Right tool for the job ..?

Ah, caution noted. I've run my cyclone for a couple of hours straight, it gets hot but works ok. Its not a dyson.

It's not the running time that is the problem. The very finest dust isn't trapped in the cyclone and gets caught by the filter in the Dyson. This gets blocked eventually (with normal use this isn't normally a problem), eventually the Dyson cuts out.

I'm surprised that it killed the Dyson. When mine has got blocked the thermal cut out kicks in to cause it to cut out before the motor overheats. It eventually resets itself.

It's a Dyson - it probably just chose that day to fail.

Apparently dead as a doornail with a nasty burning smell. Don't know a great deal more about it and I'm not familiar with how the Dyson's work exactly, but that sounds like a burnt out motor to me.

Hi Chris

TOL's are a warning that something is wrong. Every time a TOL trips it gets a little weaker, so it trips at a lower level and takes a little longer to reset.

Long term bye, bye motor.

For this and an earlier post...

Also a limit to how much fine dust your lungs can handle. Something of a balancing act.

Re. sparks in a vac... If you think that's a problem, you've not seen the sparks from the armature of my angle grinder then.

FYI ... it turns out to be more simple and clean that estimated. I tried scoring the lines with a Stanley knife, which didn't do an awful lot. I then grabbed my trusty little plaster hand saw (little 6"-ish saw that I bought for cutting down some coving without pulling the wall/ceiling with it) and proceeded to score further on the existing fine lines.

I found it did this nicely so I tried being a bit more aggressive and actually sawing with it. Low and behold ... it cut with the greatest of ease in a lovely straight line about 15mm deep to the next layer of whatever's behind my plaster. Did this on both sides (about a 10mm channel) and then just leant on the bit in the middle, which easily fell out.

Result - a perfect channel at the right depth all the way down! QED ....

On a not altogether unrelated note, don't try what this fella did then !!
