Title: Veco pistons
Post by: Russell Shaffer on August 06, 2007, 08:19:27 PM

I have seen ways to "grow" a Fox, McCoy, etc piston.  Can anything be done with an old Veco 45?  I don't even know what that piston is made of, but mine could stand a little more compression.  Any suggestions will be appreciated.  Thanks.

Hi Russel. This may seem a little mid-eval but I've had good luck on othe steel pistons using this technique. I take the piston (no pin) and balance it on an aluminum bar. I put about 6oz of 10w30 in a soup can. I then take a torch and heat the piston carefully untill it becomes deep red all over. I then quench it in the oil. It should grow. I have revived quite a few engines this way.

Hi Dave,

That sounds better than the "oven method". y1
