rotisserie
I might be in the wrong place but here i go.. I am looking to build
a rotisserie to cook about 100lb pig or so.. I have seen some
electric rotisseries that worked pretty good and they seem pretty simple.. I am just not sure of the size of electric motor i would need to be able to turn a pig pretty slow and for several hours..
any help would be appreciated , have a good one. I have also not
seen any plans on one for that size..

1/4 hp will be plenty but you will need to find a gear reduction unit to slow it down enough. I am not sure where to find one,, new would be easy but to salvage one might take some searching.

You could look in Grainger or check here. http://www.surpluscenter.com/ If you find a reduction unit at 60 to 1 or so its still going to be too fast but then you could add sprocket and chain on the output to come up with the right speed.

ok , i have come with some numbers.
115 rpm 40 in lbs 60:1 45.00 (duty cont)
35 rpm 50 in lbs 50;1 45.00
(duty cont.)
29 rpm 475 in lbs 60 99.00
(this says duty 15 min) ??

I am not sure about the duty cycles but at less than 475 I would think that one would run continious just fine. The other ones do not have near enough power. Now if you put a larger sprocket on the rotator and a small one on the unit,, maybe 4 to one you are going to be gaining some more torque and the 99$ one should work. Whhops, I see the link, ok, same still applys. At 200 inch pounds it wouldnt work, but sprocket and chain,,, like bicycle chain would give a lot more power and slow it down to the speed you want.

thanks,
Recap, you think the 200 in lbs with a sprocket and chain
would work? The sales guy emailed me and told me that i
would need the continous duty.

If you can keep the load from being all lopsided it should work. If you geared it 5 to 1 you would gain a lot of power and give 9 rpms. If you gear 10 to 1 you have 4.5 rpm and it certainly would have lots of power. Yes, you need continious. I would think duty cycles would be rated at full load and the less the load the longer it is going to last so gear reduction should increase the lifespan. You could use pully and belt but chain would be far superior in both efficiency and lifespan. Chain is low friction compared to belts.
