Easy fix for you Ed Its your preload. Remove the cap where your draw bar goes on the top of the headstock. You will notice a round black finish "nut" that ...

OK Well here we go. You need to get the spindle loose. I would get a 2x4 and place it over the spindle, (lower the headstock all the way down for this !) and...

WAIT!! Don't try to hammer the spindle out with the head on the mill. You will just bust stuff up! It ain't that simple. Now, giving the top of the spindle a...

A couple of good raps won't do any harm. Especially if you lower the head all the way down to reduce bending modes to the column. The head takes more abuse...

Easy enough. I guess it is really relative to how many machinery have you delt with in the past. When you sat the spindle was tight in the bearings do you mean...

Thanks Phil, Yes the ends are not flush. Two meet up very accurately but the third site about .010-.015" higher. The runout is so bad that you can easily see...
i have been very impressed with the grizzly mini mill, it seems to have no problem taking a cut 1/2" wide and 1/4" deep in 6061.... with a half-inch hss...
I guess it depends on if you are comfortable with that cut. You can always try a deeper cut, but watch for chatter and tool flex. Also keep in mind that the...
Perhaps you have already tried this, but, I have lately been using my small shop vac when I am milling to suck up chips while I mill. I have found that not...
How many parts are you making? This is not a production machine in any way. Will you save large quantities of hours by taking huge cuts to make one piece? ...
Well, it's only been two days, but I'm pretty happy so far. Rick (owner, REX Industries) says that he doubts he will put any more of these USA made R8 spindles...
I am considering purchase of a HF minimill to use as a precision drillpress. I wonder if anyone (more than one) member has checked for runout at the end of...
Runout on my Grizzly Spindle is almost non-existant. The week link is the MT3 Drill Chuck that comes with it. The runnout on that is considerable. The HF is an...
