G4003G carriage stop

[Todd Adams]

I'm a newbie and haven't recieved my lathe yet. I have been spending alot of money on tools and what not for this lathe. What do you recommend for a carriage stop indicator.

One of these works for me.

Thanks. Do I need a gauge with the post on the back? What do you have.

 

[Todd Adams]

Never mind, l just ordered on ebay, and it comes with the indicator!

I have one of those mag holders, I drilled and tapped a hole in the side of it to mount a 1" travel indicator, it works well.

I like the round type & the blue ones are cheap, less than $10.

That is exactly how I do it.

But it brings up a point. I am thinking about making a carriage stop that connects into the motor (FW,off,ReV) bar so when the carriage gets to the stop the motor is turned off. A simple mechanical translation of carriage movement into rotation on the motor bar.

You can do that with a RIB relay and 24vac xformer.

How do you deal with the coasting of the lathe after electrical shutoff? The distance the carriage coasts changes with spindle speed, tool load and feed rate. When I need to go right up to a shoulder I kill the power in plenty of time then turn the chuck by hand the rest of the way.

Still in the concept stages.
