Grinding small parts perpendicular

Taking a look at a toolmakers cube and the common side grinding technique for squaring parts.

[@roseroserose588]

I really love your use of big paper models to demonstrate what you're doing - it makes the process so much clearer especially with the separate colours

[@EitriBrokkr]

Agreed!!!

[@trumanhw]

Exactly what I was on my way to comment ... Even better? Imagine all the wasted work it'd be... Trying to ANIMATE THAT (for no benefit, either)

[@StefanGotteswinter]

Great explanation, thank you! I love your grinding videos.

[@wktodd]

I like the way Adam make these videos. Expertise without arrogance

[@InheritanceMachining]

Theres a lot of great info here and you explain it very clearly. I'm especially intrigued by your "short" squareness comparator. Thanks for sharing!

[@mattgrady518]

Are you referring to the squaroll? I've got one myself. They do most if not all my squareness measuring.

[@InheritanceMachining]

@@mattgrady518 Yes! That's it! I have similar features on the surface gauge for squareness, but I like how low the pivot edge is on the Squarol. Thanks!

[@HM-Projects]

Adam's the bearded Dan Gelbart. Wealth of information in the videos ♥️

[@mattym8]

Yes!

[@Pete-xe3il]

While I don't have a SG'r, that tool makers block and back stop gave me more than enough to put one of my 246 blocks to good use on my mill for doing very small parts with light cuts. And as always, a great, well demonstrated and explained video Adam.

[@YulehHabibi]

They say he does the best paper cutout demonstrations in the entire midwest.

[@dan4653]

Adam, you are doing a great with these videos. I hope you can keep them coming. I'm seeing some neat stuff that I'm not seeing elsewhere. Also, your production, lighting, paper models are just spot on! Thank you for putting these up.

[@JFirn86Q]

The over-exaggeration of angles/differences helps so much when describing these principles, like you did with the paper models and the shim. Nice video.

[@624Dudley]

Thanks, Adam, love your style. The visual aids are best-in-class. Please keep doing what you’re doing! 👍

[@465maltbie]

Your cutouts are helpful, thanks for taking the time. Charles

[@jewishmafia9801]

I'm not a machinist but I find this stuff fascinating. I do woodworking and this reminds me the technique of always having a reference surface to work from to ensure squareness, parallelism, etc.

[@ambisinisterengineering5242]

Really enjoying the way you explain these subjects and demonstrate them in a clearly articulated manner. Appreciate you taking the time

[@adamthemachinist]

Thanks for watching !

[@TheWidgetWorks]

Thankyou for taking the time to make these videos. I would never have thought to just check for squareness that way, this will make my life much easier in the future. Also Love the toolmakers cube 'vise' setup. Makes me want to design a heavier vise type that has adjustable high jaws for milling work for the number of times I've had to make soft jaws or custom height parallels so that I could hold a part just so.

[@flintstoneengineering]

I still find it amazing that such a small point of contact with so little pressure can hold the part against the fence. I know your not hogging material off but I can't help but squint in anticipation of a crash. Presumably you develop a feel over time. Thanks for sharing

[@harrisonaero]

[@aronnootebos805]

[@markjohnson9884]

Great video on how to hold small parts. It looks like the next tool I need to make is a cube, like the idea of the fence being adjustable. What about a video on grinding aluminum? I’ve watched the one SR did, even bought the wheel they recommended. One part I make is 4” x 2” one side is flat but needs to match up with the V-Grooves on the opposite side.

[@LetsRogerThat]

Thanks Adam. Gilles

[@tinayoga8844]

I love your videos. Always something to learn. One thing though. Audio levels are a bit inconsistent. In parts I need to turn up the volume, then quickly turn it down on another segment.

[@SELG88]

good vid.

[@tonycerniglia4777]

Adam... How about a description of how to make the machinist cube (process steps in order). Saw, Mill, Drill, Tap, Heat Treat, Grind. I don't think you actually need to spend the time and actually make a second one, but going through the steps (and your paper models, WHICH ARE FANTASTIC BY THE WAY!!!!!!!!) would guide those less knowledgeable in the specific order of operations including stock to leave for heat treat movement, etc., etc.. Your delivery of content is done in a way that is comprehensive and basically, if one can make this cube CORRECTLY, fully understanding the steps and the why behind those steps, then there really isn't much in the way of typical square and flat work that can't be done... I think. Oh, the milling could be done with description of manual Bridgeport and then by CNC pathing around and then flip over to cut the deck off. Regardless, your doing a great job with this... we need more youth understanding HOW TO MAKE and then spending time with a spindle turning and their hands on a crank wheel.

[@dan4653]

Ya know. Someone should do surface grinding techniques series... :) There's a lot I've picked up, but a lot I don't know yet...

[@ls2005019227]

I agree. Stan (shadonhkw Bar Z) has done some way back [called "The Grind"].....Adam here is doing a fantastic job.

[@wishbonebrewery]

I used to use a fixed square block and a DTI to check for square then work to ultimate squareness (and Parallel) then end up using cigarette papers as shimming under one edge before a re-grind, or even a line of Permanent marker pen then a re-grind. Made some crazy accurate shit in one job.

[@chrisburbank6484]

how about a video making the tool makers cube?

[@jesseservice7828]

Perfeito !

[@BrettFleming]

Love the videos, fascinating to watch and learn from. If I could offer a small piece of advice, add a "trailer" or something to the end of your videos. KZbin likes to display related videos overtop of the last couple seconds of each video, and it can't be turned off. Unfortunately for yours, it hides the last check you made.

