Making a motorcycle chassis or this is what tools are for.

Fascinating build log Tony, your attention to detail is inspiring. Looking forward to seeing more of your new engine build,

Alan,

Not much progress on the engine. It was a long hot summer, too hot to spend much time in the workshop. So I tried to stay cool working in my office, catching up on some software upgrades and some workshop related programming and electronic gizmos, as well as preparing a new version of the book.
A year or two ago I bought a 1 micron linear encoder for a cam profile measuring device. it didn't get a lot of use, how many cams does one need to measure? I thought that the addition of an LCD display would let me turn the encoder and its black box into a general purpose accurate comparator. When used for cams there is no need for the display because the data is shunted off to a PC for analysis. I added a switch to change functions from one to the other. Here are some pix.
