Bending Aluminum Sheet Without Break

Time to bend or nearly.

Bending aluminum sheet without break. I found this video of stacey david from gearz that i thought some of you do it yourself car enthusiasts may find interesting. Once it is bent to around 45 degrees move to floor where you can stand on the aluminium while you bend it gives you more leverage and a tighter bend. A purpose made brake isn t necessary if you are going to be bending only a few pieces of coiled siding. So we have the bender but we aren t finished as there is another trick to getting the perfect bend.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. This weakens the aluminium and creates a fracture line. The metal should bend but only bend it as far as it goes without forcing it. Flip the sheet over and repeat.

This involves making a score or cut line on the sheet where you want the bend to start. Stacey demonstrates a technique of how to bend a sheet of metal using a vise and 2 4 s. Grab the top of the metal with the pliers as the section you heated cools off and pull towards you gently at first. If you need to reheat the metal and redo the bend.

For this you will need a table saw with a blade that has as many carbide teeth as possible and preferably sharp. June 24 2011 by admin 1 comment. Place the fracture line over the edge of a table and bend the overhang slightly downwards. The opening of the bottom die should be.

The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6. Bending these tempered alloys is not impossible but it is very difficult and will most likely require large bend radii to avoid cracking on the outside of the bend. Since the stroke depth is adjustable on the machine air bending lets you bend sheet material to an arbitrary angle without replacing the die or punch tools. Also after each bending pass work along with rubber mallet to sharpen the bend by bashing either side of the bend on the table edge.

A siding brake bends aluminum or bendable vinyl siding to the angles you want using leverage from a hinged joint.
