    Those answer questions well. I'm sure handle length and gauge capacity are linked to restrain bending heavy material, especially on a finger type brake. I don't know how tonnage for bends are calculated formula wise.
    Compared to press brakes, those concerning die widths and radius, are published broadly.

    Combined with satisfaction in such a project, you saved considerable money. New and used market 24" & 36" finger brakes are rarely capable of 18 gauge full length, yet run $5 or $600. Once you hit 48" the thickness increases and those run more, not only in total cost but value per inch. Beyond that, maybe 8' and 10' they might be $5 or $6000, but in reality cost less per capacity then smaller brakes.
    Why?
    Many potential customers [as home shops are on the rise] haven't funds or room for a big apron or finger brake.
    Supply & demand rides again.

    I just fell short of submitting as next of kin to be added as beneficiary to your estate; seeing that 24" hook scale..
    Until stair gauges holding TWO rules together became apparent .

    Did you notice the HF calipers wrapped with electrical tape?

    Well, noticed of course. But nondescript compared to world's only 24" hook rule.
    I was all ready to send a fat check. In today's liberal climate, I've adopted an identity of a millionaire. However, my bank statements disagree...
    No joke. Something happened, long narrow [1/4"] tape measures used to be common. I have a little side gig working in a pump shop. When boring and facing shaft or bearing sleeves, lengths aren't so critical. A nice scale or tape marked in 32''nds is ideal, most are called out to + or - 1/64th. And a hook rule unhooks easier in a narrow bore!
    Regarding stair gauges, I recommend them all the time. The hex shape works as a dead stop too, as do keyway clamps.

    This little pump shop by the way, has warranties matching/ exceeding the big guys, exploiting build techniques that are not common to that industry. Owner is 38 yrs old, with more than a dozen full time employees, a fleet of well equipped trucks, and impressive customer list.
    As one of his earliest and continuing mentors, I'm justifiably proud.

    I have the same calipers, and the same electrical tape! The battery cover screw strips.
