Here are some more pictures of the assembly of our metal bending brake project. The first picture in this series, shows that the notch on the bed leaf has been completed. This should occur right after you complete the welding of the parts that is shown in the assembly 1 pictures . As you can see from the picture the part of the machine that I created in assembly 1 is going to be used as a jig for assembling the bending leaf assembly. After completeing the notch, I use 1/2" bolts to attach the bending leaf handle to the pivot point bracket. These bolts are only temporary clamps, they are not the final pivot point pins. What you cannot see very well from the picture are the washers that I am using as a spacer between the handle and the pivot point bracket. It is very important that these washers (spacers) are installed. If they are not installed weld shrinkage will make it so that the pivot point bracket and handle have to tight of a fit with one another. What I do is use a thick washer during the jigging process, and replace these with a thinner washer when I install the actual pivot point pin. This way there is some play so the pivot point move freely. You could just sand or file the thicker washers down some, I have access to the thinner washers though so I use them. Also, you could just remove the thick washers and not install anything, but this would give you about an 1/8" of side to side movement. This movement wouldn t effect the quality of your peice that you bend with this machine once it is completed.
Ok, here is the first picture in this series.
