Topic: Need glue recommendation for busted chaff lid (7 msgs / 141 lines)
1) From: Sharon Allsup
Entropy decided to help me clean up after a roast, and knocked the
chaff filter to the floor.  (More like I hear the thump that means
kitty-snuck-onto-counter-while-I-wasn't-looking, I yell at home "OFF
THE COUNTER!", and he leaps off kicking the filter to the floor
....aaaarrrggghhhh).
So now I'm hoping one of you can recommend a glue that is food-safe
and not going to outgas poisons and stuff at high temperatures ... one
of the little black plastic tabs that secures the chaff collector lid
to the chaff collector base broke off when it hit the floor.  The lid
now sort of "surfs" on top of the column of air - really cool to
watch, but spits chaff everywhere now.
It's item #2 on the i-Roast diagram - the screen lid to the chaff filter:http://www.i-roast.com/pro_02_01.phpI can jury-rig something with clips, but it'd be nicer to just glue
the thing back on properly.  And since it gets HOT, I need to know
what kind of glue can handle those temps and be safe around food or
kitchen.
Suggestions? Besides never ever naming a cat "Entropy" again?  Thanks.

Sharon:
Since it's in the exhaust (and presumably used in a well vented roast =
area)
you don't need to worry much about toxicity . . . there won't be any
significant outgassing after the first roast anyway.  None of the
cyano-acrylates ("crazy" or "instant" glues) will stand up to the
temperature . . . your best bet is an epoxy (there are plenty available =
that
are "high-temp" . . . for 500F or above . . . that should be enough).  =
The
"problem" will be bond strength at those temperatures . . . and not =
knowing
what plastic the broken part is made of means there's no way to "look it =
up"
before trying (a package that says "bonds to most plastics" is =
encouraging,
but no guarantee).  Test the glue (for adhesion) somewhere else on the =
lid
before trying it on the broken tab.
If you can identify the plastic there are plastic "welding kits" =
available
also (and you can "test" for adhesion with the various rods in a
non-critical area, too), but it is hard working with small parts.  And =
the
kits cost far too much to justify for a one item fix.
If your time is worth anything it is probably cheaper to just order a
replacement part . . . (the probability of success is higher, too )

Good to see you now realize that was really, really asking for it, Sharon.

My experience trying to glue plastics back together that are actually under 
some stress indicates that Deward's suggestion is best, Sharon.  Besides 
the annoyance of some expense and a lot of time wasted trying to get it to 
work, you must add the possibility of it coming undone at a critical moment 
and causing more extensive (and expensive) damage.  Having appliances 
suddenly start disassembling themselves could initiate a grab for or other 
attempted intervention that inadvertenly knocks the whole thing over. 
Umm...yes...that *would* be the voice of experience speaking.

The thing costs all of $19 bucks.  Call hearthware and they will sell you a 
new one.  I bought a second one last month so I could drill a hole on my 
first one for a thermocouple.

Unfortunately, Hearthware claims they're out of stock on the
replacement parts ($10 for the lid only, $28 for all three
chaff-collector pieces).  Sorry, I should have mentioned that in my
original post.  Normally what I'd do is go ahead and order the backup
piece, and experiment with gluing while it was en route.  I do have
two pieces, so in theory could reconstruct two of the three tabs that
are broken.
I'll hit the stores tomorrow and check on high-temp-resistant epoxies;
still working on a jury-rigged way to clamp it without blocking
airflow or burning things.
Thanks!

Try JB Weld.  They claim to have been used for pistons on diesel
engines.  I used it on the chaff collector on our Freshroast a year
ago and it is still holding.  Not sure about it being food safe, but
it is heat-resistant.
