Here's a candle holder I was working on today, until I got drunk with a buddy of mine and went ahead and talked with him about the one man cross cutting saws he bought. I may still be a little intoxicated while I type this, who cares.

The view may or may not notice in the top right and bottom left panels of the quadrisectioned group of images that the vaguely shaped component has a rivet in the middle of it.

While I was making the socket for the candle (sober) I pre-drilled the thing way too early and domed the shape in my swage block with a ball-pein hammer. Stretching the material like that caused the hole to become enlarged to the point it was no longer a 3/16ths hole. I had to fill it in with a little disk of metal and the flatten the hell out of it so it filled in the void.
I can re-drill the hole now and have be the 3/16ths hole I once needed. The whole idea of fixing a hole too big with a little slip of metal was all an inspiration brought to me by Dennis Frechette, or better known as DF in the shop on YouTube.
