The M head isn't the worst thing in the world. For strange work where it's required to move the head in every direction known to man, it's quite nice to have. J heads are much heavier and awkward to...

Great price with the turret

McCarthy's is always a great place to eat; their burgers are great. I've been there at least a dozen times.

Thanks for the links, guys.

We know they're going obsolete, and that's part of the problem. The handheld programmer we use hasn't been made for 20 years. This will be the first program done by...

Retracting the wheel fully out the part can create a bell-mouthed bore.

That sucks. Those controllers weren't cheap back then, and they still aren't. They don't last forever, either. We burn them out after a few tens of millions of cycles. Inputs and outputs go bad...

My boss has 3 employees and we work out of a space around 1000 square feet. There is no payroll department, and no budget or timeframe to take a semester of classes just for programming. I make under...

While I don't know the exact financial status of my employer, we don't have the kind of money for that. I'm also leaving in August to attend the University of Akron's Automated Mechanical Engineering...

This machine is a duplicate of another, and for the most part we've already managed to copy the code to the new machine (using a handheld programmer) however it's stuck in one place. I also need to...

The company I work for uses A-B Micrologix 1000 PLC controllers to run any machine we can't run on switches and relays. My boss's brother in law, an electrical engineer by trade, used to program...

That kid shouldn't be in that course. I don't think many seasoned hobbyests could do that nice of a job.

Is that a blued or color case hardened finish? If it's the ladder, you'll never get the finish to match over a TIG bead fill. If plain blued, you can probably get it real close.

A friend of mine had me turn some aftermarket rear rotors for his racecar. EBC wanted quite a bit for a new set. I think they ended up within .002" in parallelism and he had no problems or fluttering...

I know a mechanical engineer and he calls .100" incriments​ "tenths". I almost fell out of my chair when he asked for some 3" aluminum parts turned to a tolerance of half a "tenth".

I haven't had the chance to see many shops operate aside from the one I work at, so please take this with a grain of flour (smaller than salt, heh)

Woodworkers have been using conventional router tables for decades. The cutters are designed to work with high speed and slow feeds. Most CNC machines can feed faster than people feed material on...

Consider spiral downcut router bits if you're having surface chipout issues. Max your spindle, no point in running a router bit under 20k if you have the capability. Use an air blast to remove chips...

Usability of pneumatic scrapers aside, if I were to built a pneumatic/hydraulic scraper Id use a master and slave cylinders to control movement. Connect the master cylinder to some sort of...

I believe match chamber spec for a .22 is around the .038" range, so firing pin protrusion should be around .030''. My Anschutz 54 is about that.

Dry firing is dangerous because you can break...

That might be the case now, but until fairly recently it was one of the primary tools used for off jobs. Internal splines for example.

Please be aware that if you profile turn a button rifled barrel, it can actually spring open and increase bore diameter. This is how Anschutz chokes their smallbore rifle barrels. After button...

Have you considered posting a sign that shows general shop rates per hour?

Reminds me of a method called explosive forming where you use expanding gasses from an explosive charge to force a piece of sheet metal into a female die or form.
