apples and oranges. The problem is accurately measuring a fraction of 1 degree variance over 15 inches, against a string that is probably as thick as the variance we are trying to measure.
Don't take my word for it, though... Go to |3827 Jefferson Avenue in Midland, Michigan, and check the |straightness/verticality of the cinderblock basement walls for yourself. |Strings, plumb bob, and tape were the only equipment (other than a |level, a bricklayer's trowel, and the gear needed to mix the mud) used |to lay up that foundation. As a bonus, Marty either refused, or couldn't |afford, not sure which, to buy/rent a transit to shoot the site to place |the foundation. So three pieces of string set that house up so close to |perfectly square in relation to the invisible (at time of construction, |anyway - dunno if the landscapers cleared a view to it or not) road that |I had a hard time believing it even though I stood there watching it |happen. I still don't claim to understand *HOW* he did it, but the |results speak for themselves...
I just read "Working Alone" (Or something close to that) about how to lay out construction projects - foundations, walls etc - with just string and lumber, a plumb bob and a pocket calculator. Anything more is a convenience.
| |> You buy a camber gauge for $40-$50 | |I guess there's that method, too... But in the context of the discussion |(low tech ways to fiddle with alignment) it seems *JUST A LITTLE BIT* |like cheating :)
The only way I know is to use a large square, laid on the end of a straightedge spanning the tops of the wheels, with the 90-degree leg sticking down besdie the wheel. Then you measure top and bottom to edge of wheel, apply trig. Oh yeah - only works on open wheel cars.
