Homemade adjustable stock / comb thoughts?

[Rafn]

I've an ebay stock I'm planning on putting on a loaner, but the butplate had been taken off, and the one off the broken one it's replacing doesn't line up right.  I think my cost was about $20 for the stock (someone had sanded the stain / squirrels off an old glenfield stock), so I'm willing to cut into it if anyone has good ideas.

I think coming up with an affordable DIY solution might be handy on and off the line.  So far my thoughts have been revolving around threaded inserts and a rod with normal thread on one half and reverse on the other.  I know I've seen this as a stock item somewhere, but can't recall where - shouldn't be too hard to cut into barstock if all else fails.

That sounds like an interesting project. I might suggest looking at old Stevens target .22s for inspiration, I seem to remember them having a screw adjustable butt plate and comb.

Cheek weld: U shaped piece of plastic with slots - put threaded inserts and threaded rod in stock and wingnuts on the outside of the U.

LOP: work out a solution where 1" is removed from the stock is about 3" from the rear and come up with a system that will allow it to be lengthened or shortened to suit.

Goal: to create a publicly documented solution entered into the common domain, thus allowing anyone to produce it without worrying about patents.

Why not cut the stock right behind the pistol grip. Attach a "pig nose adapter" and screw a collapsable AR15 carbine stock onto it. Add a cheek piece and you would be good to go.

A cheaper way would be to use screw adjustable table leg feet. Insert them into the wood stock, use a extra nut as a lock to keep them square.

Thanks - the table concept might work well as a starting point - it's basically the same concept.  Will take a look at the hardware.

If you use rods to move the pieces up and down you will need to develop a way to drill the holes parallel to each other and to the stock itself.

To each other so they do not bind as they slide in and out/ up and down.

To the stock so they stay in alignment with the sights not pushed out to the sides as the parts are moved.  In production stocks these are probably drilled while the stock blank is still rectangular before it is shaped.

How about Velcro?  Use it to attach pieces of wood or padding to make the adjustments.  Cheap, infinitely adjustable, reverseable. Just a thought. For cheek piece: stock, attach fuzzy Velcro, sharp Velcro,shim(mousepad), fuzzy Velcro, sharp Velcro atteched to a nice chunk of raw hide or leather for the top.  Add shims as needed.

I think the velcro solution sounds perfect.  LOP could be solved with spacers with velcro on either side.  Comb with different pads.  No permanent damage to the newer plastic loaners (use a rubber or silicone cement for the velcro).  Cheap, reusable, and effective.

Might just start looking for more takeoff factory stocks and replace the wood on any loaners.

Will work on the wood stock solution as well (boring parallel holes is easy with a shopsmith).  Just need to find a bandsaw to make the comb cut.
