What about the compressors for air shocks? Check for a Gabriel Hijacker pump.
I suppose everything is now made in China.... GRRRR. Maybe eBay.

The fuel injection band clamps might be another...

Can you use an inner tube?

You can easily measure the torque at whatever rpm you want to.
Add a disk to the motor, and wind a string around it like a windlass. The string is supporting a weight, and you are holding the top...

And in response to the 4'th axis wrap software option...
I had that option on my Bostomatic. I think you used a G25, or G26 to specify the diameter of the part you were going to work on. Then you...

Thanks, this helps illustrate what I trying to explain. If you are cutting on the rim of a 150mm disk, and the X distance is 3mm, then the feedrate will be a LOT faster than you want. The control...

One more thing to talk about with a 4'th axis setup...
I want to shown wrong here.. Someone speak up on this point.

Any CAM software that I looked at that supports 4'th axis work does not support...

Well, it all depends on your controller doesn't it?
I can write:

N300 G01 A720. X1.0

And get two revolutions of the table.
What that does is "wind up" the table (or the control as you see it)...

I just ran a job on the 4'th axis.
Every machinist will have a different way to touch off a part. Some will go on a holy war to convince you that their way is the best. It really depends on the...

Basically the control doesn't know what the feedrate is for a rotary since it depends on the diameter or radius of where the cutter is in relationship to the axis of the rotary.
So, how do controls...

If the stepper controller is edge controlled, you are in...
If not, you can generate a pulse from the either the A or B signal and use the other signal for direction.
Draw it out.
Neat huh?
Pete

If you had a ball screw on the X axis, and it was a stepper (low cost) drive, why couldn't you use an encoder for the X axis handwheel?
Curiously, an encoder can generate step and direction...

After it is done, you can set it up with the two tires on milk crates or similar.
Holding the tires still, rotate the center (pumpkin) section.
Measure the toe in/out of the two tires. Rotate...

The sattelite actuators that I saw.. Years ago...
were all 24 volt DC. With or without an encoder. Maybe some had
stepers.. Take a look at the number of wires from the motor.
24 volts will work at...

Are you SURE that that circuit does not reduce the output voltage?
That is one of it's interesting charcteristics... Lower output voltage.

I wish I was the inventor...
Someone once had a radio transmitter that was eating the power transformers
and input diodes. I suggested this as a fix, the diode peak currents were too
high.
It...

I specifically said to put the inductor BEFORE the capacitor. NOT as a Pi filter.
The inductor in an inductive input configuration will reduce the peak voltage.

As a Pi filter as you suggest, it...

As long as the 15 volt secondary has the current capacity,it will be OK.
They can be wired to either add or subtract.

Another way to reduce the voltage is to add an inductor between the
bridge...

If you had to Purchase the plans, aren't they copyrighted??

If someone else had to draw them up, investing their time, in order
to sell them to you, can you give them away, and stop future sales...

Check out Vector CAD/CAM
It is based on the geometry has a direction, and order.
I believe that is what you are asking for.

I always use 90 degree spotting drills, and they are also usefull as a 45 degree
chamfering tool.
Really nice looking parts with a even chamfer all aorund them!

Are you going to claim that you need to transfer $25B into the country, and
you need to access their bank acount? Maybe offer them 30% of the total for
their troubles.

Hmmmm...

Use the disk, with the string wrapped loosely around the disk. You
can spin the motor at whatever speed you are interested in, and then
when you pull the string tight, it will load the motor. Use...

Just another "vote" here, but I have never heard of a scale not in metric
units. Even when they list the scale in inch resolution, the basic scale is
actually in metric, and the inch resolution is...

That's what I did it for. The assets in the company are seperate from your

The three common solutions on comercial products are:

Gas spring. Some with a resevoir, some with a pressure regulator, that
adds and subtracts air as the Z goes up and down.

Fastest, easiest cheapest, IMHO is to get some encoders.
There are R-D converters (Resolver to Digital) . By the time
you find one, wire it up, test it out, etc. You could maybe find
an encoder...

Usually a 5 axis machine has a rotary for the A and the B axis.
The A axis coincides with the X axis, and the B axis coincides with the
Y axis. This is referring to a vertical machine.
