Drills

[salmon]

I use a Foredom that, like Jeff, is on a pole on the bench. I have a couple of hand pieces, but my flexible shaft hand piece is my favorite. It uses a pedal to vary the speed and I cannot imagine not having that ability. The quick release chuck holds 3/32" shaft bits. Returning to topic, I have a set of drill bits from 3/32 on down to ity bitty (that stands for it is small and I do not remember the size) that has the 3/32 shank.

Would it be possible to see a pic of the various tools being used in action? Like a demonstration of technique that I can learn from?

Thanks

Is this the self tapping bit that you are referring to?

And you use these diamond burr bits to enlarge the hole after drilling a pilot hole? Or do you also use diamond coated rotary disks to trim out two holes to make an oval?

When working with fiberglass hulls, I only use diamond burs to make the initial, rough openings. I usually select a bur that has a diameter of 1/2 to 3/4 the smallest dimension of the hole to be opened. For example, if I am working gone those pesky U-boat casing slots and they're 5mm by 15 mm, I like to use a bur that is 2-3 mm in diameter.

Once I have the opening roughly cut open, I then use a series of miniature files to open to the actual desired dimensions. Again for U-boats, that would be a flat and round file.

I mentioned earlier that I use of the Dremel Flex-Shafts connected to my hanging Dremel tool. Here's an example of one of the available types:
