Hole spacing .THE ANSWER

[VW mick]

Did try and start this thread before .

But no one really got into it ,what I wanted to know was the relation between a horizontal domino and a vertical domino slot
When using them as dogs and clamping slots

But I've Sussed it and guess what they work on 32mm centres .

Is that luck or did festool work that out ,?

I'd say Festool figured all that out.

Hence the LR32mm hole guide rails.

It is by design. You'll find a lot of our tools incorporate 32mm increments.  [wink]

So, I gotta ask..

Do you know why the standard (not just with Festool) settled on 32mm instead of, lets say 30, or 35 and so on. Silly question I know.

Cheers,

Peter, I could be wrong, but I seem to remember something like that was just the dimension used by hole boring machines back in the mid-1900s. I don't think there's a particular reason, just chance.

Seem to recall 32mm was adopted as the standard after WWII when the whole frameless/euro cabinet style was developed??

I seem to remember a post by ccarolladams that went into the history of the 32mm hole spacing and what drove it.  If I recall correctly it had to do with the task of re-building much of European housing efficiently after WWII, but I don't remember the details.

edit: looks like Richard posted as I was typing.

Ok I do seem to remember something about a euro standard after ww2

But but do you think they was thinking about using a domino slot as a dog hole and the dims of a festool clamp on an angle

Not shure but it works .. Handy info for any of you guys building a MFWB

OK, I feel super dense here... what relationship are we looking at?

Just the relashonship between a horizontal domino slot and a verticle domino slot for clamping

Will post some pictures of finished bench soon

Don't feel bad. I'm not sure I understood the whole thread. Maybe still don't.

I don't understand how the 32mm standard is related to the pictures at the beginning of the thread. On the domino the horizontal distance between the pin and the center of the mortise is 37mm. The vertical distance between the center of the mortise and bottom of the tool is 10mm. The mortises in the photos could be spaced at any distance.

This might help

Was just amazed that this worked

VW Mick, what you're showing looks to me as completely arbitrary. I don't see a relation between the 2 holes. How exactly did you come to place them as they are?

As for the 32 mm system, not sure if it's the full reason, but a lot of measurements in engineering are based on the binary system. The number 32 is part of that system, namely 2 to the power of 5.

2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256

In engineering, just as in computer science you will find these numbers over and over again. Using the binary system is very usefull when working with machines as it simplifies a lot

I've been on about this for ages no one seems to understand me lol (storey of my life )

Give me a couple of more weeks and all will become clear

You're right Shane, 32mm was the closest multiple that the spindles of the multi-head hole boring equipment could be adjusted to.

Others are also right that the 32mm System was introduced in response to post-War shortages of wood combined with the need to rebuild countries.

I understood the 32mm concept; just not what you were using it for and how the Dominos figured in.

 

[gkaiseril]

The stop pins are 50, 37, and 20 mm from the center of the center of mortise slot. I do not think that is part of the 32mm system. Although one could space them at 32mm on center of so inclined.

The 32mm spacing is for the 5mm shelf pins and the heights and widths in multiples of 32mm.

This was a European industry decision after World War II so all cabinets could easily be planned for in blueprint and for replacement with standard or nearly standard sizes. Since so much of Europe was destroyed or damaged from France to Russia and Italy to the North Sea there was a lot of hosing and offices that needed to be rebuilt as quickly and efficiently as possible. With all manufacturers using the same basic sizes it was easy to obtain cabinets from different manufacturers and install them at one location or many locations and not having to worry if they would fit or they could easily be fitted into a single unit.

Two threads to which CCarrollAdams replied provide insight into the reasoning behind the 32mm system; first and second.  Dr. Adams was there when it all went down, and has massive insight into the situation.
