Can't say for sure if the it will fit but any I have seen look the same.
My Millport is the same as my dads Bridgeport, the people at Millport told
me they had sold psrts to bridgeport owners looking to save some $$, but
they don't offer much now.

Are you going to sell the Nichols or Van Norman?

I don't think I will part with the Van Norman. I have two Nichols millers so
probably at least one has to go. I do too much buying and not enough
selling.

You bought a Bridgeport base?? I had a guy up here that had a whole J
head for $200, it looked to be in good shape. Step pully but I prefer
that myself.
How are things in the Island? I moved the 14 SB into my shop and put 1
of 3 lathes up on ebay, I hope to get things cleared out and back to
making stuff in the next month.

One is available for $200, locally. Seems to be in reasonable shape,
couple holes in the table. I have to verify that my head will fit. Is the
knuckle the same on all of them?

Any source, other than ebay, for vari-speed J head clone parts? Do
the
clone manufacturers also get ridiculous money for sheaves, etc.?
I've
tried google but without much luck.

Thanks, Marty. Their website seems to be having difficulties, I was
able to
find their product breakdowns at this link:

I found a headless Bridgeport I'd like to put one of my clone heads
on.
Unfortunately I'm missing the vari-disc and spring assembly that
rides on
the motor shaft. Converting to VFD speed control seems like a good
option,
but will still require a way to drive the belt on the motor side,
which
currently only has the one cone shaped side on it.



If you can come up with a simple way to adjust the center distance or
install a tensioning idler, you might consider installing v-belt
pulleys, or step pulleys, on both the motor and spindle. I've owned
both
step pulley and vari-speed mills with VFDs and prefer the step pulley
setup. Much quieter and less trouble and plenty of speed range from
the
VFD without much belt switching. Regular v-belt drives are also more
efficient than the vari-speed Reeves drives.

My 1HP step pulley BP spent most of the time set on 1000RPM. My
current
Supermax 3HP mill is almost always on 900 or 1800 RPM, and I could
probably get away with just the 1800 RPM setting, giving a direct
spindle speed readout on the VFD, if I put a cooling fan on the motor.
The VFD is limited to 6 to 90 HZ, but I avoid running below perhaps
30Hz
for long periods to avoid overheating the motor.

I like the step pulley idea. The shaft on the motor is pretty beat
where the disc used to ride, so I'm not sure how well a replacement
would work anyway.
