SuperSoft Jaw Remix (Ridiculous Egg Example)

by: Andrew Grevstad

My first SuperSoft Jaw movie was a good example for thin parts. But it neglected to show another strength – securely holding on to delicate objects for light machine work. I’ve brought along Tormach’s good friend Ed as a special guest star for this movie. Ed is a tinkerer and inventor here in Madison. He’s been involved in small CNC machines for since the 80’s and actually did the majority of the design work for the SuperSoft Jaw product – taking it from an off-the-wall idea to a useful hardware kit.

Ed kept mentioning that he could use SuperSoft Jaws to firmly hold an egg in the vise, so I asked him come over and show us how it was done. The “Egg machining” portion of the video, however, is completely self indulgent. The long version of the clip below shows how the setup is done:

From very limited experience, I can tell you that the best way to cut Egg Shell is High RPMs and slow speeds – I had best luck with our Kress companion spindle kit. And if you plan to use a Right-handed endmill to scramble, run the Spindle CCW. That’ll keep the egg inside the shell – it kind of works like an immersion blender.

Here’s the last two minutes of the movie again. Straight to the Punchline, for those who like to skip to the back of the book.

The video cannot be shown at the moment. Please try again later.

    Ha, digging the facial hair. In any case, I really like the blogs Andy, makes me want a Tormach with all this company support.

    Thanks Jason, glad you enjoy the blog. Still trying to convince my wife on the scruff, however :)

  3. So with the right tool 2 I could scramble my eggs in the shell, yes!

    Hey Andy, I’ll take mine scrambled

    I like this idea and have some of this material and am considering buying the kit. However, the examples you show have been the knife and this egg and neither were mounted very precise. I would like to see something put in the vise with this material and how you align it perpendicular with the machine? I assume you can lay the part on the pins, that means the bottom of the part have a least a datum surface that can be used.

    Randy, funny you mention that. We have one final Super soft Jaws movie that shows a technique to reference a part to the top of the jaws. Look for it in the next week or so.

    Sweet! Thanks Andy… Awaiting this video:)
