  • Metal Brake: Let s get started.

    Well, since ROCK stated that it was ok to do this project on the site, I think I will start out by giving you guys and gal the dimensional drawings that I put together. Please be patient. It is going to take a few days to get them on to this site, because during the week days my computer time is very limited.

    To start off, I would like to let you know that this is a very simple design that I came up with at work. I needed to manufacture a high number of handles from stainless steel flat bar. My boss allowed me to build the brake as long as it did not take me to long. So the entire brake was designed and built in 5 to 6 hours using what ever mild steel scrap that I had in the shop. So parts of this machine can be made from thicker material or a different structural shape. All this would mean is that you would need to adjust the dimensions on some other parts. Even though this is a simple design the machine should last for quite a long time. The current machine that these drawings are based on has been in use for 4 years.

    From this first drawing you will see that the part was made from 3/16"X 3" flatbar. This part could be made from angle iron, because in the end I weld another peice of flat bar to this peice to create the second leg of an angle iron. This way I have a surface to clamp to the table for holding the machine in place. For my demo I was thinking about increasing the thickness of this peice to 3/8", so that I would have a better bearing surface for the pivot pin. However, since this is Hobarts website I will use either 3/16" or 1/4" and we will call this a project for a HH 175 . This means that I will weld the entire project up with my HH 175. Well, enough chat here is the first drawing. Sorry, they are all going to be in pencil on graph paper. I don' t have a CAD program.

    IMPORTANT: This project requires 2 of this part.

    Sorry, Rocky D I made a mistake when I tried to change the name on my picture for you. Which ended up making me have to delete your post so that I didnt have my brake post on here without an attachment once and then a second time with it. Oh yeah, the reason there is no picture is because my work doesn t allow cameras in the plant and I can t take the machine home because it is company property. It is a long story. Maybe I ll just make one real quick this weekend, so that I can get a picture posted. And then after that work on the demo machine that is going to be a slower process. Anyway,my Dad would probably like to have one.

      I understand, Dan, thanks for the reply. Now at some point, will you write up a bill of materials, so I can start scrounging material?