My dumb a** thought you were using a pencil to tighten the rib there. 🤨 That said thank you as always for the insight; I truly am a freshman in a grad class here but I'm taking notes.

[@roseroserose588]

I had to go back and re-watch that section, I also thought that was a pencil 🤦🤦

[@oxtoolco]

Nicely done. That is a cute cube you got there. All the best, Tom

[@AndrewBoraas]

I have a bad habit of knocking on parts with one knuckle to feel if they are down in a vise or on a fixture. Its really easy to tell if theres the more boney dull thud of the machine casting thru your body or, s tap or click from the part. But its to easy to hurt my knuckles. I should see how I like a piece of wood.

[@tubalcain1]

Hey Adam thanks for the informative tips!!... what brand of comparator is that sitting on your granite plate?

[@adamthemachinist]

Squarol

[@VegaMaker]

Thank you very much for your videos! What the surface grinder are you using? It's so quiet.

[@adamthemachinist]

It’s a Parker Majestic , the spindle was recently rebuilt by Sopko , so it’s still pretty quiet

[@frank03s]

Took me way to long to realise that was not a pencil been used

[@vandewallede]

lol. I’m really glad it wasn’t just me!

[@jacopoandreo8776]

Really fantastic video! Quick question about the cube and in particular about the clamping screw. How did you determine the best angle for the screw itself so that it clamps both down to the block and against the rail, and I saw you tighten it with a very light pressure, but would not a small block between it and the part spread the clamping pressure and avoid any warping while allowing for a more secure (higher pressure) clamping? (in particular on flimsier or more complex parts)

[@adamthemachinist]

I’ve played around with the angle a lot in my career and I haven’t found there to be an exact angle that works best, just a gradual angle pointed down is fine. Some toolmakers I known don’t bother making the clamps adjustable , they just tap a hole on an angle . As for a clamping block , it certainly wouldn’t hurt but I get by fine without it .

Is the tip of the screw hardened, or is it just a piece of mild steel thread? Very informative video. Thanks

Its just a regular SHCS ground to a cone, they peen over with use and I periodically touch them up. I've played around with different tips even some with ball joints , all are better on paper. But a regulars screw ground to a point work very well and arent fussy to make

[@adamthemachinist]

yep, the shop has parts going to heat treat once or twice a month so all tooling just gets tossed into those batches

[@TheMudfly80]

Hi Adam, I have a similar set up to yours but without a grinder (cnc mill/lathe and manual), I'm just starting out. Do you think a grinder is necessary? Also if you were purchasing a second hand one like yours, what sort of variation would you say is good over the entire x travel in flatness or other specs? Thanks.

[@adamthemachinist]

It’s hard to say how necessary a piece of equipment is without knowing the work load. Being a tool shop I do lots of hardened steel and it’s very important to be able to grind . But a shop that does non ferrous may not see any need for a grinder

[@sblack48]

Is your tool maker’s cube shop made or commercially available?

[@adamthemachinist]

Shop made, I haven’t seen anything like this commercially available. Surface Grinder tooling is a hard market , anything you’ll be making is attempting to be sold to people that have the equipment to make said item . So you see lots of shop made stuff and only the very common stuff is sold commercially

[@StefanGotteswinter]

Hemo makes something like a toolmakers cube for squaring. But a lot larger.

Hi really enjoyed the video. Did you make the tool makers cube? Or did you buy it. If you made it do you have drawings for it to share?

You wouldn't have a print or a solid model to share would you?

[@edpopelas2844]

👍👍as always. I recently as this question to Mr Crispin and I’ll ask you the same. I often see folks using a test indicator in the “fine measurement range” (0.001” - 0.002”) using a indicator with 0.0005” resolution. I have to wonder why they wouldn’t use an indicator with 0.0001” resolution? If this is a piece of equipment you are likely purchasing new (dollar for dollar) wouldn’t you go for a finer resolution? Seems you could get a more accurate assessment of a situation with a 0.0001” indicator vs a 0.0005” indicator. I’m sure there is more to why these 1/2 thou indicators get used but is there something I’m missing? Are tenth indicators more susceptible to damage and 1/2 thou more robust? Or could it be for hobbyists there is a large available of these on the second hand market?

[@crewdawg257]

You’ll will drive yourself nuts chasing the needle on a .0001.

[@oxtoolco]

The total range of a 1/2 thou indicator is much larger. For general work they really do most of what you need. Tenths indicators have a small range and when doing normal indicating chores are much too sensitive and lack the overall range for say dialing in a bore on the mill. Once you get on the surface plate that typically changes but it also depends on the class of work you are doing. If your flexing and using a tenths indicator on your Bridgeport you are fooling yourself into a false sense of accuracy by way of tool resolution.

[@ScuffedEngineer]

Surface roughness also plays a factor into chasing the needle on a 0.0001" indicator, Adam's work could probably be fine for it, but for most a 0.0005" is fine. And to your final point, they're cheaper than 0.0001" indicators.

[@adamthemachinist]

Lots of fine points listed so far . One more thing that makes a .0005 worth having is it’s lower gaging pressure . If you have a flimsy setup the gage is actually deflecting the part. This is handy if doing something like indicating a probe tip. You can have zero indicator movement on a renishaw probe and switch to a courser indicator and suddenly see a little runout. The gage pressure of the .0001 is pushing down the high spots of the ruby probe tip.
