Hi R.
The only annoyance was the +5 was missing from the box
The way they are made to be used is, the bushes when made should be 10 thou under 1/2 inch.
The short cut end of the reamer is also 10 thou under size. So it will go through the top bush and into the bottom bush and work as a parallel guide as the middle cutter cuts the top bush to 1/2 inch.
Then turn it upside down, the middle cutter will work as a guide in the top bush. As the end cutter will cut the bottom bush.
The importance of all this, is you are guiding the reamer to the centre of the hole in the bush. Everything is parallel.
If you use a standard or taper reamer, you cant judge the two holes are cutting perfectly in line.
With guesswork, you have to do something dodge at the end of the job to stop the kingpins from being tight.
That's why companies make the right tool for the job
