[TowerTalk] Bending Aluminum

[Grant Saviers]

It won't take a lot of tonnage.  12T probably enough for the width you 
might need.  20T surely enough.  Easy to buy  @ Harbor Freight or from 
some auto parts stores, and a very useful tool for other press work.

The challenge with the usual antenna 6061-T6 is using the proper radius 
dies as T6 is fully hard and will crack if bent on a sharp radius die. 
Other softer alloys are a lot less challenging and of course less strong.

Here is a quality supplier with many die set choices, you need to have a 
press that fits the width of dies and arbor plates better than the ones 
from HF.

I have several of their products but use die sets I welded up from hot 
roll angles for bending steel to 3/8 in my 20T press.
