1. Original prototype 750w upgrade install and how to do it.
Sold complete with all the adapters required to install in the original motor location.
This allows for complete reinstall of all threading gears and auto feed systems.
Also incldes controller stand and tach housing as seen in images.
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 on the fly is simple; Just push the blue latching button.
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 200 RPM
Highest speed this one produced: Motor 4,500 RPM.

Note: Check the photo of the yellow lathe in this listing.
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 too long, too short or most common just a few thousands too small in diameter where they will pull and damage threads.
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.
