Homemade manual square tube bender

Are you noticing any flex in the side plates or are they staying tight against the center die.

I haven't.

As you see "arms" supports the package on vertical direction.



Also i have to take back my previous post.
If you look those pictures closely, you notice that i mounted that lower edge support plate wrong side up. blaah...
That's why i got different results with the widht.


Also i made a little improvement, just drilled a hole through the whole thing, now i can lock the used "slot depth", and get similar results every time.



Now when comparing deep, or shallow slot. Only difference can be seen from this picture:


Somewhat similar, only difference is that deeper slot handles little bigger force before it starts to loose its shape.

I think that the result is now somewhat best that i can get with the manual bender with radius this tight, and i wanted to get tight radius.
( without need to use plenty of time for bending ).




Personally i am satisfied... Now i just need to make stronger vise mount.
