Hi

A bit of an off topic question but has anyone any experience of these bore honing/deglazing tools?

http://www.brushresearch.com/flex-hone.php

or a good recommendation for a tool for deglazing and slightly honing a good set of bores that just need new rings. This is in a golf with the crank in place.

Thanks

I did use them ,and they work almost like the 3 legged one's.
The result is the same ,although i prefer the 3 legged one because you can give it more pressure on the stone's.
I use a thinner or something like that to get better result.

I've used them a lot. In my opinion, no difference on a bore that is usable. If the bore is in bad shape, these will not show where the bore has gone bad. The three leg ones, having straight abrasive stones will show if there is a ring ridge or other discrepancies in roundness.

If the bore is in good shape, and just needs a deglaze, nothing works like a piece of red 3M Scotch pad wrapped around a 3-legged honing tool. I've had a number of high-end engine builders tell me that is their favorite method for bore prep to ensure good ring seating.

I always use a flex hone in the bores after finish honing to provide a finish for the rings to bed in to .

If your bores are worn honing them bigger to clean up is a waist of time , it just gives you a smokey engine .

Thanks guys,

The bores look good with minimum damage. They are glazed and there is a step of glaze where the pistons reach TDC. I would leave them as they are and just do the top end but I am told that the oil control rings often go on golfs if you just do this.

As stated above, if the bore is straight, without ridges or major flaws the dingle-berry hones shown on the front web page of the link work fine. If the bore has ridges or other problems, the dingle-berries can hide those from you where a 3-leg hone will highlight the problem areas.
