Quill/Spindle Assembly Removal

thanks...very hesitant to start drilling into the machine

the screws are allen cap screws

the issue is not the screws per se...they screw in and screw out

the issue is alignment - i cannot get the hole in the lead screw to line up exactly right - so, as i back out the nut screws, it interferes with the lead screw and gets stuck

LI said not to press that b/c it can strip the threads in the quill (big pita)

i am thinking i need to take the head apart a bit to free up the lead screw at the top?

there are four allen cap screws that hold on the wheel assembly with the worm gear that drives the lead screw

there are 4 allen cap screws on the left side that hold on the auto feed assembly

not sure exactly what to do...
 
Hi Flyrod,

Just throwing out ideas........

1) Can you clean the holes where the heads of the socket head cap screw are? Maybe a better view would help.
Are the heads binding because there is a burr where the nut rides over the holes, if so maybe it can be cleaned up with a file.
Perhaps it is not the heads binding on the holes. Could the ends of the threads on the other side be damaged?

2) It's not clear from the drawings, is it possible that these items:

at the bottom of the screw are used to force it up and remove end-play?
If so then loosening/removing them might give you some slack.

At this point, you have nothing to loose, go easy, don't force anything. It should come off okay. At least it'll open up another avenue to go down on the disassembly.
 
ok...it came off - basically the threads are not long enough on though screws to come all the way out, but they should have entered into the lead screw - to get around that, i took of the 4 bolts on the front of the head assembly and the 4 on the side that attach the auto downfeed (the two assemblies are perpendicular to each other and the end of the wheel shaft terminates in a gear in side the auto feed - here are a few 20170702_151054.jpg 20170702_174636.jpg 20170702_174648.jpg pictures:
 
by the way...is this how the top of the spindle should look?

That is crazy how Index did this! Glad you got it apart!

Thanks for sharing.
 
it is the part of the spindle at the very top, with threads underneath it (haven't used the mill (or any mill) yet)

Only if someone's been beating on it with a big hammer.
Wow, that's fugly!

Sure you can grind off the "flowered" end to clean it up, but can you adjust for the lost length?

That's what's left to the end of the drawbar, not the spindle. Oh boy! The fun has just started.

Look at the assembly drawing you posted above.
