Divider tool

Hi - this (from "Instructables" 11-point Divider), looks like a useful gadget.

Does anyone know if a version is commercially available? At a reasonable price?
Thanks,

Despite seeming to have so many points - I would say that it is entirely pointless. Don't waste your money or time on it.

If I want to divide something into several equal parts I just use my long steel rule and lay at an angle so the rule is measuring something easily divisible by the number I want and make a mark. Extend these marks to the edge with a square. Easier to do than describe.

I'd agree with that unless you're marking loads and loads of identical pieces. Ruler and mental arithmetic

Ruler and mental arithmetic

That woud work.
Or a slanted ruler as porker says.
Or, my usual approach, a pair of dividers. The clue is in the name.

Except in this case they multiply - if you set them up with a slight error, you will end up with a large error at the end of the run. The multipoint divider and the sloping rule avoid that problem.

That's true, there is a bit of trial and error involved.it is still the way I tend to work though. I am no stranger to trial and - especially - error.

These "lazy tong" type mechanisms require surprisingly good pivot points if the acculumulated slop is not going to be a problem. A bit like those pantograph mechanisms for enlarging / reducing drawings.

 

[GrahamRounce]

Yes, but so many times I've wanted eg 15.5mm into 6 parts, so had to work out a table: 2.6, 5.2, 7.8, 10.3, 12.9, 15.5 - a boring chore, after a while very boring! You can't always use a ruler at an angle, eg on a long thin thing.
I thought a precision-ish version, out of stainless steel, yes like a pantograph, could be useful sometimes.

Five minutes with a spreadsheet could create a re-usable template to feed in the length divided by number of parts required and then multiply the result progressively for each position measurement (i.e 1 x ?, 2 x ?, 3 x ? etc)

Got a version of this, won't be replacing it.

why not just use a simple divider? you don't even have to think of numbers and calculations, just set it up to divide in 6 parts, run it along the wood, no maths needed.

For those who can do a bit of CAD, design a bespoke scale, print it off and take it to the workshop
