Bottle Honing and Break in Oil
« on: October 13 2018, 10:37:26 PM »
I have heard a jillion times that bottle hones were useless and I have seen them used more than once by some good engine builders

Most of the problems I have seen with honing came from trying to remove too much metal with the hone which resulted in burnishing the surface.  I suspect other problems came from failure to clean the cylinders well enuf after the process but no one ever admitted to that :D

A lot of broken parts does not make you a racer; it makes you a slow learner.

I've used em on more than one.

 That Malibu that locked up got a berry ball hone and a new set of rings and had 150psi in all the cylinders when it was back together. Then the bottom end went to knocking but that wasn't the hones fault.


 i think as long as they are relatively round you give em a cross hatch, some new rings gapped to the cylinder and run it on a budget.

I wonder is people will still be talking about those stupid crosshatches 100 years from now.


With moly faced rings, I like my cylinders to look like a mirror.   All a bunch of angled scratches are good for are letting oil into the cylinder and blowby into the oil pan.




Funny story. When I was racing out of a bike shop in Auburn, I met a couple of Brits that came over here to open a cylinder repair business.  They specialized in re-nikasil plating aluminum cylinders.  After starting up they started to get complaints because there were no crosshatches (and the plating is so tough, you can't do it by hand).
They had to go spend over $50,000US in machinery so they could mess up a damn near perfect finish just to make the customer happy.    I always had to remember to tell them not to scratch up my shit when I had cylinders replated.


They also used the phrase ''bedding in'' instead of ''breaking in''.  I was fun to watch them cringe at the mental image of how crude it is to ''break' in a brand new build.

Not sure what I put in for rings. Got em off eBay for the ford that had the similar dimensions.

I haven't read this entire thread.
Are you guys talking about re-ring jobs or are you still dealing with machine shops selling cross hatch cyl wall honing?

'Plateau' finished cylinder walls are well into their 2nd decade, or not?
Anyway, the desirable 'cross hatch' was necessary and mirror like when compared to its predecessor. This lasted somewhere around 40yrs.

The 'big boys' have left me some time ago, again. Hellfire rings and specialty coated liners are here.
