Popular Post Adoom Posted October 31, 2019 Popular Post Share Posted October 31, 2019 So I got this. It was so close to home, only 3.6km, I just had to click buy now. I got the local towie with his HIAB to pick it up and move it. It took ~1.5 hours. $120. We had to do a bit of manual handling because the truck could not get close enough and the crane boom was too high to fit in the garage door. At the pickup, the old fulla used/abused his engine crane to get it to the door. Then used the hiab to drag it over some bits of ply so it was close enough to lift. At my place, ideally he needed to park across my garage door.... but the driveway doesn't really let you do that. So we ended up with this compromise. My garage door is 3m, but the crane only barely could get under it. We got the headstock in, and placed it on some 25mm round bar. Then picked up the tailstock end and got it just in the door. Once it was in, I found it was pretty easy to roll on the bars. I took some size comparison photos to compare with the myford. And "What's behind the SCARY DOOR"? Buuuuuhhhh... Obviously it's 3 phase. It came with a motor, that was not installed, because he was going to install a different one. I'm going to see how I go with a 2.2HP single phase motor. I'll just wire it independently... But back to the scary door. It was sealed closed with some old as silicone. The black cable is the 3 phase feed. The white cable goes to two limit switches on two of the feed screws. The cabling to the motor comes out from behind this lot. The thing in the middle appears to be newer than everything else. As far as I can tell, it's an anti tamper breaker/switch, I believe the door presses down on the white bit when it's closed. That box to the right.... no fucking idea. Those three round things on the left... uuuh, fuses maybe?? There are two big rotary switches. Not sure what both do. I assume one makes the motor go. The other could be reverse maybe? They have no names, just 1 and 0. And a transformer. But why?? I've found fuck all documentation. I'm not even sure what the model is. They don't seem to have model numbers on their lathes. I suspect it might be a version of the M0 model. 15 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 31, 2019 Share Posted October 31, 2019 where did you find that ? had an exact same one at my old work which has since shut doors wonder if its the same machine. Quote Link to comment Share on other sites More sharing options...

It was in carterton. Old guy had it for years. I think he said it was ex railways.. or some other gubmint place that has since shut down. There was another one on trademe recently. It looked exactly the same model. Same year even. It was in Hamilton. This one. https://www.trademe.co.nz/Browse/Listing.aspx?id=2362340323&archive=1 Is that the one you are talking about?

Muncie Posted October 31, 2019 Share Posted October 31, 2019 Nah the one i used was same colour as yours had been retrofitted for modern cutting tools etc. probably went up for sale about 6 years ago. I learnt on my granddads myford from around 5 years old. Lathe is on my bucket list. 3 Quote Link to comment Share on other sites More sharing options...

Adoom Posted November 1, 2019 Author Share Posted November 1, 2019 Ah! I think the transformer is so you can have a 230 volt work lamp! 3 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted November 1, 2019 Share Posted November 1, 2019 Very nice, super jelly. It'd be worth a re-wire and revamp if the slides are still good, maybe a VSD would be nice with the 2.2hp motor (soft start etc) Awesome! Quote Link to comment Share on other sites More sharing options...

Adoom Posted November 2, 2019 Author Share Posted November 2, 2019 So the threaded collar that pulls the chuck mounting flange onto the spindle taper was stuck. The guy I bought it off said the previous owner also could not get it off and broke the big c-spanner trying to undo it. So this thing has been stuck for YEARS. I reckon some gorilla had been trying to "undo" it with a big fucking hammer..... the wrong way, so they were tightening it. Enter....ME. Right! big fuck off levers must solve this! So I tigged a 12mm bolt onto the c-spanner to fix it. Then made this no-turning-for-you thing. And put a long big of bar on the spanner handle. And discovered that my 82kg is insufficient weight to hang off the lever. So I swapped to the other side so I was lifting the lever up..... and proceeded to start tilting the lathe over.... Hmmmm Then I tried putting the trolley jack under the lever so the lathe was just starting to tilt, and whacking the collar with a hammer....Nope. So then I tried wedging a big bit of timber between the bed and the drip tray to give me a place to put a scissor jack. And jacked up on the end of the spanner. There was creaking from the jack and cracking from the wood. I got a whole lot of pressure happening and I was just waiting for it to explode in my face. I gave the collar a smack with the hammer and BANG! it fucking turned. HAH! It still didn't want to push the mounting flange off the spindle taper. So I started hammering on the back of the bit of angle. SUCCESS! The taper came loose and I could push it off by winding the collar by hand. It was a bit grubby in there. Here it is after I gave it a scrubbing with WD40 and a scourer pad. So the 2.2hp motor I want to try put on it has a 24mm shaft. The dual belt pulley that needs to go on it is for a 28mm shaft. I will try make a sleeve to make it fit. I'll also have to find a taller key. 8 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted November 2, 2019 Share Posted November 2, 2019 Could just buy a pulley with only pilot hole drilled? Might be good to choose one with smaller pulley ? Quote Link to comment Share on other sites More sharing options...

So just I've ordered that. ~$40 3 Quote Link to comment Share on other sites More sharing options...
Popular Post Adoom Posted November 3, 2019 Author Popular Post Share Posted November 3, 2019 Electrolysis for the win. Ans a scourer pad... and soapy water. Came up well. I oiled the 4 jaw so it doesn't rust again. 14 Quote Link to comment Share on other sites More sharing options...
Adoom Posted November 4, 2019 Author Share Posted November 4, 2019 Cleaned up the big faceplate. I need to find a home for these things (close the the lathe because they are heavy). 8 Quote Link to comment Share on other sites More sharing options...
Adoom Posted November 7, 2019 Author Share Posted November 7, 2019 So I'm trying to find some electrical switch gear. It needs to be able to handle >14Amps. I'm pretty sure it's not a good idea to use the switch on the wall outlet to turn the motor on/off. I haven't got around to actually checking, but I assume this isn't going to have a reverse gear. Reverse would be nice, so I'd like a reverse/off/forward rotary switch. I believe I know how to wire the motor to make it go in reverse. Finding an appropriate rotary switch is not as straightforward as I was expecting. I want to do forward/reverse and an emergency stop button(which could be part of an on/off switch). Does anyone have any suggestions of what to get and where to get it? 1 Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted November 7, 2019 Share Posted November 7, 2019 This guy? I think we have the same switch being used to forward/reverse a 3ph motor. Unsure of what goes on behind the scenes though https://www.pdl.co.nz/Trade/Products/ProductDetail?catNo=PDL56SW320FRLE&cat=3&sc=17&r=1644&nt=1644-509838&nt2=509838-321959 2 Quote Link to comment Share on other sites More sharing options...
datlow Posted November 7, 2019 Share Posted November 7, 2019 3ph = easy change any two of the three phases and it’ll change direction, so can be a switch anywhere along the power lead 1ph= only one phase so you need to change around 1/2? Of the windings in the motor some will have all the windings wires run up in to a distribution block so can be tapped into with a rotary switch some will have them joined together down in the windings so can’t be altered and it’s fixed direction 2 Quote Link to comment Share on other sites More sharing options...

So it's got a box on the top with the start and run capacitors, then a distribution block thing with 6 wires that go into the motor, so I suspect I will be able to reverse it. 1 Quote Link to comment Share on other sites More sharing options...
Nominal Posted November 7, 2019 Share Posted November 7, 2019 J5's link has a technical data sheet that shows some single phase wiring. 1 Quote Link to comment Share on other sites More sharing options...
