A bit of a tangent: I looked through the 1931 catalog. Fascinating reading. I noticed
a device called a "vacuum tank" and I could not figure out its purpose. It seems to
be some sort of a float bowl type of device, but not a carburetor. Does anyone
know what it does?
No, no, no, it is not that old! I think that my link is closer to the correct age.
My link is from the 1940's, so my vice is 30 years newer. Those 30 make
all the difference! 110 years old vs. 80, you are trying to make it seem old.
I say this because the nut that locks the tilt is...
I have been pondering the Steelman design and I think I understand what it is
trying to accomplish. In essence, you are trading off capacitance value with
the voltage rating of the capacitor. You are doubling the required capacitor
voltage rating requirement for only needing one quarter of...
This is a heavy universal vice made by Brown and Sharp. It has 6” jaws
and opens to 3 ½”. It is very heavy, weighs 125 Lbs. It is shown in this
document on page 34.
I am asking $200. I am in Londonderry NH and I really do not want
to ship this.
To my ear, your motor never came up to full speed. It should have no trouble reaching
full speed in 3 seconds unless the motor has a heavy load attached.
This is the classic case of a shorted turn in one of the windings. The short acts like
a brake on the motor, and it can't spin up to full...
I am having some trouble understanding your measurements. In the first chart, it seems
that the red trace is way out of its proper phase position. It should be at 120 degrees
from the other two phases. This is something that you adjust by varying your capacitor
Do you have a link to...
The thing about static and rotary phase converters (basically the same thing) is
that they are trying to generate the 3rd phase by using capacitors. This scheme
requires a balancing of the phase angle and voltage by of the 3rd phase by
varying the value of the capacitors. Unfortunately, a...
I don't think that it is a 3C, the diameter is wrong: this is 0.5" and 3C is 0.65".
A Black Diamond drill grinder collet is a good bet since no one seems to
know the standard that Black Diamond collets conform to.
I have this odd collet that I don't know what it goes to.
It is a 3/8" collet with a .5" diameter and about 2" long and 24 TPI thread.
It probably goes to some watchmakers lathe.
Rather than tossing it out, anyone can have it for postage.
