Here is another way to look at it. If we take a simple solid flywheel disk of mass m and radius r we have a moment of inertia as mentioned:
I = m * r^2 /2
Now lets cut a small disk of radius k*r out of the center of that flywheel where k is a number between 0 and 1.
For example if our small...
I have never sharppened carbided drill bits with it but I use it all the time to sharpen those cheap chinese boring bars that I sometimes use. I just take the cover of the DD and stick the boaring bar into the small diamond wheel. I have sharpened about 35 boring bars with it several times and...
Maverik that is a great looking tool. I have a few questions if you don't mind.
1) What (if anything) stops the plunger from turning?
2) What is the purpose of the little ledge shown on the left half of the pluger?
3) What is the purpose of the shallow slot seen on the right hand side of the...
Yep that sure helps. Perfectly clear now. But now I wonder why I would want 45 degree instead of 90 degree. I wouldn't be able to turn to a shoulder. What is the advantage of the 45 degree angle?
Very interesting. Made me think ... suppose you used the setup as metioned for step 1 and then for step 2 instead of using the other edge of the square you placed a flat surface against the edge you just checked (a 1-2-3 block or parallel) then checked against the back side of that. This way it...
Very nice! I have thought about making exactly the same thing. I wasn't sure about what steel to use. I didn't thing the threads would be strong enough using just plain old cold rolled - those screws need to be tight.
Hey Bob - I love the conversion. I am wondering why the motors are geared down so much. Most of the direct coupled stepper systems use around 400 0z-in motors. You are using around 800 oz-in servos and gearing down by what looks like abour 3:1 giving about 2400 oz-in torque to the lead screws (I...
