    Ok, 50 bucks isn't bad. I think I'll start by ordering a chunk of 52100 just to see if I can turn it. If it goes well, I'll go from there.

    As for the grinding, here's my thought, one thing I...

    The problem with those needle bearing clutches is they don't have the same torque capability nor are they as reliable as the sprag. Some helicopter manufacturers use them, but generally in smaller...

    Designing a sprag clutch assembly

    This is for a large rc helicopter. The sprag is used on the main drive gear to drive the rotor head and allows the rotor to free wheel for autorotations when the motor is shut down. A common sprag...

    Re: Interrupted turning in aluminum

    Sounds good, I'll give a shot. It works out well for setup order reasons, but an added bonus is the automatic chip breaking which is a nice bonus in aluminum

    Interrupted turning in aluminum

    I'm looking at possible ways of processing an aluminum part in the mill turn and there's one possibility that would work out very conveniently, but would involve interrupted turning. Basically a 1...
  6. Re: Need help brainstorming a solution for this mill turn spindle

    heres a few more pics and cad views. 2 cross sections of dual action brake and the whole spindle with closer and brake disk out of the way.

  7. Re: Need help brainstorming a solution for this mill turn spindle

    Yeah I'll post some more pics in a minute here. Hard to show the inner workings of the spindle assembly so I'll post a couple cad pics too
  8. Re: Need help brainstorming a solution for this mill turn spindle

    couple revisions later, its working pretty well. built a pneumatic disk brake for locking the spindle during index milling, very rigid now. it was pretty useless for index milling without it. A servo...

    Re: G4 dwell only in seconds

    wow, huge brain fart on my part. I was using code "G4 Pxx" in my macros for timing. Obviously not the right way to do things. Somehow i forgot about the existence of "sleep" which works just fine in...
  10. Any way to force rotary axis to move only CW or CCW?

    I'm trying to combat backlash in my timing belt driven 4th axis indexing. I know i can set it to short rotation so it only considers the final angular position and takes the shortest path, but I want...

    Starting a macro with an input

    I need to have a few physical buttons out on the machine for activating some things like solenoid for collet closer. Obviously I could just put a switch directly on the solenoid power, but I need the...
  13. Re: calculating thread depth (single point lathe threading)

    Ok, looked through some videos and charts. Looks like I need to just forget about that .866 ratio and instead go to a thread chart, subtract specified minor D from major D, divide by 2, that's my...
  14. I thought pitch x .86 was for single thread...

    I thought pitch x .86 was for single thread depth? On my machine, single depth is what I want. Since I'm using mach3 mill for both turning and milling, all my turning moves are output 1 to 1 and...
  15. Hmmm, 1/2 depth, are you sure? Don't think I...

    Hmmm, 1/2 depth, are you sure? Don't think I could be that far off. The other day I did an m10x1.25, using the full depth (1.25x.866) and it was the same amount of play as the m6 I did. Should have...
  16. Re: calculating thread depth (single point lathe threading)

    ok, so it sounds like im doing it right, just expecting a bit too much from calculation alone. Could be some other variables as well, like index pulse triggering and backlash in Z. Any error from one...

    Yep, I realize i need to dial it in, just want to make sure I'm following the right process for setting up the thread insert and setting the proper initial depth in the first place to get as close as...
  18. calculating thread depth (single point lathe threading)

    Im new to threading so i want to make sure im doing this right. This is on a cnc setup using fusion 360 cam, example of an M6x1mm thread. For starters, heres how im dialing in my threading insert, I...

    Ok, not a huge deal. Only scenario is when servo spindle faults and alarms, chuck let's go. I'll consider setting up pneumatic chuck output backwards so it's normally closed and activating output...
  20. Re: mach3 is toggling outputs when loading gcode

    another related question, mach3 also disables all outputs with estop. Not as big of a problem, but would rather outputs stay active with estop. can i do that?
  21. Re: mach3 is toggling outputs when loading gcode

    perfect! thanks
  22. mach3 is toggling outputs when loading gcode

    Getting some strange behavior. I have 4 macros for my mill turn setup that i use within programs. One for activating spindle brake, one for deactivating spindle brake, one for activating collet...

    Yep, true. I guess I'm also thinking about emergencies for second op stuff. I'll try boring one and see how it goes.

    On a side note, I got some 135 split points as you recommended in my other...

    Re: Buying stock for 5c collets

    So I was thinking i would just start buying cold drawn for better tolerance, but what downside would there be to just buying emergency collets and boring to fit the cheaper stock? I can get cheap...
  25. Re: Any masters at editing with notepad++?

    This turned out to be ridiculously simple to do on the post. The mach3 post in fusion which is based on fanuc, already has the feature of locking an axis for indexing. All i had to do was search the...
