I understand that but it takes a lot to bend one.I'm betting there's something else going on.I'd check it out very carefully before I started machining anything.

Not necessarily.  I know some that could bend or break a tank.

If I believe I cannot do something it makes me incapable of doing it. But when I believe that I can, then I acquire the ability to do it , even if I didn't have it at the beginning.

The chuck has a definate up and down movement like OD the backing plate was machined down to far and the chuck mounted off center.  I have yet to put an indicator on it, but you can see swirl marks on the OD of the backing plate like somebody used a flap wheel on it.  The snout looks straight by eye, but like I said, I haven't put an indicator on it yet.  I'll let you know what I find.

It's not a file size problem. O really means no limit. BUT if you resize them to less than 1000X1000 I have found it works better for me.THere have been times when I tried to post large pics and got the same message and resized pics flew right through.AS you can see tho I KNOW NOTHING about this stuff.

We needed a new 3 jaw chuck.  Chuck showed up and then we needed a backing plate and I couldn't find one for the thread size so I made an adapter plate for our old backing plate.  I think the old chuck is going to end up on a weld positioner I am working on.... here is the process.  Came out right on the money by the way. ;)

Riddle for the day.

What do you call an MT2 taper that isn't an MT2?  We originally ordered MT3 stuff cuz I thought the tail stock looked bigger than MT2.  Stuff showed up and wouldn't even fit in the hole, let alone seat.  So we measured the hole and it was .70 at the big end.  According to what I found on the internet, that matches up with MT2.  So we ordered MT2 Stuff and it showed up yesterday.  I haven't seen it yet, but from what my buddy said on the phone the MT2 stuff is sloppy and won't seat.  Now where do I go from here?

I'm thinking about taking the tailstock apart and maybe getting it reamed to MT3 so we can use common stuff.

Thats what I would suggest if you have the material. It could just be a wore out MT2. Maybe you can ream it MT2 a little deeper to clean up. Any chips or dings in the tailstock will cause problems but you probably allready know that.

yes they are pricey.  I have looked.  I think there is a guy locally that refurbishes equipment.  I know he does shears anyways.  I'm thinking tuesday would be a good time to drop in and see if he has reamers to do the job.  I'd bet I could pay to get it done and be cheaper than buying the reamer and doing it myself.
