On the Woodworker the specs say (B) is 37 3/4"… I’d like to cut my board to the inside of the footer. Or where it flairs out on the bottom from side to side. Anyone have that measurement? Still have two months to wait but wanted to have the board ready. Thanks
You can make the wasteboard up to “36.299” inches wide like the drawing shows, but practically I think the biggest you want to make it is around 33 inches maximum. If you’re going to use a flattening bit, you’ll want to be sure the outer diameter of the flattening bit can reach the full width and depth of the wasteboard, otherwise you’ll have a little raised edge around the whole thing which might get in the way.
Of course, if you have a flattening bit larger than 1" (which is pretty typical for the Makita router’s capability) then you can go a bit wider. You may still wind up with slightly rounded raised corners at the four extreme points though, depending on how you set it up.
Good luck! Will be cool to see what you come up with!

The maximum cutting area of the ‘Woodworker’ machine is 32.125".
32.126 … 
Just rounding down to something you could easily measure without a micrometer.

Thanks for you information… One month to go for my 1F… Still up in the air on the wasteboard on what to do. If I can cut 32.125 it would be nice to have hold downs on each side using T-nuts to the width of 37 3/4"… I might not even need to use a flattening bit since the bench that contains another CNC machine is perfectly level. Now that brings me to the wasteboard not being completely level and I find that it does have dips or whatever in my projects, I can then use the leveler. Now I’m trying to wrap my head around what difference does it make if I only level to the 33". The 2 3/4" on each side would never be used except for hold downs. Thanks again, cold and rainy in Maine
your going to want a flattening bit. it becomes a maintenance tool. did in my case anyway. and it will help keep your waste board level with the machine. I’m moving to a T-track system Hybrid kind of thing.
Would be nice to have the measurements in the metric system too.
About 7 billion people use the metric system.
Anyone who can operate a CNC machine should be able to multiply by 2.54. Just like I’m capable of dividing by 2.54 when I need to. This is no big deal.

Hey Barry, hey Tom @Geige,
yes! 94% of world population want to do that all day long, that’s so much fun! While we’re at it, why don’t we use Fahrenheit unit from now on? It was created by the Danish Ole Rømer! And we know how much the U.S. citizen admire the Danish. Anyone can subtract 32 and multiply the result by 5/9! That’s so much fun!

PS: Of course I’m joking. Everyone knows how much they mourn the British Empire and that they are no longer part of it because of stupid independence. When the French had their revolution, they immediately disposed the King’s unit systems.

Barry,
I was just an asking Onefinity do deliver a great customer service by providing the metric values in their technical drawings too.
So you are basically calling me an idiot for not being able to do a conversion, why the hell did you answer at all if you had nothing better to contribute? I found most people helpful on this forum, do you think your answer provided any useful information?
@Geige
Tom am just a beginner at CnC’ing but this is what I did and would probably do the same thing when I replace my spoilboard.
Put a 1/4 inch steel dowel rod into the Makita and took the machine to X0 Y0 then tacked a T-track with the corner at Y-1mm X-- On the outer side of the dowel, then moved the machine to X0 Y500 and tacked the T track tight against the T track on the outside of the dowel then moving only the Y axis as I screwed the Ttrack down using the X0 to ensure straight and square, Then used the installed Ttrack as reference just put my spoilboard planks tight against the first Ttrack laying a plank then a Ttrack then a plank checking each new plank to be at Y0 along the X axis,
A suggestion do not bother with dog holes if you want them you can cut them in later. I suggest you install t nuts on the underside of the board because if you use MDF, threaded inserts will distort the bottom of the spoil board and if you tighten hold down bolts too far they will lift the spoil board,
Next time I put in a new spoil board I will drill holes in the plywood so that an overlong bolt will not bottom out and press on the plywood table and lift the spoilboard. With Ttrack on both edges of the cut area, the leveling bit will clear the Ttrack and not leave you any ridges, I also cut my planks to end at the max cutting area for the same reason. I ran the Ttrack wild on the back end so if ever I need a holddown out there in the wilderness I can use the tracks.
Lots of you tube videos I looked at many before designing mine
Cheers.
PS Almost all my 80+ years I worked in Imperial but when I started in to CNC I switched to MM, It does get a bit irritating when cuts move a little as the cad cam software I use converts from Imp to MM and gives rounding errors.
PPS was in England a few months ago and they weigh people in STONES.
I didn’t call you an idiot and I’m sure you capable of operating a CNC machine. I just think it’s a bit silly all the butthurt on social media and elsewhere about needing everything listed in metric units. That would be like me being upset that the fasteners are all metric, or that the dimensions of most of the China-sourced components are whole metric numbers (except for the NEMA stepper motors; it seems China has no issue working with both units). In the real world, especially in the region where the vast majority of Onefinity’s customers are located, both metric and U.S. Customary units are in common use. We’re only talking about a half-dozen numbers in the manual. I’d rather not have to have two sets of hand tools, either, but it is what it is.
You should re-do that map where each country is scaled to its GDP. 
BTW, I don’t think Celsius is any much superior to Fahrenheit. Setting zero in Celsius to 273.15 K (which is the official definition of the Celsius scale) seems just as arbitrary as setting zero to 255.372 K in Fahrenheit (Kelvin is the SI-defined international standard temperature scale). In normal life, I think Fahrenheit is preferred as the size of the degree is smaller.

