I'm in search of a rail bender which will handle codes 250 and 332 brass rail. If you have one and are interested in parting with it, or, if you know the whereabouts of one, please send me a PM. I'll respond with my email address.
Will, I have a Lindsay single-rail bender for loose rail. I have also used a borrowed Train-Li dual-rail bender (assembled track). This one does a great job of smoothing curved rail joints after installation of 6ft flextrack . But, it is expensive--currently $335.
You are welcome to borrow my Lindsay for loose-rail , if you are assembling your own rail/ties into sections. It is set for code 250--I might have rollers for 332, but not sure.
The Trainli bender comes as either code 250 or 332. There are conversion kits to change from one to the other.
Also note they sell a keep parallel clamp to allow only one end of the flex track to change length.
