Title: Help with Polyimide Tubing Size
Post by: prepcik on January 17, 2015, 02:56:23 AM

What is the right inside diameter size for polyimide tubing for 1/32d scale rigging lines?   I have a source but the sizes are given in fractions of an inch.   Given the cost for the tubing, I'm reluctant to experiment.   The smallest size listed had inside diameter of 0.0050 inches.

Any recommendations would be most appreciated.

Regards,
Paul

Funny you should ask!  I just got my order of this today, purchased for that very reason (1/32 turnbuckle bodies).

In Metric, the ID is 0.32mm and OD is .47mm.

Des' article on making turnbuckles suggests 0.5mm brass tubing with an ID of 0.3mm.  The poly tubing I got was the closest to those sizes I could find.

You've got to shop carefully as the prices vary wildly.

It depends on what diameter line you are using. 30 AWG works nicely with .12mm line, it's too small for anything bigger. I use 29 AWG for the .14mm "Worlds Best Rigging line" stuff that Steven was dispensing awhile ago.
