Piston Fixture Vises  - Piston Lightening, Piston Balancing

The ABS 5090 Piston Vise is a very versatile tool. It is obviously for flycutting valve pockets in pistons, but we here at ABS do a few more things. We use a three jaw chuck mounted on a double sine plate. This gives us a multi-purpose tool with two major advantages. The first one is that we aren't distorting the piston by squeezing on the pin bosses. The second one is that not only can we work on the top of the piston but we can turn the piston upside down and, using our T-5080 or T-6080 Pin Boss Cutters, we can lighten and balance the pistons correctly and without weakening the piston.

We use a 6" plain-back chuck which can be taken off the sine plates and mounted on almost any lathe so that the pistons can now be machined for any tapering work or ring groove work that might be necessary. We also furnish you with the jaws that came with the chuck originally so it can be used as a regular chuck!

Speaking about jaws: when you order the 5090 Piston Vise, we will ask what size you would like the jaws turned to. The most common sizes are 3/16", 1/8" and 3mm. We can and do turn these jaws to any size you want. You can purchase sets of jaws independently of the piston fixture; we offer them for 6", 8", 10" and 12" chucks, our part number 50904. Again, we will ask you if you want us to turn the flanges or if you want to turn them true to your chuck. If you choose to turn them yourself we will furnish you with a plate to chuck the jaws against to steady them.

We also offer jaws to hold the big end of a connecting rod along with a pin end support fixture so that the pin end of the connecting rod can be bored on a mill holding the correct center to center using a DRO. The jaws and pin end support fixture are part number RB-703. We also offer both of these as a package. For the piston fixture with the rod boring jaws and pin end support, please order RB-700.

Our Piston Vise holds the piston using the oil ring groove for accurate flycutting of the valve pockets. Compound angles can be cut by rotating the piston. Proper weight removal can be accomplished by side milling the pin bosses.

Available with 7-1/2" jaws to allow machining without the removal of the connecting rod.
