Here’s a duplicator machine I made. It duplicates table legs, and by putting in a small table it can do flat work as well. This will allow us to duplicate the same product over and over. If you look you will see four wooden gears in the front. The small gear on the left is an indexing gear. And this is used to position the work piece to match the piece being copied. We made these wooden gears and they work well for now. We will replace them with metal gears when we install a motor.
Once we upgrade this will cut your own pattern. Such as rope, twist or spirals on table legs. This is cheap to make and has unlimited uses. If you decide to make one like this. Then you should us a solid rail on both sides. The way I made this one is OK. But if I push too hard it will move a little. If you would like to see how we made it or make a comment.
DUPLICATING MACHINE LIVE CENTERS
Theses are some of the changes we will add to the duplicator. When we get ready to make the final product.
We removed the center gear and attached a drill to the side that is to be cut. This gives it a lath affect, by turning the spindle at the same time the router is cutting. This makes a smoother cut.
On the first pass we used a round bottom bit, this is to remove the the bulk of the wood and start to rough in the shape of the piece being copied. The piece being copied is not turning only the piece being cut.
We used a small tapered cnc bit to do the detail work, we also found the faster the piece turned the smother the cut. After the cutting was complete we took sandpaper and sanded the spindle when it was turning. This finished it the same way you would on a lath.
