Thankyou very much James, I appreciate you comment and I certainly agree that no matter how small the part is, it can hold vital information. Sometimes you don't know what a small part is until you get to certain stages and things just fall into place. I am at that stage right now. There are some small round wooden blocks bolted into the bin parts I am doing and I had no information as to their use until David Dunlop asked me if I had info of each bin use. After getting a Vickers ammo tin and putting it into the original part, I then realized they were spacer blocks for the .303 tins and could be unscrewed for the .5 tins. So that was great for me to find a use for them and now I will be making some of them as well. So a big thanks to David for asking the question
Anyway I had to make the rear door that has a pressing in it so I decided to make a press set for them. I need 1 for each tank and there is another door above which after these are pressed out and completes I can easily modify the press set to make a smaller pressing for the above door and then just de-weld the material for another use. As it is only aluminium, it will probably only take 15 or so tonne to form it and my pressbrake is a 40 tonner so there will be plenty of power.
