OK so I've got myself one of those 3 legged cylinder honing jobbies to do my megane block with.
I'm a little nervous about the whole thing to be honest, I can see that I could do a lot of damage and potentially render the bores useless if I fuck it up.
So, anyone used one and know what the deal is?
I know you have to use it very slowly, so I'll use a battery drill. Obviously I'll try to use it in such a way that the result mimics the criss cross honing lines already present. Also I'll use a lot of lubricant obviously.
Other than that, any tips? How long should I do it for, just until it's got a constant finish all the way up the bore? |

main problem is people go at it for to long, they forget it increases the bore.
go up and down only a few times and see how it looks. |

i HATE hand glaze breaking or honing.....its probably step one to a bad build.
Honing and glaze breaking, the number one thing is to keep the bore straight and zero taper.
Second is the grit and honing pressure you use.
And lastly is that you need a bathtub of honing fluid flushing through in massive amounts.
A hedgehog or a tripod wont do this, you cant keep it straight, you cant regulate speed and motion, you cant adjust pressure properly....its wank.
And a new one, the stones will be sharp as anything, if you must use it, break it in on an old block.
The hone is essential to making power, it makes of breaks and engine no matter what else is going on.
And that is why i pay stupid money for a block turnaround that take over a week. |

If you have a spare block, pactice on it and break in the hone tool.
What grit is your tool?
Just dont forget that it will need constant flushing with honing fluid, have someone with a bucket and a bathtub.
If you use a machine shop, dont use them if they have the same drill attatchment.
I prefer a sunnen CV-616 or CK 21.
Old skool donkey heads are ok IF the operator is good. |
