grit of the stone don't scratch the in the same spot. Oiled of course and it takes longer to find the hand drill in the drawer than it does to cut it the crown. 1 min tops.

  I do like shingler.  Then I follow with a chunk of brass rod of the same diameter as the stone, chuck it up and turn the end down to a sphere.
 Load this up with compound and polish the crown you've made with the rock.
  You can also use your thumb with some fine paper, works very good.

After seeing bs2's crowning tool, I turned one out on my lathe to crown my smoothbore. It made short work of cutting the crown.
