big woots to the hamster for making progress! u lucky devil with that milling equip, that evap is going to turn out so nice. keep it up and keep us updated.
Well i can and prob will take it down another milimeter. The inside tube will then be 1/4" thick, wich seems alot tbh. But adds to the mass and provides a very solid stem. Don't really want the thing imploding...
This is taking soo dam long because the 1.5mm cutting tools dad got were tool steel, insted of tungstan carbide (god knows if i spelled that right). Meaning they have to be re-sharpened every 10-20 mins of milling.
I think your cutter would last longer if you used some lubrication. Although the copper is very soft, pieces of the steel from the cutter become embedded in it causing it to wear the cutter.
