Thanks for ALL the tips. Without taking apart a drill, how do you check for tight bearings?Leave a comment:

Only the cross feed screw had any appreciable wear, as the machine was primarily used for facing operations. A machine like this will last for generations in a home workshop.Leave a comment:

$69? Paid about that for this one. Almost thirty years ago mind.

The spindle the chuck is attached to; or, if you will, the shaft that leads from the motor/belt pulley down to the chuck. The spindle/shaft Is usually supported by one or two roller/ball bearings (or a big Oilite in cheaper units). If, over time, and/or hard use, ware increases the non-interference fit between bearing and spindle/shaft, it will cause the work to vibrate laterally to the tool pressed against the work. Setting up -- under the right conditions of load, feed-speed, tool pressure and angle, and RPM -- a resonate vibration that will evidence on the work as 'wavy' lines. Chattering. Change any one of the variables and you alter the amount of vibration. Tight bearings mitigate all this happy horse-****.
Loose bearings breed vibrations. Duh!
Don't make me come over there!

Dremel AC speed controller. A generic version is also sold by Harbor Freight. And buy the foot-switch -- makes life easier.

Get it Be Dam Careful BUT can be done. I see, said the blind man to his deaf wife.
Your drill being used, the chuck 3/8" or 1/2" ? Is one better than the other, why?
My mind has a brain cramp, the device that controls the power/speed is called?

Slow speed, very soft metal (white-metal, machine brass, etc.), sharp tool, tool rest right up against the work. Band-aids at the ready! When work is completed, inventory fingers. OSHA can kiss my fat, pimple-encrusted, diabetic ass!

WOW!!! I have to ask though, for non metal turning it looks Good BUT to work with metal, I don`t see how you can safely work with cutting bits in your hands???????????
