The right pop-rivet used for the right application is not weak or flimsy =

at all. They are extremely useful and effective in many situations, and =
=3D
very strong when properly installed. Several stainless-steel pop-rivets =

on each "hose-clamp" attachment point would work better than screws. =3D
You have a knack for such things, and would probably re-tighten the =3D
screws periodically as a matter of habit, but for most people the =3D
pop-rivets would be a better solution for a trouble-free fix. =3D20

Greetings to the collective brain,

I have a question: Which pop rivet should I use to reattach the hose
clamp holding the stainless steel band around a kiln lid - aluminum or
steel? The old spot welds gave out on one side and I am getting
cracking of the lid near the hinges. This is the art center's small
bisque kiln and needs to be kept in working order for a bit longer.

I'd think the steel rivets would be better for the hot kiln, but I bet
the aluminum ones are easier to pop.

I'll get to the fix soon, but right now I'm helping install this
year's Rising Eyes of Texas show. This is my favorite show of the year
(not counting the clay show in Feb). I love to see what the younguns
are up to. Come check us out if your in the neighborhood.

It shouldn't be a question of which is easier to pop. I am a little =3D
concerned about the shear-strength of the aluminum rivets, but am =3D
equally concerned about corrosion of steel rivets. If it were me, I =3D
would go to the trouble to get stainless steel pop rivets. If I =3D
couldn't get stainless, I'd use the aluminum pop rivets and use three on =
=3D
each end of the hose-clamp bands. =3D20

Taylor:
What material is your band made from? Steel? Then use steel rivets.
Reason?
Roughly the same expansion/contraction characteristics, and no corrosion
from dissimilar metals during those heating/cooling cycles (with the
attending moisture down there in RockRock.)
I found out that steel/aluminum wasn't a good mix in FL, with the salt air.

Just my 15-1/2 cents, adjusted for our current "no inflation".

people promised
wasn't going to be snow. Where's that lying groundhog??!

Taylor, here's what I did, has worked fine for many years, and is,
in the end, I think, more durable:
Just drill an undersized hole and insert a standard sheet metal screw
(zinc plated steel). It will bite into the firebrick a little, but who
cares,
it might even make things more stable. Should the screw rust and
corrode over the years, just replace it with a new one - no muss,
no fuss.
I am not a fan of pop rivets because they are so weak and flimsy.
I can usually figure out a way to use a screw or a bolt to get the job
done and it is free because there are always screws lying around.

Dear Taylor Hendrix,


Assuming the working temperature on the outside of the kiln is not in exces=
s
of about 300 deg C I would choose Aluminium Rivets. Steel rivets will
corrode under the influence of water vapour in the atmosphere and from that
which diffuses through the refractories.

Taylor --

Of course you don't want corrosion ...

One of the issues involving corrosion is galvanic charge.
Different metals generally have differing charges, and
you will get somewhat to a whole lot more corrosion
with different metals than with the same metal.

The difference is governed by atmosphere (fewer
problems if dry and salt-free), heat (hot is worst)
and the difference in charge of the two materials
(a wider difference is more of a problem).

I used Aluminium on our venerable Olympic on the body as well as the lid- n=
o=3D
problems, and that was more than 100 firings ago!
