Lathe tool height gauge
What do you use?
I've seen a few on U Tube and am thinking I might make the gauge like this:

I use one of these https://www.ebay.com.au/itm/Mini-Dig...frcectupt=true it has multiple uses but i seem to use it for tool height setting mostly.

Hi Steve, Guys,
You may recall that I made one a little while ago

A simple 30 mm diameter pillar turned to the centre height with a cap so that you could set the rear tool as well. Nothing complicated at all. In fact made from bits out of the scrap bin.Best Regards:

If there's nothing in the chuck yet, put something in and face it, with a rough guess at centre height.
Adjust and repeat until perfect - no tool needed.

Centre in the tailstock, then if it's super critical to get it perfect.

I've done the rule and tailstock thing. I've always had to do that way, or take cuts and adjust, etc.Don't really care for it anymore.
I like the idea of having a gauge and being able to quickly check it its correct or not, with your nail.
Not having seem anything better, I think I will go with the height gauge. Have ordered a magnet to mount in the bottom as I will use some Ali round bar I already have.

Hi Steve,
I wouldn't bother with a magnet !
Two reasons, The gauge simply stands on the top slide, I just give mine a wipe to make sure that there are not any bits under it that could cause it to tilt. And the magnet will pick up any ferrous swarf near by. I've just recalled a third reason the magnet will magnetize everything in its vicinity.
When setting a tool height I just slide the gauge ever so slightly towards the tool tip, if it catches the tool is too high, if its too low the gauge will rock slightly. I set the rear parting off tool so that the blade tip just touches the top surface of the column not the cap.
HTH.Best Regards:
Baron J.

This is my method. Set the calliper to centre height (130), hang it on the tool edge and it should just skim the bed.
