$48 spindle?

Thoughts on this?

http://www.oldfoundry.com/catalog/produ ... ucts_id=79

all ball-bearing construction
stong torque motor rated at 1/3 horsepower
0 RPM to 15,000 RPM variable speed range
includes extra brushes for motor
can be used on CNC (computer numerical control) machines and on manually controlled machines
5/32" capacity on a jacobs chuck
machined spindle is one inch in diameter
three-prong plug on motor
flexishaft length is 32 inches
all metal construction and insulated electrics
plug wire on motor is nearly 55" in length
motor can is 3-3/8" in diameter
motor can is 5-1/4" in length, a little over 6" overall length
motor and spindle are tested in our shop before shipment


In particular, I’d always thought Jacobs chucks were suited for drills, but not for side-loads.

The description says "flex shaft" also, and I'm not a fan of that.

I'd like to see a picture. But I wouldn't want to use a Jacobs chuck for milling.

I'd like to be able to drill and tap in steel and thick aluminum so that shouldn't be much side load.

Some of the robot guys use drill motors to power their robots and have adapters to mount on the 'bot. The high end ones use DeWalt drill motors but I bought a Harbor Freight sale 3/8" 0-900 rpm variable speed drill with an LED flashlight that uses the same 18V battery for $22. There are instructions available for removing the Jacobs chuck and getting to the threaded shaft. I thought if the shaft had the right thread, I might be able to change the Jacobs chuck to a collet system although I expect the run-out on that priced device to be fairly bad. If so, I've got a $22 flashlight.
