Hello kind people,

Title says it all. I have some syringe needles that are perfect diameter for the turnbuckles in the cockpit of my WNW SE-5a. How do I cut it, keeping the tube rather intact?

Thanks for any ideas, instructions, or rambling patter.

Although Im sceptic the snapping might work with syringes as they are soo hard. However I prefer brass tubing which nowdays can be found in very small diameters at a cheap price from Lionroar and Griffon.

To avoid denting them I usually have a piece of streched sprue inserted and then use a razorblade and roll the tube against the tablesurface while applying pressure until it cuts off.

Cheers

Cutting wheel on Dremel or Moto type tool. High RPM,slow feed of wheel to tube. WEAR SAFETY GLASSES,FACE SHIELD, OR GOGGLES!!! Vise the tube 'good' side with about 3mm extended. Cut tube in a manner where the wheel rotation will take spoil end AWAY from you. Cut a skosh long so you can lightly hand file to final length. Gloves and long ,buttoned sleeves are not a bad idea either.
HTH,
Rick
