Thank you guys for the great response so far! Per Strider's suggestion, I'll just update my build progress on this thread to see if all the work on those drawings will actually pay off!
Right from the start, the PDF prints at the perfect scale, just like I'd hoped:
I started by piecing together what cutouts needed it, then proceeded to trace them out accordingly:
An hour's worth of cutting and several more worth of sanding left me with these pieces:
Not having to eyeball the individual layers of the feed plate made for pretty light clean-up to make them stack just perfectly for gluing, which can also be said of the butt stock layers. Speaking of gluing:
The Gathering of the Clamps there is the result of my choice to glue all three layers of the feed cover at once, which can either be attributed to my impatience or my excitement. Mounting that finished piece first will make it possible for the rest of the plate to slide together with ease, so hopefully this will make for a decent starting point once the stock is finished.
Meanwhile, the sheer 1-1/2" thickness of the butt stock will make for quite the sanding adventure as I begin sculpting it to shape once the wood glue is fully cured tomorrow.
My goal today was to finish cutting out and prepping the wood pieces, which I think went well. Word day aside, tomorrow I hope to completely sculpt the butt stock, as well as prep the thinner detail pieces (cut from thin sheets of acrylic plastic) and get them all glued in place.
Again, thank you for the great response! I hope to hear back from all of you who requested either the PDF or CAD file with whatever critiques or suggestions you may have!
