Small heavy duty brake I built to make all the fuselage attach fittings for 4 Bearhawks.

I like this, for a couple of reasons.

First, being I made one similar to yours, back in 2010, to bend up Horiz Stab Spars for a Zenith 701 type copy.
The 30 inch length of the HF unit would not accommodate the eight foot lengths of the spars , I had to fabricate. I had to overcome the brakes tendency to put a bow in the middle of the spar, and engineer a center force pressure application. the longer brakes could not keep the brake pressure consistent due to the "give" of the angle irons. Happily it worked!

Secondly and more importantly, (to me), is that this embodies the flavor and mindset of experimental aviation. You had not built this before, so it (for you) was a learning process which is what EAA [originally] was all about.
Making do, with what is on hand, rather than just plopping down a few bucks and walking away not having learned anything.

It took into account;
The concept, design and execution and troubleshooting of an idea,
with the satisfaction of doing it yourself, and learning things that can be extended into other projects.
Kudos to you !

A $1500 Tig welder to make a$50 brake? Seems legit. For $1200 you can get a 8ft box/pan brake that you could sell for what you paid. Those things keep their value. 6.

USA I made a 7 foot brake from one, 21 ft. X 3" X 3" X 1/4" angle, works great ! 8.

Also I'd rather put that \$1200 into the plane than to tie it up for some time, in a one time use tool. Again, it's about learning and experimenting.
not plopping down a stack of cash.

A good box/pan brake is NOT a one time tool if you are plans building (not buying a kit that your simply match drill).

It will absolutely hold its value. So even if you sell it, you're getting your money back.
