polishing a piston ?

[ief]

in stead of (only) hohning a cylinder, would it also be ok if one poliched/ scrubbed a piston an then hohn the cylinder accordingly?
<BR>
<BR>what i mean is:
<BR>
<BR>making a piston wich is nit so good like new by polishing it, get some other cylinders and hohn them to fit the piston

If you hohn (!?) a cylinder its volume gets bigger; but if you polish a piston it will get smaller. Okay, normally only some mm^-1/2 but there's no sense.
<BR>
<BR>Take some cylinders to hohn (what's this in english correctly?) and after that let you build some new pistons fitting 100% to the cylinders.

hi ide,
<BR>
<BR>i understand all that BUT...
<BR>
<BR>the pistens i have are overbore, the cynders i'm talking about are original...
<BR>
<BR>so you see what i want ?
<BR>
<BR>ps:
<BR>guess hohning is just boring out or something <IMG SRC="/phpBB/images/smiles/icon_smile.gif">

So if the pistons are good just bore up (hohn) the cylinders until the pistons match with the cylinders.

<BR>I do not really understand what you want to tell us <IMG SRC="/phpBB/images/smiles/icon_frown.gif">

If the(oversize) pistons are scratched,you can carerfully polish the surface.Get the barrels rebored according to the correct clearence between piston and barrel.Get new piston rings and it will be ok.
<BR>But be shure not to use a piston more than about 40.000 km,the risk of damage will be very high.

hush, hush ide, easy does it <IMG SRC="/phpBB/images/smiles/icon_smile.gif">
<BR>
<BR>the pistons have litle "reifen" so that's why i thought of getting them polished, the question is, could that be done safely?
<BR>
<BR>and then, to get the cylinders the right messure i have to get them bored...
<BR>
<BR>maybe i'm just asking a to simple a question? <IMG SRC="/phpBB/images/smiles/icon_redface.gif">
