  1. Of course, that is what you do. Just for illustration I wrote it like that. I've been using these controller for many years and not had any problem with them.
  2. Before I can recommend you using one of these methods I got to see the setup, motors and the connection box on the actual machine. If there are two three Ph motors on it, one clutch motor and a regular AC motor (one speed). Then both these methods will work fine. But if one of the motors are a DC servo motor or the machine has an electronic inbuilt speed control, then it's a difficult task. It still might be possible, but a much more difficult project.
  3. Depended of how much amp and watt the motor is on, you got to buy a little bit over size. You can get them used on Ebay. I would guess it's possible to get one new (the right size) for the machine between 50 to 70 USD. However, it's easy to rewire a three Ph AC motor to single too. All you need a capacitor to mirror one of the Phases, See pic. The bigger the capacitor is, the less torque you loose. Because, the AC motor is always stronger when it runs on three ph, than on single. Here I've have used two big capacitors instead of one. But they are connected the same way as with one. It's an 1 KW AC motor for a air compressor. The frequency controller is the best option when you need the possibility to adjust the speed of the motor. I used them on everything from sewing machine clutch motors to the skiving unit. I always have some laying around. Gigi uses one on their skiving machine too. I always use the easiest method when I need to connect a three Ph motor to a single Ph net. On the skiving unit I would have to rewire two motors with capasitors. Therfore I just plugged it in to a frequency controller, much easier. You also have to connect a little switch, for the startup of the machine. I only used a little lamp switch ( I used a foot button lamp switch with two wires/poles). Of course you have to read the Pdf instructions/manual for the controller. The Watt and amp rating on the motor desides how big it has to be. This is one on 0,75 KW. The single current from wall outlet comes in on the top, the white cable goes to the start switch (lamp switch). And the four other goes to the motor conections(or machine input box). To connect the four (output) wires for the motor: Earth on earth of course, then you just going to try with the three others. There are three contacts on the motor where they should be conected. If it doesn't start, change them around and if it starts and goes the wrong direction; change them around again until it starts and goes the right direction. There is no other way to connect these, try and fail (it's not dangerous). With this type of controller you can control every parameter on a AC motor if needed, like tourque, speed, startup time/stoping time you name it. But in this case you do not have to do anything else than set the hertz to full (full speed) This is easy to do if you know the principals, if not get some help from an electrician. Tor
  4. Mine has three motors, one 380V for the knife that runs on full speed. One for the suction device, also 380 V on full speed. And a little 12v DC motor inside the head for the feed wheel. I do not have three phase (380V) in my workshop, so I just connected a frequency controller. It's plugged in my 220V single Ph outlet and four leads goes from it to the 380V inlet on the machine. The controller converts single 220v in to three phase 380V. And the hertz controller on it gives the full 50 hertz all the time, motors run at full speed as they must on this set up. That's how easy it is to do this, ask Gigi for help. By the way all AC motors are initially a three phase motor. Tor
  5. Disregard my question, found them here in Oslo. Thanks anyway
  6. Hi, I use an Italian edge coat with small machine /hand applicator. However, sometimes I need to use the old method with Fibings or simmilar. I always wanted one or several of these empty markes, but can't find them for sale where I live (Norway). Could you please send me a link to where to buy them. Thank you, Tor
  7. Wow Bob, from Weaver leather? what kind of machines did you buy. I hope you got better prices than on their web site. Nearly 5K $ for a Adler 205-370 clone (with 16 "arm). "But as close to an original Adler as we come" still is not a Duerkopp Adler machine. You know the story behind these, Thanks, Tor
  8. Really nice work Mechanic, exited to hear what stitch lenght you will get when its done. Tor
  9. Either way a skiving machine makes noice regardless how many motors they have, the grinding is very noisy. If you can get an Italian machine with constant speed and vacuum for the same money as an basic Chinese machine, your choice would be easy. Do not even dwell about it, just grab it. These machines have a pretty step learning curve and the Italian one would be much easier to use. Tor
  10. They use thinned white glue, it's water based. And can be mixed with colors etc.
  11. Can't see anything great with this tool that defend a price of 430 Euros. You can almost buy a small Italian powered edge paint machine for that price
  12. I give you a "like" on that.
  13. I would choose that Italian machine, the Italians make very good skiving machines. And I agree with Brian, a exhaust/suction system is important. Of course a constant speed bell knife machine does a much better job and are easier to use. I have an Italian Alpha machine with three motor setup, little servo for the feed wheel, one for the knife and one for the vacuum system. Very happy with it. Tor
  14. Hi Constabulary, Yes of course they where South Vietnamese, that was what I meant to say. Captured by the North Vietnamese and the Russians, I guess the GDR has "good" prisons About a year or so before the wall fell, I was sent to Verningerode at Veb Electromotorwerke to load motors. (Norway used them in our trains and trams) We alway had to have a customs officer present when loading/unloading to open the sealed trailer. We had to come at, say 0700 hour sharp to load, if one minute past you had to wait until next day and then the visa (Kraftfahrer visa I think they called it) had expired. They you would be arrested and accused to be a spy but they let us go after some hours and lots of interviews and paper work. We only got 24 hour visas so if something happened, and it aways does. So I was accused as a spy several times. Back on track. I came that morning to load there was no more electro motors, I asked the customs/police officer why. He told me that all the Vietnamese POW had been issued amnesty and released. And something had changed, there was lots of aisian people selling stuff in the streets and colors everywhere. It came as a shock to me that these POW had hand wired all these big motors, nobody knew. I do not think Norway would allowed the buy of these train parts if they knew, I don't thick they still know anything about it. That city, Verningerode was about untouched by the 2WW and had old beutiful wooden buildings. Have not been there since that time, it was very different from the other gray east German cities. I was also many times in Leipzig and that factory building is just what I remember it looked like, but no clear skies; just fog of coal all over. (never as clear as on your pic) Tor
  15. Hi and thanks, you all did a great job on this machine. Gray is a good color for it Constabulary, and gray is the color that hit you when you passed the border in to the old DDR. I worked as a truck driver in the 1980´ties and drove a lot on DDR, loaded electro motors from Veb Electromotorwerke (who was made by North Vietnamese prisoners of war in DDR captivity, I did not know at that time) and clothes for Norwegian fashion stores. I visited many factories and was always invited to "dinner" ,a spoon of mashed potatoes, a piece of meat size of a dime and some brown salat. The table fork and knife was made of a soft metal that bended on the meat. The workers did not have food but made machinery of the best quality and steel. They always wanted to prove they where Germans, and did so by putting there pride in making good products. I never forget the fog of coal and smell of two stroke gasolin, the tough, long border controls when they accused me of being a spy Anyway, my point was that they made the world best electro motors and most of the other (industrial) stuff they made was top notch even without food.
