HF Sheet Metal Brake
I bought a HF sheet metal brake and I am making fingers to make a more versatile.
I bought some 3”d1/2” flat bar at the scrap yard and would like to know what sizes would be best to make the fingers.
The total width is 30”, I have made 1,2,3,4,5,6,12 & 14 inch pieces so far.
The fingers will be held with “C” clamps like the pice that comes with the brake.

Re: HF Sheet Metal Brake
Make them in sizes that you think you will need.
My 4ft.Tennsmith has five 2",six-3" and five-4''

Re: HF Sheet Metal Brake
I would say make them in stacking cumulative sizes kinda like very coarse gage blocks.
1", 2", 4, 8, etc.
That allows all widths from 1 to 15 by increments of 1" with no redundancy. Wouldn't be as rigid/strong, but maybe throw in a 1/2" if desired for very light work that doesn't work out to integral inches.

Re: HF Sheet Metal Brake
If the widths are all integral multiples of one inch, it will be impossible to make things like a 4.5"-wide box.

Re: HF Sheet Metal Brake
A 4" finger will make a 4-1/2" wide box just fine, I you are that worried use two 2 inchers spaced apart .
Besides you cannot make a 4-1/2" box with a 4-1/2" finger it will be oversize by the material thickness.

Re: HF Sheet Metal Brake
You are going to be better off with pressure on every part of the crease.
I think we all knew that material has thickness, and I didn't say "4.5" outside width."

Well,I guess I've been doing it all wrong for the last 45 years thanks for pointing that out.SteveHGraham wrote: ↑Mon Nov 04, 2019 9:11 am You are going to be better off with pressure on every part of the crease.
