Cylinder honing

My method is to run a hardwood dowel in a powerdrill, and add some Brasso, gives a lovely finish, just keep moving the cylinder along the dowel so you don't get any high spots. It's cheap, and very cheerfull... just let go if it grabs.

What are you trying to achieve? Exact cylinder size or a cross hatch honing finish? If the former then any engine reconditioning shop with a conrod small end honing fixture will get you within a tenth of a thou. If a cross hatch then a bit of emery cloth in a split bar and move it up and down in a power drill at

The automotive tool supplier, Sykes Pickavant, sells small three stone hones for reconditioning hydraulic cylinders. I can't remember the smallest size but ask at your local motor factors.

You need to exercise a little caution with those, or else the spring-loading of the stones can cause rounding of the rim as the stones work in and out.

With that cauti> >Can anybody tell me the best way to hone a 5/8" cylinder. Does

Although 3 seems to be the natural magic number for the number of honing stones it's by no means essential.

For small bores, 1 stone hones are quite OK and much easier to manufacture. Delapena make single stone hones for bores as small as 1/8". The main body is a steel rod just less than 1/8" diameter with a longitudinal slot to carry the stone. Springs are not used but the hone is expanded by a steel wedge in the slot behind the stone.
