quick question, you must always hone the cylinders? and if so is there any way of doing it yourself with out with out the tool? like 400 grit paper or something.

i had just recieved my parts and was hoping to put it back together for the weekend break'in. if not i'll just drop them off to get them done.

 

thanks

I'm sure you could do it with sand paper, but do you want to.  The honers are cheap, I think you can even rent one.  It's not worth it to me to even try to half ass it.

Yeah, if you even think about using sandpaper...you might was well get die grinder out. You have about the same chance as getting it even...:)

 

BB or stone hones are cheap...stone are the way to go...however, since BB hones like to snag on the ports....

Have them honed, a honed cylinder has a "cross hatch" to seat the rings, it should be a certin grit and the hatch has to have a specific angle, I wouldnt recomend doing it yourself you may taper it or remove to much material.

I've senn it a hundred times ( I work in an engine machine shop), and it costs more to fix!

You didn't mention bore in your first post, you just said you received your cylinders.

 

If they were freshly bored by a shop, I agree...they should've honed them too.

You should have a nice, 30 degree hone on them, in a cross hatch pattern....

It sounds like you are convinced to pay the money and get it done right. One thing the honing tool does that sand paper doesn't is hone it out round. If you try to do it with sand paper by hand, it will be impossible or should I say extremely hard to get the cylinders pefectly round like they are suposed to be. if it is sand too much in one area the rings wont seat right and will fail prematurely. Just my .02......... :cheers:

normally you don't set up a whole machine to bore a jug .020 you just hone it out with "rughing stones" let them cool and finish them with the finer stone, lot less time. Remember you'll want 2-3 thou clearence if your running a forged piston.

If the machine is already set up for it, its not a big deal. Can be done in just a few minutes and with much better results than with a honing stone. I've seen it done too, I've done it myself but not that often.

 

I would have to agree with anyone that grabbed their face and gasped "OH NO, NOT SAND PAPER!". You'll NEVER (no 'extremely difficult") achieve a 30 degree cross-hatch with sand paper. This cross-hatch grain is vital to proper ring lube. Without it..might was well buy your rings in bulk and put 'quick-disconnects' in your cylinders instead of studs. You can hone them yourself with a decent drill. Rent the hone and buy/rent stones (not sure if you can 'rent' stones) and get yourself a quart of machining oil. I'd give you directions on the exact way to do it but I dont remember the correct way of determining the rpm and stroke of the drill.....don't want to get you all screwed up. Ask someone, its not a difficult task.

 

If you decide to have a shop do it, I know its relatively cheap. A friend of mine does it in his shop for (I am not 100% sure on this) about $7-8 a hole, boring for $35 w/ honing included.
