@DuncanMiller, thank you for all this info. Im glad I didn’t try the tiny sapphire for breaking in the lap! Do you think WD-40 has significant advantages over the other oil options? I have my machine setup inside my house and two young kids, so I am trying to avoid fumes if possible. Thanks again for your help!
