Good day, CGN!

After a couple of years of owning my Norinco M305, I decided I wanted a wood stock to replace the poly stock. At the same time, I had to choose between funding new perimiter drains around my house, or buying a quality walnut stock. The house won, so the question is, how do I do this without spending too much?

To do this, I needed a duplicator. They're about $1200USD used. I watched a Midway USA video, and ran to the work shop to see what I already had to get started.

Now, sanding to #600, cutting the action:

Bedded, and 6 40/60 coats of finish. Almost done!:

Thanks, to you, and everyone. When I find another free image host, I'll put better photos up. I am very, very happy with the part of the wood I selected for the stock, and how it glows with the finish. I want to make this a new hobby, but I need more firearms now!
 
I'm thinkin for the price of a custom stock...... a guy could quite easily build that duplicator ;)
I have one very similar that rides on rails..... seeing the nifty garage door track set up you have there and gives me ideas to modify mine.
I've done a few stocks on the rail one I have but there is too much tool chatter for fine work..... that rail set up will solve the problem I'm thinkin.

curious.... care to share the approximate cost of that DIY duplicator?

And to answer rebelent too - I didn't keep track of the time when the router first touched down...but I remember heading to the workshop at 8am, and I was back in the house for tea at 11am. That was enough time for set-up, carving, take-down, and included changing router and stylus bits 4 or 5 times.

The build of the Duplicator took three days while I was working night-shift...so about 3 hours per day @ 9 hrs total, including welding. However, I had been planning the process in my head for about 2 weeks, and every time I had an idea about what to use for each component - I'd toss that onto my work bench so everything was relatively quick to assemble.

Costs
In electricity (to runs tools, lights and welder) and weld wire = $14
The rails are cut from one rail, salvage.
Brackets for rails, salvage.
Rollers for carving rack cut from old nylon cutting board and shaped on a drill press (I don't have a lathe), salvage.
Rack was made from scrap (bed rail, plumbing pipe), salvage.
The stylus was made from scrap parts, salvage. (used a tap and die set)
The work bed was made with scrap wood, maple for the rails, and cabinet plywood for the base, salvage.
The arbors for mounting the work was again made from scrap metal, spare bolts, etc., salvage.
The gears were copied from a dirt bike sprocket onto a nylon cutting board, salvage.
The only thing relatively expensive was the router bits. The structured tooth tungsten carbide cutters did an incredible job on the red narra, with no burning. The tool cost? All my tools have been acquired since I was a teenager, much like most of us I'm sure.

As for the time into sanding and finishing the stock after it was removed from the machine - an hour here and there over a week = max 8 hrs. The action was cut with a dremel, using a 1/8" to 3/16" X 1.5" structured tooth tungsten carbide cutter. Constantly dry-fitting the action to make sure I didn't remove too much wood. In a couple of spots, I did remove a little too much. A little silicone mold-release, and lots of DEVCON Epoxy Steel (6 to 8hr working time, 16 to 24hr cure), everything was bedded, leaving appropriate room for the moving parts of the action and moving parts under the barrel.

Cost of the epoxy = $6.99CAD + taxes x 4 tubes.

I have some improvements to make. For example, the lateral movement of the rack is by bushings, and dry graphite lube (which could dust-off into your work!!!) will be modified to operate by nylon rollers. I will stack two plugs, and cut into a 1" v-roller, and make four of these. Four rollers on top of the bar, and a nylon rail underneath to keep the rollers seated, and give clearance above the work.

Does this help at all?
