Folks, I have developed a drill bit for use on the lathe to drill out the
center of tall vessels. It will drill a 1 1/4" hole 36" deep in 1 minute
flat, at a spindle speed of 360 rpm. No stopping to clear chips, they are
ejected out the back end of the drill by air flow. The 36" per minute is
not a pipe dream, it will actually do it, and I have witnesses to that fact.

Now, the question is, how many people would be interested in such an item at
a price, say, of $100? My tentative plans are to make them 36" long, with
which you could drill a little over 30" deep.

Requirements a the wood blank must be supported by a steady rest, and
you must have an air compressor of moderate-large capacity. Obviously, you
must also have several feet of space at the tail stock end of the lathe.

If you might be interested, e-mail me. If I get enough replies to make it
worthwhile, I will do a production run of them.

I'd like a length of 10", with a price under $20.

I would be interested in something in the 18-24 inch range. I would be
willing to pay $50 or so if it does what you say and is fairly easy to
sharpen.

Your statement is interesting and may be of use when doing mass production
or other work.
Your best bet is to give several live demonstrations of your drill bit. In
some instances some designers will give away or have on loan tools to some
users for testing and collecting the feedback's.
As for what price should you ask a value analyze is the norm to determine
its selling price. As a rule its functional to do a present value analyze.
That is find out the cost of using that tool for a number of years and bring
it back to today's value. To do this you need a R&M study (Reliably and
Maintability).

Check out timber framers. At $100 they would grab it in a hurry.

==============================

I've seen some of the other things James has built in the past (pick-up
towable lathe, Keep it Simple Stupid toolrests, and other shop tools) as
well as his large hollow forms, and his demos throughout Central Texas. If
he says it will do it, I'd believe him.
