In the future i think Im going to invest in some HSS more so for the finish. Ive only had carbide inserts and never used HSS other than on my parting tool, which i have to be honest, i struggle with a bit, not sure if its technique, my machine or my tool. People says parting off is a bit of a "black art"....comes with practice i guess.
So, ive just spent a few hours making a "button" for my bottom cap.
Turned out great, i turned it with the face of the button out so i could get a nice finish on it with the stem running back to the chuck (see image).
Problem 1 > Stem isnt long enough, user error my fault.
Problem 2 > Parted off, let a "nub" as the parting tool wasnt central (user error) so tried to take this off by putting the part back in the chuck which only led to it coming out. Stupid, wont do it again*.
Problem 3 > Recess in bottom cap isnt deep enough to take a good length of travel for button, so either a) Will remake that part or b) machine the part out a bit more.
I guess once i have everything right, repeating the process will be easy, my drawings didnt work out to well other than general dimensions and ideas, but a lot has changed as ive gone on making various bits and pieces, it just keeps getting more and more complex! LOL but making easy piece is getting easier and easier now im getting comfy with it all

*this does not mean i get the parts right though!*
Also made a brass drip tip for a change of pace, which works great, bit of a VERY snug fit on my tank but works well

Also added a picture of the man den, could do with being "spruced up a bit" needs a feminine touch i think, ill get the Mrs to go in there at some point! lol
