For heads from 1967-on with the 6 locating knobs the GB 705 boring plate is required or the heads must be milled flat.

This tool requires a perfectly flat parallel surface for the feet to bolt down to in order to provide parallel seating surfaces for the cylinders. Additional cutter heads can be purchased and set to needed sizes eliminating the need to reset over and over again. I, personally, recommend purchasing the 15/1600cc precision head center GB 702-855. See GB 702's for precision centers for specific size bores. Semi-Hemi cutting for properly lowering the CR can be done by purchasing our Semi-Hemi cutter.Ĭomes with universal centering device GB 702F, and 2 GB 701 cutter heads for you to set at the needed size. Flycuts and/or bores heads (up to standard 92mm) for more CR or larger bores and bores cases for larger (up to standard 92mm) cylinders without removing studs. The cutter heads are designed with proper mass (much thicker than our competitors) to provide smooth cuts for boring or just a simple cleanup flycut on a used head. Once set the cutter head screws onto the driving shaft. Uses adjustable cutters in the blade holder. For those who do not have a friction controller on their drill press spindle, a second collar stop can be used for this feature. It has a positive shaft collar stop for exact duplication from hole to hole depth when flycutting. I installed a National oil seal in the base's bottom that keeps cuttings or contamination from damaging these bushings and/or the shaft.

Features rugged cast aluminum housing with all 4 feet, 1-1/2" case hardened (heat treated), centerless ground shaft that is running in silicon bronze bushings which provide years of trouble free accurate cutting. It had to be a rugged precision tool that would provide years of shop use with a quality drill press, as we did not have access to a milling machine.

I developed (originated) this tool in 1961 because it was impossible to find anyone with a mill to bore the case and heads so I could install the larger Corvair pistons and cylinders on my 40 HP engine. Location: Home » Catalog » Tools - Gene Berg Flycutter » Tools Tools

If you are capable of nothching your own pistons, PM me, I can get you going in the right direction.Apparel American Hardware Pistons and Cylinders Flywheels and Clutches Gaskets and Bearings Cranks, Rods and Gland Nuts Oiling System Valve Train Pulleys Carburetion Programmable Fuel Injection Electrical Parts Cylinder Heads Traction Bars and Mounts Gear Sets, Tranny Parts, Suspension 5 Speed Kits Special Tools, Tech Manuals If not, do it before you take it apart.Īssuming you don't own a mill and the tooling to flycut the valve pockets, take one of the pistons to your local machine shop that has a piston vice and a milling machine capable of being set up for doing valve notches. Since you have already set the deck height on your race engine, you should have already numbered your pistons and cylinders. Do the other 3 pistons in their respective holes. 010-.020 deep dimple into the piston top, but not so hard as to knock the piston down the hole and turn the crank. What's the heck is a medium hit you ask? Hard enough to put a. Slide a tool called a transfer punch down the valve guide, and punch it with a hammer with a medium hit. This is where the piston-to-valve will interfere the most, and where you should mark the valve centerline on the piston top, so the machinist knows where to put the notch.

Put on the copper gasket, torque the head to at least 50% of spec (no valves). First confirm TDC of your degree wheel or degree pulley.

Mock up the crank in the case, dial in the cam, have at least one rod, piston, and barrel in place, torque plate snugged in place. That's where you want to set the piston during the piston marking with a punch process.

Most normally aspirated race cams (the FK8X series falls into that category) are such that the greatest valve-to-piston interference happens at 10degrees before or (after TDC). No valves in the head, but piston in place (no rings), and a degree pulley or degree wheel and 1" dial indicator. To mark the piston tops: Important to do with YOUR heads and pistons, the deck set, the copper gasket in place, the cam dialed in where you intend to run it. Check, if it's good, then do the other 3. Plan on cutting on one piston shallow, checking, then cutting that one piston again. Make sure the pistons you chose are thick enough to support that depth, some are not. 200"-.220" deep with 1.4 rockers, that cam and CB044 heads with 40cc chambers.
