Re: An introduction/hello and my project.
Progress is happening, but slowly.
Picked up the CV hub that will become the center drive shaft adapter yesterday from the heat treater's
I had them anneal the bowl area so I can drill and tap it to fasten on a drive shaft flange on.
They were able to get it back to about 20 RC hardness, which will be within reason to drill and tap.
I have decided to do a complete air system for controlling the OC12 bands as well as horns and other annoying accoutrement's
The air source had to be reliable, so after some looking I discovered a company that builds a nice pump based on the Sanden AC pump.
With the power steering pump and steering box off the van chassis there is plenty of room to install the air pump in the space left.
The pump uses a electro magnetic clutch (AC TYPE)
Because this set up is not the rugged type stuff I am used to on class 8 trucks I decided to add two 100% duty cycle electric pumps to make a triple redundant air system.
With the issue of steering pretty well nailed down the issue of variable brake application came to mind.
Decided to use a double check valve in each brake band circuit and then run air from a standard single circuit brake application valve to the check valves and then to the air chamber on the OC12
The steering pressure will be high enough to lock the band and the braking pressure will be variable so braking will be controlled.
The double check on each feed line will determine what happens.
If the brakes are applied to slow down (Say 10 psi) and steering is needed and steering is activated (Pressure of 60 psi or?? fixed pressure) will override the braking and shuttle the double check on the side that's being asked to steer and fully activate the band.
With a quick release valve on each brake chamber the band action will respond fast enough for the speed this rig will operate.
Two small air valves with spring return to zero will mount on the top of the steering wheel adapter flange to run the steering.
Picked up a used Sanden SD508 compressor yesterday to get after modifying the LH serpentine bracket on the V6 to accept the pump.
The drive line offset issue has been figured out now and pretty well looks good.
I want to use as much off the shelf (Easy to get) u joints and parts as possible.
I do not want to get into specialty u joints/ CV shafts and custom house parts that are not an item that can be purchased locally.
Weather is still a negative issue as far as any serious work outdoors goes, but at this point it's far better to be getting the build drawings done and a good bill of materials knocked out.
Starting to get a pile of parts in the corner with more items coming.
Getting excited.
