1/16" = 1.6 mm = .062"

1/8" = 3.2mm = .125"
1/4" = 6.5mm = .25"
as you can see, its simple, but its not critical, a 1/32 is so small in the big picture, if you are worried about it just redimension the drawing in numbers you will understand then forget the rest,
now work out the specific gravity of the tubes and add the mig wire and you will know the weight of the chassis and the point that your table will buckle under the strain!
Yea, I can convert decimal inches into a fractional inches, that wasn't really my issue.. it was more just wondering what you guys were doing, reading the book dimensions, and them not being typical fractional inches (ie x.9 = x - 14.4/16ths). But, you're right, 1/32 is such a small issue that as long as I'm close, I should be good. So like I said before, just gonna go to the nearest 16th/32nd and be done with it!

i built my car using cubits as the standard measurment,
you could try rods, poles or purches
before they built gallions they would make a standard stick to which all the shipwrights would work.
its not rocket science, if you are off by 1/8" when the chassis is fully welded, you will be one of the lucky ones.
Hahaha, I'm just gonna use my finger, forearm, and thumb width to measure the rest of this thing, no big deal!

For those not fluent in conversion of decimal inches to fractions, just Google decimal to fraction. There are many versions of these table, some including metric. Pick your favorite chart and print it out. Put it up near your workbench of wherever.
It is more impportant that the two sides of the chassis end up the same length (within say 1/4") than the absolute length of the chassis is perfect.
Good point. As long as I cut the opposite side tube the exact same, it won't matter all that much. I've got myself a calculator, and know many conversions by heart.. but I might print out one of these charts just to make it even quicker. I'm sure after a day or two of measuring/cutting/drawing i'll know every fractional equivalent there is to know by heart!

Someone had mentioned this yesterday.. about the sawhorses getting wobbly.. here is a pic of the arms extended. For now, this thing is like a rock.
And one of the newest work space... not a ton of room around the table, but definitely enough to get myself around without too many issues. Gotta push the snowblower out each time, but luckily.. haven't had too much snow (read.. almost none), so haven't had to use it!
