The horsepower improvement is incredible.
Kinda like replacing the small block with a big block in your Mustang/Camaro muscle car. Just pure power, so much so that you will never use all of it.
This system provides full power at any speed and that includes Spindle RPM's as low as 50 RPM's in low gear. You may want to consider the high low gears inside the head and at least lube them with a high end sling free grease.
Motor and spindle speeds + Reverse:
The motor speed can be
programmed
and or full range can be achieved with just the speed control rotary knob on the
controller
:
Speed control
programming
only requires a few easy steps.
Reverse is simple, just hold the yellow button for a few seconds.
Programming
includes the ability to set bottom and top RPM range separately. In other words you can program the system to run the spindle at any speed or range of speeds you choose (see below).
Slowest speed achievable: Motor 300 RPM
Highest speed this one produced: Motor 4000 RPM.
Motor Specifications:
Watt:           750  (
1.0057665666 HP)
Voltage:      110V
HZ:             60
Torque:      10 N.M.
RPM:
100 to 4,500 RPM
in 100 RPM increments.
Note: Manufacturer recommended 500 to 4,000 RPMs
My personal testing results: This motor runs best between 300 and 4,500 RPMs.

Mini Metal Lathe 1 HP Servo Motor 750 Watt Computer controlled with threading and gears"
Same username The Custom Crafter. I will do a video on this system as soon as I can find the time to do it.
This listing is for a fully alpha tested system.
System includes:
A new 750 watt motor like the one seen here in photos.
Motor will come with the motor mount installed This will require adjustment to fit your lathe. It will also come with the small timing pulley installed on it using a 4mm key-way and main shaft nut.
A new control computer with internal speed control like the one seen in photos.
This control unit is modified by The Custom Crafter to include a thermal overload system with reset button. (see photos), make note: Color of the reset button may be black or red and the rotary speed control knob may be white or red as well.
The Custom Crafter made in the USA motor mount. (installed on motor, see line 1).
Mounting hardware includes thick washers and grade 8 nuts.
One aluminum intermediate shaft timing pulley machined by The Custom Crafter to fit (see photos).
Note: This timing gear is prototype three. I still do considerable filing by hand to insure proper fit and you will see file marks.
One aluminum motor timing pulley machined by the Custom Crafter to fit the motor (see photos).
Comes preinstalled on motor (see line 1). This gear is the
result
of 100's of already in use systems. It is the final design and is flawless.
A new L050 1/2" wide timing belt.
A custom machined belt cover plate to allow for the larger belt.
The control computer (driver) comes programmed to optimal performance settings for this lathe.
Programming instructions and fault codes are also provided by The Custom Crafter. Includes
recommended settings.
Package will not include basic written assembly instructions yet. There will be a text number for direct assistance from the custom Crafter.
Assembly requires some technical skill to include minor machine work.
Note: Check the photos in this listing. See the red lathe (image 11). If your lathe has holes instead of the normal slots, this motor will not fit without your ability to slot the cast iron lathe bed. Additionally if you return this item for this reason, you will pay shipping
both
ways.
You will need metric and domestic allen wrenches + a 13mm/1/2" deep socket and ratchet.
Some shorter/longer/better quality allen head metric bolts (not included) may also be required, especially to clear the timing belt as the belt cover is machined thinner to allow for the larger belt.This means do not over tighten and check first to make sure your bolts are exactly the right length and thread. This is because many manufactures use inferior bolts. these inferior bolts will be slightly to long, to short or most common just a few thousands to small in diameter where they will pull and damage threads.
Notes:
This system has so much more power that it becomes tempting to see just how much you can cut in a single pass. Do not do this because the rest of the mini lathe is not built strong/stable enough for this kind of abuse. If you jam it, you may damage the lathe to include broken cutters, parts and the control unit.This is abuse and no refunds will be issued for damage caused by abuse.
All lathes are dangerous, increasing the
horsepower
increases this danger.
