This thread is to Update a previous thread of mine: http://www.bbq-brethren.com/forum/showthread.php?t=174146&page=1 where I introduced a small steam powered Rotisserie, this time We have redesigned it to be large enough for a whole Lamb/Hog/Buck(African Bucks, Springbok, Rooibok, Waterbok. Not quite large enough for a whole Kudu though :-D )

I Include a link to the YouTube Video for this updated version:

This was made by some of my final year mechanical engineering students studying at North West University Potchefstroom South Africa, I think they made a pretty slick project with a cost of about 1000 USD...

Anyway enjoy, our South African National BBQ holiday is almost here!

Neat idea, I like the sound of a steam engine.

Very cool. In one of Aaron Franklin's TV shows about "Pits" he shows a big rotisserie pit that he has and jokes that he would like to build A steam powered rotisserie. I hope he sees your students work.

That's really cool, all you need now is a train whistle to blow.:shock:

Today we added the rack to fit the roast, and will post an update with the results of roasting a whole animal. I really happy with the student's results, great group of guys!

Very nice! I would hope you have redundant safety temperature and pressure relief valves and the steam cylinder is rated at least 20% over the max pressure you plan on using. What a cool design.

We have a pressure release valve that opens at 2 bar, the steam chamber is made from a scuba diving air-cylinder (they are rated well above 300 bar). There is also water level indicator to prevent running the system when water level falls below 33% of the pressure vessel in order to prevent flashing of the water to vapor that could cause a catastrophic failure. The plan is to have the pressure relief valve open onto the briquettes thus cooling the heat source and in such a way have a "mechanical control" system

It's finally happened! There actually is someone crazier than me.

This is-- by far-- the coolest device I have seen in some time. I am working on the drawings as I write.

Getting ready to get an outdoor Braai with the Carson rotisserie, and this would add the finishing touch.

I would be happy to share our manufacturing drawings ;)
