I am looking for a practical solution:
Given two, three (or more) holes on a small plate, in order to repeat the drilling on another one, I would like:
1) Measure the diameter of each one.
2) Measure the distance between each pair of holes.
3) What if the holes are not drilled on a flat plate?
Just for you to have an idea, imagine I want to mount a stepper on a frame and that the mounting holes of the stepper are NOT symetrical to each other.
My need is by NO means limited to the stepper case, so please consider a generic situation where two, three or more holes drilled in a plate and that the plate is NOT available as a "template".
I have no access to any equipment.
Could you also add some idea of how much precision I could obtain with whatever method is suggested?
Gracias for any help on this.
Hi, with "no access to any equipment"....whew that's a tough one.
The most agriculteral way would be to make a paper template of the bolt on area by placing a piece of paper on it and rubbing the holes onto the paper so making an impression of the hole centres.
Once you have an impression of the bolt face.....find the hole centres and make a cross on the paper with a pen or pencil.
Then use a centre punch to transfer the hole centres to the mounting face for the stepper, whatever.
You can get quite accurate if you get a good impression, and if the holes have a bit of clearance it will help.
Hope this helps, done lots of that kind of work in the past.
