A Proper Introduction To Doc And MULE

Nice. Really like the air compressor idea. Good job.

My name is Doc Sprocket and I care about your lawn tractors... :p nice vid though good idea using the forklift plug as a slave cable

Mother of wiring, very cool to see it all on video, as i am a fan of that. You do damn good for being new to youtube. Keep it up!

Thank you kindly, fellas!

nice to see a vid of MULE. looks like your ready for everything., except if ur coffee runs out   

Nifty military themed "fix it in the field" accessory package.

Some great ideas there for all of us. Sometimes sifting the chaff for pearls of wisdom is difficult... and sometimes it's easy. Thanks for makin it easy.

Yep.

Thanks, fellas!

Very cool, get a hold of a higher quality camera, and you will be golden! I record off my phone because thats all i have, but it shoots 720 or 480 when focused. so it does ok.

Thanks. Actually, the camera is quite good, but my internet sucks. I been doing what I can to make file size manageable. So, quality suffers.

One thing though doc.... I ain't seen one pic of a coffeemaker on the thing... Where's the love man?

Awww Ya beat me to it Lawren! Needs a coffeemaker, maybe exhust heated???

Anyway, Bravo Doc. I'm a cancer survivor too. Aint it great to be alive?!!!

Damn straight, my man!

Coffee maker? now y'all got me thinking about that. I have a little 12v 1 cup unit that I've had in my work vehicle for a couple yars. Fantastic for when there wasn't a Tim Horton's close enough to the job site... MII, maybe.. LOL

Cancer sux! I lost one friend to it already and another lost her breasts, and yet another is still fighting breast-cancer. She used to be a patriots cheerleader. The up-side to it is that after her double masectomy, her husband (my buddy) got to pick out her new set for reconstruction LMAO!!!! WOOHOO!! yeah, I'm a pig    

Exhaust, my friend... Exhaust will heat up a cup-o-joe right quick! No need to tax that little alternator any more than it already is lol!

In fact now that I think of it, I'm wondering if it would be possible to use exhaust pressure to pump up a tire. Maybe not high pressure, but... Lots of volume there. I bet it would be easy to rig up an attachment to blow up "tube" for "tubing" or an air mattress for camping.    But if it pops inside tent I guess you could die.      

A lot of farmers in south America run a VW flat 4 on 2 cyl, and use the other 2 as an air compressor to run pneumatic lifts and attachments.

It's just a big air pump.   

The thing about the air pump is... The compression stroke. Horribly inefficient, if one were to repurpose an engine as a compressor. I would thing that to do it right, one would need to reprofile the camshaft, and play with valve timing.

The way they do that without major mods is they put a pipe with a check valve in the spark plug hole and remove the exhaust pushrod. They close off the intake runner (so they aren't getting gas in the compressed air) and drill intake holes in the head for air... usually a 1 inch hole with a push in breather. The preferred heads for this are the porche heads, the intake is easier to mod, but Ive seen it done with all types. If someone wants to do it, they'll engineer a way.

Both solutions would work great. Even in a pinch, you could get good pressure from the exhaust if sealed up correctly. To be most efficient, I think I'd have the cam re-profiled AND use the check valve in the sparkplug hole with no exhaust valve pushrod. Compression on every stroke....
