case boring?

The cases are split, and set up in a vertical mill, on a 90* precision angle plate, machined just for that application, square with the quill, and indicated dead nuts on center.
If using an Axtell 4 1/8" cylinder, a 2 step boring process then is established, and the dimensions are held to their exact specs.
Once that is completed, the center hole is then machined thru to the lifter side, and their proprietary hardware is then used.
Usually what follows that, is also a Timken bearing conversion in the left case half, as long as the crank is running true.

We have been boring cases for over 20 years.
The cases are split, and set up in a vertical mill, square with the quill, and indicated dead nuts on center.

Boring Job
Remove and disassemble engine.
Gut the block and reassemble the 2 halves.
Mount in milling machine, level, and center on the case bore.
Chuck up proper tooling, cut to desired diameter.
And as mentioned, a second step cut is done where necessary.
A twin cam A block goes like this.
