Hi Alan, nice to be here. we like the build as it shares like a how it is made and how it works as you build this machine probe. Thank you for the share, Lance & Patrick.

You have done a fantastic job making this prob Allan, quite a lot of fiddling around to get the led situated correctly with out the connection touching together in such to small area, a lot of thought would of went into designing and making the components for this, a credit to you mate, a bloody top job, thanks for sharing this, I truely enjoyed following along Cheers Matty

Good job, Alan. You may want to put a 1\8 watt resistor of 5.6 to 6.8 kilo ohm in series with the LED. This will drop the voltage and limit the current, so the LED only draws about 20 micro amp's This will make the batteries last longer, also protects the LED Adam

Nice works great.

Very good! Works well. Did you ever determine why the chuck was running out? I had a similar problem with the chuck on my Chinese drill press, inspection revealed that the taper bore had been wrongly machined and I had to scrap the chuck. Replaced it with a Jacobs which gave a run-out of 0,001"

Cool work 👍

Not long purchased one but I think I'll also make one it's an interesting project !

Good job.

Great work just bought one off ebay $ 16.00 delivered the ball is spring loaded, it beeps and lights, the exact same thing in the Hare & Forbes machine book $93.50 + delivery accuracy 0.005mm check out there web site. But nothing beats making your own stuff cheers from OZ.
