Milling and mounting for a red dot

Oh hi there you know about “farmer tolerance” too?
These guys that talk in tenthousanths can really be bothersome.

What is a farmer tolerance?? Tenthousanths? As in .010 or "tenths" as on .0001?? Most of the time ½ thou (.0005) is plenty close enough for me.......you guys forget I'm a die maker.

I have to laugh looking at what you are all getting done with the equipment you are using. We have all of the fancy stuff at work and still have guys whining to no end about how that can't do this, that, or the other.

I'm sure there are plenty of people laughing for different reasons. I can't say I blame them either. I laugh at myself quite a bit.

It was in reference to a comment I made earlier - my father in law is a retired tool and die maker, I’ll be in my shop fabricating something and he’ll be over there asking what kind of tolerance I need, and I have to remind him about hitch pin tolerances. As in, not rattle around too much.
I’m just learning, and I’ll also try to keep my sarcasm and joking in check.

All good! Kinda hard me to tell when someone is joking vs. Making fun of me.........

You can not thread an eccentric hole, thee entire hole is out of round. Normally you "turn " the shaft off center creating a cam or eccentric

Want to bet? I've seen it done. I guess if the tap fits, it's good, according to some people.
Would I do it? No.

I think I would have failed my apprenticeship (and gotten beaten by on of the journeyman Toolmakers)

A few minor upgrades. Digital depth gauge, reads in 0.002" and was pretty easy to install. Some machinist jacks, better than my homemade socket thingies.

CNC is tough to learn, but you can do so much once you master it. Basically make anything.

It's not that hard to learn, I taught myself, I need to learn 3d solid molding, (and post processing) so I can define tooling and optimize tool paths, thus generating cnc code, but I degress.......I can teach just about anyone to write programs I a short time

Bought a real mill and decommissioned the drill press from milling duty.

Rockwell 21-122 "hobbyist" knee mill. Perfect size for my garage.





First chips made today. Much better than the drill press setup. Two aluminum scrap pieces used for practice work, left is drill press and right is mill.

I see a few more optics cuts in my future, amongst whatever I else I decide to dive into.

Not OSHA ... NEC, National Electrical Code. *** Sheesh *** You'd have thought that I've been speaking a foreign language al this time.

 

[jwamplerusa]

OSHA would like to speak to you about the failure to secure the mill to the floor...
