I finally took the time to machine up a dead stop for the lathe spindle. Certainly makes for easy and consistent lengths when required.
A batch of boiler tubes seemed to be the ideal job to try it, so a bit of 50mm round bar was sourced and machined down to suit the thread in the rear end of the lathe spindle.
Thread cutting involved a bit of measuring and a bit of guesswork to get the plug to screw in, which is now a nice fit. The plug shoulder tightens up against the end of the spindle.
The end was machined from an offcut of bronze, and a 3/8" thread bar installed for setting the length. It will also fit inside the chuck for those short jobs.
Very easy to knock one up, worth making one if you have a few parts the same such as axles, boiler tubes, etc.
