No, ya got lost somewhere Dan. The question at this point is how do you
resize a forstner bit by dressing it, and how could it possibly be the
ideal bit to resize.


Turn down the outside, or grind down the outside. It is a relatively small
height, and all solid, except for one or two small areas.

Thanks Geoff, that is the question on my mind too. If you could even find
one that was 11/16, you would have to pull .030 per side off of it to get an
oversized 5/8. If not, you would have to pull .060 per side off of a 3/4. I
don't see how you could do it without a tool grinder.

If you own a bench grinder, drill press or dremel equivalent make a
bracket out of sheet metal, phenolic or hardwood to hold the tool. It
sounds a tad Rube Goldburgish but it can be done. I made a few for
grinding lathe tools.

In the case of a rotating bit you need symmetry as much as size. It
seems to me you coulduse a wood block drilled to accept the tool shaft
at one end and drilled to make a pivot point at the other. A simple stop
like a machine screw could serve as an adjustable stop.

Visit a machine shop some time, you'll see some rather clever widgets
made for a one time use. You never know, they might have exactly what
you are looking for.

Yep/ That's the type.

Make a widget to hold a small angle grinder on its side, with a pivot and a
screw for advancing the grinder a bit at a time. Make it so that it will
work clamped to a drill press table.

Put the drill bit in the drill press, and push the bit up and down past the
spinning grinder. Advance the grinder a bit at a time, and stop to check
the progress often.

It works. I've done it before. I am a bit "Rube Goldbergish" at times.
That comes in handy, for a homebuilder.

Of course, if you know someone who works in a machine shop, he could do the
job in a tenth of the time. Where's the fun in that, though?

Torpedo juice was supposed to be alchol. Ref:

Don't you remember Buster Keaton drinking torpedo juice in the old Muscle
Beach Party movies.

The old torpedoes did burn alcohol. The running gag in McHale's Navy
TV series and many movies is they would drink the stuff. If memory
serves it wasn't safe to drink since it was wood alcohol. The problem
with alcohol burning in torpedoes is you get wakes that can be seen
visually and heard by hydrophones. That's why they went to batteries for
electric drive. That and gyros could be electric instead of pressure driven.
