Back it the day..........Well, I made all kinds of stuff. A real "Iron monger". Made these fittings for the Navy. I understood they went on some kind skiff of something. Got welded on so they could burn off most of the galvanizing.

Pretty simple except for the transition area. Had to make a bottom die for the 4-B with a round cut-out angled down at 30 degrees or so. So we'd hold it flat and start hammering and pushing it down to the correct angle at the same time. Ya just can't get that shape any other way. Then edge it and flatten some more. Not as tough on the operator as it sounds, but ya really gotta HIT it if you don't want it kicking up on you, really counter-intuitive.

That's the bender I built 30 odd years ago. That was a hydraulic steering gear for a big ship. I used to bend 4" mild steel cold with it. and 6" alloy hot.

Notice the follower bars and that I add more as it gets closed. Bend one end a little, flip it over and work the other end.

I really like a rotary table bender for this kind of stuff.

Tucks in real nice if ya got the length figured right. I love it when things go just the way you plan. In the above picture there is also slug the pushes against the flat (look close!)

Yes, there actually is a designed in twist to the legs!

Think we did about 800 of these at the time. We got real good at it.

Neat stuff Grant. I take it the little block on the right side in the third picture is pushed by the followers and is not pinned to the table. That's quite the bender. Were jobs like this profitable? It seems like they should be as they are small for the big shops but impossible for the fab shops. I have gotten a few jobs that were modified for machine shops to be able to produce them when a steel company closed down their blacksmith shop. The modified version was failing in use, I then produced a better product (not as machine shop shiny) and made really good money probably for less money than the machine shop was making them for.

Very nice bender you had there! Any idea if there is something similar around the SE to build one? (not many shipyards in Hotlanta) Looks like two cylinders with some sort of rack gear?

Known as a hydraulic rotary actuator. Yep, the piston was a chunk of 8" with one end sticking into each cylinder. The middle had gear teeth cut in it to turn a pinion. Turned 360 degrees. Pinion shaft sticking out the top was 5" diameter with three 1" keyways.

I would guess the thing to do is buy a big ol rebar bender.. Like the one Grant sold me:bounce:
