Default How To Make Baffle Tension Rod

I am at the stage to make the baffle tension rods. I am having trouble threading the ends with the threading dies. Is there a technique to get the dies started?

Better yet, is there seller for these ready made tension rods?

Thanks.

The tension rods are described in the picture below.

I started with a harbor freight die. No joy. Bought a high quality die and it
T was a piece of cake. Some have used threaded rod in lieu of having to thread the ends. Others have used safety wire inside plastic tuning in lieu of the rod.

I struggled on the first set, as i only had a bench vice and couldn’t keep the rod from slipping. Second set done on a lathe and very easy. Find a holding apparatus designed for round items. Chuck the rod in your drill and clamp the drill chuck in your vice.

Or pre cut them and mail to me with a bottle of wine and will thread them for you.

I see the washers the wire goes around to keep the stainless wire from digging into the aluminum baffle, but what is that black goop for?

I’m using DMC Safe-T-Cable instead of safety wire but everything else the same as Dan. Only 200 hours but everything is still well secured.

Permatex Ultra Black, aka Loctite 598. In this case a dab kills any relative motion due to vibration.

The safety wire does work. However, your local aviation department at Lowe’s or Home Depot will have threaded rod that will work also.
