Measuring for Parallelism Using the Granite Surface Plate

Our freshly machined hardtail vise swivel plate is set on the granite surface plate and inspected for parallelism. This was a simple inspection using our granite plate and dial indicator to see just how well our lathe fixture worked for facing off the bottom side.

this is a demonstration. he said fun exercise which is a perfect explanation. the channel is both informational and entertaining. yes the vice project is ridiculous over kill. but thats exactly what its supposed to be. i enjoyed the vid

Can you make a video on how to calibrate with precision - hammers & drift punches before use?

[damionparson]

I really noticed how you set your zero based on the variation of the tool marks. I don't remember that being explained to me years ago so I appreciate you for making this video.

Thanks, Abom!

I'm sure this will end up the most precisely machined vise in existence. I'd never want to use it after all that work!

I worked for Boeing in Seattle many years ago as a jig builder. One of the coolest places to work was "the gauge room". We worked off of two foot thick, massive granite tables in a climate controlled room with a max tolerance of .002. Good times. In the day, MEK was the choice chemical to clean the table...probably not a good idea nowadays. Thanks for educating the masses Adam. Great demo!

Adam, not only are you an amazing machinist, Master Class imho, but the quality of your presentations, instruction and professionalism are spot on! You have REALLY become a Master host!

I love that big indicator base. I just noticed it's dovetailed on one side and t-slots on the other. That's cool

Somewhere, in a CNC machine shop, Cryin Steve Colluns is being reprimanded for using every last pig mat to absorb his tears because he can no longer troll these videos.

Adam you have a gift with the way you explain a technique and the principles behind it. You my friend are a great machinist but an even better person. God bless you and your family.

[seanlancaster]

Absolutely love seeing this process. It still amazes me how simple and easy you make this look.

[therationalanarchist]

Really appreciate it. I don't work in the tool room at work but I am a machine operator and I have to measure parts that we produce using digital calipers and a digital height gauge on a reference surface, similar to your setup but my surface is smaller. Thanks.

[billbubnis]

Thank you for educating and entertaining me tonight Abom!

[RobertGracie]

These videos are just awesome, its a great way to see inside your mind and how you measure things like this! Precision all the way!

[dougzachary]

Adam. You’re awesome. Thanks for sharing this info with the interwebs.

[francisschweitzer]

Considering it was a big ole interrupted cut and it was singing like it was… that is really good.

Like you said, it’s a Vise Base.. and most vises get bolted to tables that are in less then good shape..

[flinch]

A good show of tolerance stacking. There's what the lathe/tool gave, plus instrument accuracy, plus even a great inspection plate isn't perfect. Considering the initial chatter problems of the cut, this did turn out fairly well. Chasing more probably winds up at surface grinding but... this piece isn't going to space.

[clintchapman]

That's awesome Bud! I'm happy for ya'll!

[misterikkit]

It's delightful learning from your videos

[emiliodelgado]

you could check it on another side of the table and see if is the peace or the table have a diviation

Nice to see the big rock earning its keep!
