    I second Glen Dye. However, it's been around 20 years since he did some liners for me.

    I'd be very careful sending stuff to that individual, I had a hard time getting parts back from him years ago when he had them over a year.

    Had to send a registered letter threatening to sick a collection agency on him...

    Just a few questions........How will thy hone the tapper back in the liner and where will you get a piston with the right fit to put in it?
    Also how $$$$$$
    All this to bring a dead old eng back to life?
    Think it would be better to just spend the $$ and get a new up to date eng with parts available to rebuild.
    Just a thought.....................

    I could see rechroming and refitting the piston to an engine that's still run like the K&B red head outboards. I'm sorry to hear that about Glen. I spent a long time talking to him at a control line speed event. He was very knowledgeable, but that was a long time ago.

    Good thinking David!

    The re-chroming of any type of brass cylinder is a straightforward process. The existing hard industrial chrome plate can be easily removed in a 50% solution of warm HcL acid. However, removing the chrome plate from any type of aluminum cylinder can only be done by grinding the chrome off. All cylinders have the designed taper amount machined in the cylinder before any chroming or honing takes place. Pistons are easily fitted by machining various size pistons in .0001" steps. Accurate measurement of the taper amount & the roundness of the cylinder must be done "BEFORE" any piston fitting is done.

    Very few "engine builders" & machine shops have the necessary knowledge plus the equipment to accomplish what needs to be done!

    Dave, I'd like to get one of those Sunnen small cylinder hones with corkbond like Stu has.

    When I sent a Picco 80 and 90 to Millennium, we sent new pistons along with sleeves.

    They were familiar with taper, did it right, and left a nice oil retaining crosshatch.

    It seems to me I paid in the neighborhood of $85 for the two. That was back in latter

    80's. Worked great, ready to go, no break in required. I think they were better than

    OEM when they were done.

    When honing hard industrial chrome for a high silicon alloy aluminum piston, never use a "oil retaining crosshatch" pattern. It does nothing except increase the piston's wear. The correct taper in the cylinder & on the top edge of the piston will provide more than enough lubrication, even at RPM's well beyond 30,000.
