I think a \$90 shop vac is good enough.

By the way, the guy that wrote (pirated) the Ebook also thinks 1/4" = 1'-0" is the same as 1:50. There are only 48 quarter inches in a foot. So, the model to paper ratio of 1 paperspace unit = 50 modelspace units {1:50) is bogus. What you really get using 1:50, is 1 paperspace unit (1 inch) = 50 modelspace units or 50 inches, or 1/4" = 1'-6". Quite a difference. Throw the Ebook away. You got taken.

2. +1 Apparently you were sent the FBook.

3. 1:50 in metric is roughly equivalent to 1/4"=1'-0" in imperial. It is not assumed to be exactly equivalent.

Along the same lines, but speaking of paper sizes, a metric A4 sheet size of 297x210 is roughly equivalent to the imperial "A" sheet size of 8.5x11. The actual size of an A4 sheet in imperial units is 11.7"x8.3".

I always have a chuckle when those in the USA say they will never get used to metric, never adopt a metric system, imperial is always better, etc.

Come on guys - you use a metric system everyday.

Your money has been metric (decimal) at least since you started minting your own in 1792.

You don't seem to have any problem using that.

PS. Here in the UK we had an imperial monetary system until the 1970's (12 pennies to the shilling, 20 shillings to the pound, etc) then we changed to a decimal system.
So the USA had a metric system in everyday use long before the UK did.

5. 1 meter = 1000 mm = 100 cm = 10 dm
How hard can it be. xD

6. Hi ReMark,

Thank you for your help. With regards to the 11' x 17' instead of 11"x17" also makes it confusing. I took this snapshot verbatim from the ebook itself. Anyhow, thanks for noticing. The book is confusing in terms of giving dimensions in imperial since the book switches the symbols for feet & inches.

Kindly see the attachment regarding the book cover.

7. I have the 2009 version of that book on my shelf.

That's one of the reasons we were able to out evolve you to the point where we can drink cold beer.

No such thing as "roughly" in math. But then if you really want feet that are 33.333333% too big...

If you use 1:50 scale, as long as you label the drawing scale as 1:50 you're fine. If you label it 1/4" = 1'-0" not so good.

The way the book is written, especially that paragraph about 1/4" = 1'-0" (1:50) is so confusing that the writer may very well be correct in what he is saying, but there is no way to know by the way he states his point that he is exemplifying a comparison between the two scales rather than saying they are the same. It is written as if he is implying that the two scales are equal.

One can say quite correctly that 1:50 is the metric equivalent of 1/4" = 1'-0", but one must understand that equivalent means very close, but not quite the same.

I know how you feel. Even worse, just after I upgraded to a few hundred bucks worth of six point sockets (twice as strong as the hobbyist 12 point socket) for my air wrench, the really good bolts now come like THIS! arrgh.
