There are three types of tools: cheap Chinese, expensive Swiss (or other) and self made. The last is of course the best. You have totally opened my eyes when it comes to self made tooling. As a beginner, there is so many things on my wish list with regards to tools, and at the same time I am in need of projects. What better projects than to make your own tools? I have followed you for some time now Stefan, and almost every one of your videos is a build project for a great tool. Some might be a bit advanced for a beginner, but many are great learning projects. I just made your "better threading gage" from way back, and its my first "real" project where I actually make something useful. Thanks for all your great videos Stefan, you are a great inspiration to me an probably many others. BTW.

Great work Stefan, Just an idea: could the bumper not alternatively be made in the lathe together with stand and column - already mounted. That should always give You the perfect radius in reference to the column.

Thats right, I think Chuck/Outsidescrewball has done it that way. But the radius of the bumper does not need to match the distance to the column :)

Oh yes, You're right - my bad. Thinking about it again, I see that You need a unique reference point, but the bumper does not necessarily have to follow the radius of the column. A smaller "nose" would do as well.
@janspoerri64027 жыл бұрын
It is not as critical as I also first thought when seeking a minimum distance while making a sweep, but I assume it is good practice to have the indicator as perpendicular to the work as possible to remove lateral forces/friction, etc. Having an identical curve on the bumper would assure that. I wonder how much of an error that might cause in practice.

Hello Stefan, I'm thinking about making a surface gauge & squareness comparator and going over various designs I can find online. I was wondering if there are specific advantages to having the flexure / fine adjust in the base (e.g. Hermann Schmidt MG-1) vs having it on the dial indicator clamp like yours. I managed to find an archive of your linked blog post, might be helpful to starters like me if the link was active on your site. I can't seem to find the old blog posts on your new wiki. Thanks for making these videos, hope you had a wonderful Christmas. Happy 2023.

@MrMojolinux6 жыл бұрын
Yes, I lightly super glued a 1" Ball Bearing into the "V" of my Starrett Surface Gage (I can always knock it off if required) for the same effect as a machined radius at the base like Stefan`s. All you really need is a single point of contact with any radius, the zero`d indicator and the part to be checked. The advantage of Stefan`s self made Squareness Comparator over your typical Surface Gage is his fine adjustment design, which is far superior to any fine adjustment provided on a surface gage.
@GarethJefferson7 жыл бұрын
As usual, Stefan puts his engineering prowess on display for all to marvel at. I certainly did. However, I don't understand the purpose of the round buffer squareness comparators always have at the front. If the vertical bar that supports the dial indicator were to be mounted in an accurately ground steel or granite block with a straight, square front *without* a rounded buffer, why wouldn't that work? I'm clearly missing something fundamental about the math here. I understand that even a ball bearing would do the job, albeit a bit less conveniently. Can anyone explain the necessity for the round front bumper?
@StefanGotteswinter7 жыл бұрын
Oh a flat front would totaly work, but it would average out the surface if the vertical surface of the part was not perfectly flat. Sometimes you want that, sometimes you dont want that. A ball bearing ball would work too, but the small radius results in a very small anglechange to find the highspot - It feels more precise (and probably is), when the radius is bigger and you have a larger angle to sweep..
