you said the valve hits the piston when the valve is almost fully open(in this sentence "binds up intake valve on piston just before top of intake lobe".Īre you dead sure the valve is hitting the piston? Or, what do you mean by the top of the intake lobe? When your at, or near peak lift.the piston should be roundabout 110 degrees below top dead center, and running away from the valve. Local track is 1/8th mile, should i step up to 4.56's?Īnd any comment you would like to state, just please back up with reasoning. Given the motor, what converter would you run? I currently have a HUGE PV clearance issue, binds up intake valve on piston just before top of intake lobe.

I plan on running the Pro systems SV1 on it when I get it ready to run.

#CNC FLYCUT WHEEL MANUAL#
I will be running manual brakes, no power steering, and have room for long tube large primary custom headers with full exhaust and cutouts. My main goal is to drive the truck to the track and run respectable times. I would like to get the truck on the street and drive it here and there on a weekend. I am running 15x14 aluminum wheels on back with 31x18.5 hoosiers. I have gutted the inside of the dash out, cleaned everything off the firewall, removed the wheel wells and other than that-it is stock. I want to keep my interior, put racing seats and a 10pt cage in it. Before I start with the engine details I will summarize it's intended use. I have a powerglide with a trans brake and no converter. I have a 2000 Chevrolet S-10 Extreme extended cab step side that has been cut in half and I installed a S&W Racing 4 link backhalf kit with a ford 9 inch rearend with 4.11's. It takes lots of passes to accomplish, but at least you do get a helical tooth at the end.I am a college student that is graduating in a couple months, I have been building my drag truck out of my first truck i ever bought in 2005. Using the lathe/cnc mill method can give you a pretty nice gear. But it was only for some old snowblower, and the guy was happy enough to have something that would go round.
I have to say the gear I made looked more like a faceted jewel than a gear tooth. This still doesn't create the helical twist at all, so then I'd have to fool around with some more lateral offsets to cut the corners of the teeth a little bit, as the corners interfere with the worm, because they are not given helical clearance. I used a method where I tilted the tool to the helix angle, and then after rough milling all the teeth, I'd move it over one circular pitch each side of center, to simulate the multi-tooth cutting action of a hob, which has several teeth engaged at once (not only the center one is doing the cutting).
That being said, I have done the odd crude gear in the past like that. The worm won't mesh, and can never contact the wheel tooth properly. I've also used a similar technique on a cnc mill, using a tapping cycle to drive a flycutter down a helix.Īngling the head on a regular mill won't give that tooth its helical twist, it will be a tooth with all features aligned with a single plane. IMO, that is probably the best way to make one if you don't have the right machinery. Several years ago, Metlmunchr had a thread on the old forums about cutting a nice worm wheel on his lathe.
