Radius gauge and reverse engineering

[Toolmaker51]

I recently posted about some reverse engineering that I needed to do to replicate some classic motorcycle crankcases at

Continuing on from that I needed to measure some corner and other radii, there are many possibilities for such tasks, for example MichaelMoore recently posted his templates at

This current post is about a set of radius gauges that I built using a digital gauge as the measuring element.

I have put the full story in a PDF which can be seen and/or downloaded from:
Tony's radius gauge
I have also written a simple bit of software to perform radius calculations and that is linked in the PDF file. I will also add a video in the next few days.

I can't recall anything on the market or DIY anything like it. Seems Tony, you knock two thirds the competition off before they get in the pit let alone on track. Said other way; He's lapping them right inside the shop?

Further; Jon. Is there a HMT.net logo decal for Tony's machine? What an audience!
