In my shop I have a single spindle duplicator and I like it very much. Does wonders for building a collection of patterns.

There are 2 3D printers outside my office right now,...and coupled with a scanner they are a mind boggling piece of equipment but only if you want a plastic or composite stock,...unfortunately ( or fortunately) we like to have our stocks made out of nice wood, and that would require a pretty sophisticated 3 axis cnc with tool changer, and even that would not come close to replicating the subtleties required to feel your way through the cut on a 3K piece of walnut as a good hand guided duplicator can.

Joe Cole of Cole's gunsmithing was doing something similar,...I was told by the lady there he is back to doing it by hand, took too long the other way she said

Since we've drifted a bit from Joe's original question to more of a "how dey do dat?" thread, I thought I'd post these pics from CSM again.

This first one is what I beleive is their hydraulically powered tracer mill (powered pantograph equiv) for one stock at a time. This machine is similar technology to TrueTrace and HydroTel mills I've used more than 3 decades ago. You can see the pattern and the stylus in the front position. The rear position is where the product would be. This type of machine appears to be a 4 axis; 1) left/right, 2) in/out, 3) up/down, 4) rotate pattern and product. The toolholder and cutting tool is not in the spindle in this pic.



The pictures below are of a 10 spindle machine that is CNC or DNC controlled. I beleive this machine was also 4 axis and was machining 20g RBL stocks at the time. Note that not all spindles are being used.



Just looking at the inletting/frame to stock shapes, you can tell the RBL was designed to be machine inletted from the start.

my single spindle machine....it has since been further modified to do rough cutting automatically with just the last .100" or so on the outside and all the inletting done done by running the machine by hand.

Not so bad if they already have a pattern done, if they don't then mega money for engineering / drawing and code for your duplicate.

If you have a lot of "EXTRA" money lying around!!!!

I have seen a couple of examples in person and they are very nice,but not real cost effective for one off's unless you break stocks on a regular basis.

Customer reports have been mixed over the years. I suggest you Google the phrase "Great American Gunstock" (with quotes) and make your own determination.

Mark,
I have 2 high condition original guns in the shop....too high of condition to put in the duplicator unfortunately. Maybe we can work out a deal. I can make the pattern to original specs and duplicate it. I have a trade in mind if your up for it.
Steve
