Lead time is up to 5 days:
We have very limited stock on the motor mount bracket. Often we have to make parts when orders are received. Your purchase places it in the lineup to build and ship. Currently it can take 1 to 4 days before it is complete and shipped.
Custom Made When You Order:

Fits Many Mini Metal Lathes.
Sold complete with all the adapters required to install in the original motor location of your spindle drive mini metal lathe.
Allows for complete reinstall of all threading gears and auto feed systems.
Fits mini metal lathes that the drive belt goes directly to the spindle gear.
Does not fit mini metal lathes that have an intermediate shaft (high/low gear). To fit these you would need to purchase one of my systems designed for two speeds. See our Mini Metal Lathe 1 hp Servo Motor 2 speed kit
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 200 RPM's
Motor and spindle speeds + Reverse:
The motor speed can be programmed and or full range can be achieved with just the speed control knob:
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 100 RPM = Spindle 60 RPM.
Highest speed this one produced: Motor 3,500 RPM = Spindle just over 2,000 RPM's.
Note: it is not recommended to spin the spindle any faster unless you upgrade the factory installed spindle bearings.
Motor Specifications:
Watt: 900 (1.2 HP)
Voltage: 110V
HZ: 60
Torque: 11 N.M.
RPM: 200 to 3,500 RPM in 10 RPM increments.
Note: Manufacturer recommended 300 to 3,500 RPMs
My personal testing results: This motor runs best between 300 and 3,500 RPMs.
Ratio of belt drive:
1.6 to 1 (motor turns 1.6 revolutions to every revolution the spindle turns)
Motor 300 ~ 3,500 rpm = Spindle 187 ~ 2,187 rpm.

A new 900 watt motor like the one seen here in photos above and on you-tube. 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 5 mm key-way and main shaft nut.

A new 2026 control computer like the one seen in the above photos. This control unit is built by The Custom Crafter to include:
A. Built in Thermal overload protection rocker style switch with reset function. See photos, make note of the orange power switch with the word RESET. If your switch is red or if it does not say reset, it does not have thermal overload protection.
B. Software based jam protection.
C. Internal speed control rotary switch.
D. Reverse on the fly function.
E. Power went out safety circuit.

The Custom Crafter made in the USA motor mount. (installed on motor, see line 1). Includes thick washers and grade 8 nuts.

The Custom Crafter made in USA spindle bearing head adapter (see photos).

The Custom Crafter made in USA spindle spacer (see photos).

Package may not include basic written assembly instructions.
If this is the case, ask by contact form and we will e mail you a copy in Microsoft dox format.This will include 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. 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 have to cut the die-cast gear housing to allow additional room for the larger timing belt. (see photos)
this can be done with a hacksaw and a file but a pneumatic cut off tool or die grinder will ease this job.

A spreader wrench is a big help but this can be managed with a hammer and punch.

You will need metric and domestic allen wrenches + a 13mm/1/2" deep socket and ratchet.

Some longer allen head metric allen head bolts (not included) may also be required, especially it you over tighten and strip the factory bolts provided with your machine.
If you have a mini lathe this is the best upgrade for the money by far.

Great Kit A+.
