    Very neat installation!

    One comment only if I may. Not sure looking at the photos but I think your X head protrudes a bit from the vertical table's face plane. This might be an issue when mounting...

    There you go! Machine tools to fix machine tools :) Nice progress on fixing your machine by yourself, though I was dying to see what Ross would build for you....

    Hey guys,

    Opened both my X belows and checked these M6 stops. They seem to be stops for the manual operation, the extra travel that is only available manually after the feed has tripped. This...
  4. Your shear pins are correct for sure, but can you...

    Your shear pins are correct for sure, but can you say the same for the one that was on the machine? Be it loose gib, crash or whatever, the shear pin should break first.

    If the original shear pin...
  5. Hey there, what you are saying makes sense,...

    Hey there,

    what you are saying makes sense, but I still have some grey points:

    - the machine should work even without the door-side cover altogether! Thrust bearings on the operator side would...

    These collets seem to like that....I have had it happen three times since my first euromill, everytime with these 355E (U2) collets.
    I remember each of these times....(in my cases, due to the...

    Right Bill, I guess phenolic would work just fine. I did have a piece lying around but it was much larger in diameter and I didn't feel like wasting it. So, I guess it will just keep on sitting in...

    Hey there Bill,

    yea, glad it did work out!
    Tonight I checked again after hooking everything up on the actual machine. Everything works perfectly! And, as one would expect....second variac works...

    Well, something like that....

    I will have to check. I think the chassis is grounded with a separate wire to the mains, or, at least, that's what I hope is the case.

    Let's see how this all will...

    Hi there guys,

    I have some progress to report, though there are still some 'grey' points...

    Yes, yes...what can I say... Always not 100% certain about my English, especially tool slang, so I thought... haha...



    Yeap, as I said, got my incandescent lamp already at hand for my debug...

    It's 90mA DC going to the armature. Didn't check for AC, will do. Also, checked one wire only. Are you thinking about a leakage in the motor when suggesting measuring current at both wires?

    Yes,...

    :D:D:D

    Haha, still laughing.... no...no goat at hand, let's stick to sustained thinking!

    Right about current going somewhere, let's narrow it down.

    90 mA that I measured going into the...
  17. Hi there Bill, - Variac with no load is ok....

    Hi there Bill,

    - Variac with no load is ok. Field connected, Variac connected, diode board connected, only armature disconnected. No heat, no noise, nothing. So, this could mean that I haven't...
  18. Hey there Bill, it seems I will have to fire...

    Hey there Bill,

    it seems I will have to fire you, you're getting too expensive for me :):)

    Indeed, it's the Variac that seems to be not in order, that's why I got a second one (off another...
  19. guys help....

    So, latest report, not much in terms of progress, hope someone can help:

    I went on and rebuilt the diode board, replaced everything apart from the 220Ohm/10kOhm resistors (didn't find them in that...

    Hi guys,

    well, I found some time to check the diode board today. Of course is measures perfectly....
    Only the filter capacitor measures at 160 nF instead of the nominal 100 nF, but I was just...
  21. Hey there John, So this answers what happened...

    Hey there John,

    So this answers what happened to the door-side cover...(somebody had asked that before). That poor taper pin is not a shear pin, not so easy to break...it took quite some force I...

    Right,

    thanks for the 10k explanation, makes sense.

    Regarding the field supply, why did they choose to alter it in some models? Be it rheostat or high/low taps. What do you loose if you keep...

    Hi to all,

    thanks for the info, it's been quite some time since I last had anything to do with motors (this is no excuse though, I should know some of these stuff...).

    First, thanks for rushing to correct the diagram and help others in the future!

    And, only because you mentioned it, your diode-bridge part in the schematic is not correct. Not that it actually...
