Lathe Carriage Stop

[Hawkeye]

I'm getting to know my 'new' Storebro lathe by making up some accessories that I find useful. A few times, I have been missing the carriage stop that I have on the Hercus lathe. I corrected that deficiency today. This design includes both a hard stop and a dial indicator to give advanced notice that the stop is coming up. With a bit of practice, you can drop out of power feed with about 5 thou left to turn by hand.


I have it adjusted to zero out on the hard stop after 1/2" of contact. I'll replace the hex-head bolt when I can get a 2" SHCS.

Very nice job Hawkeye. This is definitely a tool that you will constantly find yourself using.

Great idea and great tool. It is nice to have a hard stop and an indicator stop also. I use a magnetic base ,but it is a pain in the rear to get it to stay in the right place. I definitely need one of these. Trouble is I'm involved in two other projects right now. Boot

Mr. Hawkeye;

I am not so much worried about the hex-head bolt as I am about the stop rod tap.

Very interesting.

Use mine all the time.

Tap, stop, and DI.

Just not all in one unit!

When I was looking for a piece of rod to make the hard stop, I spotted a broken tap on the bench. I spun the broken part square against the grinder and took the tops off the teeth. I spun the tip at the other end to make a small diameter so it's not as sensitive to swarf as the 1/4" tip on my other lathe.

Someone help me out here.
How does one use a "solid" carriage stop.
I regularly use an indicator in a carriage stop type holder to measure carriage movement which leaves plenty of time/warning to disengage.
It seems to me that poor timing on disengaging with a solid stop would cause a "crash" (carriage into stop) that would damage the feed nut.
Maybe my reflexes arent fast enough for a manual stop at the exact same spot every pass?
Just Askin :thinking:

my question too. does it engage the clutch? That would be my guess but I'm scared to try it because of half-nuts .....not me on the screw

You disengage the auto feed right before you get to the solid stop, then you manually feed into the stop. An example would be when your turning down to a shoulder on your left or right. You can set the stop a hair before your finished dimension and then face off the shoulder, afterwords, to your finished dimension. It's especially helpfull when your turning between 2 shoulders, because sometimes it's real easy to overshoot the mark. It just makes things dummy proof so you can pay attention to other things, like safety., and you don't have to worry about looking at that dial guage at every pass.)

so - if "it is easy to overshot the mark" what happens when the carriage does hit the stop and try to keep moving - does it damage the nut, disengage somehow or what?
Thanks in advance :thinking:

PS: I often set the dial indicator so that it only moves a few thou before time to cut off - kind of a "soft stop"
