Thanks SD, your efforts are greatly appreciated. 

Here ya go Mmc:I feel like an idiot, but I can't find the video.
I was surprised and a wee bit humbled to see my name in there at the end, part of the V4L family, being such a newb and all. That made me smile.
Well I was going to use a cutting wheel on my Dremel. But I forgot that I had snapped the securing screw head off working on another project a couple of weeks ago. So I used my trusty hacksaw and a vice.
I have a question... can you take the filler material out to see if it's burned, and if it's not, then put it back in?
