What is your plan for removal when the thermistor fails?

This is the exact reason why I did not use High Heat JB Weld. I just took the time to wrap the thermistor around the block, inserted the heating element, then wrapped kapton around the two tightly.
Thermistor no longer moves.

Unfortunately for me I'm down in Melbourne.
I think at this point I may just follow the procedure and materials outlined in your thread, seems most logical.

Its good for a few weeks at a go and I used to use it before I settled on the process I outlined in that thread and it does work fine - but I got sick of thermistors falling out when I was rough with the cables after a few weeks of use...

In fact if you were near Canberra - I have a 98% full tub of the stuff I'd part with...

Oh, that thread is handy, danke!

Now if the rest of us would just be as meticulous as Adrian. smile  It just seems to me I read somewhere that fire cement was used successfully.  I just can't find the post.

So Serin.... what kind/brand of cement are you thinking about using? most 'cements' can be dissolved by various substances the main thing is to pick one that does not harm the heater block.

Not to mention that delicate thing called the thermistor smile

Fek.

Yep wink

I wonder if there isn't a way around that though?  Maybe it it could still be yanked out or something.

Hmmm from what I've learned it seems the only viable option for removable would be chipping away at the stuff gradually, but even then one probably could remove it all without damaging the block.
I suppose i'll have to improve my kapton-ing skills.

Somewhere is a post that adrian did about how to do it right.  Basically pull the heat cartridge out wrap several times with the thermistor in place then cut the hole for the cartridge.  That's how I do it and it looks clean and holds well.
