Subject: stir crazy driving me crazy
I have put together a stir crazy + convection top roaster. I replaced
the plastic nut on the stir crazy with a metal one as suggested.
First roast, I hit a major snag.

The plastic shaft under the nut melts down. The nut falls off and the
stir crazy stops stirring.

I have tried refastening it once. Result was the same - more loss of
plastic and failure.

Has the spec for the stir crazy changed? Do other people have a
plastic motor shaft? Am I missing something?

Thanks!

JR

I pulled the plastic drive shaft out, and put a 3/8x2 bolt in place of it.
Unlike the pic of the mod on the link from the other poster, I just put a
couple steel spacers on top of the socket to keep it aligned. After I did
all that, a friend who gave me the idea to build one simply covered the
plastic nut/shaft with a copper pipe cap and has had no trouble. Also said
he knows people that just balled up aluminum foil and covered it
successfully.

These were among the recommended mods to the SC ~ 2.5 years ago when I
"assembled" my SC/TO roaster, and I did both -- foil covering a metal
wingnut, both protected by the copper pipe cap. My rig has been going
strong for 2.5 years, roasting an estimated total of ~ 140 lb of green
in that time. No need to replace the plastic shaft yet, but some day .

Howdy JR!
Replace the cheesy plastic shaft with a metal bolt. See:
