iPhone SE - all you need to know

The iPhone SE is the latest 4" smaller iPhone, which is a successor to the hugely successful iPhone 5s. This is an iPhone 6s in an iPhone 5s size. A definite buy for someone interested in a compact iPhone with all the goodies of the flagship iPhone 6s series.



The iPhone SE was launched on March 21. It will be available for order starting March 24 & the deliveries start March 31.



The iPhone SE comes in Silver, Gold, Space Grey & Rose Gold colors, in either 16 or 64 GB at a price of $399 & $499. There are various contract options available as well, so check out at your local store or online.



I am very pumped about checking the real thing out as soon as it launches in my location.



Keep it simple stupid.

Centering on a 4 Jaw Chuck using Marking Block

Centering on a Jaw Chuck using Marking Block/Surface Gauge is one skill which a good turner needs to master in order to do precise jobs on the Lathe. 



It is a bit tricky at the beginning but as one gains experience & practice, centering becomes fun & a lot of machinists take pride in their centering skills (including myself :P).



I have tried to demonstrate how one can use a Marking Block/Surface Gauge for Centering on a 4 Jaw Chuck. Would love feedback on the video, if it was helpful or not. I will be posting a video on dialing a job on a lathe, soon.
