hollowing question

[Dave Fritz]

I'm using the Jamison hollowing system that I got used from a fellow turner whose body gave out. The boring bar is 3/4 of an inch. I'm already hitting the entry hole with the bar so I'm unable to reach as far into the side as I'd like.

What are some solutions to this problem?

I see Monster sells adapters to be able to use smaller boring bars. Is that route advisable?

Thanks for your help.

Not sure, but it sounds like you might be in need of a gooseneck boring bar. Several people make them, I prefer the John Jordan style myself.

 

[Dave Fritz]

Dale, would the Jordon boring bar fit into the Jamison system using the adapters he sells? Do you use them in another hollowing system?

Thanks for your help.

Jamieson system

I use the Jamieson system as well and have the same problem turning the neck and shoulder areas of hollow forms. I have found several ways to get around the problem. The one I use the most is to use a homemade tool that is shaped like an "h" with a 3/16" HSS cutter. I have attached a picture of the tool. The tool is made of 1/2" steel rod from Home Depot. The outrigger sits on the tool rest and allows me to get into the areas I need to cut without worrying about the tool twisting and catching. Another solution is to keep several sizes(length) of cutters for the Jamieson system so the tool can be "threaded" into the piece without catching on a protruding end of the cutter. You also can use the bent cutter assembly that is available for the system. I haven't used it so I can't tell you how it works. If all else fails, you can enlarge the opening in the piece, which is not the most desirable option but may be necessay in some cases. Hope this helps.

My hooktools work quite well for reaching over into the sides, and don't get bound up (twisted)in the rear rest. I use Lyle's handle on occasion when I do a large piece. I

Most any tool that's designed well will work fine with that handle. What the tool does, and how, is separate from the type of handle used.

hollowing

I, too, use John's bars in my Jamison system. The nice thing about his is the cutter is held with a set screw which makes them simple to remove and sharpen.

I have John's 3/4" tools and they work very well. And I use them by hand in a straight handle or with an armbrace (Pencil's Scorpion--good package too).

If you have any captured or articulated system with a 3/4" socket, then go with the Jordan hook or straight tools. That'd be all right. There are others that would be OK too.

Yes they will.

I also still occasionally use them in an armbrace but my shoulder complains. The armbrace works well for fine cutting on the final turning. It gives better feedback feel of the little bumps and grooves inside.

I use John's tools along with the Keltons in my monster systems.

Thank you to all who replied. I'll have to get more experience, then decide the direction I want to go.
