tried to machine titanium
onlinemetals was having a sale so I got a foot of 1/2" titanium round in
"grade 2", whatever that is. I tried it out on the Sherline lathe. The stuff makes stainless steel look like brass. Never seen anything work harden as fast, or make such nasty sharp chips that never break off and just make a brillo pad. Like the folks on the internet say, as long as you don't interrupt your cut and don't back off on cutting pressure, it's not bad at all. The real struggle is always with parting off as everythings wants to slip out of square on the tiny lathe. I measured the thicknes of the chip that came off with a HSS parting blade at 0.005 when things we running OK. I cut with "relion" cutting fluid, and got a little smoke as Ti gets hot when cutting as it's apparently a bad conductor of heat. The stuff takes a decent finish and cleans up real nice with fine sandpaper if you're real forceful. Can't wait to try to cut some threads on it. |

As a pyrotechnician, I can also tell you it's HIGHLY flammable. Keep it wet with coolant always. I've seen the aftermath of "dry cutting" on Ti, and it isn't pretty when a large pile of chips ignites! Well... it IS pretty when it's in a pyro effect, but not so much on your lathe chip pan!

For small parts, it's the right tool and it works great. I agree. I do not have a Sherline lathe, but its reputation is that if you don't try to over work it the work it produces will be good. Pencils? Why? Pens are the way to go. You make pencils by extruding wood goop around a core. Its like saying a Taig 2019CR isn't a real mill or that its bad. Its good at being what it is. An inexpensive small mill for making small parts. I made tens of thousnads of dollars worth of parts on my Taig, and it paid for my next couple machines. It didn't make any of those parts very fast though. |

I use it only seldom, but I've made some nice "microscopic" parts on it. The only drawback is that I use it so seldom, I often have to replace the O-ring belts before it will work again! LLoyd |

LLoyd My old mentor at American Machinist, Bob Hatschek, used a Unimat in the only production application I've ever seen for one. He made a little aluminum and brass gadget known as the "Hatschek Hook," a release hook for high-class model gliders. It weighed a fraction of an ounce and it had quite a bit of machining on it, all done on the Unimat. Bob sold over 1,000 of them, worldwide, to model glider competitors. It wasn't cheap. -- Ed Huntress |

For small parts, it's the right tool and it works great. At least it cancels any misconception that metal is infinitely rigid. At Mitre I acquired a Sherline and a Prazi clone from closed labs (a bad omen). The Prazi was large enough to be useful though I dislike its controls. I couldn't learn to like the Sherline for anything. It fit in a drawer and there it stayed. I can do tiny delicate work in brass better on my 10" South Bend. --jsw |

So Im more than a bit familiar with both of them. All things said..not a bad "marginally better than a toy" machine. The factory was fascinating in the late 90s. Everything was running off a military surplus generator out in the side yard. Not a lot of AC either..easy 110F in the shop during the summer months. Shaublin small machines are hardly toys. Minatures perhaps.... Shrug Gunner --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Which..is really around the bend. Sucks to be you. And according to your past boyfriends...quite well too. Im curious..why havent you and your Top taken a round the world trip (except in bed)?

Looks like you are stuck with the toy. Not sure why this sort of becoming a ****ing contest. Call it what you whatever you want, but I've been able to make all sorts of useful stuff I wasn't able to before with the small lathe and mill. Hypothetical machinery you don't have really doesn't get the job done. One guy I know uses pre WWII looking old leather belt driven machines to make parts for export to Germany. It's an eye opener in what can be made with what might be considered (they're real pretty though) laughable tools. |

However when you bang up against its limitations it's time to think about a larger machine instead of fighting its inherent weakness. Unfortunately I don't know of a better currently available hobbyist lathe to step up to. I bought old American iron with its problems of scarcity, wear and abuse. My first lathe, a 6" Sears/AA, was NOT a good choice due to its easily bent 1/2"-20 spindle nose. --jsw |

It's an eye opener in what can be made with what might be considered (they're real pretty though) laughable tools. I have a 1938 Bridgeport round-ram that I converted to CNC. I make parts that are exported all over, as well as sold domestically. One of my major customers is L. S. Starrett, they use my servo amps in their high-end Force Measurement Systems. I don't even want to KNOW how much they get for those! (The part I make for those servo amps is a mounting bracket, machined 1/8" aluminum, bent and then rigid drill-tapped on the Bridgeport.) The rest of the servo amp is a printed circuit. Jon |

LLoyd Leave the "safety cover" open, and the "O" rings will run cooler and last longer. Which Unimat is this which has a safety cover? I've used the early ones (two models, but the same steel rods for rails) which had the pulleys out in the air -- ready to grab a careless fingertip. :-) Trying to remember those models -- DB-200 and SL-1000 IIRC. Yep -- verified. Enjoy, DoN. I have the Unimat 3 which resembles an actual lathe since it has a cast bed with V ways. --- Gerry :-)} London,Canada |
