I have made some 1/4" thermowells from tubing I got from grainger..http://www.grainger.com/Grainger/Tubing-3ADU9
I used a hacksaw to cut 4 angled notches in the tip and bend over into a round shape, TIG shut, and grind/polish smooth.. not happy with the time taken to make them and with the appearance of them..
Anyone use a lathe and some sort of tool to 'spin' or 'turn' them down to a rounded point? Was thinking some small bearings mounted in a MT-2 tailstock for my micro-mark lathe... (similar to a knurling tool) I have lots of ideas, just wanting to see if anyone has put them to practice...
optionally, anyone seen pre-fab tubes that are cheap (less than $5 for 6-12")?
