few questions

[bluedxj]

ive decided to start just one thread and add all the question im gona have as i dive into my new lathe. its a 101 model 12"x36".
first question is how do i remove the chuck? i dont have a dial indicator yet but when i cut something i can tell its got runout.
second what is this knob? im pretty sure its broken because the ones ive seen on ebay have a gear attached. but you can just freely pull it out of the bed.

i got a box full of tooling and was wonder what this is?

and last is there any kind of free owners manual i can download online? i mostly wana know how to lube everything. thanks.

I have no idea what the first item is but the secon is a drive dog. It clamps on the workpiece with the bent part pointed toward the headstock. It's uded when turning between centers to drive the workpiece from a dog plate or faceplate.

Chuck

1) The chuck is screwed on the spindle. It's a right hand thread. Do have steel back gears or zamak? ( makes a difference on the method to remove the chuck)

2) Looks like a feed knob. It the gear still in the carriage?

3) Driving dog. Used to hold round items between centers and the ear of the dog fit in a slot on the face plate.

The top picture looks like the knob to engage the cross feed.

The other is a dog that clamps your bar stock when turning between centers. It's used with a drive or face plate.

im not sure if the gears are steel or zamak how do i tell?
also not sure if the gear is in the carrage dont really know what to look for. ill go investigate. so that knob should provide power to the cross feed?

Can you take a picture of the gears? If they look cast, they're probably zamak. If they're solid, most likely steel.

How the cross feed works....The lead screws turns and drives a gear in the carriage. ( the gear has a single spline/key that is driven by the slot in the lead screw). When you pull that knob, it locks out the carriage feed and drives the cross feed.

Here's some pictures of my friend Dave's 12" Atlas showing the underside with the gear and a a parts diagram.

I haven't taken a carriage off yet. Dave's crossfeed gear is stripped and we haven't disassembled it yet. I stuck my camera under the carriage for the picture. You can hold a mirror and light under it to see up there too.