If the US had stuck to its agreement with Canada to go Metric in 1980, you two would not be arguing.
In the mean time play nicely there is enough sturm & drang in the political world, without bringing it here.
Hey Barry,
I cannot agree. The unit Celsius is based on defining 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 atm pressure. That is a pretty good definition as the freezing and the boiling points of water at 1 atm are the same everywhere.
So if I look into my refrigerator at the various thermometers, I can see that vegetables in their compartment are alright around some 1–3 °C above being freezed (which would be 0 °C) and if I boil water, it reaches 100 °C when it boils, so I can put a thermometer in it and see when it cooled down by a desired amount, to make the tea (e.g. 80 °C).
So all I have to know is 0 °C is freezing, and 100 °C is boiling. Fahrenheit does not provide such a clearness.
Also the step from 0 K to 1 K is exactly the same as between 0 °C and 1 °C. Celsius is just shifted with respect to Kelvin, the SI unit. Fahrenheit does not offer this.
The other argument is the same as with the other SI units like meter, liter, or gramm: Look at all the blue countries in the map:
Image: Use of metric system in the world
Did you consider the fact that all these people, more than seven billions, once all had a different measurement system with different units. What they did, is to abandon it. Was that easy? Surely not. But they all did it. They all have the advantage of using units that are the same everywhere on the world. If everybody has a different measurement system, this leads to big problems. And this not only Mars Climate Orbiter, it is more that you want a weight, or a length, to be the same in the next town. That was not the case before the world agreed on a common measurement system, the SI units.
So what is about a single specific people that is not willing to take this step? If all the other 7 billions of people did it, even though THEY ALL had to abandon their old system?
Hey Barry,
Look: The metric system is what at least 96% of this planet’s population agreed on. You cannot ignore this. The problem is, when you see a number in a unit you are not familiar with, you do not have an impression of what size that is. Nearly nobody in the world at the first reading knows what 153" are, but at least 96% immediately have an impression of size when you write 3.86 m. Because they are used to a meter and not to an inch. The difference is, the first is what nearly the entire world agreed on, while the latter is something which nearly the entire world agreed to abandon it, so you can’t blame them for that. And you can’t compare. It is not the one or the other, it’s what the world agreed on, and the other is what world agreed on to abandon.
So when I tried to find out what CNC machine I should buy, I found the Onefinity and read that it has a 32″ × 32″ workarea, and I had to calculate what size that could be in order to be able to compare it with other CNC machines. So when I realized that the Onefinity Woodworker is a CNC machine with 80 × 80 cm workarea, and later the Journeyman came out with 120 × 80 cm, I found that great. The strange thing is, nearly nothing on this machine is imperial or U.S. customary. As it is made from parts from international market (mainly china), all bolts, ball screws etc. are metric. The Onefinity manufacturer has to first translate it to U.S. customary because they target the market in the specific single country on the world where ordinary people are not willing to do what 96% of the world population (or approx. 7 billion of people) already did in the past: To abandon their units system in favor of an agreement that (nearly the entire) world agreed on.
No problem:
Largest economies in the world by GDP (nominal) in USD trillions in 2023
according to International Monetary Fund estimates[n 1][1]
By the way, the European Union with 448 387 872 inhabitants has these values:
| GDP (PPP) | 2023 estimate |
|---|---|
| • Total | $25.399 trillion |
| • Per capita | $56 928 |
| GDP (nominal) | 2023 estimate |
| • Total | $17.818 trillion |
| • Per capita | $39 940 |
That is the case in no country of the world (except one). This is the one that on CNN rarely shows what happens in the world. Especially not on the first headline. Usually on the first headline they show only a man that was not taught how to make his hair. By the way, the UK had such a man too, nobody donated him a hairbrush, not even for the Queen’s funeral.
By the way, the topic belongs to this thread. Please further discuss the topic there.
Hey Tony,
the United States switched to metrics very early, much earlier than Canada. See here.
In the USA, metrication in legislation begins with the Metric Act of 1866. The first section is still part of US law (15 U.S.C. § 204). In 1875, the US became one of the original signatories of the Metre Convention. The US current law states that the metric sysem is the preferred system of weights and measures for United States trade and commerce (15 U.S.C. § 205b).
And metrication in the USA was a big success in science, military, medecine, manufacturing, etc… It seems that the people that don’t want to follow this step do mainly not belong to one of those sectors. One sector that practically did not follow is the construction sector. And the weather forecast.
You are right, I already mentioned that there is a thread in “Feature requests” where this discussion should belong.
By the way, the original poster of that thread and also Tom @Geige above did not ask to replace the U.S. Customary or Imperial units in the Onefinity technical drawings by metric units, but just to give the metric values additionally. So I cannot understand if people fear that someone is trying to take something away from them.

@Aiph5u When I bought my first CNC I decided to work in MM, what I like about it is that the basic unit I use is roughly 1/25 of an inch, I used to work to the nearest 1/16" with skill saw etc. The other thing I like is that adding, 5 & 3/8ths to 2 and 9/16ths is a drag, then converting to Decimal inches is even more of a drag. compared to 405mm plus 27mm which is a snap.
What I do not like is that Easel for example is written in Imperial and when you work in MM you get rounding drift which throws off things like dowel placements when you rotate a part in the software. Am told that Aspire has the same problem, which I hope is not true.
Using MM is a piece of cake, the biggest hassle is the occasional times one has to convert Imperial to MM, which seldom happens.
Edited to add is that working in Imperial is much more difficult, which does help to ward of Alzheimer’s.
