I've got a few HMT projects on the back burner, which will turn up here eventually.
Just a few personal considerations/ experiences from my build:
1) Keep the probe arm as long as possible (minimizing angular error), and the base footprint length/ width as small as practical for your purpose.
2) My feet have probably a bit too big dia, smaller would be preferred just to smooth out the surface noise.
3) The differential screw makes adjustments much more easy and repeatable/ consistent than a coarse thread could ever do.
4) Use a handle of low thermal conductivity.

Keep up the good work and good luck!
Cheers & ATB

Retired? That will eat into your free time. One problem with retirement is that one usually becomes old before experiencing it.
Thanks for the tips. Nos. 3 & 4 were on my list, 1 Maybe?, 2 No I would not have considered that.
