VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Deglazing

I thought deglazing the cylinders would have already have been discussed here, but the search says no. After straining Google until it cried, and I must admit, there is a mixed opinion, I think I will be better off with a Flex-hone to deglaze. Naturally there is a but, there is always a BUT ... I cannot determine the correct size Flex-hone, 3 1/4 or 3 1/2, or if there is a better size. My pistons show that they are 20 over, so the cylinders are slightly bigger than stock. What size Flex-hone (or alternative method) do you folks recommend?

The cylinder hone I have has springs on the arms and can be used on a wide variety of bore sizes. I would guess from 3" to over 4". Since the '29-'32 have a 3 5/16" bore I would think that the 3 1/4" surely would work. Guess the 3 1/2" would also. The hone I have seems to fit a much wider bore diameter. Seems to do a fine job whenever I use it. I think the key is to move it up and down in a regular pattern so you get more of a crosshatch then spiral pattern. At least that is what I was taught.

The flex-hone is a hone with little wires with balls of grit on the ends and would have a small range of coverage.If the cylinder size is between brush sizes the next larger size is used. For a 3 5/16 bore you would use the 3 1/2" hone.
A conventional 3 stone hone is less expensive and will also do a good job.

As always, good information is right here. I will use the spring arm hone. Sure glad I asked for your thoughts.
