I'm building a machine from a plan and it states numerous times that a hole should be drilled and then reamed out. It seems to be for two different reasons. The first is to make a snug fit for bolts. For example, a 1/4" bolt has a 1/4" hole drilled, and then a .251 hole reamed out. Another example is an injection rod having it's hole reamed out to .501, when the rod is 1/2".
A) I'm having trouble finding chucking reamers in these specific sizes.
B) The one's I've found haven't been cheap.
C) I find it hard to believe that each hole, to a thousandth of an inch, needs a seperate reamer.
Can a boring head do it? Can an adjustable reamer work (Harbor Freight has them, are they good? Do they work? Are they worth the money?)
As always, any comments appreciated. Thanks,
