Honing cylinder bores at home

Postby cat007 » Tue Aug 12, 2014 2:39 pm

Hi

My cylinder bores are in pretty good nick. You can still see the cross hatching quite clearly, and they don't appear to be glazed.

Is it worth me just getting a honing tool and doing it myself with a drill?

Most machine shops that I've found aren't open in the weekends and I can't really get there during the week unless I take time off work.

Is there much of a difference between doing it at home or getting it done by a shop? Would they have some special tool, or would they be doing it just the same way?

Scratch this post

$60 to get it done by a machinist and I'll just take a couple of hours off work. I'm sure I have a 'client meeting' tomorrow....haha

If it just needs a quick hone then it should be a 5-10 minute job while you wait. It's pretty much just a stone in a drill run up and down the bore a few times.

Totally something you can do at home WITH THE RIGHT TOOL

SLOWLY in a drill

I prefer the 'ball brush' type of hone

The spring loaded 3 legged ones tend to put a taper in the bore if you aren't careful

But for a quick $60 you'd be better off getting a pro to do it if its a one-off type thing

Make sure you clean the bores VERY thoroughly afterwards - hot water and soap with a scrubbing brush - then dry thoroughly and lightly oil to prevent rust
