The last few times, putting my 10" 4 jaw chuck on my L00 spindle equipped lathe has been a
struggle. I have a couple 3/4" pine boards I lay across the bed to help support the chuck
while I turn the spindle nut.

Lately this hasn't been working. A 20 minute chuck change blows backwards. I couldn't
get the nut to engage.

I felt rather dee de dee today when I figured out what had changed on me.

Normally, having a fairly logical mind, I've indexed the drive key up when putting the
chuck on. Lately, I've been turning stock with a diameter such that my jaws extend past
the chuck body. That made it impossible to put the chuck on with the key up.

Today after a bit of frustration, I re-thought things, retracted the jaws, indexed the
spindle with drive key up and it was easy peasey to align and tighten the nut.

Sometimes the obvious is oblivious.

Those big chucks give quite a workout when changing them. I did same
today (12" drive plate and a 6" chuck).

When it gets warmer and I feel like working in the unheated portion of my garage, er shop,
I'm going to fire up the bandsaw and cut a couple custom cradles to hold my two chucks in
perfect alignment with my spindle.

Just get an old morse taper drill and clamp it in the chuck, then
insert it in the tail stock. The same process works when removing a chuck

Wes sez: "Sometimes the obvious is oblivious."

As an old military instructor told me, "If you can find an obvious problem and fix it, the unobvious
problems are usually fixed in the process".

I probably have spare MT stuff. Let me know what size you need.
