Simon -
You have a lot of talent. I was more than impressed with your template illustration for the Grizzly leather grip. These are the types of patterns that can be made to be exactly like the originals, which can then be used to reproduce more accurate replacement items.
I have just scanned an original 5-Line 1959 Strike Plate that I removed from a broken bow. Figured a scan would give you more of an exact size than a photograph.
I enlarged the strike plate to give more detail, actual maximum width is 2.08”, actual maximum height at forward edge is 1.47”.
The exact width of the lines is hard to measure, but appears to be very close to .030”.
The exact thickness of the leather is also difficult to measure because of glue residue. It is between .045” and .050” thick. I know that is not the proper way to measure leather, but measuring by ounces has not proven exact for me.
The thickness of the leather at the bottom of the line is .040".
Simon - I hope this scan helps you or someone else in their efforts to create a Replica of an Original 5-Line Strike Plate. I’m certain you will get better as you make more of them.
If anyone needs any scans of any other original Bear Leather strike plates, let me know, I will help if I have them not originally attached to a bow.
Note that this strike plate is slightly irregular at the top left. Leather work is seldom as precise as some metal work.
