Our company is all manual because that's the only way it can be done efficiently. We rebuild or reproduce better than oem parts for the internals of natural gas compressors. We get oem stuff that came from a CNC line that is garbage and have to rework a $10k dollar part so the engine won't vibrate all to hell. This is not little 4" pistons either. Some of these are 24" diameter and the customer wanted it yesterday type deal. There's not a single job we handle that a CNC can even touch in efficiency compared to manual.
The only time CNC is better is on high volume runs and extremely intricate parts.



Carter Fab & Machine: Hand Made Customs

perhaps you're in a niche-- being surrounded by bad CNC operators. I simply disagree. On the other end of the spectrum, I prototype aerospace parts all day long. While I agree that CNC's excel at high volume runs and intricate parts, there simply isn't a scenario where manual has an advantage. Any decent CNC mill is equipped with a manual pulse generator. It can be used in the EXACT same fashion as a manual mill, so how could a manual mill POSSIBLY have an advantage? The logic is simply flawed, and isnt worth arguing over. I have no doubt you're a superior machinist than the people whose parts you are reworking, but it has nothing to do with the equipment. You're quite literally arguing that the typewriter is better than a computer-- on the basis that YOU can type faster on a typewriter, than someone who cant type on either.

Anyhow, enough shitting on dude's thread.

I have the pro-stop at work and have never been impressed (especially for the $$).. Snapjaws, on the other hand, have been worthwhile. They're quick to take on and off, and have end-mounted stops that repeat very well.

So I can say I have been doing this for 25 years + 10 years growing up in 1st and 2nd tier silicon valley machine shops my entire life.

And I would never say that a manual is better at everything. I would say it does have some advantages for short run and quickies, basic square and cylindrical parts, But as soon as you add any shape or complexity you lose your advantage very fast. and soon as you want two of the same part, again you loose ground very fast. Its better to have both at your disposal. If i had to choose one, The cnc would win every single time..

and of far as accuracy .... super accuracy ( sub .0001 inch) can be done on both machines, it requires high skill on both types to do it. The cnc makes it much easier..

We make our prototypes on the VMC for that very reason, but if changes are required, our knee mill usually gets the job so I would have to agree.

I would also like to add that not all manual machinists are highly skilled, and not all CNC machinists are nothing more than button pushers. It goes both ways.

Wow Chris, your thread has turned into a documentary on machinist's , I thought it was for making cool stuff for what you want and to share what you learn.
Your vise stop is a great project by the way and turned out cool .
I do want to make a couple of those little machinist jacks, I needed one yesterday with a long piece of material I was fly cutting.

Another idea.

Soft jaws......Cut your part stop right in the jaws. Something like 1.25 x 2.5 x 6.00 6061-t6 works good. When you move to the next project you just cut the jaws down and start fresh or reuse your current setup.

Yeah, god forbid a thread that I'm involved in gets derailed.

Thanks, v2 is way way better than v1. I think a jack would be a good idea too, though I haven't had to work with anything that would need it. Can't ever have enough tools!

here's one tidbit

you can use your mill as a lathe,

put the lathe bits on the vice, and stock in the chuck..

Been there, kinda.

Put an old endmill in the vice and some round aluminum in the collet. Made a dead center.

Haven't been doing anything too exciting. I did figure out how to make my gt3b triggers without them breaking or flying across the garage though.

Got a couple guys I race with that broke their triggers as well, so these are for them. Since they are better than the one I have, I'll have to make another for myself.

One is grey pvc (attempt #3), the other is acetal (attempt #4).

That's it. I'm going to have to invite myself over sometime. Would tacos get me somewhat near the mill?

Maybe. You might have better luck with a quesadilla. A Flying Burrito would be a guaranteed win.

They aren't too bad. Still takes me longer to make than I'd like though.

Carved out a brushless motor mount for my CRT .5 project.





Since I don't have a boring tool I couldn't make it like the store bought stuff that doubled as a diff support, so I decided to make it wrap around the existing support. It'll bolt on where the brake assembly used to be, and another bolt at the motor end through the chassis plate. Should keep it from moving and changing the gap between the spur/pinion.



I also noticed my table is getting really wonky. Probably time to tear it down and see what is what.

Wonky....? Your getting way to technical with your vocabulary.

Was that an existing piece you modified or was that a raw material project? Looks great

Part of my 2012 New Years Resolution was to expand my vocabulary into the techniferous region. I'm doin' real good too.

That was just a chunk of aluminum I dug out of the scrap bin.
