55955Re: Boring Fails
- Dec 1, 2013I have been boring my flutes for several years now. I too struggled with
the drill bit drifting off center. I researched and discovered a drill
bit designed to minimize drifting. The bit was developed for rifle
boring or deep hole drilling. I also discovered a high price tag if I
wanted to use for making flutes. Looked a little more and found there is
a woodworkers version of the bit. It is used to drill the hole in turned
wooden lamp to run the electrical cord. The bit is called a Shell Auger
bit. I purchased one from Wood Workers Supply for under $20.
The bit is used on a lathe and is feed through the Tail Stock Holder.
The trick is to first drill a 3/8 inch pilot hole. Once you have the
pilot hole you can use a long Ship Auger bit to dill the bore. The feed
screw on the ship auger bit will follow the pilot hole. I use a drill
press on a Shop Smith to drill the bore, but a standard drill press will
work. I don't see why you couldn't use a regular hand drill and clamping
the blank to a workbench the bit will still follow the pilot hole.
This a very brief summary of how I bore my flutes, if you have any
questions I will be happy to go into more detail for those interested.
