Sorry, I wouldn't be able to do it for you myself. But if you go ahead with it, here is what I did to install it true.
The connectors are:
Varitube 510 connector is M10x0.5, hole is 9.5 mm (0.374016").
Fat Daddy 510 connector is M10x1.0. hole is 9 mm (0.354331").
A letter size bit closest to the required hole without going over should be selected.
You will also need a level, and a vise mounted on the table of that drill press.
And a scrap piece of aluminum to make a practice run on.
Use the level to check what the press table reads. It doesn't need to be level, but you need to know that, e.g., front to back is 1/2 bubble high in back, side to side is plumb, what ever the case may be.
Load your scrap in the vice, set the height so that you can chuck (and un-chuck) the bit without disturbing the workpiece. check that the surface of the scrap reads the same as the table. If not, adjust.
Once it's true to the table, drill your hole. Now remove power to the press, remove the bit, and chuck the tap. Lower the ram, and use your hand to start the tap. Once you have the tap well engaged, you can loosen the chuck and finish the job with a hand tap handle.
After tapping the scrap, check that your connector mounts flush and true.
If you are satisfied, use the same principle to work your piece, If it came out goobered, find another piece of scrap. Lather, rinse, repeat.
Hope this helps. If not you, then someone.
