Looks like there was a server blip or something this weekend, because two whole threads about the LAB12 driver are missing.  So I'll re-link a previous thread here that I think may be of interest to some.  It has excursion and thermal measurement data of the LAB12, showing its most common failure mode.  Thankfully, this thread wasn't lost.



Maybe the server overheated....

Looks like it could benefit from my ultra cool 8000xl pro2. It's designed to chill air to absolute zero and throw it onto the server to keep it from overheating. The design is proved to increase server speed and add extra oomph to it.

Hi Evan

Now that fan is cool, is that you in the photo?
I have casually been looking for a large fan like that to attach to a big old engine I have.
Have any idea where an old one could be found?
Having a big fan off in the distance during a  summer BBQ is nice both for the breeze and mosquitoes don’t like it.
The engine is a 1915 Fairbanks Morse “Y” 15hp oil engine. It has an 8 by 12 inch bore and stroke, has 4 foot diameter flywheels with a 7 inch wide rim, it weighs 6600 lb without the trailer and on a good day, takes 45 min to start by hand.  This engine runs at Full speed, slower than most car engines idle (@350RPM) and can be set down to idle at about 70 RPM where it makes a very nice Thump…. Thump…. sound from the 5 inch exhaust pipe.
Best,

Tom

The system will not have its proper response, proper excursion control or ultimate efficiency with the covers removed.  Make the covers.
Best,

Tom

Arrow Engines is in Tulsa, and the mechanical engineer I consult with most often works for them.  You would probably love their engines;  Check them out.

Hi Wayne

Hey, thanks for the link, they say they carry parts for Fairbanks engines.
The narrower flywheel brothers of the one I posted were also used in oil well service.
If they had enough of a load (to make them hot enough), they could run on raw crude although I would imagine you would need to start it on kero or diesel.
Mine starts easiest by hand (if a typical 45 min is easy) on Kero and runs on diesel once warm (it has no load, my interest in a fan as a load).
So far, I have been able to make the minor parts it took to get it going although a place to get a real head gasket next time would be cool.
Thanks.

If you ever need anything from Arrow, call Monte Vogt.  He's a mechanical engineer there, tell him I sent you.  He and I have been friends for years, one of the best motor heads I know.
