Hi All
I’ve tried two methods of repair. Both successful.
First attempt involved milling out the old and fitting an old starting handle dog back to front in the hole so formed. This was held by three bolts in drilled and tapped holes through the nose cone. Once satisfied I j b welded the dog firmly into place.
Second attempt involved milling out a hole to take a reconstructed reverse dog. The hole was a few thou smaller than the dog that was accurately turned in the lathe. Heat the nose cone up in the oven and shrink fit the new dog in.
Cheers
Howard
