Precision O Ringing

After many tedious hours of machining, testing and tweaking the cylinder O Ringing tool I made, we did Adam's block which came out perfectly well. George made the grooves without a hiccup.

Many people complained that when their blocks were sent to be done at machine shops, the O Ring groove had a square finish at the bottom where the O Ring sat.
This is not good since the wire has room to move and will eventually sit lower on the block deck, reducing the clamping force between headgasket and the O Ring. This of course defeats the purpose of the O Ring making the gasket prone to failure again.

Regardsless what you use and how expensive it is, if its not properly done it WILL FAIL.
Not surprising, when we pulled Adams engine apart, his expensive MLS head gasket with what seemed to be Race Ware studs was blown three places!

This square bottom groove is unavoidable when a milling machine is used with an end mill to machine the O Ring groove.

The tool I designed and machined, cuts the O Ring groove to the exact same curvature of the O Ring wire used, so the O Ring fits tightly maintaining the exact clamping force between the head, head gasket and O Ring.

Two pics of the first two cylinders done.
