[Wierd problem with sander]

Just to let you know, got a new cap for it today and all is well, so thank you guys for your help.

Well......I pulled it apart and found the Capacitor, its a 0.22uF, but the exact one is no longer stocked anywhere, I'll have to pay a visit to my local electronics guys.  It's still strange how such a loud electrical "bang" could leave no signs of damage or smell, everything looks perfect.

Thank you guys ! very helpful, I've never come across this before. I do know a bit about capacitors through repairing guitar amps, so I know the hurty stingy ouchy thing that goes with them   I'll pull it apart today and take a look.

 

If I find anything interesting I'll post pics or let you know.

Nope its a simple belt sander, hand held, and I think it might be possessed    or perhaps its tapped into an unknown energy source and I'm about to be sucked into the vortex.

 

Whatever it is it's damn weird and a bit scary    i've never heard anything run so fast !

Hi everyone, this is more out of curiosity than anything else. I have owned an 800w "wickes" hand held belt sander for a number of years and it has been excellent for the money, its not professional quality gear but has done everything asked of it.  Today I was using it upside down mounted in my vice which I've done many times, I was sanding small pieces of plywood for a project when it went "bang", it sounded very like an electrical bang but no smoke or smell. I switched it off and looked it over but could see nothing and thought maybe it had caught something. I gave it a flick of the switch and it spun seemingly as normal, so I switched it on full, it spun faster and faster and faster till I chickened out !  I thought about it for a moment and decided it was in my head, surely nothing could make it do that, I tried again and it just got faster and faster till I chickened out again !

So has anyone come across this before ? is there some sort of "limiter" that has blown inside ? does anyone want a race ?   haha.
