Got rotary vice, but......

I got this so I could make my mill brackets, but not enough vertical travel to use it.

Been following this project with interest, David--if you don't mind clarifying, what exactly do you mean by not having enough vertical travel? There's plenty of ways around that depending on what your problem is.
 
The bed is all the way down, spindle all the way up, piece to mill is 4x4 aluminum.

Ideas are welcome.
 
I just noticed the drill chuck is still in there, that cuts about 3" of vertical clearance, I will pull that out and put in 1/4 mill bit, then remeasure, might work then.
 
Thanks--gotcha. They also make stub end mills and various flavors of shorter drill bits, such as screw machine bits, that might help if you're only a bit shy of room once the chuck's out. What is your typical method of holding mills--R8 collets?
 
Same as my little HF mill, then--it's pretty common on the smaller ones regardless of brand, also granting that many of the smaller ones are ONLY different in brand, and the major parts are all the same, from the same factory. Was just thinking if it wasn't and took an end mill holder that that might be another place to gain some room, but that's not going to be the case.
 
The bridgeport type mills use a tall ring
That goes between the base and ram
With longer studs , maybe u could
Make one for your mill
 
Does your head rotate 90 degrees. If so and you have enough table travel then you could flip the rotary on it side and do it horizontally.
 
I made a 5/8" straight to 3/8-24 arbor for my mill. The quarter inch chuck that goes on it is a lot shorter than a 1/2" or a keyless chuck. If the drill is the size of a collet you can put a drill in good condition in the collet and eliminate the chuck.
 
I went out last night to look at this and check drawing updates.

There is plenty of clearance with drill chuck out using collet.

I corrected my drawing the wrong way, good thing I checked, corrected the other way today, will test tonight.
 
Cutting an inch off of the drill bit butt end is also a quick solution. Using a collet allows the bit to be as far recessed as needed. Jim
