Trumpy.,
I have the hickey bender and this what I will recomonded to you is make serveal small step for each bend and do not try to bend too much otherwise you will make a kink in there.
The numbers of "hits or movements " on hickey bender it will depending on the amout of bend the last 90° bend with 3/4 hickey it took me 22 hits to make a nice bend I know it is alot but that is the only way you can do that without kinking it.
Otherwise a standard conduit bender will work just fine and it will be done quick.
There are few tricks I done with electrique benders and hydrallics { it will be much easier If I can catch ya in the loft { chat room } and expain how this work out }
Merci,Marc
