This was inspired by Oxtools and NYC CNC. A 12" Rahn RoR is useless on my 18x24 surface plate. To answer some ?s, the feet will affect measurement if they do not fully contact the test surface. Hinge arm effective length is from pivot to surface contact, you can extend this by lengthening the arm and moving the pivots for less angular error. Stan has a very good surface plate, mine look more like an XGame skateboard park. Thx for the comments, criticism often makes a better design (more brains are better than one). Except for a 0.0001 dial indicator, this was built from rems. Cheers, Mike at Catalina Racing

Thanks Mike & Stan for sharing! This inspired me to try something along your lines, and my crude efforts at this is explained here: www.homemadetools.net/forum/repeat-reading-gage-diyswedes-cheap-o-meter-73022#post134042 Cheers, DIYSwede

Thats a tidy little design. Nothing quite like a dedicated tool for the job to save all that messing with a marking gauge / scribing block n dti. Thanks for uploading and sharing Stan.

I noticed the label says "refrigerate" how important is that?
@ROBRENZ6 жыл бұрын
I keep mine in the fridge all the time. It seems to last longer that way.

I also keep my CA in the fridge it helps a lot on the preservation.

Thanks for sharing that, and thanks to your buddy at Catalina. It's fascinating to see what other people build for tooling, and this little unit seems to work well!

That is an EXCELLENT tool! Thanks for sharing. It is now on my bucket list and by the way thanks for the plans. I have an old surface plate 36" square by 4" thick that I know is out of calibration, I will soon be able to address that to get it close to a true surface. Adequate for my needs I would think. Thanks again, Cheers from John, Australia.

Great! Now we just need the poor man's autocollimator, and the skills to properly use and interpret both tools...

Not as fancy as John's but certainly seems effective and a simple solution. I like it!

Big thanks to Stan for finishing the mini RoM. Had suggested surface grinding the feet, but Stan using a large diamond lap. Dummy me, had a big diamond lap in the kitchen and never though about using it.

Hello thank you for your helpful videos. Ihave one qoetion: Its not important if the carbide peaces that you leted on the bottom be different size? Best regards sina
@glenking33374 жыл бұрын
So, if where the knob on the top is. If that were changed out to a second dial indicator and could from there reach thru a hole to zero on the surface plate. Couldn't you zero two spots at the same? time?
@waynegotthardt32336 жыл бұрын
What are we measuring? The irregularity of the surface under the Carbide Feet or the surface under the Indicator Tip
@ShadonHKW6 жыл бұрын
Under the indicator.
@catalinaracing38super516 жыл бұрын
The 3 carbide feet form a ref plane. If you zero the indicator on your plate, any indicated deviation when sweeping the plate is referenced from that plane/location. This device finds wear spots and can be used to profile your surface plate with some accuracy. I have a -0.00045" deep trough where a height indicator must have lived for a long time. Gave a RoM to a friend with a AA plate with certs, he thought the RoM didn't work til he over swept the edge. This device is handy when buying a used surface plate, might get the price down if you can live with an A plate.

Just wondering how important is the distance from the pivot to the indicator on one of those?
@thomasutley6 жыл бұрын
Old Iron Shops Good question. My intuition says the vertical displacement of the indicator will be whatever it is, meaning however far the front point is out of the plane formed by the back three feet. If I’m correct in that assumption, then the swing arm radius only determines where you’re measuring relative to the location of the base feet and it can be whatever you like.
