I am making pencil boxes for my Grand Kids teachers. I need to drill a 1" hole, 7.5" deep. My protocol is a modification of the technique written up a year or so ago in the AAW American Woodturner magazine.
When using a 1" forstner bit with an extension the bit wanders a bit so I bought a long 1" wood auger bit. I chucked this bit up in a Jacobs chuck and with the lathe at about 50 rpm tried to bore a hole in my spindle for the body of the pencil holder. DASTER! The screw on the end of the auger sucked the bit into the wood and spun the chuck out of my hand and the tail stock MT taper. The tail stock quill now needs to be reamed smooth again.
I Googled #2 MT reamers and they are priced all over the map. You can find them for anywhere between $15 to over $100. I hope to only have to use this reamer once. (my PM 3520b is about 10 years old and until now I have not needed one. With any luck it will be another 10 years and my Oncologist in his wildest projections won't give me that long).
What do you machinists out there recommend for a one time job that will produce quality commensurate with PM specs? Also appreciated would be helpful tips about how to do this job. I admit to knowing next to nothing about using reamers and learned long ago that when you don't know what you are doing, you consult someone who does.
On another tack, do you-all think that griping the Jacobs chuck with a large vice grip pliers while my Grand Sun feeds the tail stock quill would work? Would filing the threads off of the screw on the end of the auger work, or would it just wander worse than the Forstner bit? Maybe speeding up the lathe so the screw just tears out would work? Suggestions are welcome.
Thanks
