How To Bend Sheet Metal For A Snow Plow

3 jacks would have worked better for re adjustment reasons.

How to bend sheet metal for a snow plow.

To bend the metal you will need a metal bending fabrication tool. Driving a big chevy up onto a pipe to bend it. I am an a p and taught sheet metal at local trade school. Well its almost done.

Homemade snow plow from a hot water tank part 1 5 after the cutting duration. Cut out the shape of the plow accounting for the bend curve from your steel sheet using a metal saw. Well you are at the right place. I just need to bolt the cutting edge on when it comes in.

Bending aluminum accurately is an art. Be precise on the bottom edge and top edge. I used 14 ga sheetmetal a 2x4 and a hyd jack with a chain wraped around the plow and the metal jacked down using the chain on top of the jack. If you want to have the snow roll in front of the plow just increase the bend at the top of the plow but keep the attack angle of the blade around 18 to 20 degees.

A straight curved blade will simply have a straight edge on the top and bottom but a shaped blade that throws snow to the side will be much wider on one end. Looking at a cross section the outer 60 of the alu will stretch and the inner 40 actually shrink making very accurate bends tricky so if accuracy is important you need to adjust your bend lines accordingly. Depending on whether you want the snow to be thrown to one side or to both sides you will need to bend the steel into a curve to match your criteria.
