Sir
As a hobby wood worker I have a project that I am trying to do. I am in hopes that you might have suggestions that will help me so I don’t have to invent the wheel for the100th time.
The project is to build some handles that have a round tapered hole in the center. The piece is 7-8 inches long and 1” in diameter. The hole in the center needs a taper of about 5/16” to 3/8”. I will to turn this piece to the 1’ diameter on the wood lath. I plan to build the wood block from glued up pieces that I have. My problem is how to get the hole in the center nice and round and a nice straight taper that I can vary as needed. The completed piece will then be glued on a fiberglass rod.
If you have any suggestions for any of the steps I would appreciate it very much. If you need any other information just ask.

Thank you
Jerry

I think I'd start with 4 pieces of wood, each 2" long. I'd drill a 5/16" hole through each piece lengthways then use a rat's tail file to make the taper -- sliding each piece down onto the rod as I go until all 4 pieces were in place.
Glue them all together on the rod and when the glue has set, transfer the whole piece to the lathe and turn the outside to round, then glue the completed handle to the fibreglass rod.

Here's one thought. How about taking a 3/8" diam. spade bit and grinding down the sides so that it's 5/16" at the tip. Grinding the taper evenly might be tricky. I think you'd have to sharpen the edges too, but it might be worth a try.
If you build it - he will come.
Hi Jerry,
By your description, I can't tell how deep (long) the hole must be, but you might try a tapered spoon auger, used in a bit brace. Try Garret Wade, here: http://www.garrettwade.com/jump.jsp?lGen=detail&itemID=104685&itemType=PRODUCT&iMainCat=0&iSubCat=0&iProductID=104685
I hope this helps.

Try using a tapered bit (as was suggested in another post) mounted in your lathe's tail stock at a low rpm setting.
Alternatively, you could bore it with small-to-large diameter bits and smooth between steps with either a small gouge or a file.
Regards,
It's only a 1/16" difference in 8" -- that's why I suggested doing it in 2" increments rather than try to accurately form such a slight taper over such a length.

Makes good sense to me, Ian. When I posted my reply I was a tad groggy from working a twelve hour shift at the hospital.That's my story and I'm sticking to it.Regards,Leon Jester
