Hello again, everyone.
I have come up with a way to "print your own" 3' x 4' benchrest targets. To do this, you make a template from a Tri-Fold display board that is available at Walmart, and then use that to spray paint the pattern onto some 3' wide masking paper. Here is the CAD with the dimensions:
This uses the pattern for the EBR in that there is a bigger spacing between the sigh-in targets and the rest of the targets.
Here are the basic supplies:
Here is a close up of the UPC for the board, the "critical" component for this assembly:
Mark the pattern on the top side according to the dimensions in the CAD Drawing:
I made a circle that was 2CM in diameter, and market it at 90degrees so that I could line it up with the cross hairs that will be the target so that I can mark it:
Here are the marks:
I used a 7/16" bit, but in hindsight, I would rather have used a 3/8" bit.
With the holes drilled, I came in with a grinding bit on the Dremel to smooth out the rough edges on the holes in the cardboard left by the drill bit, the reason why I would use a smaller bit:
After the Dremel cleaned up the holes
I then used a cut-off wheel to make slits up to the 2CM mark that I made earlier:
Here are the slots on all of the holes, and this finishes the template:
Flip it over, and binder or spring clamp the top of the paper to the top of the template. Let the paper roll down to the bottom and clamp it there too:
Trim the paper:
You will have to use something to keep the cardboard snug against the paper while you are painting it, so I would recommend using a small board, and not your fingers, as illustrated...
Do a couple passes for each one in a cross pattern as shown:
After the paint has dried, you can hang it up and shoot it. Here it is mounted:
Again, I hope that this helps my shooting brethren.
