| * Straight reamers are by far the least expensive to buy. It also makes holes that aren't true cylinders. \\ They can have a lobed wall shape. This lobing goes hand in hand with amount of material being reamed away. \\ In our case it's a small amount of removal so the lobing is also very small. \\ For us it's ok for pinion & #2. But a spiral is nicer albeit usually 2X the cost. \\ It's also fine for 1-3-4 if bushes have no oil groove in bore. \\ Grooves in bore need the gap bridging action that spirals provide. \\ This is where you need spirals. | * Straight reamers are by far the least expensive to buy.

| * Forward Spiral reamers will give a truer (but not perfect) cylinder. \\ Forwards gives the lowest cutting forces = easiest to hand ream with. \\ But they can 'grab' into the work (like a drill sometimes does). | * Forward Spiral reamers will give a truer (but not perfect) cylinder. \\ Forwards gives the lowest cutting forces = easiest to hand ream with. \\ But they can 'grab' into the work (like a drill sometimes does). | ||
