Mark Cason and I have developed an edge finder that simply connects to many brands of lathes with no modifications to the machine and detects when the tip of the cutter comes in contact with the workpiece. Accuracy is better than +/- 0.0001".
Eventually it will be offered for sale by Mark's daughter. But for now we want to be sure it works reliably and has a good user interface. So we are enlisting beta testers to help us test it out.
You will receive a Lathe Electronic Edge Finder, Model 1. Mark Cason will cover the cost of the device plus shipping within the USA. You will also receive a draft of the user's guide from me via email.
In exchange, you must commit to using the LEEF at least 3 times a week starting in the week you receive it and ending when your results are consistently good. You must take detailed notes on your experience and email these notes to us within a day of each use. If the device fails to work as expected, we reserve the right to get it back for study and will ask you to take data from your lathe.
We also expect you to read each version of the user's guide and supply us comments and suggestions on making it better.
To qualify, you must have a lathe with a spindle resistance greater than 3 ohms. Details on how to take this measurement will be supplied upon request.
Thanks!
