Squareness Comparator - surface gauge

Fantastic design. Brilliant. I can see this offering helping many new machinists. 👍👍😎👍👍

I just found this video and will be making one of these! Thank you for taking the time to share your video and your STL files 👍

Great video as always Ray, probably some of the most impressive 3D printing work I’ve seen from you. Although additive manufacturing isn’t in the curriculum I hope your students take something away from this! A very useful tool that would be very expensive to buy or machine yourself, this is the type of project that is perfect for 3D printing. Cheers and all the best!

Hi Kyle thanks for the awesome comment Thank you Ray

Very nice and informative video.

I like the squaring math section at the end of the video. Thanks :)

Nice Squareness Comparator. The file links seem to be dead. Have you thought about setting your files up on Printable or thingiverse. Would love to do this build as I am a hobbyist and Squareness Comparator's are quite expensive. Keep up the great work!

Great job!

Thank you for the excellent video and for all the work you put into designing it - and especially for sharing it all for free! To give credit where it's due, I found your chanel because of a video by back_yard_machinist, who is using one in a video he just published; "Surface Scraping Grinding Fixture".

I will have to check out that video and thank you very much for taking the time to comment it is greatly appreciated Ray

The link for the 3D print files says it has been removed. Is there any way to access them somewhere else?

Nice work. I like your iterations over the years. I'm working on a custom indicator stand to measure the roundness of billiard balls, using a tenths indicator. I too have had a few iterations over the years. My middle ones combined 3d printed bases with 3 bearing balls for the billiard ball to rest on. I'm now aiming to have it laser cut aluminum, which is very cheap at sendcutsend. I found the 3d printed versions flexed a bit too much, and affected the measurement using a tenths indicator. Your design reminded me a bit of mine.

[@raygallant8224]

Hi nick It’s an interesting concept I never thought of tracking roundness for billiard balls Just reading this I pictured something in my head how I would do it Using for digital plunge indicators Thank you for taking the time to Comment Much appreciated Ray

If you decide to print one, send me a photo I would appreciate it. Thank you for taking the time to comment. Ray

Great video, thanks for sharing. Can you fix the files link, please? it looks like it's broken.

[@shopandmath]

I have a new version. If you send me an email at shop and [e-mail] I will send you the STL‘s for the new version. I have not made the video for it yet. It’s coming early in the new year. Ray

[@sto2779]

Can this be used as an accurate "squaremaster"? 20:27 - Good god, a precision machinist using $500 precision test indicators on 3D printed surface gauge makes me really want to make this and think of it as a professional instrument. Thanks for this great contribution.

[@akisdrosos]

Hi! I love this idea and im amazed by your channel! I live in Greece and i can find any of these diameters here.....Is there a way to share with me the solidworks files so i can change the sizes of the bars to 12mm, the size of the screws, washers etc? I love to make one and i cant either find this type of tool in Greece, only magnetic holders! It will be great! Thank you in advance!

[@bobvines00]

Ray, can you make your SolidWorks files available too? Now that I'm retired _and_ don't have a 3D printer, I'd like to (maybe) tweak the design for my machining capabilities out in the workshop and then make up drawings that I can use as an "exercise" to improve my shop skills (and add a useful tool too!).

[@philipmoore9951]

Excuse me if I missed it but is there a list of the hardware you used like the spring etc.?

[@shopandmath]

Sorry I missed making a hardware list or I should say adding a hardware list

I just wrote a novel with a lot of ideas and links and I think it didn't get posted:(

Love this device, awesome piece of work. I was a college instructor at one time and I know that what you have produced is the result of being incredibly motivated to help your students. I'm sure you haven't been paid a nickle to do any of this work. It was all done of the edge of your desk for your students. I would love to print one of these but I can't seem to get past the sign in to the college. Any advice on that? Keep up the good work.

[@shopandmath]

OK I will double check to make sure that the files are available and update the link

[@shopandmath]

I change the link and it should work now test it out and let me know if it doesn’t work

[@rossholden6752]

@@shopandmath Thanks, works perfect, goes straight to the files. Thank you for making these file available to anyone.

PLA in the machine shop?? Just the ringing on that printed part tells me you haven't calibrated your printer very well. PLA seems like a questionable material choice at best. Those threaded holes are "easy to tap" because they're easy to strip. PLA has "creep", so any part of that part that is unsupported is going to start deforming and ruining the repeatability of measurements

[@shopandmath]

PLA works great in the shop depending on what you’re making. you need to be selective with choosing the right tool for the right application 3-D Printing is awesome under the right circumstances stress and heat seem to be the enemies creating static moving parts work well for non-load situation For non-loadbearing, threaded holes, tapping straight into the PLA works great if there is some type of load using a threaded insert or not is best practice The oldest surface comparator is about seven years old now, and works as good as the day I printed it There are a couple modifications coming up in future plans changing out the 1/4-20 adjusting screw for a 1/4-28 (a fellow commenters suggestion) lengthening The indicator arm and setting back the adjuster screw for more clearance compared to the risers And also including a security tub to feed and a small one 16th aircraft cable through so that if it gets bumped off of the surface plate, it won’t hit the floor Thank you for taking the time to comment. It’s much appreciated. Have a good night. Ray

your design impressed me that much, that I like to have one to. Unfortunately the link answers with: This link has been removed. Sorry, access to this document has been removed. Please contact the person who shared it with you. Living in Switzerland I tried with VPN too, but same result.

Hi Peter I just checked the link on my end and it works for me I didn’t know that there would be issues in other parts of the world you can email me and I will send you the files [e-mail] I will be looking into posting it on other servers Sorry about the inconvenience Ray

Very nice! Have you checked out Adam the machinists channel? He has some neat printed tools. Are you on Instagram? It’s a good place to share your work. (And how I found you)
