I found my heating element was rubbing against the drum so I just pushed =
it toward the casing am the rubbing noise stopped.

My noise is definitely coming from the tip of the drum. It did go away 
after some vegetable oil was applied.

Hmmm - there really isn't a bearing to lube or anything. will investigate.

    Make sure the noise is actually coming from the front.  On my hottop =
I had the same issue where the gold screw no longer "fixed" the noise.  =
Upon a closer inspection I noticed the noise was coming from the left =
side.  After removing the drum I noticed the heating element had bent =
towards the drum and once it heated up it would actually touch it, =
making the noise - I just bent it back in place and no more squeak.

Well, peanut oil is better than some, but it's by no means the best

smoke points:
   http://www.goodeatsfanpage.com/CollectedInfo/OilSmokePoints.htmOf course, any oil will eventually go rancid, heat just speeds up the  
process, so maybe it doesn't make much difference for Hottop use. I  
really think a high temp, food safe grease would be better for this  
purpose; although, I've never really felt the need to lubricate my  
Hottop. I haven't been following this thread too closely but,  
although some seem to have had problems with the heating element, the  
only rubbing sounds my Hottop has ever produced are when the spindle  
gets off-center.

I'm not a chemist, but the never-to-be-questioned internet says that 
mineral oil is inert. :-)
I'm guessing that the chemical reaction in vegetable oils that results 
in a rancid taste might be oxidation, which probably wouldn't happen 
with mineral oil.

Oh, well, I suppose I should have been more specific. I wasn't  
thinking of mineral oil when I said "any oil", just vegetable based

Well, soybean oil probably isn't that uncommon by that definition,  
but anyone with a Whole Foods near them, should be able to obtain  
refined avocado oil. Good for stir frying since it doesn't have much  
flavor of its own but is mostly monounsaturated fats.

Soybean oil is the most common commercial oil.  There are modified veg. 
oils that come in 5 gal drums used for frying that consist primarily of 
hydrogenated soybean oil.
I have used it as part of a team frying malasadas for fund raising for a 
little church in west Kauai. Hydrogenated veg. oils aren't healthy but 
they are more stable for frying and lubricating.

The end of the drum "axle" is supported by the metal plate that screws onto
the end of the hottop.  The "pit" in the center is where one gets the noise.
I would recommend peanut oil.  It's what I use, is of course food friendly,
edible even, and has the highest resistance to heat of any common / natural
food oil.

11) From: B. Scott Harroff
What I meant by "common" is what most folks have easy access to at home or
in the local grocery store and "natural" as being normal/unrefined oil.
If we remove the "refined" oils from that list, and the uncommon ones like
Grapeseed oil, avacodo oil, and soybean oil, I think one is basically left
with peanut oil and safflower oil.
