When using a shopmade tool or my method, ensure that you thread fully into the pin to prevent problems.
As far as the tool exchange program goes, I've already tried that with disappointing results. Almost a year ago I UPS'd a tool that cost over $100 to someone that was a frequent poster on MShop. He has since stopped posting and I have yet to see my tool returned.
I also have loaned out a meter, but that was someone in my home area that I know reasonably well. I am sure I will get that one back.
Have a great day,
