I needed to make some shims for the breech seal on my Mendoza. I used the computer scanner to take a picture of the seal, and used the software brightness, contrast, and sharpness controls to get clearly visible edges. After cutting and pasting several copies of the image, I printed it out at 100% original size. (No "scale to paper size" - original size.)
I chose plastic from a soda bottle for material; this I double-face taped to the back of the printout:
I nibbled out the insides with a paper punch:
And cut the outsides with scissors:
After peeling the paper off, it fit pretty well:

I haven't got it back together yet - still working on lapping, polishing, and choking.
There will have to be a shift in POI. Before the shim, the barrel was visibly angled upward ("anti droop"), and now it's nearly horizontal. |
