@Janger : I have followed him for quite some time. There is a video where he explains his relationship with the place he has access to the “fancy machines”. It used to be his company. He sold it, but they call him in for all the special, intricate, limited production run stuff. He mostly runs a big MAZAK for them. He has a small private shop where he has a HAAS lathe and also does some blacksmithing.
The main purpose of me citing his video was to show what is involved to make an EM.
If you want to recondition a used one, about 75% of the set-up steps still need to be followed initially for each size and model of EM to be redone. Hence the rather high price for regrinding. All Blade Inc. basically said that for anything less than a ~$50-75 tool, it is not economical. They will probably still do it for you if you insist and decide to sharpen a $10 endmill, but why would you?
As stated earlier, I am collecting my dull EM and drills. At some point I will set up my manual T&C and sharpen them. Mostly for my own practise and learning process. If I can get them back to a functioning state and get some more miles out of them, great. If not, we’ll so be it.
