he makes it all look super easy
the jam chuck is a simple concept but sometimes not so simple to implement i need to practice on that i am thinking the jam chuck wood should be softer than the material that is turned |

And if you go a tad undersized, you can "recover" by putting a paper towel between the chuck and bowl. I learned that off a Raffan video. It's always good to have the tailstock engaged of course, until the very last... -- Kevin Miller Juneau, Alaska http://www.alaska.net/~atftb "In the history of the world, no one has ever washed a rented car." - Lawrence Summers |

In that case you would cut the tenon on the stub so that the piece fits over it, rather than into a hole. Other times, it makes sense to turn a recess in the jam fit chuck and put the piece into the hole as you describe. It just sort of varies with the application. The idea is essentially a friction fit, either holding on the inside or the outside of the piece depending on what would give the best grip... ....Kevin -- Kevin Miller Juneau, Alaska http://www.alaska.net/~atftb "In the history of the world, no one has ever washed a rented car." - Lawrence Summers |
