Title: How do I lap a cylinder?
Post by: ian_in_the_midlands on October 22, 2014, 03:44:52 PM

I am going to have a go at making a flame licker engine, and like the look of the Poppin.
After teaching myself how to work harden stainless  :doh:, I am going to try again with some cast iron.

Many plans and descriptions of building these engines talk of lapping the cylinder for a good fit, but I can find any details of the process.
Are there any web sites with good instructions on how to do this, preferably with some pictures, or video?
Failing that, anyone kind enough to put together a tutorial?

Some good information there.
I have nearly finished the cylinder for my flame licker, but plan to let it stand for a few weeks to allow any movement.
That will give me time to make one of those laps.
Thanks.
