Ken, do those motors have a small fan on the back end of the motor shaft? If so, you can box them and let that small fan draw cooling air into the box.

Might be easier to make new cylinder heads with simple spring-loaded valves, and disconnect the cams. (camshafts are not used in real compressors).

Ken, that engine's camshaft/valves are set up for 4-stroke, while a compressor/vacuum will be 2-stroke. I think it will make a very low efficiency vacuum pump that will waste a lot of electricity.

The diesel "chargers" are likely to be turbochargers instead of superchargers - difference is that one is turbine driven (exhaust gas) and the other shaft driven. Be careful of trying to use a...

You can also try the dairy industry for vacumn pumps - used for the milking machines. Around here they are vane types in the range 2 to 5 kW. They are fairly easy to re-build.

Did you clean out that old P4 machine to make sure that it isn't running extra stuff inside....like looking for a LAN connection, looking for updates to iTunes and other timewasting stuff like that?

You might have the inch based "diametral pitch" system. A 20DP pinion with 20 teeth will have a diameter of 1", and a circumference of 3.1416" (79.8mm). That is 3.99mm per tooth.

The collet and the nut are supposed to be "clipped" together (before putting a tool inside). They can be unclipped, after slipping the tool out.

I agree with Alan; move the spindle nearer to the Y-motor - it gives a better "connection" with the y-motor forces and it allows you to work further off the 0,0 end of the table (if you have tall...

Standard Daimler-Benz practice on truck engines is to use "heli-coil" from the very beginning. This is apparently quite common with other companies and applications.

I have little experience with those slides, but one lesson I did learn was to cover the screwholes in the slide bars so that the seals can work correctly.

As per the drawing M2 10 110 W, I advise to avoid a good butt joint, if you are planning to weld them together. The welding wants a space to be able to penetrate.

You can just load some weight on each end of the gantry to see if it pushes into contact.
