## Abstract

A circular hydraulic press reforms and resizes a chamber opening in a combustion chamber housing. The press comprises a bar having a U-shaped end and a pair of free ends. The press comprises a panel having a C-shaped edge, a mounting edge, and a pair of slotted edges. The U-shaped end of the bar and the C-shaped edge of the panel buttress the perimeter of the chamber opening. The slotted edges and a pair of tubes on the slotted edges slidably receive the free ends of the bar to enable displacement of the panel towards the bar. A disk having a predetermined annular shape and circumference positions in the chamber opening. A hydraulic piston displaces the C-shaped edge of the panel towards the U-shaped end of the bar to press the chamber opening against the disk, and thereby reform the disk to substantially the same shape and circumference as the disk.

## Claims

at least one force adjustment member configured to increase and decrease the unidirectional force in conjunction with, or independently of the pump,
whereby the unidirectional force moves the C-shaped edge of the panel towards the U-shaped end of the bar,
whereby the unidirectional force presses the C-shaped edge of the panel and the U-shaped end of the bar against the disk.

### Claim 2 (depends on 1)
