I know they're not Lee Enfield based rifles, but here is a post with a couple of my other projects:

What would you say if I said that I had built a bullpup rifle stock that converted a rotating bolt action into a straight pull?

"Rubbish" I hear many exclaim. "Can't be done without a CAD suite, CNC machine shop and 3d printer!"
Well, feast your eyes below!
The scope is affixed with tape to test the height of the scope and mount arrangement, see if the packer I had put in was thick enough.
The base rifle is a Marlin XT17

And the scroll cam

My Compulsive Engineering Syndrome was certainly playing up the day I started that one...

The mechanicals are done, I'm presently building the woodwork for it.

And here's the other stock I built.
New Zealand Black Beech (Nothofagus Solandri, iirc)
The shape is as close to the Thompson/Center Dimension as I could get it, as I tried one and it fit me perfectly, so I copied the buttstock shape with this.
The base rifle is a CBC Model 122

It's still a bit thick in places and surprisingly heavy, so I may slim it down a bit yet.

So yeah, I've got a pretty good idea of just how much work I'm putting myself in for...
