Micro DRO made from tyre tread depth gauge

No drilling of magnets. Made up a 6mm long tube with 3mm bore. One end slips over the probe the other takes two 3 x 1.5mm rare earth magnets. A dab of two part epoxy adhesive holds everything in place.

Just ordered 50 off, 3mm magnets..... £4.99. :thumbup:

I used my micro DRO again today to do some precision milling on the lathe and I can only say that it does an absolutely great job, regardless of the price. Very accurate.
This whole concept has really taken on a life of it's own, and it's good to see Madmodder kick it around to get the best possible outcome from the original idea.
Maybe one day we might even see a commercial unit with the same capabilities.
This is good discussion group with a good attitude - and it's a refreshing change.

Just note that digital thickness gauges have been showing up of late on ebay:

It appears to have a very similar body to the thread depth gauge discussed here - and would be so if bits were milled away.

Unfortunately it only has a 1.5 battery, so readouts will probably be slower.
Still, it has potential :smart:
