Also I have a 18" bending brake from Harbor Freight. This bending brake:
18" Bending Brake (harborfreight.com)
This tool is quite the thing to see in action:
I don't own that many C-clamps. So using a plasma cutter I drew and then cutout a vertical support..
Then I welded it up and drilled some holes on the ends and slotted them carefully and drilled some holes on the end of the brake and run some long 3/8 bolts up from underneath and tested it all out..
The bending brake is now a tool worth having as we can make a bunch of repeated bends quick and easy..
To finish it off I coated the whole top or handle part with several thick layers of 3M 8115 panel bond adhesive. This process took days as I had to let each layer dry. Then I milled it down a little and the end result is a plastic feel to the handle and holding it but it is solid and heavy. I am happy with this tool now..
I had the boys bend up some sheet metal with it and they didn't have any troubles using it. Even the 12 year old that couldn't put his shirt on right was able to negotiate the Harbor Freight bending brake without any troubles.
Harbor Freight is alright. With a little help Harbor Freight is better. And they are selling safety glasses right now for $1.49/pr.
