Off-topic -- replacing a smartphone battery
This is off topic for the subject of this group, but almost everyone here will be faced with this eventually, and the people here are tech-savvy folks fully capable of doing what I did, so I'm sharing it anyway.
Tonight I did something I've been planning (and to some extent dreading) for several months. The buzzards have been circling for the battery in my Samsung S10e smartphone for quite a while, but I didn't think paying someone to replace it would be worth the money. So I replaced it myself, using an iFixit battery and repair kit, plus their online repair guide. And the job went fine. I've installed batteries in electronic devices before, but modern phones are waterproof, which means the back covers are glued on with heat-sensitive adhesive. The part I feared was removing that cover, since you need to apply enough heat to soften the glue, but too much heat applied to a lithium battery could do very bad things. (The warning in red in this photo, and similar ones throughout iFixit's online guide, definitely focus the mind). The iFixit instructions for this phone are available free at and they're worth reading if you question whether you can do this job -- iPhones with glued-on backs have their own instructions but are similar (There are also many comments in these instructions, including some added by yours truly under the name "MikeT-NYC"). But I was frankly amazed at obliviousness of some of the others who did this job including one commenter who keeps calling iFixit "criminals" for providing instructions that were totally wrong -- it's fairly obvious that he or she was trying to fix a different phone and was reading the wrong instructions. Also, there were many commenters trying to fix their phones without the proper equipment, particularly for removing the cover. The iFixit kit ($38.96) includes an "iOpener" -- a microwave-heatable gel pack like the kind sold in drug stores for sore muscles, but the size of a large hot dog. Several people asked if they could use a heat gun instead. Of COURSE you can, if you're a fool. I have several heat guns, but a heat gun puts out about 500 degrees, and broadcasts the heat everywhere. The iOpener is a slim little gel tube that gets to about 150 F -- just uncomfortable to the touch -- and concentrates the heat in a thin strip, so you can nicely heat the edges of the cover without cooking your battery or the electronics. The iFixit toolkit is cheap and smartphones are very expensive. So why would anybody with a three-digit IQ blast 500 degrees onto a phone (containing a battery well-known for becoming an incendiary device) in order to save $39 on a repair kit? All in all, this kit was complete and the instructions were thorough. And so far the battery seems to be a good one. (I've "repaired" other devices with eBay batteries that turned out to be little improvement on the one I removed). So if your phone battery is dying and you're reasonably handy, go for it. |

Re: Selling Price of Used Minilathe?
Aaron Woods 9:48am? ? Agree 50-60% of new, and then add for any extra stuff above and beyond what comes standard. Make sure you show and list what all it comes with, and highlight what is over and above what comes with a lathe when buying new. I see so many ads where it just says "lots of tooling" but doesn't then show or say what that toolingSound great? I have Sterrett 17 and 16 mic new is around $800.00 but I am look at ebay and selling 50 to 250 and few goes over that price. Then shipping in $100.00. Back in 1980 I order a new Bridgeport with a 11 month waiting to get . I had a few places willing to give me $8,000 over the new price to get new Bridgeport. It is more of what the mart will give and shipping will kill sales. Then we have Amazon and Walmart with free shipping.?? People do not a name brand from a way off brand aka rubber stamp name. 10 years ago it was easy to sell Dave? |

Re: Selling Price of Used Minilathe?
Chris Albertson 9:56am? ? One problem is shipping. Companies like Amazon or Grizzly can ship at a much lower cost them you can because of their volume. The buyer, if he is smart, will look at the total delivered cost. You will also do better including only the very minimum of tooling as buyers who are shopping for used equipment are looking for a low cost of entry. Sell the non-essential tooling separately and you might even get more for it.? ? eBay gives you literally a global market and a higher selling price but you have to give them 10%. Selling locally on Craigslist is free and there is no shipping issue but your market is very small. Try that first. It will work if you live in a city where there might be a few million people in easy drive distance. You would think selling locally would be best. But I have sold some 1000+ pound machines on eBay where they had to be shipped on a forklift pallet via freight. The buyer paid about $600 in shipping I agree? Shipping kill a lot my sales. I even will drop price for shipping.? Local is better? |

Re: Selling Price of Used Minilathe?
OldToolmaker Jan 11? ? What would be good asking price for a well maintained ten year old 7x16 minilathe tooled up with all the standard chucks and tooling? Lathe looks great. I was thinking maybe 50% of new? Coments Welcome Is 50 % when purchasing or today's? I think what price would be more helpful? Dave |

Re: Selling Price of Used Minilathe?
Craig Hopewell 5:16am? ? Edited 5:19am If you mean 50% of the new lathe price, and 50% of each piece of tooling (and modifications), that's about right. But you will find the buyers want to pay 50% of the new lathe price, and throw in all the tooling for free. JME I take off most good tooling like. 1) Aloris tool 2) Tapper attachment? 3) Steady rest 4) large ball bearing cross feed screw? Just did this in November? Now the Aloris tool post is on mini lathe. The rest I will slowly sell in time can be over $1,000. All must as I sold the lathe.? Dave? |

Re: Grizzly is doing better - I hope!!!
I'll have to try that.? I've wanted one of those 20 ton presses, but every time it's on sale, it's out of stock in my local store...

Re: Insert tooling info
mike allen Jan 9? ? ? ? ? ? What I really liked is how he explained why the HSS tool cut better . A lot of folks can't get past the fact that with these super small & sharp inserts with the tiny tip , yer really just threading @ 200 TPI when yer chasing a finish with them though that wasn't the planThe give better finish if you flatten the tip of cutter with a diamond file.? I did a lot of turning on turret lathes 0.050 or 20tpi. It gave great finish.?? Thd file I found at Payless drug store for I think $4.99 on sale. Great file too. Dave? |
