Grizzly 4003G Question

I'm looking at this model (replacing three lathes with one) but one piece of information I have not been able to find is if the cross and compound feed dials are direct reading? On a direct reading dial if you dial in .100" that is what is taken off the diameter. Most small lathes seem to have indirect dials where you have to dial in half of what you want off the diameter. I've really grown to like this feature on my 14" Rockwell and my 6" and 12" Craftsman doesn't have it.

Also, is there any indication of longitudinal travel? Some lathes will have a dial on the feed wheel, usually coarse, but servicable.

They are direct read on the compound and cross slide, and also have longitudinal travel dial at .010 increments.

Good Luck,
Med.
 
Thank you Med. You would think that they would add that to the features list on the website.

I am sure the cross slide is direct and I think the compound is indirect but I could be wrong.
 
They are both the same. they move the TOOL .001 per graduation.
 
Well, I recieved an email this morning from a member who said that if the cross slide is moved .001 on the dial, it will take off .001 per side or .002 on the diameter. To me this is not what I consider direct reading and conflicts with what Med has said. Could they have changed the dials on newer production? I haven't contacted Grizzly but may have to in order to find out what is shipping now.
 
I'm not sure if they changed, but my cross slide is in .002 increments, and my compound is in .001 increments direct read. I have verified several times, I guess they may have changed. I've had mine for just under a year if that means anything.

Good luck,
Med.

I should have wrote -

"ON MY 4003g I am sure that the cross slide is direct and the compound in indirect."

I even verified it with a dial indicator before boring out a couple of tuners today.

I agree with crb...

I had to check mine as well! It's a two year old 4003G. The cross feed is direct and the compound is indirect. The cross feed takes a half a thou cut when you turn it 1 thou and the compound takes a 1 thou cut when you turn it 1 thou. This seems confusing but when you take a 1 thou cut with the cross feed the turned piece measures .001" less in diameter, and when you take a 1 thou cut with the compound (set perpendicular) the work piece will measure .002" less in diameter. (checked with a digital dial indicator)

That's the way it should be. With the cross feed, when you move it .010" on the dial's scale, it should take .010" off the diameter. The compound should move the same amount that the dial says it does. This makes it a lot easier to do just about anything when it comes to using a lathe.

For instance, when you need to take .025" off the diameter of a barrel shank, you dial in the cross feed .025" from where you zeroed the cross feed and it should reduce the diameter of your tenon .025". Or if you're cutting a Remington counterbore with a boring bar, you turn your compound to where it's parallel to the lathe bed and go in the depth that you read directly off the compound's scale. If you go in .150" on the compound's scale, the depth of cut should be .150". A quality lathe will be able to do this. Lower grade lathes won't. When threading, on a quality lathe you should be able to hit any numbered or half line on the thread dial for any even pitch thread.
