Hi All,

I just wanted to show my variation on a pretty common homemade engraving tool.

Some of the things I wish to engrave are not very flat, and not amenable to being made flat, think AR mag wells.
So I wanted a rotating spring loaded engraver, because drag engravers don't go deep enough in some situations.

Mine is very similar to many others you might see by googling them, but I did do a couple of things differently than most of the ones I've seen. That would be using a commonly and inexpensively available ER 11M straight 10mm shank collet chuck for the sliding portion of the tool, these are in the $10 range on eBay. I also added one of the MSC clamping collars to the shaft to make it TTS compatable.

I decided to go with an external spring, so I also added a 10mm clamping collar to the chuck shaft to give me spring tension adjustment without removing the tool from the spindle.
