Wow!! Hardware from Lithuania (Field Target Shop) arrived today and it is awesome. There is nothing there that is ever going to break. All mounting hardware, including screws, mounting plates, rods for adjustment and screws for adjustment are included. There is nothing to buy before installing and using.
The parts you see and the rubber material for pants, that the parts are on top of, came to 200 Euros, including delivery. That is just over $300 Canadian and I do not think there is a better deal out there.
Now I am going to have to put a better effort and more time into getting the wood ready.
