Adam Savage Fixes His Lathe Live Center!
Рет қаралды 99,422
Жыл бұрынAdam gives a breakdown of how his lathe's tailstock and live centers work, and shows how one of his live centers is just 1/8 of an inch too short to marry with the taper inside the tailstock. So today's repair job is to extend the end plug of that live center by machining a replica of it--using the lathe itself!

If your threads lock up after a few turns they are usually not cut deep enough. Just give them a little more depth and a couple of spring passes. Also make sure you tool got the correct flank angle. There are inch treads with 55° and 60° angle.

I'm trying my best not to be mean because Adam is a great guy and just genuinely enjoy playing with his toys, but those threads don't even remotely close, so the only useful tip would be to try to identify and cut the correct thread. I doubt this part would last a week in a high production environment (especially if that bearing does indeed ride on this, in which case this should be hardened), but in a prototyping shop, this will easily outlast it's maker (so troubleshooting is kinda pointless)

Nice video and a good job. Just a little note. When single-point thread cutting. Do not disengage your half-nuts on Metric threads. Get to the end of the cut. Back the tool out and then run the lathe in reverse about an inch or two pass the end of the work. Move your compound or cross side ( depending on your cutting method) to the next cutting depth and run the machine forward to cut that pass. Repeat until you get to the depth. Standard threads you Can disengage the half-nuts.

Hi Adam, I love your channel and the work you do in your shop and everything you share. Thanks. I want to add a safety note: Please do not wear your watch when using machine tools! No watches, bracelets or rings is pretty much number one safety rule for machine shop work, right after eye protection. And no necklaces or long hair (or hair kept well constrained) is next. Be safe and keep on making!
@PhilG999 Жыл бұрын
Absolutely! I spent most of my professional career as a Mechanical Engineer (now retired) going into machining environments where everything could cut you, squish you, or burn you. Went to a vendor's place years ago to see about a machine part they were making for us. Walking toward the shop area I took off my watch and Southern Polytechnic Alumni Signet ring and dropped them in my left pants pocket. Started to walk forward and the guy said: "You need safety glasses"! I said: "These are NIOSH, MSHA, OSHA rated polycarbonate (I have all my eyeglasses made that way)." He said: "They don't have side shields". OK, I took one of their pairs off the rack and put them on OVER my glasses". Took one more step and he said: "You need to take that tie off"! I reached up and grabbed it and handed it to him (it was a clip-on). "Anything else"? 😆

I'm sure you know, but another fyi to new lathe operators. Not only is the one lever for cutting threads because it feeds slower, but it also is typically gear driven, while the other is clutch driven. The clutch is an added safety measure if the lathe is crashed, but is usually not precise enough to cut threads.

Make it easy on yourself. We simply stick a magnet of the proper thickness on the back of it. They when it needs to be ejected the magnet is in there for the spacer. Haven't crushed one yet. But I must say we don't gronk down on inserting the tool into the taper. Just enough to make it hold. My fear is that too much might crush the magnet. This idea came out of an emergency situation where there was no time to do anything else. As usual the center is still that way. Thank you for the video!

I would have been tempted for reasons of "sexy" to put a bit of a knurl on that part. Beautifully done. Me and my buddies took a machine shop "night class" for 7 years (mostly for cheap access to a not bad machine shop). I still learn things watching Adam, and "Inheritance Machining" and "This Old Tony". Again, Adam, lovely part. The very first part I ever made in a lathe was a bronze bushing for the power-head on our pricey vacuum cleaner. I was SO proud of that little part. That was probably 20 years ago, and as far as I know, it's still going today (she got the vacuum cleaner in the divorce...).

while you may have had the correct pitch, what thread angle were you using 55 deg or 60 deg, the metric thread should be 60 deg, if you used a 55 deg cutter then it would bind. after a few threads.
@simonilett998 Жыл бұрын
UNC, UNF and Metric all use a 60° thread form. However, Whitworth threads use 55°, but I highly doubt Adam would ever need a 55° threading tool in the US🤣 The thing that caught my attention was him starting off with such an odd thread pitch (26tpi) made no sense. I'm pretty sure the problem he encountered was his orginal major diameter was too large to match the metric size he realized it needed to be, due to him starting with an imperial major diameter. If he'd reduced the diameter 0.1-0.2mm less than the correct metric major diameter for the finished thread, and then cut the 1.0mm pitch thread to the correct finished depth, it would've been a win👍
@1pcfred Жыл бұрын
