Terry,
They are very easy to make and I'm a metal man myself..... a few pics, I,ve used the original as a template on this one but in the past, I found it easier to get the right lengh first then once its a nice snug fit clamp it on the bayonet, use the holes on the bayonet as a guide to drill through or mark the wood, mark around for the shape and cut etc, I only used a a small drill size at first as I counter sunk the holes then drilled the correct size for the screw,if you need to make the counterbore deeper then its lot easier having it allready started.
