I wonder if Carlton offers a "sensitive drill feed" as an accessory?

I wonder if Carlton offers a "sensitive drill feed" as an accessory?

No, as insensitive any machine can be. Will eat any thing that tangles with it, so has no gender sensitivity either.
But an elevating table [actual sensitive drill] would be some kind of project!

If cabinet next to the Vidmar is 36", the arm is ~11' 4'', indicates some miscalculation. 10' or 12' would be realistic. Figured column at 25'', also not common, 30'' though.......Spindle could be 5, 6 or 7 Morse taper. By interpolating current geographical position, azimuth and birth sign; actual dimensions turn out 10' arm x 26'' column.

I was relieved further intense math by enlarging the pic; typical all radial arm drill presses, size is stated directly on the machine. But hardly equal fun-factor.

Machines this size often use quick change (QCT) tooling, like this one appears to have in place. Changing bits other wise might detain a helper catching the bit or wielding hammer and drift. QCT can save lowering and raising the arm as well.
Majority of radial drills have a self contained base, with many as 3 perpendicular tables, known as "L" or "T" bases. This one is mounted on floor plates, giant slotted castings to clamp down work. Likely 6MT, and 30hp, it'll run a 4" drill in steel.
We all know one guy here, who's wife really enjoys running radial drills..........and she is tiny!
