Now is the time to learn to use a cutoff tool instead of a hacksaw  A lathe is a wonderful tool to make tools  BTW- WD-40 or kerosene is good for turning aluminum. Do not use motor oil for any kind of cutting or drilling. Use actual cutting oil for steel that is available from McMaster or your local hardware store. Cutting oil can be collected, filtered, and recycled, so use a drip pan. |

Make a toolpost holder for your foredom! Double rotating tools of destruction!

I thought about a parting tool earlier, but then I had other stuff to make so I just worked with what I had for the moment. I thought about a rotary tool holder as well, but I don't know if I'm in a big rush. After using the lathe with 1 new handle, I would really like to get that done next. If you have the time and inclination, I would gladly pay for two of those "bullets". I think they would make some pretty cool key chain trinkets.       |

A new product for you, keychain trinkets! Angle drill a hole to pass a tiny keyring. Use a center drill on the 'bullet' end to make them look like hollow points. The aluminum ones look like silver bullets for werewolves and vampires. Now you need a CNC mill to engrave headstamps on them. You can never have enough tools. These things would make good practice pieces for cutting to an actual dimension to match known ammunition dimensions. If you miss, no big problem, and you will learn how not to miss Practice, practice, practice...  EDIT: BTW, I heard somewhere about using small carbide tipped saw blades for cut-off tools. Multiple cutting surfaces, just rotate a 'notch' for a new one. Left and right cut blades also. Some methods listed with a google search for: circular saw cut off blade in lathe The one I saw used a small diameter saw blade for multiple cutting edges but I am not seeing it. I will have to keep looking. Hacking out a blade tooth does not seem reasonable to me. Metal cutting blades would be needed, the wood cutting blades have too much rake. The blade centerline in a tool holder can be adjusted for the proper rake angle. |

Do you guys save the tailings (?) if it's aluminum or brass? I would think over time the weight would add up to some nice pocket change.

I've been grabbing the large stuff and tossing it in with other aluminum and the rest gets shop vac'ed. I don't think it'll add up to much of anything. I get something like $35-50, depending on the prices at the time, for the Mazda truck piled up with bags of crushed soda cans. |

I wanted to make another replacement handle since I liked the first one. I didn't get too far before the lathe started to rattle. I pulled the front cover off and one of the studs was broken off and the other was loose. I think the broken stud has been that way since I got it. I found the end of a stud with a nut on in it the shipping crate and never saw where it was from.  I took the bolt cover off and noticed a bolt stuck to the motor. Not related to the issue, just another example of the level of care and quality control from the factory.  Then I found what looked like a key or key stock lying in there.  The set screw was loose on the motor pulley.  Then I saw that the motor was missing the key and the pulley had spun on the shaft. It didn't chew anything up too bad luckily.   I found that one stud was not only broken, but both were bent. Can't really tell the bend in the pic, but it was obvious when turned.  I put the key and pulley back on.   I cut off a couple of M6x1.0 bolts to make new studs and got the motor re-mounted (with threadlocker) and put the belt back on.   It worked OK again at that point, so I put it mostly back together and then finished up the other handle this morning. If anyone else gets one of these, make these handles with bushings. It's a good practice project and an improvement in feel/use of the lathe.  |

Its always a good idea to go over any china made product to tighten down the screws.

You gonna do the motor mount mod eventually?

That looks like a much better idea John. |
