Long Lifting Tubes for your Gear Jacks
All Gear Jack models ship with standard 6" long lifting tubes. They work well for many aircraft sizes but for larger airplanes, and especially when using Wing Tube supports, you may need longer tubes.
With the exception of the Lifting Tube Tangs, Gear Jack Lifting Tubes are nothing special. They're simply 1/2" EMT (thin wall electrical conduit) that you can buy at home improvement stores most anywhere. If you want to make your own Lifting Tubes, it's easy. Here's how:
- Using a steel rod or similar blunt end shaft long enough to reach the back end of the Lifting tube Tang, drive the Tang out of the existing Lifting Tube. It will be quite tight, so take your time with many small taps of a hammer.
- Cut the new length of EMT and deburr both ends with a file or sand paper
- Align the rear end of the Tang on the end of the new Tube and carefully tap the Tang into the Tube until it seats. Take care when driving the Tang into the Tube to keep it straight. Lots of small taps are better than whacking really hard.
- If the tang does not feel tight, remove it and apply some glue (CA, epoxy, or other waterproof glue) to the inside of the Tube and re-install the Tang.
- If all that seems like a pain, you can just buy new Lifiting Tubes and get back to flying. :)
