Wall thickness guage

[Dean Freeman]

Tom,
Thanks for the photos. Much easier to make than I would have thought. The bead on the end that goes into the barrel; is that a made/found part, or just a polished welding bead? Do you have any steps worth mentioning in the building process that would help a layman, or is the process of building as straight forward as it looks? Also, did you find a certain size rod that worked better than others?

Thanks again,
Dean

The little bead is just a polished bolt head , the bolt is through the rod and cut off.
For the horizontal one, I just chopped up a ground rod for an electrical panel used in a house, Home Depot or Lowes sells them very cheap I think in 8 ft lengths or so and they are very stable. The rest is just what you see. It's very simple.
