I took the lathe apart, and found the hi/lo gear in pieces. It was a little tricky getting it apart, but I ordered the new gear today, and hopefully I will be able to get it back together in a week or so. Mike

My harbor freight mini lathe spindle suddenly turns free as the motor is running. I took of the end panel and no gears appear broken. How do you get to the spindle that holds the chuck? I think a pin might have sheared off. Thanks! Mike

I'll try this again, the video of the thimble

I hope this works!

My thimble! It runs on lung power.

What is the best way to make multiple passes with an endmill in a slot and have consistent edges? I had a 1/2 x 1/2 brass rod that i needed to make a notch in one corner. I needed the remaining material to be .06 on each edge. I needed to make multiple passes to get the correct depth, but i had...

Sorry, I need a 3/16 hex brass rod. Thanks, Mike

Does anyone know a good source for small quantity metals? I need a 3/16 brass rod, about 12" Thanks Mike

Thanks for all the advice. I took the lead screw off, and sprayed the bearings with wd-40. I then wiped it dry, and put some high speed oil on the bearings. After working a while, I was able to make it turn properly. I guess I wasn't getting enough oil on the bearings.

Help! I was turning a crankshaft for a steam engine on my harbor freight mini lathe using the auto feed. Suddenly, it stopped feeding. I took off the cover to find the plastic gear was all chewed up where the key holds it to the shaft. I tried to turn the shaft with the allen wrench, but it...

I am building the Jingle Bell engine from the plans on this site by Paul Jorgenson. The problem I have is the Cylinder in the plans had no dimension for the slot that is cut through. I estimated from the drawing that it was 1/2 the depth of the bored hole. After assembly, with the crank at top...
