Mini Metal Lathe 1 hp Servo Motor 115V 750W Kit 2 speed Grizzly Harbor

1 HP 750 Watt Computer Controller and Matching Servo Motor for two speed Mini Metal Lathes. See my store for a different system that fits single speed spindle drive mini lathes. The 2022 models are here. I still need time to update photos. Fits: Has been installed  and tested on the below models. May fit others. Grizzly G8688 7" X 12" Two speed and only versions with high low gear. Klutch (Northern Tool) 7" X 12" Two speed and only versions with high low gear. Harbor Freight 7" X 10" Two speed and only versions with high low gear. Harbor Freight 7" X 12" Two speed and only versions with high low gear. Harbor Freight 7" X 14" Two speed and only versions with high low gear. (see below) 7" X 14" Two speed. (see below) About  Grizzly G0765 and all 7" x 14": This lathe has a different belt cover. It is very close but not the same. Other 7" X 14" two speeds likely have this slightly different belt cover as well. for now I would suggest asking for a price without the cover and plan on machining your own cover. Sold complete with all the adapters required to install in the original motor location of the above 2 speed mini metal lathes. This a llows for complete reinstall of all threading gears and auto feed systems. Each one is custom built when you order. When the build is complete, it will be tested for 20 minuets. Any defects found during testing will require a complete new build. This insures you likely will not have to deal with returns and exchanges due to manufacturer defects. All parts required to build are In stock. That means if it is listed as available, it is because we have enough parts to build at least two.  We also stock extra parts in case of  warranty .  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. See it (prototype 1 from 2 years ago is a 7 X 14 single speed) running, disassembly and programming on You Tube search for: " 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 2022 control computer with internal speed control. This control unit is built by The Custom Crafter. It includes a thermal overload system with reset function. (see photos). Make note: Color of the reset rocker switch is orange or green . If it is not, it does not have thermal overload protection. 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 anodized 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 anodized 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 new 2022 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. Written assembly instructions. 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 too long, too short or most common just a few thousands too 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. It is your responsibility to insure fit and proper application.
