omegaghost,
I have a mill/drill very much like yours and my best advice is to:
PREPLAN
By this I mean that you have to figure out how to do the job without moving the head. In my case, I use a couple of procedures to meet this goal (and it has worked about 99% of the time)
1. Raise the work surface so I can have a clear area to be able to have enough clearance at some point on the table to make the tool changes. I do this by either mounting the work piece in my vice or on a "raised table" that I bolt to the normal table.
2. For the smaller (shorter) tools, I use an ER 25 Collet extender and collets to hold the tool. The one I have fits in a 7/8" collet and for the really small tools (like my 1/16" end mill), I can then "slide" the adapter out of the R8 to some extent and be able to reach the work piece (OK, I know this isn't desired, but it works)
Many times in my setup, I will acutally put the longest and shortest tool in the quill to be sure I can achieve the desired depth and/or clearances.
Just my nickles worth
