Default measuring axle alignment

i just mounted my landing gear and are a little unclear on how to check on axle alignment . i put a block of wood on each axle and ran a string between them.

I’m not sure if the 12is exactly the same as the 14 but sounds like it might be. There is a good explanation in the 14 plans on how to determine toe in/ out using the wood blocks and string. If the 12 plans lack this detail take a look at the 14 landing gear chapter. Essentially you measure the gap between the string and block and from this calculate the angle.

Those cheap laser levels that shoot a beam of red light are handy, too. You can drop a plumb bob from...say...the tail and project a red laser line on the floor to measure the alignment of the axles or wheels.
