16mm test bushing set.
by xochal, published
this is a set of test bushing to figure out what size you should size your holes to make a 8mm brass self aligning bushing fit properly.
I designed it so someone else could tell me what size i should make the holes when i modify my x carriage for brass bushings. (i dont have any on hand)
the test bushings have the actual size printed on them.
UPDATE: 2/4/13 to clarify the marked size is the inside hole size.
I suspect that the porper size should be about 16.2mm you can print the whole set as a plate or one at a time till you find the proper one.
