Bryanj:
Maybe i'm too cautious but a proper hone can take several thou out and as the piston/bore clearance is very tight plus reusing old pistons its just me thinking it might take too much whereas the flapwheel will simply remove glaze, i used to rebuild essex, kent and pinto engines very regularly for a lead footed mate and only ever used the "glaze busters" about at the time which were basicaly long shanked flap wheels

the few times that I have changed rings I have used a 3-legged grinding wheel like the one in the photo and I have gently scratched the surface with oil, I will see how it looks with the dry-mounted sandpaper, I have taken the precaution of buying a finer grit (150 ) I'll show you how it looks, I haven't bought the rings yet, I don't know whether to buy the 4 INTO 1 or the IMD ones, they are made of different materials

murdock:
anyone has experience with any of these rings?
Trigger:
It doesn't matter what rings you use, if the piston to bore clearance is out of spec, the engine will smoke ;) And if you have honed it, it will be out and new rings would not work .

I'll be working on my engine probably next winter so I want to prepare myself ;)

I used a tool like that in the late 1970's on an A series engine - the bores were brilliant afterwards - trouble was it would only tow start afterwards so had to take the engine out again to getr it rebored! Never touched a glaze breaker since!
