i'm about to rebuild my engine, i already ordered new rings, crank and rod bearings.
the question is.. what's your/best way to deglaze cylinders?
can i use a certain grit of sandpaper to do the job, or should i get a honing tool to use in a drill?
cheers

no! you need to use a glaze breaking tool and a speed controllable drill on nice and slow. Don't go anywhere near it with sandpaper :)
Assuming you've already got a suitable drill, glaze breaking/honing tools aren't expensive.
Go easy on it, you want to take out the smallest amount of metal possible.
thanks for your reply hayesey!
gonna get a hone tool. which one you think to the the best, that 3 stone type hone, or that ball brush?
well I used a 3 stone one because I just borrowed it off a friend. Apparently those bottle brush type ones are meant to be easier to use for someone who's not done the job before.
have a read in any old haynes manual - I think there is a section on using a honing tool IIRC. There is an ideal sort of speed & angle to leave the hones marks at (could be around 20°? It's in the book) and you want to get that right too.
yeah and dont let the honing tool stop in the bores either or it'll make irregular grooves while it slows down, keep the speed slow and steady, moving up & down steadily too (el oh el :D ). And when you are ready to pull out (el oh el again :D ), keep the drill speed steady until the stones are completely out of the bores.
I'm sure there'll be several how-to guides on t'internet you can find using Google.
