It cost lost to make gears quite. Even the chain and noch type belt will a lot noise at higher speeds. When purchasing a mini lathe I want v- belt or poly-v to keep noise down. I did know belts slip too. Dave

I have try freecad I think something missing. I have used Autocad since 1995 still using today . Install Autocad 2000 on my laptop with Windows 11 64 bit. I have the free version of TruboCad . It works great too. There probably something I just do not know about FreeCad. It runs on Windows...

I just purchased a sandbaster from Harbor Freight to match my air compressor. I built a real nice cabinet use a shop van for dust collection. It to big when downsized. I was planning on just getting a clear storage box fof cabinet. Today I use regular sandblasting sand from Home Depot and...

It always comes down to weeks link. With mini lathes it is belt . All torque need from motor is so belt just slips. Manufacturer will put bigger motor for advertising Dave

Looks great I have look at solar steam . The Titania on third engine use water at 185°F [85°C] At this point you could store water in a inclosed pool. Dave

I agree 👍 Dave

There three different ways I look at one was 1) to mill part carriage and add a exstension to screw 2) Add a exstension to the screw, modifie the old one and and move nut. 3) make new screw and move nut. I have made other cross slide screw pass it not hard to and all one piece and move nut...

This first year with mini lathe working very well. Add good tool post and add 1" travel to cross slide. Dave

That is very true with brush motors. Lower speed great torque. The AC or brushless is more consistent torque. What do have how much the torque may or may not increase. By graph I found on internet it is nothing. That would problem with larger lathes but they gears. With mini lathes...

The cycle for 4,500 rpm is 75hz Dave

Here is photo of a Cat forklift had a little twist. I am taking photo The forklift weighted 35,000 pounds before the counter weight is add in back. The forks are 8 foot [2.44 meters] long and 3½" [89mm] thick . The engine is a Cat 3208 Dave

This about best graph I found for the brushless motors . For speed from 100 rpm to 2,000 rpm or motor speed from 300 rpm to 6,000 rpm is a frequent of 5 cycles per seconds to 100 cycles per seconds. The graph is used for 60hz motors up to 120 hz or cycles per seconds. Top motor speed 7200...

I use to restore Catapillers for hobby. I found model size was easier , cheaper and less space need. But cat could get ground ready for potatoes 🥔 and vegetables. Dave

Sounds great work Sounds a lot safer work 23KV with pencil. Dave

I like cat I have rebuilt a few past . 45kw using a 3304 cat engine it smaller than you working on but just side projects. Have D8 cats Dave

How lathe running with new motor working on low speed? Dave

They not hard to make. I have cast iron , brass and pipe. Cast iron last longest and pipe is cheapest. I just ring the cut ring apart on one side. There should a little calculator or just eye ball. Dave

I think most is thinking a pm brush motor is a cheap motor. The brushless is lower cost to manufacture. Three phase motors are lowest cost to manufacture of all motors. But they ard not lowest to buy. Typically they use high quality bears and wire. Dave
