Mini Lathe 3HP Motor Upgrade..... (Yep 3HP)

Video Description

G'day everyone, In this video we'll take thing up to 11 with the mini lathe by giving it the most powerful motor that I could find that would sit behind the lathe. That being a 3HP/ 2.2kw motor. To put that into context, that is 6 times the power that the lathe came with from the factory, and probably a whole horse power more than the biggest lathe that I have used. Even the big 300mm swing lathes don't come with 3HP. And my goal is to bolt it to a small 7x lathe. (Sieg C3 7x14 Mini Lathe) If everything goes well, it will probably be the most powerful mini lathe in the world. My goal really is to be able to slow down the lathe so I can properly use reamers adn drills without the fear of burining them up, which is what would happen with the current fixed speed set up. In this video I will bolt the lathe to a 20mm thick piece of steel plate to add some rigidity to it. I will also machine new pulleys for the new drive belt. I will also machine a new mounting hole for the headstock. I hope you enjoy the video. #machining #minilathe #lathe timestamps 0:00 - Introduction & 3 Horsepower Motor 4:17 - Strengthening Plate 5:54 - Machining The New Pulleys 10:19 - Welding The Motor Plate 12:11 - Adding An Extra Headstock Bolt 12:52 - Machining A Pulley Retaining Cap on The Milling Machine 15:01 - Wiring Up The Motor And VFD 16:43 - Test Cuts
