Epoxy, steel filled and magnet magic

Discovered something might be used or avoided by someone besides me.
Did online search only found epoxy coated magnets, nothing else.

Been using a lot of epoxy for a lot of different things this spring.
On Peel needed 2 braces off frame spine projected sideways to hold up the front
of a tray. Polished galvanized gives acceptable under seat finish.
So took care not to get epoxy on top, then put super magnet disc on top
to hold brace till set and worked a treat, till >>.

No matter how careful to glob on goop - all clean- till I turned to look
again - there were smears on top between frame and brace seam, right where
I'd left a nice bead. ugh, took a few times to see it t'wert me but the magnet
pulling a tongue out then spread out on magnet edge and brace top.

I'd gone to extra lengths to damn up against epoxy drips on frame and cradle below.
Worry was epoxy would still flow out from under the humped brace space.
Realized with the magnet as clamp the epoxy was mostly sucked up under
the brace filling the space with little excess drooling away. Cool.

For the many tiny tasks, fittings to plugs to submarine brass ring moring posts,
I found mixing a blob on bottom of plastic container with a 1" size button
magnet under kept the small puddle from spreading out too thin to use up.
Takes on raised hump shape of a padded button. Bring a magnet close
to blob and get a tongue of suspended epoxy reaching out for it. The magnet
sticks to bottom when mixture lifted, Just scope up dose ya want - hardly any need
to scrap up enough from the surrounds.

How cool is that - able to suck on a sealer adhesive, into cracks and hidden spaces
and stays put or goes where you call it.

Was pensive how to seal the swing arm ends leaking air out the top bores
of clamp bolts, how to keep it out the bolt holes and threads at very end..
Need some serous magnets to hold protective screen on tight access mower fan
so their 1st job will be to hold the epoxy to fill 1" wide thin gaps till set up.

Uoo, this is how I'll do Trixie's Combat case with proud oil drain tunnel cracked along its
length, pensive how to get enough epoxy in the fracture to seal forever without
grinding a groove and nil evidence on the surface. Al is essential transparent
to magnetic flux ya know.. Cool.

hobot,

You need to get on photobucket, your images are not working for me. I'd like to see what you are doing.

Sorry, I crash alot early on learning curves.
It'd showed up for me in preview, duh, because webshots recognized me.
Webshots was my first online photo site, last decades stuff in there.
New Ms Peel project is on photobucket.
Webshots URL only seem to show up thumbprint size so
tag URL to see bigger than life cracked case to fill in, somehow.

hobot

let's see if I get this

1. Ms. Peel is the name of your Norton Commando

2. You found magnets coated in epoxy online

3. You've used lots of epoxy this spring

4. On Peel mumble dogface in the banana patch no epoxy on top then put magnet in epoxy throuat warbler mangrove

5. goop something smears lengths drips

6. Worried about humping

7. close tongue suspended magnet lifted sope dose hardly scrap

What the hell???

Yes exactly and plan to do more of it

I think you got it!

Thank the dear lord. I thought, for a while, I was the only one.

It sounds like he's mixed some iron filings/powder in with the epoxy (or this stuff: http://www.epoxy.com.pk/steel.htm ) then used a magnet in the other side of the repair to suck the steel-filled epoxy glob into the recesses/cracks while it holds all the pieces together as an added benefit.

Interesting....

NOPE, I only mixed up off the shelf hi temp long set up time JBWeld.
Was glad I caught the magnets drawing out the epoxy on top
surfaces before it hardened. It did not happen till most
of a minute passed as I'd let the JBW stiffen up some
to minimize the drool.

Many epoxies are metal filled by various metals for various
reasons. Just keep in mind to avoid a mess or put The Force
to work for ya.

I'd no reason to ever use epoxy on ordinary Nortons
except for tail light repair and fiber glass Combat
seat pan and gas tanks. I've had handle bars and wrist
both impressed into Roadster and IS tanks. On SV650 too : (

So far 6 places JBW and 3 more with iron putty to fix Peel up.
Only 2 places for structural adhesion, coil mount and
under seat tray, rest to plug leaks of liquids or gases
in frame, air supply, swing arm and mis matched fittings.
Hmm 3 places structural - forget squid hunting
submarine moring posts : )

I tought I understood after reading MEHAVEY's post, then I read Hobot's next post and I'm lost again :shock:

Hobot, seriously, I am interested in your ideas and what you are doing with your Norton.

But, I wince every time I come to a post of yours. The strain of interpretation is tiring and I tend to lose interest too quickly. It's hell being a senior citizen.

It turns out while Hobart said he didn't add iron filings to the epoxy, the JBWELD resin he does use incorporates 10-20% iron powder by weight.

Ipso Facto, QED, (etc, etc.) Looks like he stumbled on something (megnetic properties of an epoxy) that could be very useful in managing/focusing a repair.

Maybe, because I also think he said that it would pull the metal from the epoxy.

I was thinking the same thing.... that a magnetic field left on long enough while the epoxy was still in high-flow mode ...would tend to cause the iron powder to begin displacing the resin close to the magnetized surface. Looks like it needs to be managed carefully against the time it takes to suck the epoxy into place ...vs the time that the iron powder can no longer freely move in the hardening compound.

Still, an interesting application.

Ugh sorry, brain language-words area, got scattered to -
too many new addresses, too many times to keep track of : (

I can only post small parts of Ms Peel's big picture.
If a particular question on my over powered, MX teasing
squid spanking long range hill climbing cargo mule
low rider non Norton, Commando, ask private or public.

In this post its just my surprise that the original JBW is steel filled
to become magnetic, so be aware of it for good or bad.

I left magnet under small mounds of mixed JBW for up to
30 min to stiffen up and played with how magnet
pulled taffy like strings off wood dowel and
did not see any hint of separation - from most liquid
state to set up. I think dust is too fine or is chemically
bound to an epoxy component. Regardless it does
not separate enough to affect what I want epoxy to do.

BTW, kid's craft modeling clay is really handy to
dam up epoxy flows, that leaves a shiny smooth
surface to the epoxy, if any must show to do its job.

I've a couple weird otherwise hard to solve spots that
a magnet will make easy. One is I've got to drill an over
size hole in swing arm front brace to get a long drill
in at enough angle to open volume of legs into
cross brace. Hole will be too big - chewed out ~1/2" dia.
I want a 1/4" NPT tee fitting in the cross brace but
can't tap such a big messy hole.

So will scape fresh mixed JBW inside the hole rim
and stick the fitting in with a dam of clay then ring magnet over
that to draw the epoxy into the seam and create a back
up bead inside but nothing outside, I hope.
