I do the same for my 1/700 ships. All you need is a sharp or flat nosed tweezer. Works faster then the bending tool. I think its only useful for large pieces but for that I use my steel ruler and plastic rods. I've seen this guys work uo close first hand when he came down to KL.Guys thanks for the responses.
About the bender, I am watching this video here, this chap is bending all PEs by hand, and these are a 1/700 ship. It's possible ! And crazy !
I have received my small bender today, the quality of the constructions looks quite good I think.
Cheers,
Richard
