With K&S round tubing, I remember that the OD is always 1/32" larger than its ID. This works for brass & aluminum, I'm not sure how their stainless runs.
Dr. Fabio, yes, that's a good trick with the front axle tubing. I first saw that being done on brass/wire chassis in the early 70's. Drill a small hole or make a short slit on both ends of the front axle tube. Either will make lubricating the front axle much easier.
