Doubling the crank speed is of very little benefit as every practical motor vehicle has to have gear reduction from crankshaft RPM to wheel RPM. Your engine would need an even higher gear ratio reduction. My experience with the patent office is they will grant patents with gross obvious flaws...

The absorption curve is just the maximum the dyno is rated to be able to absorb. As long as you are under the curve you should have no problem. At 1800 RPM the dyno is rated for almost 3 times your 700 HP. The only potential problem I could see is if you need to do some testing at very low...

Generally speaking, freewheeling is considered somewhat dangerous and not recommended. You can pick up considerable speed plus your brake vacuum boost and power steering are reduced. Not to say I've never done it. I was driving to the '79 Watkins Glen GP in my Mustang very late at night. I...

I loved it when we acquired a smaller company and I tried to trace back the changes thru their ECN forms. Most typical revisions said "Changed Dims". I kid you not. ---------------------------------------- The Help for this program was created in Windows Help format, which depends on a...

You need some form of seal otherwise the fluid will wick along the pins. I've seen designs with round pins and an o-ring on each pin. I've seen designs with the electronics encapsulated in various materials and the seals put around the encapsulation. There are may ways to skin this cat but...

For plastic mold making the Society of the Plastics Industry (SPI) Moldmakers Division has a scale for the surface of mold tooling that is similar to what you are looking at. They sell a plastic plaque, the SPI Mold Finish Guide for optical comparison. However, I don't see a grade that I can...

I despise using dual dimensions. I've been designing metric products in the US for over 40 years and only use dual dimensioning when somebody holds a gun to my head. Suppliers will try to use the secondary dimensions for layouts, inspection reports, etc. You will fight round off errors...

The customer doesn't want a cam or detent feature. I was hoping some one could dig up a spec or example of a bayonet connection. But I can reinvent the wheel. ---------------------------------------- The Help for this program was created in Windows Help format, which depends on a feature...

I'm considering all the aspects of the slots, not just the stop. If the two start slots are off the mating part won't even start. And the horizontal legs need to be pretty co-planar or it won't turn. ---------------------------------------- The Help for this program was created in Windows...

Sure one side will hit first but the second can't be too far out of position or it won't work at all. ---------------------------------------- The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

I've got a part with a bayonet feature on one end that another part will lock into. I'm not sure what is the best way to ensure proper position of these features to the ID bore and to each other. The mating part will slide in the bore and have a cross pin that has to slide in the slot on both...

Good find. I'm hoping most users would get those horrible sheet metal covered lug nuts off once and replace them with proper one piece nuts. Really surprised some enterprising bottom dwelling scum sucking lawyer hasn't created the largest class action suit in history and sued every car...

I have my doubts that EV Batteries Are Perfect For Storing Solar Power. The lithium batteries typically used for permanent storage are a different chemistry than EV batteries. EV batteries are a much greater fire hazard so clustering them together isn't the best idea. They also can't be...

I'm assuming these are both more efficient and less expensive than photovoltaic solar panels. Any idea how they stack up? I only see big farms of PV arrays in the east, never seen one of these in the flesh. ---------------------------------------- The Help for this program was created in...

I agree with Jassco. Assuming the new material has passed the engineering requirements and the old material will be used up or scrapped, there is no need for new part numbers. The alteration records will show the history and the ECR will show the reasoning...
