425 F might do it.  Alternately you could burn the crud off with a propane

Can I add my voice to the "remove it with mechanical means" chorus?

Clamp down the saw, improvise a turning rest, switch it on and "wood turn" it.

The least it would do is wreck the finish, leading to another belt 
failure in short order.  So we'll try the toaster oven first. If that 
fails, buy the new pulley.

The oven did slightly anneal the brass I used for gib strips in the 7x12. 
Not fully, but enough to control 90% of the warpage as I fitted it. ISTR 
i let it soak around 24 hours each time I did note the warpage was 
getting out of hand.

I'll waste a try anyway if and when the weather reads the calendar and 
discovers its supposed to be spring already. 

The cookstove has a cleaning cycle, gas stove though. The problem is that 
the wife's COPD would make the smoke pretty bad on her. 

She's supposed to go to the doctors offices today, to check on her broken 
leg, but with the deck ramp only 1/4 finished (I'm still making a hole 
in the deck flooring for the ramp) & with 4" of wet soggy snow on 
everything, that isn't going to happen over night. I can move the snow, 
but not the slick wood, and I've 4 or 5 days of good weather to get it 
reassembled yet. And my back isn't able to brute force the wheel chair 
up the 2 steps at the driveway end. Even 3 days of good weather would be 
a miracle. Damned nor-easters, 4 in 2 weeks.

Thanks Chris.

Re: [Emc-users] Getting a burned up polygroove belt out of a motor pulley. Need chemist expert

2018-03-21 Thread Bruce Layne 
The self cleaning oven would probably do a good job on the belt residue 
but would almost certainly result in damage to the aluminum's material 
properties.  The self cleaning oven temperature is around 500C.  A quick 
online search seems to indicate 6000 series aluminum experiences 
recrystalization somewhere in the 250C to 300C range, and the effect 
becomes pronounced around 400C.


https://www.researchgate.net/post/Temperature_of_recrystallisation_of_6xxx_aluminum_alloys

A pulley might have sufficient design margins to tolerate the exposure 
to high temperature without subsequent failure, although if there's a 
key slot it may fail.  I wouldn't heat 6xxx aluminum to 500C in anything 
close to a critical application where I needed the original mechanical 
properties.


I'd probably go with a version of the previous suggestion.  Have the 
bandsaw motor spin the pulley and use something like an ice pick to 
mechanically remove the rubbery goo.  I wouldn't push the tool against 
the rotation in the manner of a wood lathe.  That seems like a good way 
to catch the tool in the workpiece, have it spun around and jabbed into 
your arm.  I'd let the tool dragging on the workpiece so it wouldn't 
gouge and kick back.  The material removal rate would be slower but it 
should be a lot faster than removing the pulley, using solvent, baking, 
etc. and then reinstalling it.


Good luck!

So as not to stink up the house, would a $20 toaster oven do?  It goes up
to about 425F. It would stink up the garage instead that way.

But not till warmer weather as the saw is in an almost unheated shed and
it will take a bit of time as the lower drive wheel will need to come
off to gain good access to the motor pulley. The shed is not well
insulated, so I keep the heat set to just above the dew point to
discourage rust on the machinery in the winter. We're on the inside edge
of the current four-easter, and its a bit chilly out, and still snowing.

Thanks.

My bet is the toaster ain't going to work.   What will work is if you have

you might want to also clean in the oven and run a self cleaning cycle.

What is the pulley made of?  Steel?  Aluminum?  Plastic?

It's the motor pulley.  That means you can spin it up by simply plugging in the 
motor.
I'd try to turn the stuff out of the grooves using a "lathe tool" made of 
something softer than the pulley.
Hand-held, probably with an improvised tool rest, like on a wood lathe

Gene, can your Sheldon swing the pulley?
I had a similar situation recently with belt residue build up on my PB
motor pulley.
I tried all sorts of chemicals, acetone being the most effective, but that
was still not very promising,
so I resorted to mechanical means. I chucked the pulley up in the lathe and
ground/filed
a bit of acrylic to fit the v-belt groove and used that as a scraper, and
finished up with abrasive
wool soaked in acetone. It worked like a charm, and the pulley looks almost
new.

I know you have a micro groove pulley, but I would think the same method
might work,
and the chance of damaging the pulley is very slim. I think you would have
to get it
really hot to burn it off, and it may just be a gooey mess at lover
temperatures.

Cheers,
Kurt

So as not to stink up the house, would a $20 toaster oven do?  It goes up 
to about 425F. It would stink up the garage instead that way.

But not till warmer weather as the saw is in an almost unheated shed and 
it will take a bit of time as the lower drive wheel will need to come 
off to gain good access to the motor pulley. The shed is not well 
insulated, so I keep the heat set to just above the dew point to 
discourage rust on the machinery in the winter. We're on the inside edge 
of the current four-easter, and its a bit chilly out, and still snowing.

Thanks.

I’d pull the pulley off and through it into an over set to 450F for a couple of 
hours.

[Emc-users] Getting a burned up polygroove belt out of a motor pulley. Need chemist expert

2018-03-21 Thread Gene Heskett 
Greetings all;

I have a Rikon 10-325 bandsaw. Trying to cut a block of alu with a blade 
thats had one side of it dulled, the blade turned and bound in the cut, 
and burned the drive belt, a 240J into the motor pulley. Rather 
thoroughly welding the kevlar backing into the pulley.

Does anyone have a recipe for some panther piss that will clean it out, 
or am I stuck buying another pulley from Rikon's parts dept?

Thanks.
