1st Gen Lunchtable Thread - General Discussion

Totally jelly of it too. If I was out there he'd be my new best friend and then I'd make him take me so I could get practice.
Almost bought an old 1970s metal lathe, I forget brand but was industrial and commercial quality made in USA blah blah, like 10 years ago from a local manufacturing shop. It had very slight play, very very slight play but I had nowhere to set it up or store it at the time. This shop was just selling it to highest buyer.... It went for like 600 bucks

 

I'm a botanist & chemist at the same time!

 

Thats scientific

 

Jealous, if I could make a decent living gardening I'd be all over that too

 

Come to California, ik a guy

 

Once you get familar with all the controls that make's it easier. Then just learn how the machines behave (every machine is different) & how certain metals cut then go from there. When your lathe or mill doesnxt like how you cut something, it will tell you! Lol

 

We tried cutting something on the mill the other day but it didn’t make a strait cut. One side was canted so it didn’t mount strait. Gotta figure out why

 

There you go. And you have the skills for troubleshooting and and analyzing and thinking things through.
Best thing I ever do when I need/want to learn something is join an online forum. You can do or be whatever you want with forums now

 

Still have my CD. Likely won’t ever get rid of it even though I ripped it to mp3 like 10 years ago.

Kids these days and their “music”. Get a haircut and get off my lawn!

 

I'd have to see the setup (how you held the part), the cutter, & what the cut looked like to be able to offer any tips. But for milling, look up convention vs climb milling & get familiar with that. Generally you don't want to climb mill on a manual mill, especially if it's old & has wear. There are exceptions where you can climb mill but generally it best to conventional mill.

 

We tried to cut a notch in some square stock we had. Just made a few passes to make the notch one side of the notch is 90° the other side is more like 110° So it didn’t mount right on the plate

 

Again not sure what was going on but was the vise trammed in? Anytime you take the vise off the table & put it back on it needs to be trammed (set in line with travel of the X axis on the table.

 

I don’t remember. Would have to goto the shop to show you

 

Idk

 

Doing it the old fashioned way with a Terry cloth pad and some wax. Wish I had a buffer but I don't really know how to wield one properly.

My dad is a master buffer is there is such a thing. He takes a dull cnc machined brass ball all the way to mirror finished lol. He spends hours on that

 

she hasn't told you yet?

 

No, because she always swallows

 

not when I visit
