After some discussion with the good folks at Metalworkingfun.com, I decided to start off the job with 4mm SS rod instead. The opportunity to buy the SS rod came when I was sending my car to the workshop (Toyota Recall Exercise for the drive shaft). Bought a piece of 4mm dia SS rod of about 500mm length. I asked if they can cut it into 80mm piece. The lady looked me into the face and said, "We'll charge you SGD 5 per cut". The rod cost SGD 10 before tax and since I've a bandsaw at home, I thank her for the offer and pick up the piece.
I didn't finish the job today as I realized after drilling the 2.1mm diameter hole that I don't have any tap smaller than M3... Lolz... So I turned down one end to the required 3mm dia for the fun of it.
There will not be any update for about 2 weeks. My wife and I will be going Israel with our Church. I'm sure we'll have a great time there. I'll continue working on this job when I get back, before going back to my day job on April 1st.
Meanwhile, be bless!
